trimming standard apex seals, third gen?
#1
I was assembling third gen motor this weekend. All parts are standard from Mazda.New rotorhouses as well.
When I mesured the length of the Apex it is 80,10-80,12 mm length. (the sidepiece is glued to the long part of the apex)
The rotor housing is (where its thinnest) 80,01mm.
The manual says the seals should be 0,10+-0,02 mm shorter than the width of the housing, but the engine builders here (not many of them here in Iceland) say they have not seen this problem before.
so before I go and grind the apexes down Id like to hear from someone that has had the same "problem" and if I am to grind the seals............ are there any good ways to do it? I didnt like the one in the manual that much.
Thanks

the long piece with the corner bit glued on is 2/10 mm to long. so if I tighten the the bolts everything will become stuck during first time assembly. as I understand the manual they say the whole thing (with the two pieces glued together) are supposed to be 1/10 mm shorter than the rotorhouse. So my only option seems to be to shorten the seal.
seems a bit strange for standard parts.......

its glued together so that you can assemble the motor, once you tighten it down the glue breaks
