My endplay is .09 before the spacers and flywheel bolt on. The 3 spacers measure .004. Ultimately leaving me with .05 end play. Is this OK? Seems like a lot.

Do you mean .005? as in 5 thousandths or .050 as in 50 thousandths? 50 thousandths is probably about 44 thousandths too much.

I've found that the best way to measure everything is to bolt everything together with 3 spacers and then measure the endplay. Better to install and measure 2 or 3 times, then to add up measurement errors, or make slightly incorrect assumptions.

I should end up w/ .003 after the shims |

I hope it's a good dial indicator. I tried using the feeler-gauge setup, and did not like the variability of the results.

(IMG:style_emoticons/default/blink.gif) Dial indicator, feeler gages, digital calipers, you name it. The more I can confuse myself now the more excuses I'll have for later. (IMG:style_emoticons/default/lol-2.gif) How's the new digs? Did you get moved in? QUOTE(Dave_Darling @ Jun 4 2011, 11:23 PM) I hope it's a good dial indicator.
