R975 help

[Bob Phillips]

Perry,
you should be able to jerry rig up a shaft to see if your flywheel/ clutch assy is heavy on one side. I would be reluctant to have it balanced until it was checked first. Once the snow is melted you are welcome to compare your results with some extra flywheels/clutches I have here.
On aircraft engines the same crankshaft is uesed in 5, 7 and 9 cylinder engines and the only apparent difference is the size of the counter weight. Unfortunately I do not have a book telling the weights of each particular engine so don't know how it compares to tank engine....Bob

Perry. I recall when rebuilding my clutch that the different pieces were supposed to be match marked, and reassembled accordingly. Some of my pieces also had grouped holes like would be drilled durring the balancing process. Wouldent hurt to have it done again with todays better technology. Jesse.

Would anyone know what is the out of the box thickness for a clutch plate as used on a Sexton?

Many thanks.

[Jesse Browning]

I dont know, but to widen the field, it should be the same as a Sherman with radial engine.

Mark,

The Clutch “Table of limits” for R975 C1 can be found on pages 219 and 220 of this manual:

I noticed this posted on another forum. Double check that you don't have one of these installed.
