before we start, yes i did a search, i found alot about how to FIND TDC, how to time for super chargers... ect.

My question is how do you put the CAS\DIS in the correct place.
Haynes states that you put the leading mark on the needle, put the little dot on the gear of the CAS with the mark, and drop it in. but when we finally go the car to start it was WAY off. i had to remove the bolt and retart (counter clockwise) the CAS quite a bit for it to run smooth.
when it was in the way i THOUGHT was right, it was popping, and backfireing like crazy.

Please someone clear this up, i need to get this car running ASAP!

also for the people that are going to tell me that i need to pull it out and try again, well i have done it 5 times. every single time i line up the dot with the mark on the CAS\DIS and put it in when the right timing mark is lined up with the needle.

Thanks guys!

1. Do exactly what the Haynes says to do....but..

2. Prior to doing that, remove the black top cover that is held with two small screws.

3. Now align the marks on the pulley then align the marks on the bottom of the cas like the Haynes says.

4. Before installing the cas, look in the top of the cas at the gears and their relationship to a fix point/place in the cas.

5. Now stab the cas. Note how the gear in relationship to the gear in the top of the cas ...has moved as you installed the cas.

6. Now use common sense and rotate the cas body til the gear and the fixed place align once more. If the body will not rotate enough one way or the other......then restab the cas but turn the cas rotating part so it will engage a different gear in the internals of the engine. Make sense???????

yes it makes sence,

I did forget to mention that i have removed the black cover, and yes when i install it the gears cause it to turn, but i figured that Haynes/mazda took this into consideration when creating that dot. so accually when first installing it the dot should be off one tooth or so? so that when it is put in it aligns?

Attached... http://www.teamfc3s.org/forum/showth...threadid=29846 is a jpg of a cas. The cas gears in relationship to the two black decives will look similar to this attached jpg. I pulled it out of the car and put it on top of a scanner....so don't look or expect to see any attach bolt/nut. I can pull the cas......spin the engine with the starter....realign the timing marks on the pulley......restab the cas so it looks like that jpg.....and put a timing light on the car and it will not be off as much as five degrees. I like to think it closer to spot on than five degrees. Done for the day.

EDIT: The cas gear aligns/mates with a similar gear on the eccentric shaft. It's normal for the cas gear to want to turn. If you don't get it right the first time then reinstall it with the cas gear turned just a touch in the most favorable direction. That you have to figure out for yourself. When your through the gears should look like the ones in my jpg AND the hold down bolt/nut should also be in the cas slot so you can tighten it down. If the slot is to far one way or the other .....then you have to restab the cas with the gear turned a bit one way or the other just a tooth or so.

ok, after messing with it a bit, i discovered that if i remove the bolt and move the CAS clockwise untill the "lock" just about hits the altinator belt, i can get the car to run smooth. but of course as far as the timming marks are concerned, I AM WAY OFF TIMMED. but it sure does not sound like its off. and when i put it back on the "correct marks, it starts to back fire REAL bad, and even not run.

so it sounds to me like the timing marks on the pully are off.... But how? the pully only goes on one way.

I don't get it. any help would be great!

P.S. for a temp fix, i removed the CAS and "jumped teeth, so that the CAS can be locked down in a good running spot, but this means that i still cant time the car as the marks are way way off.

Thanks again!

Are you sure you're aligning the correct marks on the CAS shaft? Don't get fooled by any casting marks.

If it makes you feel any better, after my rebuild I had to time it by ear to get her running smooth also, she was no where near (probably about 10* off) the marks. I slowly tweaked it back while she broke in...
