Lately I've been having problems with grinding when engaging the PTO, so I figured it was past time to take a look inside the bell housing and adjust the PTO clutch. This tractor has 530 hours on it. I first checked the clearance between the release bearing and fingers, and it was pretty wide (about 3/8"), so I had quite a bit more than the 1" spec for free play. The fingers do show some wear, but I don't think they've worn 1/4" (I think the adjustment was too wide when it was new, but I never looked so I can't say). Anyway, if I use the linkage to adjust the clearance between the release bearing and fingers to 1/8" (for 1" of free travel in the pedal), the pedal is quite a bit further down and I won't have enough travel to disengage the PTO clutch because the safety switch is at the end of it's adjustment range. Should I use the main clutch adjustment to set the free travel between the fingers and the release bearing? If I do it this way should I disconnect the pedal linkage so the release bearing is all the way back? The PTO adjustment seems to be pretty straightforward, but I'm more apprehensive about touching the main clutch. Any guidance or insight would be appreciated.
