Jd 40 won't turn

Post by ratskinner » Tue Jan 20, 2015 6:26 pm

the right side will not turn .I have looked at it the band clutch seems to be grabing the drum .But i notced that the band clutch is wet .so i think that might be my problem .If it is how do i get it dry with out taking it out?
IT looks like it got oil on it some how.

If it is getting oil on it the seal has failed and needs replacing.
Virtually impossible to clean the oil out of the brake lining.
Time to pull it apart and replace.

Happy wrenching,
Duke

After doing some more reading and thinking .I have come up with this thought that the clutch is rusted to the fly wheel on the right drive side. I say this because when I pull on the right drive handle I can hear the motor trying to labor .
Also I am new crawler owner and I am not a 100% sure how the drive system works .this is how I think it works you push on the foot pedal and that disengages the clutch between the motor and the transmission, then on the steer side or drive side has its own throw out bearing and clutch and band brake for both sides .By pulling on the handle you inguage the throw out bearing to disengage the the drive clutch and to engage the band brake to lock up the track for it to turn.

Hi,

Yes, I agree that if the engine loads down when you pull the lever and it won't turn, then it sounds like the clutch is stuck and the brake is working.

It is possible the clutch pack is stuck and also possible the adjustment is incorrect to where the brake is coming on prior to the throwout releasing the pressure plate.

Hi,

Oh, yes. Oil. Not good at all. Might also be the fiber clutch pack discs are swollen. I agree. Time to drop the track and pull the final and fix it properly.

And, I hate to say this as it means more work...Do the other side as well. I learned a long time ago to do both sides.....
