Im sitting in the garage and Im tryingt to figure out why my pattern wont setup correctly. I have tried three different shim and adjusted the backlash differently within spec and I cant seem to get the pattern down in the teeth further. I can easily get the pattern centered on the ring but when I take away a shim and readjust the backlash the pattern doesnt go any deeper. Here are some pics of my current pattern, so far I have gone from a .0020 to a .0010 to now no shim at all and it hasnt seem to help the pattern much. This is probably then best I can get it at this point. And my backlash is right around 8 thou.

looks like it's not working out for you man. If your still at it tomorrow I'll come down and give you a hand. btw my battery on my cell keeps dying so I've probably have tons of missed call. pm me your address again.
 
I started with a .020 shim and the bl running .005-.008 and the pattern was actually running higher on the ring gear.Your help is appreciated...thanks.
 
BTW, the .020 pinoin shim will probably be too much. Do it anyway though so you will have an idea of what to look for in the change of the pattern.

Don't be too concerned about getting the pattern centered on the tooth until you figure out the depth issue.

I just re-read your post and see you have the BL at .008.
 
True but no matter what shim i use be it a .020,.010 or non at all...it doesnt seem to be moving the pinion any deeper into the ring gear.This is with the bl adjusted to .008 each time the shim is changed.
 
New ring and pinion?
What size shim was in there before? Or did you start with a bare housing?

The most shim I have ever put in a 14FF was .027, not that I have done lots of them, so you should see a difference between .000 and .020

Do you have any pics to show the difference.


edit: (for drunken spelling)
 
The original shim was a .020 and I started with that. Then went down from there. My friend is doing the typing while Im am doing the work. I am going to attemp to run a .020 shim again with a little tighter bl at .006 The gears are new, I have checked the axial and lateral runout on the ring and I got a variance of about .003, when I check the backlash in four places on the ring I do get a variance of .003 I dont know if that would have anything to do with it.

I second the edit ofor drunken spelling...
 
Ok, its have done many many shims and backlash adjustments. what I found is I cannot get the pattern towards the root anymore. I think it might be possible that my housing or pinion support housing needs machining. With no shim at all the pattern is still a little high on the on the gears. I put around .030 worth if shim and the pattern was way on the end of the teeth. I may have no choice but to run it. Which really sucks. I really appreciate the help you gave me, I have seen that you had helped a few others so I had to bother you.

No, No, No,.... Don't run it like that.
Look at the pictures you posted again. The pattern is too close to the root already so why would you want it deeper. The pinion is already too deep.
