john deere wet clutch December 26, 2014 01:14PM
I got a 5 disc clutch that was slipping. Got it tore down an disc are worn on one side an not the other or more noticeable on one side. One disc is completely worn out on one side. Had trouble all year getting in gear while running. It is set up with welded hub an valve body modified. Any ideas?

are you using the special john deere tool to adjust clutch? Is one side off the plate machined more agressive than the other? another issue i found with mine if your using a 4430 there is a serial number split on adjusting them. check the casting number on the clutch operating housing to make sure if you have an early or late set up.if the casting #'s are R50301 or R62742 its a serial split 47851 and below. on the tool you would need JDE-78-4 & JDE-78-10 on the traction ring and JDE-78-3 & JDE-78-12 on the pto ring. casting number R62744 & R61397 are serial 47852 and above. tool would use JDE-78-4 on the traction ring, JDE-78-3 & JDE-78-12 on the pto ring. i had a 6 disk perma and every time i freshened the clutch up i always had issues getting the tractor in gear. i always had to bypass the neutral saftey switch and start it in gear. after about 3 passes then it would go into gear decent. those permas drag so bad. you can thank the oil drag for that.

You have to get a clutch housing off a late model 4020 or 4320. Those seem to work the best. Get new flywheel, clutch and transmission shaft. Will have to change return oil dump to top of tran cover. I am taking for granted, you have no 2 speed. We went though all the crap you are now. If we would have changed when other people told us to, we would have saved A LOT of money and time. The dry clutch simplified everything. Have ran it for 2 years without ANY trouble. 900+ HP. Atlas tractor can fix you right up.

Has any converted a wet clutch 4440 to a dry clutch and been able to keep and use the two speed?

Been all though this. Put in dry clutch and your troubles will be over.

Do you still have the pto shaff in tractor. I have seen several that leave pto in take the cutch and pto level weld together so that when clutch is fully depressed applies the pto brake and it stops the clutch so tractor can be shifted

Crower springer the way to go comes with new fly wheel fully adjustable for horse power load.Put a double disc springer in last winter pulled all season with no problems.New billet input shaft pto deleted,if you go less than 3 disc's you will need to make a throw out bearing bushing.Call Darren Rursch he will set you up not cheap 4200.00 for a 2 disc with new input shaft.

Every thing new fly wheel ,clutch,input shaft,pilot bearing,input shaft bearing and all new seals.you will have to split tractor at trans also to change input shaft out.Factory fly wheel and clutch housing are gone you will need to know how many bolts are connecting fly wheel to crank shaft and diameter of those bolts before ordering new set up.

I didn't start having problems with mine till I got up around 1000 hp. Half way through a seaon I had to replace discs on a 5 disc setup, never had trouble with the 2 speed. Nail in the coffin came when the high range pinion let loose wiping out the rest of the trans. Never messed with the wet clutch after that, ended up going to a 3 speed with a 4 disc crower springer, solved all the problems all at once and created a few other challanges that were easily overcome.

It will always be cheaper in the long run to build the tractor from the back forward. Most people do it the other way. Save yourself money, time, and grief and put in a Crower.
