hello all,

Im in the process of rebuilding a 13b and am trying to verify the correct way of positioning the rotors so I can line up my timing marks, and the matching marks on the CAS. So everything lines up.

all my guides and other info says just line up the rotors in " one of these postions" and it says either pointing to top or bottom of the housings {opposite 180 degree positions of the front and rear rotors of course}

Does it really matter if the front or rear rotor is top or bottom? or is there a preferred way of doing it beyond this rough outline?

 

point the front one up, and the back one down. Easy as that.

I dont think it really matters which one goes which direction,(someone correct me if I'm wrong), as long as on in place correctly, and the other is 180 degrees off. You dont need to worry about the pulley marks lining up, they only go in one direction. Its impossible to mix that up.

 

thanks for the reply. Good luck with your new rebuild and I read in your other post that its up and running.

 

I am not sure it matters much. I thought the same thing but the video just sai point this one this way and that one that way and off you go. I feel the if there was a timing issue there would be marks on the stationary gears that lined up with the rotors.

I just chalked it up to it has to do with the E-shaft

Correct me if I am wrong maybe I'll have to take my motor apart and change things. Let me know if you are still having trouble over the weekend. I'll plug the video in and tell you exactly what they said to do.

 

Actually, it's impossible to screw up, as Syklone says.

After you have your engine assembled (during assembly they'll only go in one way, 180 degrees apart), and you get your pulleys on and such, you're going to turn it a couple of times by hand to make sure that everything is seated properly anyway..

You don't have to worry about timing until you go to put your CAS (crank angle sensor) in.. and then it's simple. rotate the engine until the timing marks are lined up, the timing marks are on the main pulley, there's alittle pin that sticks out of the front water pump housing, and then on the CAS, the gear down at the bottom has a little circle in it. Rotate this until it lines up with the arrow on the CAS housing, line up the cas in the hole and push it straight down. The worst thing that can happen is that the CAS gear will rotate one tooth forward or one tooth back, so be careful when you're putting the CAS in.

That's it. It really is impossible to screw up

 

yea, that is the instructions I followed but it just seems that those Rotors need to oriented somehow other than an eyeball placement of 2:00 o'clock and 6:00 o'clock. The only thing said was make sure it is not on the Coolant seal and that it is centered when putting the housing on. Just too plain for me.

 

Man I cant wait till I have the space to rebuild an engine....I really want to do this!

Dang apartment living!

 

they only fit in one way. there is no eyeballing about it. you cant mess up, because they wont fit any other way.

soo much better than a ******* timing belt...lol

pat

 

I followed the instructions on the video so I they went together correctly. I guess if I tried to put it in incorrectly I would have seen that there is only one way....the correct way. The video solved the enigma for me.

C'mon x'treme. Buy the case of beer and have your homeys help you yank it out by hand. I know in apts there are lotsa guys with a free Saturday. Oh the apartment life. I used to have so many friends form those places. My nice neighborhood has nothing like that. There is only one 19 yo kid that comes over to watch/help with my motor. He's a Honda Head, but I am converting him.
