Yes, but I don't like 3-piece seals. For the cost of new ones, reusing seems like a good idea. Be careful that the seals are not warped.

I never had any trouble reusing springs, look at the apex seals springs closely, they wear on the ends and it is not always obvious.

If they didn't get bent while removing (bends the weak direction are ok, but not in the strong direction - it will hurt the sealing surface).

Check how much of the edge is shiny (I think there is a spec in the FSM). Replace the O-rings for sure.

There is no reason to replace good corner seals, just make sure that they aren't cracked.

That depends on how they fit the eccentric shaft. you will have to mic them and verify that the oil film thickness is within spec. You will want to be ultra careful when pressing them out to keep them straight so that they don't deform.

care of it.

Up to you, I was told my a good friend whose porting ability I respect that if you think that bigger is always better - leave the exhaust port alone.

I know this thread is useless without pics. I'll get some I promise. I have to
clean things up this weekend and then take the pics.

Cool, please do.

Wow! Quick reply. Thanks.

These are 2 peice seals so, all good except one of the small corner pieces
is broken.

So the oil control rings are not shiny at all and I assume that means they
are fairly new and reusable?

Is there an easy or trick way to push out the bearings from the rotor? I have
a large tool for pressing out various sized ball joints for trucks maybe I can
use that. Maybe some heat would help as well.

On the porting, I also think bigger is not always better but most of the
SP exhaust looked they would cover this area. Need pics for sure so you
all can advise me on that. I think I'll do the porting but haven't decided
yet.

I think I may use the A engine eshaft since the bearings are already matched
to that eshaft. I just have to get them pressed out carefully so I can reuse
them in the B engine rotors. The A engine rear rotor is toast and I'm having to
work pretty hard to get the hard seals all out. Mostly due to the rust that
formed when it sat with the coolant in it.

How do most folks get the bearings out of the rotors?

Favorite DIY methods or tools?

I know I can take them somewhere and have them pressed out but if I
can, I want to do it myself. More fun for me
