Broke down my 1986 junkyard engine last week and spent a couple days
cleaning with mineral spirits and carb cleaner.  All toerances were well
within normal limits. 0.0005 step were max on housings. Rotor housings
in
real good shape. Found the oil seal from the front housing the the front
cover split in two pieces. This must have been the problem as it is a
high
pressure area. Chasing out the tension bolt holes with a 10mm x 1.25
instead
of 10mm x 1.0. OPPS!!! #$%^*#$!!!  :o :(   Picked up the wrong one out
of my
tap and dye box. I think the threads are toast. Probably a big paper
weight.
Any suggestions.

Ken,

I don't know for sure how thick the casting is around the threads, but you
might try a Heli-Coil repair. You drill out a larger hole and then retap.
The helicoil looks like a metal spring. You thread this into the new hole
with a tang on the coil. Then you break off the tang. The ID is the same as
the original hole and threads. You can use lock tite as well. Not sure how
much I would trust this in an AC, but the race car guys use them.

Good luck,

Monty

Ken contact Mazdatrix. They may have some front housings they will part
with. Also try Dave Atkins or Hayes Rotary Engineering in Redmond Washington.
