I have applied my "engineer" training and determined the PO is to blame, according to my problem solving class handout:

Set screws soaking in PB blaster...not real optimistic about them coming out without a fight though.

Meanwhile, trying to figure out if I can save the existing button.

There is a ridge built up on the thrust button where a groove for the snap ring used to be.

Options:
1: Start the engine and use it as a lathe and try to re-tool the groove with a small file. (engine probably shakes too much while running?)

2: Use a dremel wheel and try to re-grind the groove with engine not running
(I probably shake too much for this option!

3: Eliminate the brake shoe and plate, and use a homemade wear button on the actuator arm instead

Why don't you just buy a new one...... :bash2:

$10.50 each

It's not his fault, his problems solving flow chart is not updated, here the missing part...:biggrin2:

:ExtremeFunny::High5:

He said "engineer", but that looks more like the chart the production workers use.

Cause I'm hearing the voices of 6 rusty set screws calling "just try me" from their deep dark dirty holes!

If they come out, I probably will.....thanks for the link!

Success!.....well, mostly...there were only 5 in there but they put up quite a fight...had to break out the valve grinding compound after soaking, heating, chasing threads, and tapping

The last one made it almost all the way out and then.......snapped in two!....might have tapped that one a little too hard?

Wonder if I can re-use this disc?

Decided to ditch the PTO brake and revert to a button actuator instead.

My machinist uncle had some spare bronze so I drilled and tapped a piece to use as the button.

New clutch disc, new set screws, new bearing and all is good!

Engine was fine all along...cut my first yard yesterday and seems to be working well.

and that as they say was problem solving.....good for you.... congratulations, youre NOT one of the 5 million "Americans" who can no longer do that sort of thing!!

was a good read though...welcome
