max, where you been! need an update!

Tracy Crook

Haven't heard from Max in the past few days and still have not seen his seals yet but here's an update on the RA seals.

We recently had a second report of a problem with our seals so we went into emergency mode to investigate any possible problem. Between the info that Max and the other report, and some in-house testing, we found the source of an isolated problem in our production processes that affected some seals during the period around 8-03 to 12-03. Very few of the thousands of seals manufactured were affected.

Manufacturers usually do not publicize this type of problem due to the adverse publicity that inevitably results but we have always been up front about any problems with our aviation products and will do the same with the apex seals. If you want to read the details of our investigation, go to the Apex Seal page on our website. www.rotaryaviation.com

You. Guys. Rock.

I was planning on buying a full rebuild kit from you with those seals, and this thread made me hesitant, but I'm feeling pretty damn optomistic about them after how you guys are handeling this!

Well, I feel better about my RA seals now. My engine is still apart, so I think with this update I'll give the RA seals a try in my rebuild, assuming the dimensions check out okay (and I expect that they will).

I'm with you guys, that's the best customer relation I've seen in a long time.

could you stay in one measuring standard, you've been throwing out inches and milimeters and it makes reading your posts confusing

Me too!!

The only question on my mind is should I buy new housings. I was watching the Overhaul video from RR (Great Video) and I noticed when he mentioned about the chrome flaking. My housings look to far gone.








Are all of you guy's using brand new housings?

Is it possible to find used housings in good condition?

Thank's

We have had no more reports of problems but the two reports we got lead us to a complete review of our processes and we incorporated many improvements.

We never did get to see any of the seals that had problems but due to this exercise, the product is better than ever. We will continue to refine our apex seals and welcome any and all reports regarding them.

In aircraft applications we run the engines normally aspirated at full throttle continuously but we don't get much experience with high boost. Several engine builders are running our seals with up to 35 - 40 PSI of boost but to get some first hand experience, we are building up a 3rd gen RX-7 with our seals and plan to flog it on a chassis dyno (after a normal break-in period). We will post the results on the website as they come in.
