Choice of metal for rotor seals

Post by Roberto »

I am faced with an expensive rebuild after 30k miles on a Commander and have found virtually no seals on either rotor are reusable. Graham is moly coating the side plates for me. Incidentally, 3 faces had smeared and one had not but that had not reflected less in the wear levels on that side of the rotor.Due to the exceedingly high price of a set of rotor apex, side seals and pins, I would like to ask if anyone else has commissioned some to be made independently and have they experience of better choices of material than the IKA3/S14, IKA, and IKA59 as stated in the aircooled engine manual. A local metalurgist suggest C1 5, which is an alloyed cast iron that is virtually indestructible. I am told that the Mazda RX8 never has tip seal wear. So what is their secret..??A local engineering company to me in Reading can wire cut me some new parts -labourwise it does not appear too expensive, but I need the right material. Can anyone advise me?
