Quick help - Pinion Depth

Rebuilding rearend, installing new gears, etc. 4th gen 10 bolt, Motive Gear gears. Setting things up, want to check the pinion depth. The pinion face has 3.779 hand written on it - but that is too large to be from the pinion face to the axel centerline.

Am i overlooking something, or does something have to be subtracted?

thanks,
James

I use a honed out set up bearing and go by contact pattern.
You're lucky (maybe not) to even have a number on the pinion. A lot of new ones don't have any numbers leaving the depth setting tool and procedure useless.

With a set up bearing you can have it up and running before you find an answer online.
Especially true when I did my first R&P in the late 80's- no internet help, got that tip from a magazine or and old guy, forgot.

Thanks, that is what i'm about to do - trial and error is annoying

Actually honing the damn bearing is annoying.
But a little easier once you get it done. Good luck.

put back together with factory shims, backlash was good. Going to check the pattern, maybe i'll get lucky and only have to take it apart once.
