ring gear contact pattern
Pelicans-
I need some help. I've reached the point in my 901 case swap where I'm setting up the pinion depth and backlash. I had no luck finding someone willing to loan the the pinion depth tool so I've opted to use the mesh pattern dye method. [img]Any advice? Try again with yellow or white grease? Thanks, Jim Edited 5/17 to delete incomprehensible pictures. Last edited by Jim_Brown; 05-17-2006 at 12:39 PM.. |

Hi Jim,
I'll wait for some professionals to chime in but in the mean time here are some pics of my 911/01 that I just finished taking apart due to the simplified diff failure. ![]() ![]() Don't know if it will help or not as it seems you have the same pattern marks on your gears from prior use as well.

After doing a little reading, I realized my posts are of little help to you. I hope you get the clarification you need from those who are more experienced.

Thanks. The pattern interpretation link is a good one.
I've tried again with lithium grease as the marker (applied a lot thinner than the prussian blue) and a better camera. Here is where I am now. Drive side contact is low at the toe and fairly centered on the heel with no contact at the margins of the teeth. ![]() Heel contact on drive side: ![]() Toe contact on drive side: ![]() I thought about reducing my pinion depth a little to bring the pattern up but I think it'll take me up to the edge on the coast side. ![]() Anyone? Thanks, Jim |
