Mark,

Kelly Troyer, sent some end housings = to Jeff=20 Chrysler of Creavey, to make absolutely sure of sizing. Jeff promised = me that=20 he would hold a record of the proper size for all Mazda Rotary = requests.

The sizes ID by Jeff where as you have = stated.for the oil seals - and Coolant seals are

PFA-Sil 0.093 section = 11.190 =20 inch ID

PFA-Sil 0.093 = section =20 8.950 inch ID

Paul,

I'm sending this to you "private" so as not to confuse everyone = with a=20 bunch of dimensions that may, or may not, turn out to be = correct. I=20 spoke with Jeff today thinking that he would be able to verify the = correct=20 sizes and he doesn't have those dimensions.

Looking through my archives, I found an old email stating that I=20 initially used the 11.340" dimension, but it turned out to be too = large and=20 I had to send it back to have it re-sized to 11.230" which worked = perfectly (didn't require stretching) and laid in the groove very = nicely.

<snip>

I=20 found my receipt from Creavy Seal Co. Unfortunately, it is only = for one=20 coolant seal, and both oil seals.

As for=20 the outer coolant seal=85 Originally I ordered a set of SIL .093 =96 = 11.340 ID=20 o-rings. These proved to be too big and I had to send them = back. =20 Note that 11.340 minus .090 is 11.230=85 the correct size. I had = given=20 them a size based on CL, not ID. So, be sure you=92re on the = same page=20 when ordering these things. After a few emails to Jeff Chrysler, = we got=20 it right on the re-order with these numbers=85 SIL .093 =96 = 11.230. These=20 fit perfectly. I can find no records for what I ordered on the = inner=20 coolant seals. Here is an email I sent to Jeff Chrysler at = Creavy Seal=20 after fit-checking the new outer coolant o-rings.

Attn: Jeff Chrysler

Hi Jeff,

The reworked TES o-rings fit perfect. = Final=20 dimension for the outer coolant o-rings is .093 x 11.230" ID. = Thank you=20 so much for all your help. I can start putting my engine back = together=20 now. I have passed this information along to Paul Lamar as = well. =20 This size should work for all 13B and 20B engines, but you may want to = verify=20 size before using it for the new Renesis engines.

Thanks again for your assistance,

Mark Steitle

The=20 information for the two oil seals are SIL .093 =96 4.680 ID, and SIL = .118 =96=20 4.330 ID.

Using your example of how to measure and calculate the = coolant=20 o-ring dimensions, I ran the numbers and came up with 11.182" for the = outer=20 coolant o-ring. Based on this info, I order based on the 11.230" = dimension for the outer o-ring. I'll let you know how it works=20 out.

All of the other dims agree with my numbers.

Thanks,

Mark
