Aha! Dave is the one with 235guy blog. I've run across that a few times... very handy info, thanks!
Jerry, you got me thinking some more & I measured my #4 bearing inside diameter with telescoping gauge & calipers... seems round as far as i can tell within ±.001 confidence I'll claim with the calipers. If it wasn't I'd definitely look for those taper shims.
Do you guys use sealant between the rear cap & block?
The 'best seal' instructions for my rope say to use it, but that seems debatable.
