122 PTO Clutch Removal

[Nailhead]

After reinstalling the freshly repainted & rebuilt deck on my 122, I found that the PTO doesn't disengage. I removed the grille, and found one of the screws & throwout levers essentially dangling from the clutch.

I just read the removal procedure in the 122 service manual, and wondered if anyone had anything else to add, or any thoughts on why that screw worked its way out.

Thanks.

I just went thru the dangling PTO finger myself. I figure it was just the double lock nuts loosening up to allow the screw to work it's way out.

I just reassembled mine ( setting with the correct gauge ) and it's working fine.

As far as added suggestions, only use a high quality 1/8" allen / hex wrench on the set screws. If you use a cheap one and it rounds off the hex, you're in for a boat load of fun and excitement to get them out.

There will be TWO set screws in each of the three holes. The longer pointed ones go it first and locate the PTO against the bearing while the other one is a lock.

If the PTO seems stuck after you have all the set screws out, use a piece of hardwood in the V belt groove to tap it out. A tap or two , rotate the engine and tap again. Keep rotating the engine to keep it even as you work it out. I put the piece of wood under the carb as that has the most room.

Jeff, thank you very much for that. I just want to get this thing going & mow a little grass with it.

I argued with my mech. PTO on my 147 for about 6 months to get it just right. Had it rebuilt, it slipped, then a bolt fell out and almost lost the parts (throwout lever, etc). Got it set up right now.

After giving it a second look this morning, I noticed the clearance notches in the tin fixture surrounding the PTO are nowhere near where they should be, so I'm going to have to delicately cut some with some snips in order to get a wrench to those set screws.

Does anyone have a better idea? Should that gear-shaped tin thingy turn?

This little tractor packs a lot of frustration into a small package.

You should be able to push in on the center button of the pto (although it may be really hard) then turn the pulley so the set screw holes line up with the cut outs in the basket.

Or use a puller to apply pressure to the thrust button,rotate till the holes line up.

I think I read somewhere that just tapping the center button with a hammer while you put rotate pressure on the basket, it will move a little bit with each tap. Never tried it though.

I have tapped the center button on the PTO with a dead blow hammer to get the PTO to rotate a little at a time,

Thanks everyone!

I forgot to ask: where do you get the setup gauge for the clutch?
