Timing belt question
 

Ok I got the new belt on my 5vz-fe with the tensioner. The belt has several marks on it to aid installation, L-cam, R-cam, and CR. I lined the cam marks, cover marks and the belt marks up. After spinning the crank several times to bring the L-cam and R-cam marks back around I discovered they were advanced by one tooth.

The crank is still at 0 and the Cams are still lining up with the marks on the cover. I think everything is fine. I turned the crank like 4 or 6 more times to bring the belt back around once, and now the belt marks are off by two teeth. The Cams and Crank still line up.

Anybody ever experience this? I'm thinking that it's the number of teeth on the belt that determines this. I just don't want some issue I may have overlooked to surface after I put everything back.

Dunno really what you're saying. Are you saying it goes out of time when you put tension?

This happens with Honduhs and probably everything else. Usually I'll just put the belt on one or two teeth off and when I put tension on it's in time. Every now and then I'll get lucky and not have to do that.

It's either skipping teeth or your crank gear is not properly matched to your cam gears. If it's gaining a tooth on the cams each time you roll it over it will end badly.

The number of teeth on the belt doesn't matter, that just determins length and therefor tension and adjustment etc etc. the ratio of teeth on the crank pulley to the cam pulleys determins how they rotate together. If that didn't change than the belt is slipping teeth.

Wait i just reread what you wrote, the crank and cams all line up on with the timing marks but the marks on the belt are different each time you roll it? That's nothing to worry about it's the number of teeth on the belt like you said.

Your good. Like above poster said, as along as the cam and crank marks line up its correct. VZ series are non-interference btw. You cant break anything with incorrect mech. timing.

Unrelated note, ive heard horror stories from some of my toyota tech friends about swaping headgaskets on early 5VZ by just unbolting the head and sliding the headgasket in :l without so much as removing the tbelt or exhaust...Scary. Apparently it pays something ridiculous like 10+hours and there are 'techs' that do it in 3. FYI.

Ok, I just thought that was weird how the cam marks on the belt are like one tooth off every 4 rotations of the crank (number of turns required for the belt to make one revolution).

But my crank and cams still line up. I just thought maybe I overlooked something.
