125 pto
 

My PTO on my 125 slips so I am trying to get it off to rebuild it. I have the set screws loose but it won't budge. Am I missing something?

:bigthink:

There are two sets of set screws. Three holes; two in each hole. Did you get both sets out? They need to come all the way out. If they don't want to budge try some PB blaster (or equivalent) down the holes first. Once you get them out, the PTO will come off straight. Normally the PTO doesn't like to fall right out; I've had to nudge mine along on the points side of the engine with a hammer/punch- an old hammer handle as a punch where the belt goes- tap a bit, rotate the engine, repeat.

thanks, I will see if can get the other three tomorrow.

Take your time, be patient. Plenty of PB Blaster type oil. If you get one to bust loose, only to have it stick again, apply more oil and drive the screw in and out. Do what it takes to keep from having to drill those out. I'm a fairly decent wrench, and I managed to ruin my first PTO.

make sure your using an allen wrench that is "fresh" on the business end.
Sometimes I will grind the end off until the wrench is "new" all the way to the business end.
Using a worn allen wrench in the tiny set screws is inviting the likelihood of rounding out the hex socket in the set screws.

thanks guy's. I had to use all of the tricks plus one of my own.
the first set screw in each hole would come loose but then stick at the top of the thread so I tool a 5/16th drill bit and drilled out that thread and was able to get the screws out and the clutch off. I am going to take it apart this afternoon. the fiber friction disc doesn't look worn to much so I figure to try adjusting it and see what happens.:American Flag 1:
