Do they have outer water orings that are 1 piece like the innner ones? I'm kind of weary about splicing them.

Thanks, Ed

What inner orings are you going with? I was thinking teflon for the inners and stockers for the outers. It still comes out cheaper right?


Thanks, Ed

Would these inner water seals work for a 12a?

Yes they will work. The only differance between the 12A and 13b is the width of the housing. The diameters of both engines are the same.

Just making sure because the inners of the 12a's and 13b's have different part numbers. Looking forward to the pics!

yeah. i am too. ok the 158 is too big around and too thin. do not buy it or you will have what i have, a useless oil seal. so i ordered some more today the 247 i believe it was so i should have them the next business day.

is anyone familiar with mcmaster carrs return policy? i cant seem to find it on their website.

but on a positive not. the other ones work



cost:
40$ for inner water seals. (4)
11.70 for outer oil control rings (1 bag of 5)
11.52 for inner (1 bag of 5)

shipping for next fedex priority is something like 14$

and the outer water seal can be had from mazdatrix for something like 7 a piece (not worth the time of putting them together)

Try that with the stock ones! The ones from McMaster-Carr are the EXACT same ones sold by Hayes. Hayes wants $100 a set. McMaster-Carr wants $10 apiece ($40 total) for them. Hayes has to make a buck somehow. Wish I'd have know about McMaster-Carr earlier. FWIW do not under any circumstances use the environmentally safe (orange or blue) antifreeze with the teflon/silicone seals. They literally dissolve in a matter of seconds! Stick to the good old fashioned Prestone type.
Ah, so these have silicone, the weak link. PTFE is not affected.

Thanks for the #'s. Quick question though. Are these numbers for both 12A's and 13B's? The reason I aske is because I'm building a 4port using 83 12A irons with an 85 13B rotors and housings.

Thanks, Ed

the inner oil control rings are easy to get in (dip them in motor oil and tap them in with a hammer) the outters i got (with the numbers posted will not fit. they are wayyy to big. i tried to bash them in there with a hammer and nothing.
