hey guys long time no talk. these seals came out of a 1987 block that was clamed to be JDM. it was leaking so much water when i pulled the motor the block was full to the exsaust port. has anyone ever seen these apex seals before. this is my 5th teardown and i have never sean anything like this! i cant even find them on atkins

no these are not broken all 6 are the same and yes the housings are sqrewed!

 

Wow those corner pieces are strange, I bet they ate up the sides of the housings.

 

see now the corners where ok it was the acualy faces of the housings that where messed up because that corner peace acualy completes the apex seal. the first piece does not go right accross it needs the smaller ones to make it all the way accross the slot of the rotor. therefore your left with a very uneven wear pattern and very bad ridges ill have to make another thread. the whole motor was a disaster inside. deffinatly home built!

was there only 1 spring under each apex?

 

wouldn't that be the same thing as a cracked apex seal? I might not be the smartest rotary guy out there but that design just looks bad.

 

No. Pretty much all of the seals sold are multi piece. There used to be 3 piece from Mazda. The only odd thing on here is he seems to be missing the short springs. The seals also aren't stepped. Normally when installing the short spring, that step will let you feel when it is in all of the way.

yes there was only one spring. if you notice on all the 2nd gen seals i have seen there is 2 slots for one small spring and one big spring. these are only slotted for one large spring as u see in the pic. its funny it says it will save your housing i will have to take a pic. its worse then a motor with a blown apex seal and this one still have 45 psi of compression on all faces

 

What I'm refering to is the location of the corner piece of the apex seal. Usually that piece starts at the very end of the apex seal, not on the apex seal face that makes contact with the housings. I've seen my fair share of apex seals

 

Gotcha. I didn't even pay attention to that part. That does look odd.

so the link posted those are the seals because the way your talking im confused

 

The ones you have pictured are not the Atkins seals. You have something else.

 

haha so back to square 1 then. i will go snap a pic of the seals in the rotors to show the size of the "corner" seal

 

they look like Hurley seals, old

 

The original RA seals were single spring and had a very wide corner piece, although I don't remember it being THAT wide.
