The first action (after this email) is to call the
machine shop tomorrow, but:
Installing a camshaft last night on a block with new
Vandervell cam bearings, the cam was too tight.
Micrometer on 1st and last bearings showed ~zero
clearance. APT website says:
"After the bearings are installed there are usually
high spots that bind the cam a little and the best way
to try and deal with them is to go over them with a
kitchen scouring pad which scuffs them up just a
little and normally does the job. If there is a tight
spot you may need to look for the shiny spot on the
bearing and carefully remove it with a bearing
scraper."
This seems a little unscientific. In several previous
rebuilds, I have not had this problem, so the phrase
"there are usually high spots" is new to me. Machine
shop is reputable, camshaft is reputable, bearings are
reputable, I am questionable, and don't want to take a
scotchbrite or dingleball hone to a bearing surface.
I haven't wiped a cam yet and don't want to start now.
Any opinions/experiences?
