I have an 870 that the PTO quit on. I thought for sure that the clutch disks were probably worn. So I pulled the PTO unit out and tore the clutch apart. Replaced all the clutch plates and separator springs, which were totally worn out. I thought for sure I had the problem solved when I saw what the old ones looked like. There were even pieces worn off of some of them. I also replaced two o-rings, and two seal rings, put the thing back together, set it back int the tractor, hooked it back in the TMR wagon, and it was no different than before. So then I disconnected the oil line that goes from the flow divider to the PTO clutch, started the tractor and engaged the lever and oil came out of the line. I also checked the pressure at the flow divider and 170-180. My manual says should be 180, so I didn't think that was the trouble. With nothing hooked to the tractor, I can take a pair of vise grips and clamp them on the shaft, engage the PTO, nudge the vise grips a little bit then it will take off. But that doesn't help me much! The way I read the manual the problem would have to be either in the hyd. pump, the flow divider, or the PTO clutch, which I just got done overhauling. Does anyone out there have any ideas for me? Any help would be greatly appreciated. I need the old girl pretty bad. Oh, hitch arms raise and lower, remotes work, I haven't had powershift 2 in any range now for about 3 years, and there was an instance a few days ago I lost the clutch and power steering, but it came back then in a minute or so. Right now I just need the PTO! Thanks.
