O-Ring Stuff - Note that we have identified the outer oil control oring and
the inner coolant oring. We are still looking for the outer coolant oring
and the inner oil control oring. Here are the 'good' numbers:
1. Inner coolant oring
part # = 9319K239
asa568a-175
qty = 4, price = $9.94 each
2. Outer oil control oring (I had no trouble with this one)
part # = 9319K221
asa568a-158
qty = 4, price = $7.17 each
I took these measurements a few weeks ago and came up with the following:
1. Inner coolant 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
McMaster-Carr # = 9319K239
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 diameter. 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
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 # =
9319k221
ASA568A-158

I think those section sizes are off a bit Ken. I think the outer should be
.093 and the inner .118 which happens to be 3 mm. I had trouble installing
a .108 outer.
