the pto on my 105 has been slowly not disengaging until I was finally out of turnbuckle adjustment and it destroyed my wear button today when I got the tractor finally running.
The symptoms were: able to spin pto pulley freely when pto lever was "engaged" and wear button was not pressing on thrust button.
with lever pulled back into "disengaged" the pulley would spin with the motor.
I pulled the clutch off today and found the clutch disks to move freely. I figure this can't be right since with no pressure on the thrust button ala engaged, it should be pretty tight. When I push the thrust button from the inside it does indeed lock up like it's supposed to.
I wasn't thrilled to see this:
I'm guessing I pressed on those triangle fingers so much that they were rubbing on the shaft that the bearing sits on which was turning the PTO pulley, not the friction disks.
I don't have an adjusting tool so I guess my question is, can I just trial and error the adjustment on this thing to get it close enough where it engages/disengages? The nuts are currently at the end of the bolts. How tight does the friction disk need to be when the thrust button isn't being depressed? thanks! Snow's comin!
