Hi all,
I need to get the pinion preload reset on my 741 (it is too tight from a previous rebuild many years ago) and want to buy a set of shims to give to the diff shop. (BTW , I'm in Australia so not much info around on these 8.75's, and differential shops usually are not familiar with old Chrysler stuff).
I am sure that only the 489 used a crush tube /crush sleeve with shims whereas the 741 used only shims. Is this correct? Because I am getting confused with places like Ratech and Dr Diff who are selling install kits for 741 and both have a crush sleeve in the kit (eg see this page:
http://ratechmfg.com/chryslerstandard.htm)/ Ratech has listed for the 741 and 742 "CRUSH SLEEVE (shim pack)" Part # 1107. Which is the same as for the 489. Dr Diff has a Minimum Install Kit for 741 and shows a crush sleeve also.
So which is correct? Maybe they sell it in the kit but you just don't use it for 741 / 742?
ALSO, is there different shims I should get for either side of the pinion? Or just one type of shim style (varying thicknesses of course). As I seem to be seeing different styles of shims also -bit confusing!
Thanks for your help!!
