The Stovebolt Site Forums The Shop Area General Truck Talk Random PTO trivia - Muncie PTO

I found that I have a Muncie brand PTO on my 1 ton.

Now...after calling Muncie my model was actually made by Chelsea.

It is the PT - A2HW. The PT's are Chelseas and the PH (I think) was the Muncie built Muncie.

Backlash on the PTO is very important. (This is the tightness of the teeth on the PTO gear and the tranny gear.) Backlash is set by the gaskets...yep.

So I found a place here...(Inland Truck Parts)...that has the gaskets on hand. Muncie was very helpful on the phone, Inland Truck not so much. But I have four new gaskets now. (2x 0.001 & 2x 0.002) The goal is to use them in a combination that will set my backlash.

This old PTO does not have a cover that can be taken off to see the gears. Backlash is 'guesstimated' by attaching the PTO and turning the output shaft by hand...(I'm assuming I should feel some play, but not a lot). So far the answers on backlash have been a bit less than scientific.

There you go...all I know...about the PTO

(Cool rhyme.... )

This is on a SM 420 transmission, right?

If you pop the transmission into neutral and remove the top cover with the shifter still intact, you can see right down into the gears and measure the lash with a feeler gauge or dial indicator. It is pretty easy to re-install the top by lining up the shift forks with the synchro rings and bolting it back together.

Ya'll can sure make stuff sound simple!! But as a wrencher that is learning as he goes...that sounds a bit over my head. I don't know what a shift fork is...
