Stupid Clutch Question

[greg_g]

Unless the OP has made an error in reporting the facts , "the evidence submitted so far" points away from that being the case .

Have it your way, but I think it's putting the proverbial cart in front of the horse AND ignoring the evidence that this happened while the tractor was actually in use when this occurred. Competent troubleshooting involves eliminating the simplest and most common reasons first. Broken roll pins are simple and well documented. A seized clutch disc on an active 200 Series - is neither.

My apologies SPYDERLK , I completely missed your post about the sticking clutch plate spline when I posted . I was wondering what you meant by 1st and 3rd the motion .

It does sound like the most likely cause if there is no change in pedal feel . If it were a sheared roll pin the shaft would simply rotate back and forth in the throwout fork or clutch lever and the pedal would just go to the floor with little resistance . This diagnosis fits with the fact that GDC said there was no change in pedal feel . But whatever the cause , this is not a Peeing competition we are here to help GDC with an answer .

In our shop, the few cases we have seen where a clutch would not disengage, with minimal or no change in the feel of the pedal, were the result of a portion of the lining coming off teh clutch disk and wedging itself between the disk and pressure plate or a broken clutch finger allowing part of the pressure plate to remain engaged on the disk with the clutch pedal depressed. Unfortunately, both of these require splitting the tractor to repair, you might be able to see a broken lever or finger through the inpsection hole if the SHinniu is equpped with one. best of luck.

I had purchased a "supposedly new" Jinma 284 (Found it was 2008 ID with 9 hours on the hour meter) in the end of 2009. I did five hours of run time (3 of those were with back hoe) and the clutch was gone. The dealer charged labor and the parts for replacement. When I questioned him, he said I must have done something wrong. In 2 hours of using the clutch for the bucket loader? I was informed from another dealer that it was not uncommon for a new Jinma to loose it's clutch in 50 hours of use, but 5 hours was kind of quick. Not impressed.

I have 150 hours on my original clutch, most clutch failures are caused from not setting up the clutch right to begin with. You really have to check your free play. My dealer (Chip) also warned me about riding the clutch. Get your foot off the clutch!

I have 750 hours on my clutch with no issues. It was set at new and again at 550 hours. I would say it was never set at the on set and you got taken on the supposed warranty.

Any ideas as to why a new clutch might suddenly stop disengaging? I had a new clutch put in my Shenniu 254 last summer and everything was just fine until I was plowing snow the other day when it suddenly stopped disengaging. There was no change in pedal feel or any noises; just all of a sudden, depress the clutch and keep going.

Thanks

GDC,
Any update as to what the original problem was?

Have you had time to check it out further?

Sorry for the delay in posting the solution, i got really busy and well.. you know how things go. It was a broken finger on the new pressure plate. It is running strong now other than a bad radiator cap. Jim's farm equipment is out and not sure of resupply. I have a call in to Hardy Diesel on the off chance that they have one left in stock.
