PTO Clutch Rebuild on 126
 

I rebuilt my PTO clutch using a parts kit and all was well for about 30 days of use. Yesterday the mower stops turning so I take the front screen panel off to look a the belt and there lies half of the clutch parts (bolts, throwout levers, clutch buttons, etc...) on the front of the frame.

I can only assume the nuts (which would include the locknuts) came loose from the bolts that hold the assembly together. I will rebuild but looking for thoughts on what I did wrong. Do I need to locktite the nuts on?

Did you double nutted the nuts together tight enough after the final adjustment? I never had locknuts but if you do, they shouldn't be nylon locknuts because the heat can melts the plastic.

Thanks and yes I didn't actually use "lock nut". That was just my vague term for using the "double nuts" from the original configuration. I had the first set of 3 nuts tightened down to the right specifications using the gauge and then the second set of nuts tightened down really snug on the first set of nuts.

You need to use 2 wrenches on those nuts to really lock them together.

Best bet, pick up a few cheap 7/16 open end wrenches at the next swap meet or harbor freight and grind them down "skinny" to grip the bottom bolt then crank the lock nut down tight on the bottom nut.

Thank you, will do

A little bit of blue Loctite would not hurt anything.
