I'm in the process of swapping the 2.73 open with 4.10s and a TrueTrac.
I've run into some cases where I don't know what I'm doing (ok, to be fair I don't know what I'm doing with any of this, but this is a new level of lost).
1. From the Richmond Gear instructions:
"Backlash settings are marked on the outside diameter face of the ring gear (illustration)" and "Pinion depth settings are marked on the face of the pinion (also illustration)".
I don't know that I can read what it says:
171270
This is the pinion depth - maybe starts with a 2?
and this is the backlash suggestion:
171271
Surely that's not .150?
The second issue I ran into was "Okay, I can't read these. Let's try this Jegs Pinion Depth Checker, and see what IT thinks we've got with the old shim."
Step 2 in the Jegs instructions: "Zero the dial indicator using the supplied checking block and appropriate extension.. slide into collet until dial reads zero, then tighten."
The handy chart on the back of the instructions says 12 bolts are 4.670", so the 4.3" extension seems appropriate.
171272
It doesn't bottom out in the checking block. Hell, I can skip inserting the collet and it still doesn't bottom out. I'm sure I'm doing it all wrong but the internet is filled with people complaining about these instructions and I didn't find anyone actually explaining it (except a reference to an angelfire page that is no longer available)
The third issue is probably not an issue. I honed out the old inner pinion bearing so it's a slip fit. When I do the pinion depth checking, do I need to have the front bearing seated as well or just let it ride on the inner?
