ford 3910

I have a late 1989 or early 1990 Ford 3910 and am searching for replacement lower lift arms. The aftermarket is loaded with every lift arm imaginable for these old school tractors but Ford seems to have pulled a fast one on us or as I call it, they "John Deered" us. The arms on the tractor right...

I have to replace a brake rod seal on a 1985 Ford 3910 and I went to look at the gear oil level plug and it looks like it has some kind of whatchamacallit threaded in to it. Is this is some kind of bleeder that I can use to check oil level without having to remove the whole thing? In other posts...

Hello, I’m having a issues with the temp readout on my tach. It basically stays in the same position all the time where all my other Fords go all the way to cold position when key is turned on. Does this sound like a bad sensor?

Hello I need the Torque for head bolts on my BIL tractor I'm rebuilding. Thanks

Hey! A few years ago my grandfather passed away. My grandfather was a farmer, but his children turned to other professions. I, his grandson, planted olives and I am trying to rebuild the farm. As part of that, I'm trying to restore the tractor he used to work with when he was alive. The tractor...

I have a Ford 3910 with around 900hrs, and one of the dash warning lights came on while running the bush hog. Best I can tell, its the air cleaner restriction light...I've pulled both filters, cleaned the outer, as well as blow out the filter housing, but I am still getting the light (seems to...

Guys, I have a 3910 tractor that I restored several years back and since 2018 keep having a strange fuel issue. So three years ago my fuel filter was getting clogged often so I drained the tank and the diesel fuel was a nasty brown color. I decided to clean the tank with vinegar which got out a...

Hey everybody. I have a well used 3910 that I have completely replaced the main wire harness on... I have questions about the main connections on the Key Switch. My old setup was so chopped together that I need help making the connections from the new harness to the switch. I need to connect...

I looked at a 3910 yesterday, with the plans on picking it up next week. First thing I noticed, the tires are set a lot wider than I'm used to...roughly 89" in the rear. My trailer is only 84" wide, isn't it just a matter of flipping the tires around in the rear and moving to the opposite...

I purchase a Ford 3910. The Auction House painted the machine. I am trying to locate the Serial Number and need some help. Please advise where to find the Stamping or Casting number. Thank You!!

Looking for some help on my 3910. I bought a used machine that started and ran but now the starter clicks and won't turn over. Is there a relay of fuse before the Starter that will prevent the starter from turning over?? I appreciate the help. It's a Diesel Unit.

Hi. I'm thinking about selling my Ford 3910 Series II but can't figure out how to date it. I've attached the serial number plate but can't find any place on line that can decipher the VIN to help me date it or identify it's HP. I think the * means they didn't include which shift it was built...

I noticed there is a spray of fuel coming out from under what looks like a cap nut on the side of my injector pump while tractor is running. It is a fairly strong pressured tiny little stream. I tried to tighten this cap nut to no avail. Tractor is a '89 model 3910 Mark II. Have any of you guys...

I have had this tractor for 30 years. I added a Koyker front end loader 25 years ago and added a Case 125 backhoe to it 15 years ago. This is an open center system. I turned this farm tractor into a backhoe is what I did. All has worked well until this week. While using the front end loader to...

As the title says I believe I may have a starter going out on one of my 10 series Fords. For the past year sometimes the starter turns over perfect then others there’s only a cluck then nothing. Key off then back on and it might turn over or might “clunk” again. At first I thought I had a bad...

Hi all, Inherited a Ford 3910. Having a lot of trouble starting it. Had fresh fuel and cranks strong, just will not start. Seems to be a fuel delivery issue - can keep it running with a few squirts of starter fluid (I know, I know). It appears to have an aftermarket fuel injector installed...

Does anyone have a Ford 3910 wiring diagram? Recently picked up a state owned unit and they replaced the headlights with blinking caution lights. Want to convert it back to headlights that wont blink. Nice safety feature, I guess, but where I use it there is no one there to see the blinking...

Bought a 3910 that needs a complete 3 point hitch setup (lift arms, leveling arms, and stabilizers). Would like to find a complete setup off a salvage tractor, but not a lot of 3910's in the scrap yard. Are there any other models that use the same 3 pt hitch system or do I need to look only...

Hello Ford 3910 owners...hoping you can help with a question: How wide is your 3910 at the rear tires (outside dimensions)? Tractor data is showing 69" but that seems a little narrow to me. I looking at picking up a 3910 and wanted to make sure it would fit between the fenders of my trailer...

About a month ago I traded for a Ford 3910 tractor that had stopped running. The young man that owned it said he was doing some light grading with a box blade and it just stopped running, and after he tinkered with it over about a month off and on, he decided it must be the injection pump. I...

Hello all, I need your help with my Ford 3910, the hydraulic from steering is leaking oil, see images in attached. Can anyone help me figure how to disassemble it to change the sealants? Best regards, Carlos Oliveira

Recently bought a Ford 3910. One of the front spindles is very loose, lots of side play. I took it apart, the bearing seems fine, but it looks like it needs a bushing. There is a sleeve a t the top, but nothing at the bottom between the casting and the spindle. I found top and bottom bushings...

Hi Folks, The time has come to install a wet line kit on my '89 3910. Its 2x4 and never had any wet lines previously. I purchased this kit: Remote Valve Control Kit | Ford 2 231 26 261 281 291 3 323 343 36 361 39 391 393 4 41 411 413 46 461 463 | | D9NNB95BB...

I purchased a 1986 Ford 3910 diesel about a year ago to replace my 1971 Massey Ferguson 135 gasser. Overall, I'm very happy with the tractor but I've got some pesky leaks I'm going to start fixing. The first one I plan on tackling is the power steering column leak. It seems I need to replace the...

Hello all, I have the FORD Repair manual for this model in pdf, but i would like to get the Shop Manual. Does any one have and want to trade, i can send the Repair Manual in pdf in exchange. Thanks :)

I've searched around and this seems to be a somewhat common issue, but I can't seem to get my issue resolved on my Ford 3910 that is fairly new to me. When the tractor is running, if I put it in neutral and let the clutch out (getting off the tractor to attach implement) I can't put the...

Hello, My tractor has an oil leakage in the entrance of the brake system in the rear axle, this oil comes from the PTO tank that is under the seat. Has anyone already had this problem? Thanks for the help

I am struggling with an electrical problem on a Ford 3910 (diesel) that I can't figure out. Symptoms: when you turn the key switch ON the dash lights up. At this point if you apply any electrical load (eg trying to start it, use the lights, indicators or horn) the panel lights go out and...

I've read several of the old posts about these issues but havent found anything thats helped so far. I replaced the sending unit today and checked the connectors. I've also checked the continuity of the wire from it to the gauge and its good. My fuel gauge is working fine so I plugged its wire...

I've recently purchased an old Ford 3910 and had some questions now that I've serviced it and cleaned it up some. As you can see in picture 1 and 2 there's a good amount of oil blowing out of the manifold and leaking down from where the muffler attaches...I should've noticed that when I bought...

The Injector Pump on my 3910 has been seeping fuel since I bought the tractor two years ago. It got worse last Summer, to the point I would shut off the fuel when parked. Primarily was leaking from the O-ring that connects the two pump body parts. When the weather got cold it was so bad that...

My 3pt has drifted down for a couple years. This past Summer when brush cutting and heating up the oil it got worse. Would "relift" every 2 seconds or less. So this Winter I decided to tear it apart. I lifted it off by hand. I don' recommend that method. It's heavy and awkward. I removed...

Ford 3910 with front end loader and rear hydraulic connectors with nothing attached. There is one valve body for controlling the bucket tilt and height and another valve body mounted on the transmission under the seat. I think this one is used to transfer hydraulic pressure from the front...

I am working on my elderly neighbor's 3910. Her family is spread out all over the country so when they come home, there is little time for using the tractor, much less using it. Anyway, I am thinking 15-40 same as any diesel. Wouild that be a good choice or what would the resident Ford folks...

Hello, I have a 1987 Ford 3910. When I lock the brakes to turn, either left or right, there is a shuddering noise. This tractor is 29 years old. It runs good. I understand the brakes run in oil. Could the brakes need attention? What happens if I do nothing? The brakes still work fine. What...

I have been searching for a Ford 3910 drawbar hanger. Ebay, Amazon both list ones that look like the right hanger but don't list 3910. Is there something different about the 3910 hanger? Thanks, Ken

I had a stick pop up and hit the area in the picture below. it is now leaking fuel through the bottom of what I assume is the carberator. Anyone have any idea how I can fix this? I have looked for cracks and cant find where it is coming from.

Was wonder if one of the guys who has wrenched extensively on these older 10 series Fords knows whether the 4610 (2wd) axle will swap into a 3910. I'm looking at a 3910 right now and being aware that it isn't really stout enough for loader work got me thinking. Thanks in advance for any info!

Thinking about going to look at a 3910. The guy wants $3800 or best offer. It has a little front end damage (says it's cosmetic) and missing the 3 point hitch link arms. They were using it to tote a dump trailer around at a cemetary. The add says it has 4 spools for hookup too. I was...

Hey guys! Been a while since I was around but I need some advice and/or experiences. I've found a sweet deal on a 1987 Ford 3910. The tractor looks great, runs great and everything works as it should. There are no leaks at all. The only hesitation I have is this tractor has a 6 speed...

Have a 1987 Ford 3910 diesel. Relatively low hours (718) for year. Recently when running (or turning switch to run) both gauges on the dash started to go in opposite directions. For example, if fuel was 1/4 full, the gauge would show 3/4. Started tractor yesterday and gauges were showing wrong...

How to keep the water out of the transmission case . and Yes the tractor is out side Thank you:)

The right side power steering cylinder on my 1986 Ford 3910 tractor cracked along the long seam of the tube and leaks fluid. The cap from the reservoir was missing and I think water got in and froze. Can the cylinder tube be welded or rebuilt? The problem is that I can not get the rear (tie...

A fellow that rebuilds Ford tractors for a living is selling a 1983 Ford 3910 that he tells me came with the larger engine 4.4 (201 CIO) 55HP. He said that there was an overproduction of this larger engine that was intended for a backhoe that wasn't selling well and Ford put them in the 3910...

I'm looking at a 3910 I checked tractor data and seen that some of the 1986 and 87 had diff serial numbers can someone tell me why and thank you

Bought this tractor a couple months ago. Noticed it had a rear main seal leak, along with several others. After I got the front axle rebuilt and back under it I decided I'd tackle the rear main seal. I built a stand on wheels to fasten to the front half of the tractor. Already had the rear...

I'll pay a premium price for these if anyone has a set. Need full set of 5 and want the OEM style set. Thanks It's like this set.

Decided I am tired of oil drips on the shop floor so fixing some leaks. This tractor leaks out of the axle shaft seals which drips from the knuckles and it leaks out of the center section swivel. So I rigged up a stand to hold the tractor in place with the axle removed. Then strapped the axle...

Hi guys. My 3910 3pt linkage has been progressively getting worse at lifting weight. It seems to work fine with no weight but as soon as I try and lift a round bale, it can't lift it. It slowly got worse and worse until it won't lift it at all. I topped up the fluid so it's full and it didn't...

Decided I better build a front bumper before I take this tractor to the timber. Maybe it'll save the grill and fiberglass nose piece.... Built it all outta flat iron.

Little bigger chassis than I was looking for but couldn't resist. Original owner was a sod farmer. Bought it from second owner who took it in trade for some new sod equipment. 3000hrs. Needs rear tires, they are the originals. Otherwise seems solid. Time will tell.

I installed a new starter solenoid on my 3910 and now all it does is click. I checked the battery and it is hot. I rewired it the same as the old solenoid. The new solenoid and the old are the same. hot from battery to top post and wire from key to the male connector on top. Ground wire to...

How do I remove a starter on a Ford 3910 3 cylinder diesel tractor? It has hydraulics in the way for clear access to starter. I am trying to change the solenoid (the old one crumbled) and can't get center plunger of old one out. I figured I would have to take the starter out but can't get to...

The hydraulics on my 3910 will work perfectly when I start the tractor. I can raise the FEL all the way up and lower it all the way down, then immediately start raising it back up and it is noticeably slower. I can do this about 4-5 times, each time it gets slower with small jumping like surges...

I'm looking at a used ford 3910. One thing I noticed is that the clutch pedal engages in a pretty high position right before full up. Is this a sign of a lot of clutch wear or is that when it engages quickly coming from bottom up?

I have a 1986 Ford 3910 with the single pump hydraulic system. Currently the tractor has an open-centre FEL connected to the selector valve under the seat and has NO remotes. I want to add a single spool remote control valve to run some double-acting hydraulic actuators on some implements, for...

Hi folks, I joined this forum just for this problem. I have a ford 3910 with about 1,100 hours. Tractor is in pretty good shape for an '89 model. A couple of weeks ago, it wouldn't start. It has always fired right up. I bled fuel lines at filter and pump, worked the shutoff a few times, cranked...

Hi everyone, Geesehaven here. I'm new to the forum and exasperated with my Ford 3910 diesel right now. It is very cold here and my Ford 3910 turns over momentarily then quickly drains the battery and won't start. Tried to jump it but basically it didn't help. Battery is 9 years old so decided...

I just purchased a ford 3910 and am blown away by the way this relatively old tractor performs. The tractor had 1486 hrs when I purchased it. I have had it less than a week and have worked the fool out of it. It came with a Bush Hog 2446 QT FEL and has FWA. I initially purchased it for a small...

Hi All, Love the site so had to join. I bought a 1989 Ford 3910....a beauty. My problem is the 3 point lift. it lifts up ok with the transport box on...but after about 2 minute it drops of its own accord. Lever stays in position ....so i have to get back in the cab and push down...

Hi all. As usual I am always lookin out for a project. I thought I had a John Deere to add to the fleet but it didn't work out as the family argued about who was gonna get the money I told them just to for get it! Anyway...I bought my wife some swivel stools from a friend. On the way to pick...

When I mow/bushhog long grass, the grass winds itself around the driveshaft. It's a real pain to get off, and it breaks the seal where the shaft enters the rear half of the tractor. Is there something I can do to prevent the grass from winding up? Is there a guard I can purchase to prevent it?

My friend has a 3910. He has had it since new. He lent it out (may or may not have anything to do with it) and now when he is bushogging on hills sideways or when he hits heavier grass it (the bushhog) completely dies down. He changed the fluid and filter. Says it has enough fluid in fact blew a...

Good to be part of the forum. I have a ford 3910 with a Perkins 3 cyl. Diesel. I'm in the process of putting a new starter on. That's what brings me to the forum. I've been having trouble starting. My son took the solenoid apart and reassembled it. When I charged the battery and tried to start...

I am going crazy looking for a tractor with a loader. I am looking for a 40 to 60 hp machine that can run a 5 or 6 foot cutter and has a loader that can be used for lifting various items like concrete pipes, removing cactus, hauling dirt, etc. I found a Ford 3910 with a loader for 9,750 with...

we have 1988 Ford 3910 that mice chewed the wire from the fuel gauge to tank sender. On the back of the gauge cluster there is an open positive terminal at the fuel gauge and open terminal connected to wire going ground. I can't remember if the wire should've went the positive or ground...

I checked the power steering oil today and its low. Unfortunately my NH dealer is closed tomorrow. Is there another fluid that is a duplicate at Napa or autozone? The manual says i need M2c-41b or m2c-159-a or -b. Any ideas?

I own a Ford 3910 (built in 1989). It keeps blowing the high pressure seal that sits at the bottom of the steering shaft. I opened up the power steering pump and checked the relief valve and it seems to be working properly. I am wondering whether the system is producing too much pressure...

Our tractor at our non-profit horse park has over 3000 hours. The steering sector is broken and it required a quart of steering fluid in one day of use. Can not find the part. They do not make the part anymore. Anyone?

I have a Ford 3910 diesel 3 cyl tractor. I have been trying to get it to start. I have fuel at the filter and the pump but nothing at the injectors. Have blown air thru and no blockage battery is good and cranks well any body please help almost time to cut the hay.

I have a Ford 3910 and the injector pump leaks fuel from the back side. Can the pump have new gaskets installed or does the pumb have to be replaced or rebuilt? Does anyone know the costs for new gaskets or replacement? Thanks for your input.

I've been lurking on this site for a couple of months now and have learned quite a bit! I've been looking at Ford 3000's but found a Ford 3910 nearby that is for sale. I was wondering if y'all could help me determine a fair value for it. He is asking for $8500. Here are the details: 1985...

My 1988 Ford 3910 is equipped with a single spool remote control valve which is mounted below the tractor seat. Two hoses run from the valve to the rear of the tractor where I can attach two hydraulic hoses. The valve is operated with a single lever handle which has a detent at its center...

my Ford 3910 sat all summer with a new battery(spring 2011) & now it won't even start to turn over! Checked battery & it was holding 12.47 volts! It ran fine when I put it away! I'm lost!!!

Recently my 3910 does not want to go into gear when shifting from a forward gear to reverse, and vice versa. When I try to shift the gears don't want to mesh. At other times it will shift just fine. It seems like the transmission isn't slowing down enough to allow the shift. Is this a clutch...

I need some help locating the part number for a power steering fluid supply line on a 1989 Series II Ford 3910 4x4 tractor. It's the smaller of the two lines (not sure what the difference is between the two lines). I've tried looking through parts catalogs and images on the Internet (ytmag and...

Hi! I'm new here, please be gentle. A lady down the road is selling a Ford 3910 and I went to look at it today. The loader, pto, and rear hydraulics checked out, but I wasn't able to get in gear. I'm wondering if this is a tractor IQ test I'm failing, or if it's broken. There are two shift...

I bought a Ford 3910 a couple months ago and did not run it during the winter. It will not start but battery is good and turns over good. Fuel is OK out of the filter. I have heard that they can lose their prime. How do I fix that?

Hi Have had a Ford 8N and 9N tractor but no MF and not familiar with the 3910 other than I think that it pretty much has the same front end as the older N series tractors had. Have attached a couple of photos of one for sale that I might consider, wondering if someone would have some thoughts...

I bought my first tractor last June, a used Ford 3910. I have no documentation at all, but I've recently been told by a visitor to the farm that I needed to change the oil and air filter. Having never done this before, I figure I might need some help to make sure I do it right. I don't even...

I bought my first tractor 10 months ago, a used Ford 3910 diesel. I'm hoping to find some help with maintenance how-to, and any useful tips that anyone has that will help me keep this thing running smoothly for many years to come.

Looking for 5/16 press in grease zerks. None of the auto parts stores have them. The same with TSC, Harbor Freight and/or Northern Tools. Internet search did not work, kept coming up with junk. Does anybody know of a place to get them or should I just go to the New Holland dealer and bite...

One of my front wheel hub assembly grease zerk will not hold the grease in. The grease will come back out the zerk hole. I can see the sealing ball is missing. So I got to change out the zerk,,,but it is a push in type (press in). Not the type that you can screw out. Never had to replace...

Thats what Im trying to do. Im guessing a subframe is the way to go, but how? Backhoe is 1600lbs and base tractor is 4500lbs + FEL. I've included some photo attachments. Im looking for ideas. The tractors FEL presently provides a subframe, so tempted to try a 3pt setup first, but I know its not...

I have a 1989 Ford 3910 4-wheel drive tractor (my first tractor, by the way) that has been running fine for months, but recently while bush hogging has been dropping the bush hog down to the ground occasionally. It will lift it again for a while, then drops it again. Sometimes, but not always...

On the Ford 3910 do you need to keep the clutch tied down when not in use??? On all of my other tractors over the years I had too. But on my 3910 there is not a way to do so. The manual does not say anything about it. I use the tractor about once a week. The longest it sets is about two...

I know someone has an answer on this problem. I must be missing something small!! The auxiliary service control valve does not work on my Ford 3910. The three-point hitch works, but I cannot pull the A.S.C. valve out to the other two positions. Also, I cannot change the speed of the...

I posted this on the Hew Holland/Ford section, but no one had an answer. Zero response. The auxiliary service control valve does not work. The three-point hitch works, but I cannot pull the A.S.C. valve knob out (away from the tractor) to the other two positions. Also, I cannot change the...

Does anybody know what type/size/model/make of F.E.L. that will fit a Ford 3910. Also, what will the price of one will be, used and/or new. frankmako

The auxiliary service control valve does not work. The three-point hitch works, but I cannot pull the A.S.C. valve knob out to the other two positions. Also, I cannot change the speed of the three-point hitch. The valve knob is set to the 吐ast setting (a good thing). The switch/knob will...

The operator’s manual states, “the inner air filter should only be serviced by the dealer”. So what gives?? For the outer filter I just remove the wing nut and pull it out. The inner filter is held in by one nut. It looks like I can remove the nut and pull it out just like the outer...

The advice that I received was great, Thanks to those who replied. Had I not had a typo, I would be set on my decision. I pasted in my original message below with correction, the owner tractor that was in good condition has 5500 hours not 1500. I have to admit, I have no clue if that is...

I am about to be a first time tractor owner. I have narrowed my search to two ford 3910s. One id from an individual who says he knows the past 5 year history of the tractor, looks to be in great condition 1500 hrs, The second is from a garage (1800 hrs) that reconditions tractors and sells...

We just got 40 acres (1/2 woods, creek, 1/2 pasture). I was thinking about a new compact 4x4 tractor w/ loader, but a friend has a 1991 Ford 3910, 42 HP w/Loader, box blade, auger, with only 500 hours - it's in perfect shape, always stored covered - wants $13000. It seems like a good deal for...
