Mahindra 2525 Clutch Adjustment

[Harry in Ky]

More importantly, does the PTO shaft stop when you push the clutch pedal all the way down? That's what's critical here. Just because the shaft spins doesn't mean the clutch is working right.

ok, I see. if I remember correctly it does not stop spinning when I push the clutch. Im working on it tomorrow evening. I'll report back with for sure answers tomorrow. Thanks again. I appreciate your time.

"PTO works like it should". Just what does that mean? If you actually tested it or are you just guessing it works? As for the transmission portion, you can adjust to reduce free play to near nothing and test it again, If it still won't stop the shafts turning with pedal fully depressed (actually the transmission clutch SHOULD stop with pedal at half way down) then something is wrong inside and you will need to open it up and look at things again.

Harry, Im back. and I have a lot more info about my situation. Once again im very grateful for the experience and knowledge you possess helping me through this.

first question I have is.... Have you ever done a dual clutch without an alignment tool for that specific model. If not how did you align it and what did you use?

2nd,.....We now know, that when the the clutch pedal is fully depressed, the PTO does not disengage, even though the PTO clutch disk is moving freely. It can be seen through the inspection plate there's a nickels width between the Pressure plate and the PTO disk when clutch pedal is fully depressed(it can be wiggled with a screw driver) and PTO stays in gear.

during this we have the clutch adjusted so both plates will release at the same time.

there are no weird noises coming from the tractor, engine or clutch while it is running both with pedal engaged and disenguaged.

we did the tree test, the floating one wheel, apply the break test, drive figure 8 test etc.....to try and break a disc clean from sticking........nothing changes.

Rabbit gears are more difficult to get into.

This is our 2nd attempt putting it together and are certain that the clutch is assembled properly. we have a second clutch from the same tractor to verify with.

These are the best notes I have from what we gathered from our attempts to make it work today.

"PTO stays in gear". Assuming that means with pedal down and you're watching the PTO clutch disc through said opening. Someone tries to turn the shaft on the back of the tractor it won't turn unless the flywheel and engine turn with it? Even though you can see the disc floating free between the plates. And you have a similar problem with the transmission portion? That's more than an adjustment problem. I can't tell you from here just what's wrong but you need to split it back apart for sure. How many times have you split it so far?

I'm not familiar with the clutch in your specific model, but I've replaced hundreds of clutches in many makes of tractors. I don't always have a pilot shaft available and have gotten pretty good at "eyeballing" the hub through the hole while tightening the pressure plate bolts gradually until the plate to be centered is snug enough to stay in one place. Then shift it around with a long screwdriver until it's where I think it should be before fully tightening the bolts. Have done it that way for years with good success.

In this case not having seen what you did with/to the clutch while apart, nor what you may have done while rolling it together I really can't say what went wrong, only that you're going to get to try it again. I have my own preferred method of assembling tractors when I split one. I pull them together with a cable come along. I use rolling stands that are adjustable for height and both halves of the tractor are on crazy wheels so each can be shifted sideways if needed as well as adjusted up and down for alignment while pulling it together. No blocks, or floor jacks. That works best for me since I mostly work by myself, and I don't have much problem pulling them together without damaging anything. This week it was a Kubota M6040. I got it rolled together and bolted up yesterday afternoon, and will probably have it running tomorrow. It's an hour's drive away and I didn't feel like working on it today.

Thanks Harry, this will be the 3rd time we split it. first was to replace the clutch plates initially, put it together had this same issues were having now. 2nd was to double and triple check that the clutch was assembled correctly, put it together and have same issues. So now for the 3rd.............

We are doing the floor jack method for putting it back together. with the jack supporting under the engine and rolling it on the front tires. This is not optimal but all we have.

Crazy Wheels? Are those Mecanum wheels? if not do you know another name for them?

will probably get a cable come along for the next attempt. Would hate to go through all this again and not get functional results, so any thing else you can think of let me know.

Thank you again,
Joe

Be extra careful using a come along with a floor jack. The tractor may well try to slide off the jack plate if the jack's wheels aren't well greased and easy to roll. Small wheels tend to get stuck easily on any little things on the floor in front of them.

I'm not sure your problem is all in how you're rolling this together as it is in the clutch itself. If there's a gap between the pressure plates and the clutch lining when pedal is depressed, then why doesn't the disc spin free in there? That doesn't add up.
