Is the small plastic line connected to the top of the steering pump? Make sure it is there and not kinked somewhere restricting flow of oil. Oil needs to have free flow back to sump through this line or it can cause seal to blow out. Also try unhooking that line and hook a small hose to it and...

With 0 volts to starter when key is turned to start, that means you still have a bad connection, or a bad cable. If you have jumper cables, try connecting one of the cables from positive battery terminal to big post on starter. See if anything improves. If so, then positive cable is bad. If no...

1966 Rowcrop 4020 with LP Gas engine.

Most likely electrical/electronic issue. Do you know how to read codes? Error codes should be stored that will help pinpoint problem. under left cowling cover is the fuse panel. Depending on your serial number, there is either a diagnostic switch that needs to be activated or a diagnostic fuse...

Diesel fuel from 1972 was a totally different product than the ultra low sulfur fuel of today. The older fuel was much more stable and had longer shelf life.

I will start out by saying Al engines have their own “normal “ operating characteristics. Some smoke more than others and some have higher or lower oil pressures that are considered normal. I am a JD tech, so not familiar with your model Ford. The slobbering and smoke on this one may be unburnt...

If the decal is correct for shift pattern, it has the TSS transmission. The collar shift had 3 & 4 reversed from what this decal is showing. The steering wheel emblem is newer than the tractor. that style was used after year 2000. I am sure it was replaced at some point. Many of them cracked and...

Make sure link #2 pivots freely on shaft #5. I have seen some of these get rusty and need to be freed up to work properly. It relies on spring pressure to move and if too tight to pivot, spring can't move it.

If it is a cab tractor, the cowl is held on with clips that just snap apart. Pull straight out on sides near windshield to pop clips loose. Then pull back towards the seat to unseat other clips. If open station, there are like 6 or 8 bolts to remove. Raise hood to access some of them. The knob...

It looks to me as if the mounting frame parts are all available though parts department. The are Quite expensive because each part is ordered individually instead of the complete bundle that was originally available through sales dept. My guess is around $5000 for left and right frames with...

Tech manual showed depressing tabs to remove. Have seen other models that way. Definitely not the first time the manual has led me astray. Does seem odd to rely on friction fit to hold it on.

There are plastic tabs under the tank that need to be depressed to release tank. Then it slides off. Still will be a little snug to release the seal of the orings. Most likely the orings are the source of the leak.

I was wondering if original poster could get a picture of the pipe found in shifter. Might help to identify it. If there is internal leakage due to misplaced or broken pipe, it would help explain the jerky hitch.

Will John Deere corn head grease work? It is softer than the Ty6341 polyurea and is also a polyurea thickened grease. Part number is AN102562. Not sure of availability at deere but Amazon shows case of 10 for $84.71

Have you checked ignition timing with a timing light? Should be at TDC at idle and 28 degrees advanced at wide open throttle.

Most likely the regulator is bad, but also check out the glow plug circuits. Have seen a few of those have a glow plug relay stick on and cause glow plugs to stay on all the tie. This over works the low amp charging system and causes failures. Hate to see you have repeat regulator failure due to...

These symptoms sounds as if the engine suffered what is called four corner seize. It could have temporarily seized the piston to liner. if so, it will likely happen again. Seems like there is a lot of unburnt gasses in crankcase to cause explosion in crankcase and blow out dipstick. Maay need an...

Sounds good. Hope they treated you right on the bill. Also hope the techs that came in to do it right, trained the other techs as well.

Your pump needs the T22915. T22914 is for smaller pump with keyed shaft. Yours has a splined shaft. Shaft is most likely worn also and should be replaced if you want coupler to not fail prematurely.

Well I have to admit, being a JD tech since well before the 5E series was ever built, I never saw a filter in that position before. I checked parts catalog and tech manuals and sure enough I see it does exist on some tier 3 emission models. I then checked 3 different versions of owners manuals...

I have done just that on a few occasions. On problem machines that freeze up over and over, I have drilled a small hole in the bottom of that cover to keep it dry. Better than thawing it out with heat gun every time it freezes. It seems that condensation collects in there even when boots are...

I suspect the reverser lever assembly is bad. TInside the lever assembly are 4 switches. Forward switch, Reverse switch. Neutral switch and a not-neutral switch. codes are indicating problems with the neutral switch and not neutral switch in lever. Since you had to jump neutral switch in valve...

I see from your photo that there is no loader mounting frames on it. WHen did the loader get removed? Was it before you originally took delivery? If so, my guess would be that the dealer didn't connect hydraulic lines properly or maybe didn't remove an internal pipe plug when loader valve and...

General rule of thumb for normal operating temp of tractor hydraulic systems is 100 degrees farenheit above ambient temperature. I don't like seeing over 200f in the most extreme conditions. You mentioned a 6 foot bush hog. WHat is the weight of the mower? Does tractor lift it with ease or does...

Here is a listing of individual parts for power beyond. Hope it helps.

Are you sure of the dtac solution number? I did a search and that number doesn’t seem to exist. It is possible Deere removed it if they thought it was no longer a good solution. Have you checked steering and hydraulic pressures? Also look at all hydraulic lines to see if there are any lines...

PTR 524234.04 is for transmission enable pressure sensor voltage low. PTR 3509.04 is all transmission sensor voltage low. This is the same for CCU 3509.04. PTR 191.17 is for transmission top shaft speed is too low. PTR 522456.31 is for shifting without clutch, I wouldn’t worry with that code...

Check to be sure brakes aren’t dragging. Does it coast easily in neutral on slight incline? Problem will not be dry clutch mounted in flywheel. On power reverser, that clutch is for pto only. Does it make noise in forward and reverse?

The lower left coupler appears to be missing some of the balls that hold the hose tip in. Suggest not using that left set of couplers. Open the dust covers on the other couplers and inspect for dirt or other problems. Hoses should just push in and lock in place. The knobs on top of valves adjust...

If the problem is with the mower control valve, the tractor manual won’t help. If you can provide mower make and model, as well as what problem you are having, maybe someone can help.

https://www.agexpress.com/repair-services/ This is a great place to have almost anything ag related electronic devices repaired.

That is an improved design seal. If you buy from John Deere, it is the only choice available. Other suppliers may be able to furnish original style seal if you can’t obtain the proper tool to install it. On your earlier question about timing, when crankshaft is at TDC, there is a hole in...

Most 5 series loaders come from the factory with the JDQA brackets. They are removed to install SSQA brackets. They are attached with a couple of pins. There are probably some stock JDQA brackets laying around that could be bought cheap at dealers or on farms. Depending on how old of model the...

Can you also provide close up photo of the valve housing surface where the cover bolts on? R49187 is the correct seal number

That is intended for diagnostic testing only. You can measure system relief pressure there. There is no function of it mentioned in owners manual.

First, the check valve missing will cause no problem other than oil draining back and possibly causing hesitation of hydraulic function on start up. I have seen many missing ones over the years. It is easy to have one fallout when splitting the tractor and it falls out of the line. Second, it...

Yes, replace couplers only. I would go ahead and change all of them. The new replacements are now different and causes problems if at least a pair is changed at once. The new ones are now improved and have eliminated the drain hoses closest to valve block.

Everything you have said screams that a battery cable or connection is bad. A perfectly good looking cable can be bad. You mentioned bypassing the negative cable with a jumper cable. Try doing the same thing with at the positive cable . Connect one end to the positive battery terminal and the...

You need to check the wires to the solenoid under the tractor. The switch sends 12 volts to the solenoid when in 2wd. The solenoid opens and lets transmission pressure into the mows clutch to disengage it. If there is 12 volts to the solenoid when in 2wd, then you need to check pressure on the...

Yes it can be split that way. I am afraid you will not be successful pulling the crank from the bottom. I don’t think the timing cover can be removed without separating the front support from the engine block. When you already have to split it to remove flywheel and flywheel housing, engine will...

I would test the red #672 wire. It is the same wire that starts at fuse F6 or F12 depending on your serial number and it feeds the enable pressure switch, enable relay, not neutral relay, park switch and rcu. There are splices in the harness that could possibly get corrosion or lose contact. If...

This kit should be all you need to connect the lever and cable to the existing valve spool on your tractor. It also includes the 2 hoses, couplers and coupler bracket. Here are the instructions.

I agree that the T17882 packing is blown out, as well as mounting gasket T21641. You can try looking in the fill hole with hitch up and down both, although since the T17882 is blown, it is probably spraying inside also which will make it difficult to tell if spraying oil is coming from blown...

I agree with AR. Curious about the dark line on the block above the spark plug and extending back. Is that a crack?

Hot oil can be caused by defective air pump inside of the transmission pump. There is a plunger, piston, spring, ball and guide that builds air pressure in the front cover area to keep oil pushed back in transmission. If oil level gets too high in that front housing, the oil churns too much and...

Is the lever next to your right leg in gear? It is a high low range lever, but there is a neutral in the middle of high and low. If that is in a gear, then my next guess would be you may have a broken bolt on the hydro drive gear. Hydro needs to be removed to repair, but a fairly simple fix...

The later tractors used a signal from the alternator to operate the tachometer. Dark green wire #325 goes from alternator to tach.

Sounds like either low pressure or a worn out clutch. You can check the pressure with a 300 psi gauge and a 1/8" male pipe adapter. Pressure should be around 218 psi. If low, you can check orings on solenoid, or possibly defective solenoid. If solenoid and orings are good, then cliutch needs to...

Check your hydraulic couplers. One is probably not seated properly.

No one has mentioned fuses. Have you looked at them? Do gauges or warning lights on instrument panel come on when key is turned on? If fuse is blown, you may have the cold start sensor shorted out.

Standard sizes are still available from Deere. Undersizes are not.

I assume it is the relay module. It is a little brain box of sorts. It gives a couple of seconds of delay if you bounce off the seat before pto shuts off, also controls the RIO circuit and allows rear pto operation without being in seat as long as operator satisfies all requirements to engage...

Hard to believe an injector at 1800 hours but anything is possible. I assume he has done all the basics such as checking all rubber fuel lines for dry rot cracks that can cause air to be drawn in system? Also check that they aren't pinched or kinked anywhere. If tank screen is clean and filters...

Gear lever is park lever.

There should be 4 wires to terminal 15. One should be a black wire that goes to the switch for thermostart. One should be a black wire going to ground the alternator light and air filter indicator light. One should be a black wire to start safety switch. Other one should be a black wire going to...

I would like to apologize to everyone that has sent me private messages in the past. I never saw that I had any messages until this update and now I see I missed quite a few. I will try to do better going forward.

Parts breakdown shows the shaft is a separate part but is no longer supplied as a separate part. It substitutes to a complete gearbox. It appears if you remove the bearings, there is a snap ring behind one of the bearings holding the gear on. Shaft has a woodruff keyway cut into it to drive the...

Some models would display error codes in display. What lights are coming on? DOes anything seem to be malfunctioning when lights are lit? I am attaching a pic of dash. Area "D" is where codes may be displayed if it is equipped that way. If not equipped, then only way to read codes is for dealer...

Ohio, Just wanted to add a couple of things. First, at cranking speed you won't see a gallon or gallon and a half flow from filter housing. Should be close to that at 1000 rpm running. Second, have you looked at the filter relief valve? That is behind the 1 1/4" plug just above the filter cup...

If everything is functioning normally, I would suspect a bad pump coupler. Item 2 is a rubber coupler between drive discs that can wear out. Can also have loose splines in driveshaft #4.

Sounds like you have some binding linkage or a cable. I would start by disconnecting linkage from the reverser valve assembly under front of transmission. With linkage unhooked, see if lever on valve moves freely by hand. If so, then move back to rear of that linkage. It connects to a lever /...

My first guess would be possible engine oil cooler leak. Could be a head gasket or cylinder liner also. Is there any sign of coolant in the oil? I would recommend removing the oil cooler and having it pressure tested.

I think your serial number may actually be M00261X556096. That would make it a model 261. Tat serial number would make it a 1987 model year. Does it look like this one?

You need to replace seal #8. To to this, you need to remove cover #1 from the right side of the clutch housing. Then remove bolt and retainer #15 and 6. That will allow pin #4 to pulled out of steering shaft #7. Then wind the steering wheel full right to disengage the steering valve link from...

The hose you loosened is a low pressure line. It carries fluid from the transmission pump to the main pump. If you have pressure in that line, you should have sufficient oil being supplied to the main pump to function. If the small reservoir above the pump is full, the transmission pump is...

Since you mention the differential lock valve is hard to push, I suspect maybe something inside the valve is not assembled properly or the linkage going to brake pedals may be binding.

I don't want to get between you two bantering back and forth, BUT, I think this is the valve buickanddeere was referring to. It is the pressure control valve for the hi-lo adn independent pto. And yes the pump does have to build between 140 and 160 psi to supply engagement pressure for these...

The plug I was referring to is #2 in this diagram. The one TxJim mentioned will work as well, but it may be more difficult to access with cab. Plug #2 is also the plug to remove to access the parking brake adjustment. If you choose that one, you might want to adjust the park brake while the plug...

The pressure is adjusted with shims #34. Have you checked pressure on clutch while it is turned off? Does it go to zero?

Check the red 122 wire on back of light switch for power. THat is where it gets power from fuse. When the turn signals are on, power can backfeed through turn signal switch to lights switch on wire 102.

I had forgotten there is a screen on clutch housing on the 770. On the 870, 970, and 1070 I have adjusted The pto though the holes in the clutch housing. I am attaching the picture of the adjusting screws. If you can see theses screws (3 of them) through the hole and can get wrenches on them to...

If you have no stop screws, then they are missing. Should be 2- 3/8" x 1 1/2" bolts and jam nuts. There should be threaded holes in the valve body. I am attaching a picture of the screws on a cab tractor valve, open station is similar. bolt and nut is #10 and 11.

Here is the main wiring harness.

The 650 and 750 did not have the adjustable anchor post. That was on the 850, 950, and 1050. To replace the shoes, simply disconnect the linkage at the brake housing, then remove the six bolts holding the brake assembly on. then remove the housing and replace shoes.

On the bottom of the dash, there is a spring that holds the lever in the engaged position. Your spring is probably broken or missing. Order item #24 in diagram.

You may have a sheared pin in the clutch linkage. Under the tractor there is a shaft that connects the clutch pedal linkage on the left side of the tractor to the clutch valve on the right side of the tractor. In the diagram, #12 is the shaft that runs across from the left to the right. ITem #10...

It is possible the filter is clogged. I doubt that it would clog that quickly though. Usually filter will cause loss of power and gradual shut down if not changed. More likely a problem with the fuel shut-off solenoid circuit. Solenoid (#11) moves the linkage on the injection pump to make it...

Here is the breakdown. there are upper and lower blocks on each side. Page Name: SWAY BLOCKS AND SUPPORTS key PART NO. PART NAME QTY SERIAL NO. 7220 7320 REMARKS 1 L100866 Sway Block 1 X X RH L100865 Sway Block 1 X X LH 2 L100868 Sway Block 1 X X RH L100867 Sway Block 1 X X LH 3 19M7396...

Do you have a lever like this between the transmission shift levers? If so, then pushing in the clutch has no effect on pto. Push down on this lever to disengage pto clutch. The lever on the left side of transmission beside your left foot disengages the splines on the shaft. The lever between...

You could have an independent pto option. That would be a single stage clutch for the foot clutch with a separate clutch for the pto. Do you have a lever between the two shift levers? If you have a lever like this, lifting up on the lever engages pto clutch and pushing it down disengages it.

Looks like #14 in diagram. It is the brake pressure line coming off the steering valve.. Part number AR32238. They are still available. I assume it took a 7/16" wrench? The lower fitting is easier to tighten if you have a 7/16" crow foot wrench with a 6" extension.

Parts are available for the filter assembly. Seal kit is RE516553, primer pump kit is RE515404.

The transmission pressure regulating valve is located in the shift cover housing. Check items #25 - 29. Shims are used at #27 to adjust the pressure. This valve is only used when you have an independent pto or hi-lo. A reverser has a regulating valve in the reverser control valve. If there is no...

My guess would be a sheared roll pin inside the shift cover. Could also be a broken shifter or shift lever, but not as likely. Remove the cover and check pins #10 and #26. It uses a double pin with one driven inside the other.

The best way to tell if the brake valve is ok, is to cap off the lines coming out to the brakes. With the lines capped off, the pedal should be rock hard. If pedal is still spongy, then rebuild the valve. Replace check valves #9 and balls #15, plus all the orings and seals.

Here is another picture of starter wiring on 3020.

The circuit breakers at the starter were not original equipment. They were an add on kit that was provided when wiring harness was replaced. Without the breakers, there was no protection in case wiring or starter shorted out. Many of the original 24 volt systems burnt up the wiring until the...

Most likely problem is a sheared pin #19. Or a broken lever #15 or broken pawl #14.

TxJim, assuming the filter restriction switch and light are working, the filter is probably OK. The Trans pressure sensors are noted for failing occasionally, especially the original style. It is a good idea to replace the filter first to be sure, but I am betting on a bad sensor. It would be...

The liners/sleeves get pretty tight from rust and deposits over the years. I assume you have removed piston and rod assemblies. There are sleeve pullers made for the purpose of removing the sleeves. They are the best and safest way of removing the liners without damage to the block. With that...

The screen is under the left side of the transmission. Remove cover #17 to access.

There are orings where lines slide in. I am assuming you have earlier style like diagram. Later style did not have oil lines, only coolant. Part number is T13119.

Here is a breakdown. Where is your leak?

That does appear to be correct for the gearbox. From what I can see, it does not include the linkage. Items 10, 11 and 40 come as assemblies, but the rest would need to be ordered individually. This could be pricey as well. The linkage seems complex to operate a pto, but the mid pto has a brake...

First, you need to be sure the brake pedals or the brake valve is not sticking and not allowing brakes to release. If that seems ok, then jack up the tractor and see if the wheel spins free. If it is dragging, loosen the bleed screw and see if it frees up. If it still drags with the bleed screw...

Is the bushing 1/2" inside diameter or outside? If outside diameter, I am guessing #15 in park linkage. If inside diameter, I am guessing you have the park pawl version #28. It has a roller built into it. If you remove the cover on the right side of the transmission, you might be able to see...

I agree, lower that pressure down to 2350 and check the clamps on the lines. The trans pump pressure can be checked at plug on the right side of the shift cover. That is the port for the pressure for the Hi-Lo. The loader stuttering at times might be due to running the loader off of the rear...

Yes the pressure control valve can come apart. You will want to get orings #11, 12, 13, 15, and 20 to reassemble.

Look under the left footrest and find the turnbuckle for free travel adjustment. You most likely need to shorten the rod until you get an inch of free travel. If you already hve free travel, then it is time for a new clutch.

I don't have any experience with aftermarket filters. I was looking at the diagram for fuel hoses on your tractor. It is somewhat different than our North American tractors but similar. Are your fuel lines like this? I see several connections that could be source of leak. Besides the obvious...

I assume you have shifted mid and rear lever and that lever feels normal. If you grab pto shaft by hand, does it turn freely or is it tight? I am attaching parts diagram of the pto valve and lever. I asume lever #14 is what you are seeing move when you engage pto. It turns lever #29 and moves...

The 6900 is a little different than the US versions. On some of our models, we have seen water get into the transmission from the breather. I'll post a picture to show the breather. Old breather #8 & 9, new breather and extension #13, 14, 15. An extension can be added to raise the breather so...

See if this is what you need.

Those fittings are for connecting independent lift cylinder for the mid mower. You can then use the joystick to lift the mower instead of the three point lever.

Ever since I got a new computer last year, I haven't been able to view posts using internet explorer. I can log in and view lists of posts in different topics, but when I click on a post, I get a blank page. I am using Internet Explorer 6. I tried upgrading to 7 without any improvement so I...
