Rhett and Phil,
I am not sure what crankshaft endfloat is - might I know it as endplay in the crankshaft? The fore and aft movement of the crankshaft? I am not sure how to verify that condition. I imagine that I need some to allow the rotating assembly to spin around.
The noise that the system makes starts when the throw out bearing starts to spin - all the way to the end of the travel of the fork. The failed ball bearing noise is as if there were no lubricant of any kind in the rotating assembly. All racket stops when the clutch pedal is released and the bearing stops spinning. Oddly, the bearings are full of lube when removed - and seem OK. The clutch seems to release OK when the pedal gets pushed in when the freeplay is adjusted per the book.
I have only experienced this condition at idle - and it is not really loud - just enough to let me know that something is amiss. I put some grease on the splined shaft and it seemed to shift all right. The tranny guy suggested antiseize would be better - and very little so as not to contaminate the friction material.
I did not want to pull the pressure plate and disc but it seems like they need to come out to do the runout veriifcation that the manual advises. I am busy getting the T-16 for a Warriors Day parade on Saturday so any more ideas that will keep me out of that rotating assembly would be greatly appreciated.
Has anyone ever done the repairs to correct a misaligned transmission whilst installed in a CMP truck? I really don't want to wear out the bolts that hold the sheet metal on by removing all that kit (again).
I appreciate you musings on this - even Peters
