Paul and George,
thanks for your suggestions.
When I assembled the apex seals back in the apex seal grooves , the side
seals dropped down
too easily. I doubt the splice would have withstand the force of the long
apex seal spring.

Kind regards
Thomas

"side seals"? Do you mean the side piece?

Do you have a 3 piece apex seal or a two piece seal?

There is a device called an assist piece.

Also you put the springs in after the rotor is in the housing
and the apex seals are in the slot.

Sorry Paul,
my fault. I used a false term. I mean the side pieces. I have the 2 piece apex seals as I got a Renesis engine.

I got a workshop manual from Mazdatrix.
The side pieces came off when I temporary put the seals without springs into the slots in order to
verify that the slots of the corner seals were in line with the slots of the rotor.
I will give the superglue a try.

They are not supposed to do that. Try super glue and get back to us.
Lyn Hannover has done this many many times so perhaps he has some advice.
