For turbo engines the side seal to corner seal
clearance should be at least .002". For non-turbo I use nil. So long as the two
side seals and the corner seal will pop back up when depressed, that is enough
clearance.
Measure with the other side and corner seals in place.
Clean the grooves with a piece of broken side seal, sharpened and wrapped with
tape.
Wear gloves in case you break your side seal tool.
If the seals are a bit short and will not lay in the
grooves, just stretch them a bit.
Study the handedness of the oil scraper drive springs.
New springs have paint dots to show a front or a rear scraper spring.
The springs keep the scrapers from
walking backwards as the engine runs. This will wear out the "O" rings and let
the engine smoke.
If using the old springs over again, the paint dots
will be gone, so note that the end that is square goes against the scraper and
catches in one of the many notches in the back of the scraper spring. The
end that is rounded catches in the shallow holes in the bottom of
the groove in the rotor.
It is easier to learn if you mark the rotation
direction on each rotor face. If you can turn the scraper in the opposite
direction with the spring installed, you have the wrong spring installed.
If you get stuck on anything call me anytime, 9:00 AM
to midnight, and I will walk you through it. 740-928-0908

Mark,
Let me send along one assembly problem I had with my 1988
13B...that is be
sure the large flexable sealing rings (round and
rectangular sections)will
fit and stay in their grooves before gooping
anything up..mine were slightly
too small and jumped out really messing up
what should have been a fun
assembly day! (December 19,

Based on
everyone's recommendation I am starting the rebuild process now. I
have a
copy of the Mazda engine workshop manual which lists the clearances
for
inspection and reuse of parts. I am curious if everyone feels that
those
are accurate. In The Overhauling 13b DVD Bruce talks about them being
too
conservative.
That said does anyone have a working phone number
for Bruce Turrentine?
Thanks,
Mark
