Pinion depth guage

In the installation tape which came with my Richmond ring & pinion, they show a pinion depth guage which mounts in the carrier bearing bores. I can't find anything like that.
Can anyone direct me to such a pinion depth guage?
Thanks, Johnny

Snap On has one, but you would have to mortgage the house.

I have built a number of rear axles over the years and have never needed such a tool, the gears and housings are made with such precision that unless something is warped you won't need it. Put the pinion in at stock depth and adjust the ring gear to get the pattern, check the machined bevelled edge of both gears with a straight edge to make sure they are parallel and your done. This is all I have ever done and it works, if things don't work out it's because something is bent, cracked or misaligned. I seen one that didn't work out once (9" Ford) and it turned out the guy brought us a center section out of a car that was in a serious fire, he had bead blasted the center section before he sent it to me so I had no idea. The housing was distorted and not worth saving unfortunetly.

Its a simple procedure that gets complicated by unnecessary measurements.

You can get one from Jegs, Mark Williams or probably Richmond. I would encourage you to get one and use it.

You can bet the guys at Strange, Mark Williams and the factories are using them everyday, all day. Get set up for a back lash indicator also. After you're right on the nut, check the wear pattern with grease. Your gears and bearings will thank you for this.

The trouble with factory cases is that they have a plus or minus tolerance factor that will pass Q.C. If you have before you a case with tolerance "stack up", it will be significant.

After you attain a thorough understanding of the engineering associated with gear sets you can recoup your investment by setting up rear gears for your friends.

If you ever run into a warped case, you'll know it before you can finnish setting it up and get it out the door.

Look on the end of your original pinion gear... usually they will have the +\- stamped or scribed on it.

I've checked Jeg's, Summitt and Richmond Gear's web sites. Also checked Snap-on. Found only the one pictured..Which I bought. I'm sure it will do, but I'd rather have the one like is shown on their video.
Thanks for your responses,
Johnny

I have one like the one pictured but sold by another company. I hope yours is better than my mine because mine is crap. I tried to use it a few times and now it's been on the shelf for over 5 years.
