john deere 400

The throttle has been getting stuck at idle. Not sure exactly how the governor functions in relation to the linkage but for a while I couldn’t throttle up from the handle but if you moved the linkage at the injection pump it would be fine for a few days and then it would get stuck again. The...

hello im new here i have a john deere jd400 backhoe i need info. on the motor plate # m53tw serial# 173253T i need to know what motor and yr ... thanks guys i need a major motor rebuild kit. and can i get one that needs to be over bore

Jd400 Pump started to whine while using the backhoe. Figured Id try do full service before I burn up the pump if I havent already. In the oil filter housing was a valve that doesn't appear to me to belong there. I have service manual and part diagrams but both show filter housing different...

Jd400 recently put in new seal kit in the steering wheel body because it was leaking at the top and it was working good, no issues other than chasing leaks, first in the nylon return line then side cover with the bushing below steering wheel. Yesterday the left tire went up slight incline...

Can i cap off the hydraulic inlet line at the steering wheel base. I have a seal kit ordered but I'd like to use tractor as I just got it.

The JD 400 Owner's Manual (1975-1983) recommends 85+ octane fuel but NO high-test gasoline. Thinking out loud that 87 octane with ethanol might not be good for seals, would 91 octane (no ethanol) be okay to use even though I consider 91 octane a high-test gasoline? -bob

Greetings; This has been also posted on other tractor forums. I just purchased an old and well used JD400 loader/backhoe. Lots of things to fix but I'll tackle one at a time. Fuel pump leaks almost as much fuel as the engine burns (it seems anyway). Got to wait for the pressure washer before...

I want to take the backhoe off of my 1969 JD400. According to the manual that I have there should be a dead end block to plug in the main hoses and the plugs from the block are then used to plug the loader sockets.There doesn't seem to be a dead end block on this machine and I'm guessing that it...

Hello I have two JD400 backhoes one I’ve had for almost 3 years and one I just bought hopefully to make 1 really good machine out of two. Neither Is running, both are having injection pump issues . Firstly I’m having a hard time removing the pumps both are CDC type which I’m learning are the red...

Jd 400 w/ bachoe the right rear tire is rubbing the frame on the bachoe and fender,left rear wheel is about 1 " off the bachoe frame and fender ?

G'day, wondering if anyone has experience with this relic. I have used this old girl for over a decade, borrowed from neighbour. Backing up I noticed a bolt and large 1/2 inch thick washer had was lying on the dirt. Found where it comes from, on the left side just under the battery. The bolt...

FEL and attachments included. I would grab it but that would not leave enough ready cash for a Hotel when she kicks me out...

Hi. I just got my first tractor. And i'm pretty new to this. I have a John deere 400 1980. I'm trying to find a new snow plow . Do anyone know where I can find informations on what fit on it. I cant confirm it but it look like the front attachment that fit on the 400 also fit on the...

I have a John Deere 400 Industrial that has been working fine until one day it decided to suddenly blow out much of the hydraulic fluid, apparently past the hydraulic filter o-ring/gasket at the top of filter housing. I cleaned the screen and put in a new filter. O ring looked fine so I...

Just wondering what coolant most people run in these old machines. Keep in mind I am in Australia where antifreeze isn't important it's mainly corrosion prevention. Thanks.

Hi all anyone have a rebuild write up on these. They are on a 1968 JD400 backhoe. Thanks.

Hi all I recently purchased this jd400 and was wondering if you had to add fluid or if it's meant to pump from the mains to this header tank. will try and download a manual today to also assist me thanks for your help everybody.

Hi, The really great JD935 I inquired here about didn't work out. The owner stopped communicating after I looked at it, made the deal to get it delivered. I think he realized what it was going to cost him to get the tractor he wanted to replace it with! Wasted 3 weeks of my time, grass and weeds...

so i bought this poor old machine and i know absolutley nothing about it . i have no idea on its age or any of its controls its hard to start looking till i know what i i have there seems to be multiple gearbox options as well so any advice out there

I took the old girl down the road today and that was a scary ride! I have noticed the there is play in the wheel but man its a lot worse than i had expected. So when i got home i was looking at it and when i turn the steering wheel right the whole steering wheel turns up and that is about 3/4 of...

My John Deere 400 tractor wants to spit, sputter and backfires when under a load. Took the carburetor off and clean it and it started doing it again. Would a weak battery do it? or and bad needle and set in the carburetor do it?

After having the starter rebuilt, replacing the ignition switch and then the 20amp breaker, I finally got my tractor running, only to discover diesel fuel hemorrhaging out from the engine. I pulled the cover off and found it was from the area where diesel return line hooks on. The black rubber...

I have a 1970 JD 400 industrial loader with a backhoe. Let me just say this. I dont know a thing about hydraulics so bear with me because probably somethings that you guys say is probably over my head. At some point someone put a thumb on it with a lever valve that is plumbed in with the curl...

Hi all. I have a 1970 JD 400 loader backhoe. I would like to enclose it. Has anyone made a cab for one of these before?

Hi. I am new here. I just got a new to me JD 400. All in all it seems to be a decent machine. I am having trouble with the fuel gauge. It always says full. I found that the wire going to the tank wasn't there so I fixed that. But the gauge still doesn't change it always says full. How do I know...

Several problems with throttle. It was sticking. Wouldn't shut off. Screw at rack and pinion gear / lever broke off. Unable to find source for parts. Should the sleeve, valve, idle adjusting screws be removed and cleaned, o-rings replaced, etc. Any guidance appreciated

This JD400 seems to be manufactured in Germany but since itｴs from -68 I expect that not a single thread is metric. Living in Europe I have a multitude of metric tools but a very limited set of large SAE (inch) wrenhes and sockets. The service manuals state that the following larger (> 1/2")...

My old JD 400 backhoe/loader stopped running and was not getting any fuel to the engine. I removed the electric fuel shut off solenoid and it was dead -- no movement of the valve to let fuel in. I checked the solenoid with an ohm meter and it is open. No fuel to the engine. I jammed a piece...

My old JD 400 back hoe/loader stopped running yesterday because of no fuel getting into the carb. The electric solenoid fuel shut off valve that sticks out of the bottom of the carb was dead and would not let fuel pass. I stuck a piece of wire into the valve to hold it open so I could run the...

My unit is running out of hydraulic oil in the implements, with violent shuddering and then no movement either end. I have got it working for a few minutes by filling the header tank situated over the main pump, enabling me to get it back home. Since then I have replaced the transmission filter...

I have an old JD400 yellow version, has a front end loader and backhoe attachment. for years it has been slow to go into forward, well, it sat longer than usual, like 8 months, had no forward, none, nada. so, I pulled the screen and replaced the filters new hyd oil, still no forward, I raised...

This unit is causing me much grief! I fill the header tank above the pump, and everything works for a short spell, but then it pumps this oil into the transmission, thus overfilling it. I have replaced the hydraulic filter and removed the valve and spring that seems to isolate the oil flow...

I feel confident I can take the cylinder off the tractor. I assume there is some type of seal or gasket that needs to be replaced. Since it is hydraulics, and not specific to the tractor, are there shops that would do the work of dismantling and replacing the worn parts? Or should I be looking...

I posted about my starter issues last winter. This summer it started fine. I read that could be a sign that the starter is going (cold weather problems, warm weather is fine). I found a shop that will rebuild starters, so I decided to bite the bullet before winter hits again and take the...

Hello, I recently bought a 1969 JD 400 with a Diesel engine. The engine oil is black as night. What oil should I use for an oil change? The book says JD torq-gard. Above 32 F to use SAE 30. -10 to 32 F to use 10W20. This isn't my first rodeo and I know oils have changed a bit in the last...

My first ever thread! My JD 400 has a CAV distributor type injector pump which I dismantled because of a lack of power, as it had sat for some time in the past with water in it, but still ran. When apart (and this is a simple job, contrary to what I was led to believe] I found that the governor...

I have a John Deere 1969 JD400. I've had it for about 4 years and I seem to spend as much time figuring out repairs and working on it, as I do using it. It's a beast through, and never fails to do what I need her to. I've had issues starting her in the past, usually in the winter. Slow...

Hi, I have a older John Deere 400 loader/back hoe, my question is do you have the tractor running or shut off when checking the fluid level. Thanks.

Hello, I've gone and worked a trade for a 1967 John Deere 400 backhoe. It's diesel and the story is that it hasn't been run in 5 or 6 years. It's been outside under a tarp, so it isn't in horrible condition. The wiring leaves a lot to be desired and as soon as I can get it running and trailer it...

Hi.. I'm a mechanic, not a tractor mechanic so bear with me. I've been working on an old JD400 with a backhoe on it.. we've repaired leaks (fuel and hydraulics) and even put a new hydraulic pump on it (had no power).. everything was straight up and I encountered no problems.. lots of power...

I am working on a 400 for a friend that was not running, right after I got it running the 3 point would raise and lower (I never tried to move forward or reverse) and now it will not do anything. No hydraulic pressure at all. I ended up pulling the hydro filter off because it was damage, and...

I have a JD 400 built in 1966 and it has run fine until lately. The JD dealer has cleaned the sludge screen filter and installed all new filters in the hydraulic lines. The dealer thought the machine was running correctly when I picked it up but when I tried the hoe and the bucket the pulsating...

I have a 400 that after using it for a period, will not restart if i shut it down for a short time. The gas tank cap seems to be ok and the pump is running normal but i have to wait till it cools down to try it and it will fire right up. Any help would be appreciated.

Aloha! Newbie to TBN. I am having a problem with hydraulic fluid not returning to my main hydraulic pump. I rebuilt the main pump, so it is working. I am not sure if the problem is my transmission pump, a clogged screen (inlet screen?), or a valve that is stuck. The tractor was operating...

Hi everybody, I bought a 1970 John Deere 400 loader backhoe back in Oct/2010. I've got around 2 3/4 acres I'm clearing, filling and digging. I'm looking forward to learning everything I can from all of you. Thanks

I just bought this fine machine, and within days it sprung a leak in an oil line. In the process of replacing leaking section of the metal oil line with a hose and clamps, I must have jiggled the connection because when I started it back up, it was leaking from the connection with the reverser...

I got a used 47" sb off craigslist and was told it would connect to a 400 and 425. The dealer says a sb that connects to a 425 will also connect to a 2305, but I'm having trouble finding an adapter. I've attached two pictures of the sb and the mounting kit that came with it (had to remove it to...

I'm a total newbie here, but in searching, I haven't found many specifics on the JD400. I've been lurking on Craigslist for some time waiting for a good John Deere garden tractor to pop up. A JD400 popped up for $1500 firm. It appears to have the 3pt hitch (I assume it does not have the rear...

There I was, mowing merrily along this morning. I heard a thump (lots of pieces of limbs and drbris still in the grass from Hurricane Ivan) down by the 400 deck, and the mowing stopped. Normally, that's a sign of a broken belt, or belt that's jumped off one or more pulleys. I wasn't mowing...
