1G I cannot seem to get it timed correctly

[jonseclipsegs]

I am in the process of revamping my 91 gsx. However, I am having problems with the timing belt. I have been trying to follow the instructions on the tech section of the site, but I cannot seem to get it timed. Every single time I try to tension everything, either my exhaust camgear is off, or my crankshaft mark isnt correctly lined up. Does anyone have any ole dsm tricks to lock these in place? Or an easier way to do it? Thanks.

When you put the belt on, make sure that it's as tight as it can get, or back one of the gears off.
Point being so when the dots line up, its where it should be.
If that doesnt work you can always use something to jam between the gears, there is something made that fits in the cam gear teeth, not sure where to buy it.

Hope this helps!


btw, when you get the belt on, use zipties to hold it to the cam gears.

Set things up on the crank the correct way, then, when you set up the cams, set each so that it looks like it will be off a tooth. Then when you tension, things should line up. There's a vfaq on it that tells you exactly how to do it!

Good luck!

I do what staticbrainwash is talking about.

I start with all the timing marks lined up and put the belt on the exhaust cam and clip it.

I roll the intake cam sprocket backward about half a tooth and pull the belt as tight as I can without moving the exhaust cam to fit the belt onto the intake sprocket before clipping it to the sprocket. Then rotate the intake cam forward to make sure the timing marks on the cams still line up and that I can't go past the marks. (

Now I know that the exhaust and intake cams are exactly right with no slack so put the belt around the idler pulley and like before, turn the oil pump sprocket back half a tooth. Again pull the belt as tight as you can and fit it onto the oil pump sprocket. Rotate it forward as far as it will go and check the marks again. (This make sure there is no slack between the cams and the oil pump)

Continue the same process for the crank and then adjust the tensioner pulley to take up the slack between the crank and exhaust cam. Nothing should move at that point since you have made sure there wasn't any slack from extra teeth of belt between each sprocket. If things don't line up go back and fix it.

All you have to do then is preload the belt with the tensioner pulley and make sure the auto-tensioner is correctly set.
