Can someone tell me if this gear pattern is ok.

After 6 hours, and lots of use of the BFH [img]/wwwthreads_images/icons/smile.gif[/img] I think I got my ring and pinion set up right and need a little advice from the gear experts. Here's a picture of the pattern. What do ya'll think? Backlash is .007" and I've got 15in-lb of preload on the carrier bearings (within specs for a D44 according to the chart I'm using.)

I'm not a gear expert, but I've done a few, long ago and far, far away. It looks to me like the contact is too close to the inside edge of the ring gear. Your wear pattern should be pretty much centered on the tooth.

It looks like a lot of people missed out on a lot of posts when the BBS changed over. Maybe this will move your post back up front where one of the experts will see it.

Nope the pattern is still off and you need to add a little bit more backlash. 7 is on the really tight side. You should have between 8 and 12. You want those wear marks right in the middle.

I think you are in a little tight, you may also need to adjust the pinion depth. I think I would move the carrier away from the pinion a little and see how the pattern looks. I am afraid that you may end up being too far out on the toe of the teeth and may need to adjust the pinion depth to get the pattern right. But with the tight backlash you might be able to make it.

If you look at the date on the first post, it was from last year. Glad to hear the gears are doing all right so far. At least we got an update.

I made more changes after I posted that pic, and everything seems to be working fine. Don't have any weird noises or anything. I'll be changing the oil soon, so I'll get to see how things look, I'll probably run a pattern again.
