Anyone know how to measure pinion depth.

Doing 4:10 v6.

I did it years ago with a toyota mechanic with his special tools.

Can't rember were to take the measurement.

Google I go !!

Thanks. Dirka Allah !!!!!

dave,
You need gear marking compound to check pinion depth.
In adddtion, you need a depth mic to check backlash.

if you don't have these, don't even try.

[stupid] Depth is checked by marks, you can get a tool to get a rough idea to start but your still gonna need to do it by marks

I see the problem, you cant use GM gear paint on a toyota diff. The tolerances are too close....................[cheers]

I don't pay attention to the pinion depth #s even if they are given.
I usually start by installing the same amount of shims that were in the diff before the gear change.
Proper pattern and the correct backlash (measured with a dial indicator) will get you where you need to be.
When checking the pattern, the more resistance you can put on ring gear while turning the pinion, the more accurate the pattern appears.

yes great thread and yes one must apply drag /resistance,load of some sort.. to ensure a good reading on the ring gear, paitence is a must sometimes... And sometimes bam it is good first time..

This one set up bang on the first shot with a bit of math and looking at the old pattern.

I still want yo make a pinion depth gauge setup for doing my diffs.

Luckily I was helped by someone who had the gift of gears.

Once the pinion depth is correct the pattern was perfect.

Ya. I always start with the shim that was on the pinion to begin with. So far, I have never had to change it out for a different one on any diff yet.
The solid spacer is the best idea over the crush sleeve. They cost the same, are far stronger, and are re-useable.
The pic of the busted ring gear is a little troublesome. Did you set up those gears as well? It looks as if the pinion broke only the teeth closest to the inside of the ring gear. Which to me would suggest the pinion depth on that was was set too deep.

And if he set them up the same this time would you not wonder if it is wrong again?????? Just sayin' Dirka.................oh yeah
