Rotary Car Club - View Single Post - An argument for tracking used seal location

there are two ideas here. the first is simple, its a good idea to keep a seal that is worn into its groove, in the same groove if it isn't replaced. just like its a good idea to put a bearing back onto the same journal etc etc.

the second thing, is that if you're not using new rotors the side seal grooves are probably different lengths. the rotors are actually kind of flexible, and they do get bent here and there. so if say you fit a side side to groove #1, to a clearance of 0.0002" if you move it to groove #6 on the other side it might have a clearance of 0.10".

also it seems like the side seals wear the quickest, AND their role in sealing, is pretty critical, so you want them to be on the tight side of mazda's spec. 0.006" might be in spec, but just barely, and that's no good.
