'85 LSD Rear End Ring Gear Lash

When setting the lash with a dial indicator on the ring(crown) gear (85 lsd rear end) What is the proper lash in thousands (0.00) between the ring and pinion gear? Is there a web site or link on rebuilding 1st gen rear ends?

Nobody out there has the shop manual for the '85 RX7? It should be in the mazda shop manual, not the Haynes.

0.0035-0.0043 Download the FSM, there is a lot more to it than just adjusting the backlash.

Thank you, Yes I know that there is a lot more to it than just the pinion/ring gear lash as I work on marine gear sets(main propulsion reduction gears) as large as an RX7. What is an FSM? Does this mean "field service manual." Where do I download it from?

I have the FSM hosted (1985):

http://oregonstate.edu/~abelk/Manuals/

Check section 9. I will loose my hosting in a couple months, so download now. You can also get them from: http://www.wankel.net/%7Ekrwright/ca...85_manual.html This is where i got mine from. My connectrion should be faster though.
