Hugh,
Glad to hear about your success! As for the end-float of the crankshaft, if
you can lever the crank noticeably with a screwdriver, then it's time to
replace the thrust washers. I believe the end float is measured at .004 to
.008" . You wouldn't be able to notice this without a dial indicator. I'd
be willing to bet that you wouldn't have to get a dial indicator- just get
a BA screwdriver and lever the crank back and forth. If you feel the
slightest movement- yep, new thrust washers. If you're unsure when they've
been changed, ( if at all), then the best policy would be to put in new
ones. I found out that they should be changed every 50-60K as routine
maaintenance.
Jeff Johnson-
'76 TR6- 56k and yeah, it needed TW's badly
