Re: d44 pattern check

Way off. What's the backspace? Looks like bad pinion depth to me.

Re: d44 pattern check

Need to go way deeper. I would definitely add at least .010 more shim to it. The pattern needs to look like an oval. You only have a half oval. The oval needs to go deeper into the gear than it will look more normal.

Re: d44 pattern check

yea the pictures i had gave no explanation, so i thought the pattern had to be centered from the id to the od. like i said, first install
i found another pattern chart that explained it better and i'm working on it.

This is what i misunderstood when i first did gears.

Carrier shims are ONLY for adjusting preload (and naturally you need the right amount to make sure the carrier fits tightly in the diff).

The pinion is where you make adjustments. You only make adjustments to the carrier to make up for the changes you made to the pinion.

yea, i try keeping the backlash in spec when checking it, but i only adjust the pinion depth for checking the pattern.

I do my own gears I know. I'm just saying to compensate for the pinion adjustments to adjust his carrier shimming from side to side as well.

Re: d44 pattern check

Carrier shims set preload and backlash.
