I installed a new clutch, pressure plate and throwout bearing even though old parts looked very good. I am now able to get correct free travel, however I am almost out of adjustment already! I checked all linkage for wear or sheared pins allowing shaft to rotate where it shouldn"t. All I can figure is maybe flywheel has been ground too many times. Does anyone have a spec to measure for proper flywheel thickness? [Reply]   [No Email]

Could the engine have come from another machine? Sometime between the 600s and 601s they changed the thickness of the block plate back there. Went from one about 1/8" thick to about 1/4" thick. If someone dropped a 601 engine in it and didn't use the correct plate you will be pulling hair figuring out how to get the clutch adjusted. I don't know your NAA as well as the later models but you might check your block plate. I'm thinking it should have the thinner one.   [Reply]  [No Email]

"...looking in all the wrong places.....". Seriously doubt a few thousandths here & there can impact the comparatively large throwout bearing/PP finger travel.   [Reply]  [No Email]
