High rolling resistance 8.75 gear pattern update

[What’s up dock]

Hows your backlash with this set up?

Current backlash is .006

.090 shim? I’ve only worked on a 489 so a 742 must be a lot different as far as pinion shimming goes. I think you still need to try to work on getting a little clearer tooth pattern particularly on the coast side.

So far this is as close as ive gotten so far. Current depth is set at .090.

To me It's still a touch deep on the pinion.

Best I can tell from pics and the manual it's pretty close. Thoughts?

That looks about as good as you are going to get. I would slap it in and try it.
Most of the gear sets you get now make some sort of noise.

I think your pinion depth may be very slightly to great from the coast side - kind of hard to tell as the pattern is still a bit indistinct. But the drive side looks pretty good. All in all, I agree with Steve340, it may be pretty much as good as it gets. See what dvw thinks.

Ok, thanks guys!

Used gears are sometimes difficult to get a real good pattern. R u holding the ring gear with a cloth or towel to create some drag when your turning the pinion? If so send it. Kim
