If your timing marks was lined up when you took the belt off, you'll be fine. Read more info by clicking here.

Ok thanks. The crank is 1 tooth counterclock wise right now.

 

Ok I finally got the belt to where I thought it would be right. Got the crank lined up and the cams on the back head and the intake on the front perfect. But the exhaust is half a tooth off. I didnt think you could be less than a tooth off. I didnt pull the pin yet in the tensioner if that matters. How do I fix it or would it be ok?

 

Set the pretension with the tensioner pulley using the special tool and to pull all of the slack toward the tensioner side of the engine and see if everything lines up. Everything should be dead on- the only reason it wouldn't (without any machine work) is if there's slack on the belt anywhere but the tensioner side.

Looks in time now. I didnt have the VC bolted down...

 

From the sound of things you are doing this wrong. When you pull the grenade pin on the tensioner the rod should not extend or contract at all. You should still be able to put the pin in after 5 mins without forcing it. Do you have a copy of the timing page from the manual?

 

You didnt pull the pin on the tensioner?? I dont see it in the pic! And as Alex pointed out it looks like the tensioner is extended much too far from what it should look like if you did it right.

Your 1/2 tooth off can be from the belt not being tensioned properly, BUT your timing does seem to be accurate.

On that mark where you did the sharpie to match the tooth with the diamond.... Look on the backside of the cam sprocket. There are marks there too. They are MUCH easier to see than the others on the rear head.

Ya I have a manual. I just took the pin out a few mins ago. I didnt in the pic though you can see the pin in the bottem pic. The pin slides in and out easily.



It dont look half a tooth off now it looks dead on after I tightened on VC down. Hmm.. Didnt know there was marks on the backside. I did sharpie it down the sprocket though.

 

On the six timing belt installs I have done the rear bank exhaust cam has always been off by 1/4 or 1/2 tooth until the section in the shop manual where it says to rotate the crank half a rotation CCW then back CW and check the marks. The proper tension in the belt corrects this issue as speedy25 said.

edit:

Check out this .pdf straight from the shop manual. It includes instructions on the timing belt install.

Cool, if the pin still slides in and out then you're doing it right.

Congrats on a timing belt install.

Try giving the thing 2 full turns CW and make sure the timing marks all line up. If they do, you're good to go!

 

Thanks it was a hard. I didnt think I would ever get it done.
