R+P pattern pict. - What do you think?

[FrankenRover]

Here is a pict of the pattern we ran on the GBR 4.75 reverse cut R+P. The backlash is 6 thousanths. We used a 54 thousanth pinion height shim. What do you guys think? Could it use a little more pinion height? Backlash is already at near the maximum, and decreasing it any results in the pattern being closer to the heel side (inside). The pict actually looks pretty close to the LR service manual picts for a correct pattern.

Thanks for any input,

Here is another view.

mmmmm, I am by no means a diff expert and have never set a set of gears properly but.......

if thats the pattern your getting at the maximum backlash limit I think that given these are brand new gears and these gears are going to see some really high loads I would want the backlash to be at the minimum setting with the same pattern.

I would raise the pinion and go again. You know you want too, its only time.

Did Bill tell you the suggested backlash for the gears?
I prefer to have them at about 4 thousanths.

I've done a few sets of the standard GBR gear and that pattern is not really good.
The pattern should be more of an oval shape with soft edges all around
I can't remember which way you should go to get the pattern more satisfactory so I'm not much help
Just keep trying.

When I did my first one I made a chart so I could keep track of all the patterns and shim thicknesses, cause sometimes it seems like you are going in a circle and never getting the right pattern.
