OK I think I'm close to done if not done. Original pinion and crown gear going back into original housing --All 4 bearings replaced, 2 pinion 2 crown wheel, 2 new clutch plates, on a 4:10 LSD that will be my replacement for the 4:56 that is in the GTV presently when it starts to have problems, or, when my Spider 4:10LSD with 2 new clutch plates only and a preload reset gets noisy!
Pinion depth -- - marked -2 on the pinion, which means I should be at 58.52 face to crown center, right? It is there as close as I can measure it.
Pinion preload -- 15 inch lbs without pinion oil seal
Crown wheel added and preload -- 24 inch pounds total without pinion oil seal -- I think its a bit light but not going to stress on that.
Lash -- measured at 4 revolutions of the pinion gear -- got 7, 8, 10, 9 thou, measured per the book method at the edge of the pinion flange. The 3 thou delta bothers me a little but I don't know what to expect. Its real, not measurement error. This says that the crown wheel isn't tracing a flat perpendicular circle with respect to the pinion I think.
Thoughts? I could take it apart AGAIN and add a thou or two shim on the small end to push the crown out a little, but I am not sure how close I could ever get it without going out of the 6 to 12 thou spec. Every time I take apart and reput together, its a thou or two variable it seems. Am I close enough with what I have now? Appreciate any thoughts or advice -- When the diff starts to break in, I know preload tends to decrease, but what happens with lash? I can argue either way but if RJ is out there reading Dr Jemison what is your advice?
Many thanks to Jim G == he is the man. Could NOT have gotten this far without him without a doubt. Super gentleman.
