154 PTO Clutch Cup

Postby Bob cramer » Sat Nov 05, 2016 2:37 pm

PTO Clutch is in need of replacing as I was only able to get 15 foot lbs of torque before turning while engaged. Upon pulling the clutch assembly I noticed the clutch cup had numerous cuts in it possibly from the cams rubbing up against it while engaged. If I replace the PTO assembly should I replace the cup as well. Not sure I know what the cup does. Does it just protect the PTO or is balance an important concern while PTO is engaged? Thanks for your feedback.

The PTO friction disc's lugs/cogs engage in the cups slots. The cup is the drive portion of the clutch assembly.

The slots in the cup take quite a banging when initially engaging the clutch. Depending on how beat up the slots are, might want to replace the cup along with other clutch parts.

Few years back I worked on the PTO, mostly replacing bearings. I took a file and cleaned up the burs on the cup and friction discs, then turned the friction discs around, presenting a new uniform surface to the cup slots.
I have an excuse. CRS.
