Is this gear pattern OK?

The Gear pattern looks good for depth. But not centered
Hes a site of interest. LOTS of write ups on gear installs and pictures.
This guy know his stuff

tc, those look very nice. When turning the gears did you apply some drag to the pinion with your hand and a rag? The pattern looks a little faint, the pinion drag really helps you see what the R&P are doing under load. Make sure the CPBL is good and tight, I just set mine up and fabbed a 4 pin spanner with a 4' cheater welded on... got 'em snug!

It's a little vague.....but looks about right. More resistance on the pinion while turning the ring gear with a 17mm wrench will make reading that easier but I also understand if you don't have a fixture to hold the carrier in that it is hard to do.
The Richmonds seem to always run on the toe. You have backlash set to .010" right?

Zuk, we were going off of the assumption that BL should be .007"-.009", was this in error? He is waiting on a better dial indicator base, we were having trouble with the one we had. Pretty sure we're at .008"-.009"
FWIW, we were able to calculate the shims needed for the pinion bearing, based upon our measurements of the housing, the pinion bearing and race, the pinion head, and the stamped "checking distance" on the pinion head. That pattern was first try, no adjustments.
pinion bearing preload was set at about 12in/lbs, solid collar. Since his previous set destructed due to lack of preload, we were told by a toyota tech to go a bit on the high end, and use a solid collar.
Also, we applied drag, but to the ring gear. turned the pinion.

CBPL is 110 ft-lbs
The pattern actually is more distinct in person, just had a hard time getting it to show up well on the photos.
We used a screwdriver between the case and the ring gear to supply some drag.
As Isaac said, that was the first setup. I run a dimensional analysis lab at work, and I brought home a variety of instruments and we took very careful measurements (to the .0001") multiple times and averaged them and then calculated the shim.
Looks like it paid off - thanks for the input!
