Hi Ed,
I obtained the measurements for the Inner and Outer coolant
orings by laying a piece of #12 wire in the end housing coolant
oring groove, then I measured the length of this piece of wire.

I measured these last week and came up with the following:
1.  Inner water oring - part # 9319k239 ASA 568a dash 175 (just
for the record I think you originally identified these)
circumference  = 28.625
diameter       =  9.111
slot depth     =  0.062
slot width     =  0.141

2.  outer coolant oring - no part number for this that I could
    find
    diameter       = 11.340
    slot depth     =  0.062
    slot width     =  0.110

I measured the oil control orings 2 different ways.  First, I
measured the metal scrapers with my digital calipers.  Secondly,
I cut an oring and measured its length to obtain the
circumference and divided by pi to get the diamenter.  I also
got the sectional values by measuring the orings.
3.  Inner oil control oring -
    outside diameter of scraper ring = 4.559
    depth of scraper slot            = 0.097
(Note that I could not measure the inside dia of the inner oil
control so I had to calculate it.)
    Total thickness of oring / slot = 0.097 * 2 = .194
    Inside diameter of scraper ring = 4.559 - .194 = 4.365
    Circumference of Mazda oring = 13.75
    Dia. of Mazda oring = 4.377
    section thickness of Mazda oring = 0.103 high by 0.134 deep
    McMaster-Carr # =
    ASA568A-245

4.  Outer oil control oring -
    outside diameter of scraper ring =  4.995
    depth of scraper slot             =  0.080
    Total thickness of oring / slot = 0.08 * 2 = .160
    Inside diameter of scraper ring = 4.995 - .160 = 4.835
    Circumference of Mazda oring = 15"
    Dia. of mazda oring = 4.775
    section thickness of Mazda oring = 0.105 (shape is round)
    McMaster-Carr # =
    ASA568A-158

Ed, I failed to write down the McMaster-Carr part number for
these last 2 items. I will do so tonight and get back with you
tommorrow.

Also note that Hayes sells teflon encapsulated orings for the
oil filter pad (part # - PER 622) and the dowel pins (part # -
PER 620).

I plan on ordering all of these also just as soon as I can nail
down the requirements for the coolant and oil control orings.

Thanks,
Ken Powell
