Hi Wayne,
Plastigauge is simple to use. And you can measure w/o yanking out the crank.
However, if you've already determined that you had an oiling problem, it
might be worthwhile to pull the crank and measure everything with a
micromoeter. I mention this because it is possible to get "out of round"
problems with the rod journals in particular. And, if this is your case,
you could put in new bearings and still get rod knock when you button
everything up.
As for sources of the parts, try the "big three". Warning: TRF is about to
have their famous winter parts sale. If you _need_ these parts, get your
order in _NOW_. I mention this because three or four years ago I did a
"refreshing" of my TR6 motor, and when I called for the parts (about a week
or so after the sale started) they were out of the bearings and some other
components that I needed to get everything back together. I wound up double
ordering everythng from Moss and in both cases, the longest wait for the
parts was 3 or 4 weeks. Not too bad, if you ask me.
Oh, and I have a pile of bearings at my "disposal" now. Check that, _did_
have. I'm building another motor this winter (and there's a third motor "on
the horizon".)
As for oil pumps, I have not called TRF about one yet (ironically, with
three donor motors, I don't have a good pump), I called Moss about this
less than a month ago. They did not have them at that time. You might need
to call around and get a "used" pump. They have a pretty long useful life -
but you are probably right in replacing yours if it is "grooved".
C ya,
rml
TR6's
