Gear setup help!!

I am trying to setup gears and an ARB in my front chevy Dana 44. The Old gears had 30 thousands of pinion shim and no oil slinger. The “New” gears are used from another front axle and had 42 thousands of pinion shim with an oil slinger. I am using an oil slinger with the new setup. For my first setup attempt I used 42 thousands of Pinion shim. All pattern done with backlash within specs.

First Coast


First Drive

This gave the above pattern, which to me looked like the pinion was too close so I went to 30, then 15 and finally no pinion shims.

Each step looked a little better to me but it still looks to me like the pinion is to close even with no shims. I have heard that on used gears it is best to use the pattern on the side that was not worn in previous use. So I figure that this means in the front I should worry more about getting a good drive pattern then coast. Here are the Patterns with no shims.

Final Coast


Drive

It still looks to me like I need to move the pinion away but that is out of the cards. Can anyone who has setup gears before offer any thoughts?

Re: Gear setup help!!

I would say your pinion is a little too close also. And as for setting up used gears you should always try to get as close to the original pattern as possible. Are these new used gears or just reinstalling the orginals?

Re: Gear setup help!!

I would also suggest playing with your carrier shims to see what change you can get from that adjustment.

Re: Gear setup help!!

These are new used gears. Sadly I did not get a pattern before pulling them from the old housing. I am glad to hear that someone else thinks the pinion is still to close, at least I am reading the pattern right. I used an oil slinger on this pinion, and the old setup with this pinion used one. I assumed that the slinger went with the pinion. However, this housing did not originally use a slinger, so maybe that is the problem. I will try playing with the backlash and see what happens.

Has any one used a slinger in a housing that did not originally have one, if so to what effect?

Re: Gear setup help!!

The slinger goes between the seal and the front bearing, not between the rear bearing and the gear.
