The Atkins Video says " the pointed end of the apex seals should point to the rear of each rotor'. Then the video shows the apex seals being installed with pointed end facing the none geared side on both rotors. Isn't the front face on rotor the geared end and the other rotor the non geared end.


thanks.....ashley

Front rotor gear down, rear rotor gear up. I should specify. This is per the way the atkins video assembles it (as well as most everyone) assembling from the front to the rear, with the rear facing UP in the air on the engine stand.

Basically, when installing the rotor you just have to put it in (as just specified) and have the part of the apex seal where the corner piece is put in facing UP. It is easiest if you put in the corner piece after the rotor is in, so you just put the larger piece of it in the rotor, drop the rotor in, and then put in the corner piece after the rotor is in there.

Hope that makes sense.

So, the small piece will face up when installing the rotors. I think that is what the Atkins Video says but not what they show. The guy in the video has both rotors sitting with the geared sides of both rotors facing left. Then he shows the apex seals being placed with the angled side facing right, on both rotors. Right?

The RA video shows the rotor allready inside the housing when you start. If your front Iron is on the stand facing up (you'll be putting the front Irond together first then the middle Iron then the rear housing etc.) You put the housing on lower the rotor in place. Then you pull the side seal and insert the apex seal with the Corner toward the top or rear or away from the Stationary gear on the front Iron. ( could I say that another way....No). After thapex is in you slide the small spring in and then the large spring in and you'll hear the small spring "click" into place as the large spring is being inserted.

Luckily the rear rotor is exactly the same as both the corners face the flywheel. If you have the new apex seals they are all one piece until the get into place and when you turn the motor over they crack loose and become......well I am not sure what happens.

Are you doing your own motor Ash??? Way cool

That would be wrong.......I think.

The front rotor is going to have the corner peices facing away from the stationary gear. The rear rotor is going to have the coner piece facing the stationary gear.

Is that what you said??

A friend help take the motor out of the car. I took it apart. I'm trying to put it back together and then I'll have help putting it back in the car. I like mechanical stuff. I started out to be a mechanical engineer and then I switched to pre-med after my second year. Gonna be an MD now, probably, hopefully, maybe. No, really, I'm a 4.0 student so someday I'll be an MD.

Back to the 7. Yea, thats what I thought the video was saying. The little corner piece away from the stationary gear, But, I don't think thats what the video shows in the section that shows how to install the apex seals.

After the rotor is placed in the motor and the corner section is installed, does the corner section "click" into place? Is this going to be a no brainer when I actually get that far.?

thanks........ash

Well you said the corner piece away from the stationary gear, but you didn't say for the front only. The rear corner seal is going to be next to the stationary gear.

The "click" that I described was the smaller of two springs clicking into place. The corner seal POP as the break loose later in the assembly procedure. actually when you spin the motor for the first time after it has been asembled. You'll hear "pop" it when you get to the point of working with the e-shaft 19mm, the oil pump and the Flywheel.

Seems I an the only one chiming in here so help me out.
When my motor came apart the apex was in three pieces. Main part, corner seal and teh bottom part. The new ones from Mazda were all in one piece with a score or slice cut where the corner seal will break apart. Is that what you have???

Back to the "Click" If you have your apex seal in the rotor and the rotor in the housing and the housing on the front Iron( was that clear?) WHEN you try to put the little spring in you can only slide it in so far because of the configuration that your working with. You could get a small screwdriver and push it in all the way but it is not necassary becuase of the next step. After the small spring is inserted as far as you can push it (without going into the rotor) take the larger spring and start inserting it into the slot. It will get tight and "grab" the smaller spring, you'll be pusing both for a short period untill you hear the small spring "Click" into its proper position. It is a definate "click" and yes once you've done one you might say it is a no brainer. Replace the corner seal and corner plug and your done with that one.

Thats the front rotor, now pretend you put the middle plate on and your rear housing and you out your rear rotor in place. The gear sid is up on the rear. SSOOO the corner apex seals are on the gear side of that rotor......always facing the flywheel.

Would one of the professors please check my work b4 Ashley goes off and follows my wrong advise!!!!!! Please!!!

Nobody else??

OK. Just talking about the 2 piece apex seals, the long main section and the shorter end section. On the first rotor to be installed, the front rotor, does the small end section point up, or is it pointed down toward the front of the engine.? Then, on the rear most rotor, the last rotor being installed, does the small end apex seal end up being installed last? The Akins video shows both of the small end sections of the apex seals being installed next to the stationary gears but the commentary says that the end pieces should face the rear of the engine.

Sorry for the bad drawings, laptop trackpoint is no replacement for a tablet.

But as you can see in the picture, that is how all the apex seals should be orientated in relation to the engine. Corner peices on the flywheel side of the rotor. Hope that answers yoru question

The corner piece always goes closest to the the rear of the engine, unless you have a half-bridgeport.

Take a look at my engine build thread in the archives.
