marks on timing belt

[BobES300]

I've been trying to get my belt on for about two hours... I have the cams and crank where they need to be but no matter what I do one (just one) of the marks on the belt is off one tooth ? Won't the tensioner make up the diff or does it need to be exact ? Also, can someone clarify the belt routing ? What the manual calls left and right seem to be the opposite of what I'm thinking. Is the rear/back (near the firewall) cam pulley the last thing I put the belt on or is it the front one ? Don't know if that makes a difference in my belt marks. I did check and I have it facing the right way.

thanks,
Bob

Forget about the marks.

Position the crank and cam pulleys where they need to be (TDC). Install the belt, rotate the crank from TDC to TDC, and check the alignment of the crank and cams (they should be at TDC).

If it doesn't line up correctly, you meesed up, and need to start all over again.

Right hand cam gear = rear one (the one near the firewall)

Left hand cam gear = front one

Rear.



By the way quit cross posting between here and the Lexus forum.

This is your 2nd warning.

If the cam gear keeps comming up about a half tooth off, put it AHEAD of the mark
