I was only able to adjust the backlash in .005" increments since thats what shims came with my richmond kit. I adjusted the pinion shim to .038" and adjusted the carrier by .005" and the backlash ended up at .012".
Personally, Id like to stay at .010" or lower, but not sure if the allowance works both ways. Ive found through research that .008"-.010" (.010 is stamped on my gears) is where you want to run it, so not sure if .012" would fly?
If I went up to .040" would this tighten up the backlash if I left the carrier shims the way they are? Or should I just run with the .035" pinion shim and take everything back to the way I had it in my second pattern I posted?
