1020 Clutch Replacement

[Gumbi]

I'm looking to replace the clutch in my '66 1020 Gas here pretty soon. I'm good with a wrench, but have never split a tractor before so this will be my first time. I have the shop manual, and will be looking to building me a set of splitting stands here in the next week or so. Tractor does have a dual clutch setup.

Few questions, where should I get my new clutch from other than Deere and what all should I be replacing while I have it split? Do I need to replace the pressure plate as well or just the two clutch plates? I will also be doing the rear main oil seal when I do this, it's leaking and is the reason why I need to do this repair. I already acquired the special seal installer tool to do this. Do I need to replace the release bearing cradle along with the bearing?

Does someone sell a kit with all needed parts?

Thank

Buy the full clutch kit from this site or other such place. I did one a few years back on a 1020 and there was something about having to line up the PTO clutch but don't remember what all it took to do so. I rebuilt the engine at the time. I do not use splitting stand I have an over head I-Beam with 5 chain hoist hanging on it and and 3 of them are on trolleys so splitting tractor is easy

I've done mine twice, although it's diesel. I would consider checking around and see if you have a shop within an hour or two's drive that can re-line your discs and rebuild your pressure plate. Also probably need to re-surface your flywheel as well, and they can do that at the same shop. As @old said, the two-stage clutches need to be kept in alignment when installing, and as I remember we had to have the shop do the aligning of the discs for us - I'd have to look at the manual to check but I do remember that being something more than just twisting wrenches. Also, need to replace the pilot bearing, and check the fit of the input shaft into the pilot. Mine was loose. We shimmed it at first, but I just replaced the input shaft when I rebuilt the engine this winter.

Wouldn't the clutch alignment tool take care of aligning the two clutches and the pressure plate? At least that is the way I understood it,
but like I said I've never done this. Open to all suggestions.

That clutch isn't available from Deere anymore. Hasn't been for several years. They'll have to get it for you from A&I. If it was me,I'd take the whole thing to Clutch Dynamics in Lansing Michigan and have them build new clutches,grind the flywheel and rebuild and set up the pressure plate,but if you're not in Michigan,I guess that could be a problem. Rolling one of those things back together and lining up the splines to both clutches can be enough to make a preacher swear.

Different parts are listed for the diesel so I don't know what yours is like, but for mine - No. They assembled the pressure plate and PTO clutch into a unit and pre-tensioned it to hold it in place. The shop was 1.5 hrs drive from home. They forgot to put the assembly down into the flywheel to keep it aligned. On the way home a bad bump or something must have jarred it pretty good and we found out on our first installation attempt it was not in line anymore. I can't remember the reason, but it wasn't something we could correct and we had to drive it all the way back to the shop again. If you can find a shop like that, that re-lines brakes and clutches, they can do all that for you. We took them the parts first thing in the morning, hung around town for a while, then picked them up all rebuilt before lunch. The second trip we put the assembly into the flywheel to keep it from getting out of line!

Unless there's something wrong with it, I don't see why you should need to replace the throwout bearing carrier, but definitely replace the bearing, and the pilot bearing as well.

The shop I use is in Birmingham, AL. I would think most areas have something similar within an hour or two.

Have you determined, for sure, that you have a "continuously driven PTO" vs. an "independent PTO" or "transmission-driven PTO?

Clutch systems are ENTIRELY different.

 

[old]

No you have to Aline the PTO clutch before you install the clutch pack on the flywheel

 

[matthies]

May sure you check the spline count on the old and new disks, ran into a clutch from deere that you had to buy a different disk as the kit came with the wrong count.

 

[Gumbi]

Yes, I mine has the continuous PTO option or a dual clutch setup.

So, looks like the PTO clutch for the gas engines AT20916 has been replaced by RE31382 and it looks like that one is listed for $600! which is nuts for a clutch disc. The drive clutch RE29882 is available and like you said is from A&I. I'm curious why there are different PTO clutch disc for Gas vs Diesel tractors. I was really hoping to purchase all the parts beforehand, but looks like I might be finding a clutch repair shop for relining them which I did find one near by.

"a clutch repair shop for relining them"

If the local shop knows what they are doing with a clutch like this it's by FAR your best bet.

They will have the equipment and specifications to resurface the flywheel and the individual pressure plates, check the springs for correct tension, and set up the clutch correctly with it bolted to the flywheel.

I'm curious how it's being determined that this pto clutch plate(RE31382) is from A&I & not JD. A lot of parts A&I supplies for JD have an "A" in frt of the part # similar to A-RE31382. I'm aware JD owns A&I but just curious how it can be determined the parts origin. Photo below shows spec's for your tractors pto clutch plate. I agree if RE31282 is only the pto clutch disk it's way overpriced.

I had the one for mine rebuilt for $75,same day service.

So, I'm not entirely sure it is from A&I. Normally I find the part numbers i need through Deere's parts catalog and then search it on
GreenPartStore.com to get a price. I've used them a bunch in the past when I can't make it to the local dealer any time soon, they're prices
are generally exactly the same as what I pay at my local dealer so I just assumed they were just another John deere dealer like anywhere
else. On their website it stated that RE29882 was a A&I product. The PTO plate did not specify origin.

I'm curious Tx Jim, how do you find the spec's for parts like that? I have looked in the past but never found where to see those.

Thanks

As I previously stated A&I parts usually have an "A-" prefix BUT not 100% of the time. A- prefix is shown on Green Parts page(A-RE29882) per photo below. I think Green Parts may be a division of a JD dealer known as AHW LLC Watseka, IL. 60970

To view parts spec's on JD parts site one needs to be signed in,then have part # entered in ones shopping cart. Left click mouse on part # & if spec's are available a window will appear with spec's/specification. Not all JD parts on parts site have spec's available for viewing.

If you have problem locating the part spec's feel free to email me.

All States tractor parts has the complete assemblies on Ebay. Ag Parts Ltd has complete assemblies as well. Study carefully as there are lots of choices as to how your tractor is set up. Tom

Just now finally got around to splitting the tractor last night. Was a bit nervous getting started, especially being the first time doing something like that. Anyways, findings and questions:

I cannot tell positively if trans oil is seeping out between the two clutch shafts, but there was easily a cup of oil inside the clutch housing. Something else I found is that the clutch shaft (the inner one) has a lot of play in it. I can slide it in and out 1/4" and it wiggles up and down a good 1/8" fully within the PTO shaft. Is this normal movement? You can even tell that the clutch shaft had worn a fairly good dimple into the crank flange inside the pilot bearing. If this is not normal, what needs to be fixed and how do I go about it. Judging by some other post I have seen online I need to pull the clutch housing to get to the seal/bearings for the clutch shaft?

Something tells me that this is not normal and I am in for doing a double split.

Any advice is greatly appreciated. Thanks!
