Subject: Correct TES O-ring sizes

I will outline what we are talking about.
There are four coolant sealing O-rings per rotor housing.
Two outer and two inner.
There are also four oil sealing O-rings per rotor. Two on each side of
the rotor proper. These are located on the flanks of the rotor.
Two per side.

Coolant O-rings:

1.  Inner coolant oring -

    circumference  = 28.625
    diameter       =  9.111
    slot depth     =  0.062
    slot width     =  0.141
    section size   =  0.103

2.  outer coolant oring -

    diameter       = 11.340
    slot depth     =  0.062
    slot width     =  0.110
    section size   =  0.093

This is critical! The proper outer section size is 0.093. Not 3/32 inch
as a 3/32 inch  O-ring is bigger in section size than 0.093 inch.

The TES O-rings are stiffer than the stock O-rings. It is harder
to get them to lie in the groove. Even with Vaseline.  When you buy
them they don't come flat. I found that using a plywood
form to pre set the TES  O-rings works well. Here is a picture.



Paul are you  using the plywood as a form to make the ring to that shape, or
using it to press the ring into the groove?

The water O-rings usually come a wee bit undersize so stretching them slightly
over this plywood form and letting them sit for a couple of days allows
them to take a perfect set and they will lie in the groove no problem.

I think Mazdatrix is going to carry these O-rings. I had a talk with Dave
Lemon about it today and he now seems a bit more enthusiastic.
If everybody interested will send email to Mazdatrix <mail@mazdatrix.com>
it will help matters along.
