Gear pattern check - Please?

This is on a HP Dana 60, if it matters.

1st try. Backlash is set at .007. Pinion depth looked good on the coast side, but the drives side looked deep to me.

2nd try. Backlash is set at .006. I removed .020 from the shim pack behind the front pinion bearing race. It's not the oval pattern they want us to shoot for, but it still looks good to me.

jeeperjohn would be a good guy to ask about this. he knows his gears.

That's an acceptable pattern. I would like to see how it looks on the other side of the ring gear for comparison.

I would have run the first one. The second one would work too though.

With the pinion that deep, wouldn't it cause excess wear and possible heat on the tips of the pinion gear?

looks a little deep to me to but after stairing at the pic it may be a opty.

I brushed the marking compound on a little heavy which is whats causing the line at the flank of the tooth. Maybe that's why it looks a little deep.

You need to apply more pressure on the gears while pulling the pattern.

Yes, running the pinion too deep heats up the gears causing excessive wear, changes in the heat treatment of the gears and possibly premature failure. Make sure you put a super strong magnet on the inside of the diff cover when you put it back together to catch wear material. Also make sure you follow the manufacturer's break in instructions.

That's a decent pattern.

Awesome! Thanks for the help, fellas!

Lockright, but you're close enough.
