Back to work on this again. Since I finally got it running and driving again, I have now started the CI rear conversion. The first picture is the donor rear.
In the second picture, it's cleaned, and most of the loose paint stripped off.
I put match marks on the bearing retainers so that they wind up going back in the same way they came out. (Pictures 3 and 4)
There's definitely some gunk in here: (5)
Here's the bare transaxle, cleaned: (6)
Here's the coarse-spline 'guts' (7). I hope that I can use the pinion shaft from the aluminum rear, because the ring gear is shot on this one...there's a crack in one of the teeth. Tomorrow's project is to pull the rear that's in the 1872 and disassemble it.
Question for the experts: The IH manual has all these instructions about shimming the rear bearing cup for the pinion shaft, and I assume this is to get the proper pinion depth/orientation for the spiral-cut gears in the IH rears. The aluminum rear has straight-cut ring and pinion gears, and there are no such instructions in the CCC manual for the aluminum rears...it just tells you to put it together and set the backlash, with no mention of setting the depth. My thought is that it doesn't make much of a difference with the straight cut gears. If I use the straight cut ring and pinion, do I just follow the CCC manual?
