    Ok so iv nearly finished my rebuild (just stock parts really), just trying to fit the timing belt but im scared of getting the timing wrong and ****ing up all my hard work.

    Whats a precise reliable way of; finding TDC, keeping it there and getting the timing belt on, then after that how do i know its all good?

    any help much apreciated

    thanks in advnace

    The crankshaft pulley has marks that line up to an indicator on the block- that gives you TDC for cylinder 1. The cam gears also have marks for TDC. Line them all up and pop on the timing belt. One tooth off typically won't hurt the engine on startup- you can always jump it back and you'll usually be ok.

    I thought you use the timing light to check ignition timing? Like moving the dizzy while one person tells you when it is lined up with the marks on the pulley?

    I guess what I am asking is....... say you got the timing belt slightly off how would you tell by using the timing light??

    Sorry if its a noob question.

    Duh, brain fart- you're absolutely right. I don't know what I was thinking. Just make sure that the marks all line up. :) The timing light has nothing to do with the timing belt, my oops.

    No problem man. I was just curious because I am getting ready to do the timing aswell and a little nervous. Only thing is my camshaft gear doesnt say UP any where on it.

    Also I dont understand what they mean rotate it 3 teeth to take out the slack? Does that mean slide the belt 3 teeth or what?. Sorry if I hijacked the thread I just figured this is all timing belt related why start another topic.

    No, don't slide it 3 teeth in the belt- rotate the cam gear and belt together to tighten up one side so that you can adjust the tensioner correctly. I assume that's the set of directions you were looking at.

    Yea I just didnt remember off the top of my head.. So I put the belt on with the tensioner lose and then rotate the cam and belt then tighten the tensioner.


    Thanks

    Yeah. Make absolutely sure that the belt does NOT jump a tooth when you do this. It's easy to slip it until the tensioner is tight.

    Ok I just want to confirm some thing. When I rotate the cam I am wanting the crank gear to rotate aswell right? I just wanna be 100% clear thanks alot man I really appreciate it.

    It probably has to- but you're trying to tension one side of the belt. Just move the cam gear the amount the manual says so that the belt gets tight. The crank pulley may move, but probably not nearly as much as the cam gear.

    Ok thanks..I am pretty sure I get it... Just moving it enough take the tension out not enough to affect TDC or other things.

    Thanks.
