paul, the outer coolant o-ring that you sent to me is an exact fit as
far as
i can tell. if you can provide that part number to Ed Anderson he can
complete his list maybe. Tom Kimsey

OK Tom. What about the inner coolant O-ring and the oil seal O-rings I
sent?

Paul Lamar

Ok Paul,
    A beer the next time we meet  - in return for the part number for the
outer coolant "O" ring {:>).  Between Ken, and me, we  have the oil control
"O" rings in both Teflon Encapsulate Silicon and Viton.

Ed Anderson

The problem is Ed, the ones I sent Tom were bought from All O-Rings and they 
do not use standard nomenclature or part numbers. I don't think I ever
calculated the part number using standard nomenclature. I did a search on
the CD but could not find it.

It is easy to measure the slot in the
end housing. I know you have some lying around. Consider the slot a circle
cut in half with two straight sections inserted between the half circles.
Measuring across (horizontal) will give you the diameter of the two half
circles. Measuring the long (vertical) way will give you the diameter plus 
the length of the straight sections.

Use a dial vernier caliber to measure the slot width and depth. The depth
dimension is the important one. As I recall the slot depth is the lessor of the
two dimensions. Use the slot depth and add about 20% for squeeze and that should
give you the section diameter.
