Timing Belt Marks

[JAP63]

what doesnt look right is the cam nothes...
the exhaust cam notch is sitting a liitle higher than the intake

theyre not dead level......does that mean my cams are out?

Bingo, you need to rotate the exhaust cam clockwise by one tooth more then rotate the engine by hand again and it all should line up.

so that would be my mechanics fault??? :evil:

whats the best way of rotating it?

lock the belt to the intake side cam and take the belt off the exh came and put a spanenr on the nut,turn the exh cam till the marks are level?? then put the belt back on???

Yep, more proof of why to not let your mechanic anywhere near it again.

Lock the belt to the intake cam and wedge the belt to the crank sprocket so they can't slip.

Insert special tool "A" (threaded rod), push the hydraulic tensioner in. This should hopefully release enough tension off the belt to allow you to put a ring spanner on the cam gear and carefully work the belt enough to let you rotate the cam clockwise one tooth.

If there is not enough slop in the belt, then you will have to loosen the nut that holds the eccentric bearing in place to release more tension.

wedge the belt to the crank sprocket so they can't slip.

when u say wedge the belt,do you mean wedge the sprocket?

will the intake sprocket want to turn once i release the belt tension and try and move the exh cam?

and lastly,if my exh cam was a tooth higher than the intake..would that make it retarded on advanced??

The crank sprocket won't turn by itself (as long as the spark plugs are out and there is not compression in any of the cylinders). Wedge the belt to the crank sprocket so that the belt can't slip and stuff up most of your hard work when you release the tension from the belt.

I can't remember if the intake cam sprocket will want to turn when you release the belt tension, lock it in place if you can just for good measure and lock the belt to the cam gear so that it can't jump.

I'm not certain about your last question but if the mark on the right hand side of the exhaust cam gear is higher (ie you need to rotate it clockwise to correct it, I would think that it was retarded, and you need to advance it to correct it.

Sweet..thanks
I might find that the cars goes better after that,maybe...
Anyway i think what was throwing me off so much yesterday was that i was puting whiteout marks on the belt and expecting that mark to be back at the same spot after six revolutions..that cant happen though right?

Because the belt wont neccesarilly do one revolution for six of the motor,and it might not even have the same particular tooth engaged either..i think

Anyway..as long as the three bottom marks are facing the timing points and the cams are dead level at 3 and 9 0clock with the dowel pins up i should be fine........what the VFAQ says anyway....
thanks.

Yeh, I wouldn't be too worried about the whiteout marks, it might take 72 revolutions before they all line up again (you could work it out if you counted the number of teeth on the crank sprocket and the number of teeth on the belt).

I don't know if advancing or retarding the exhaust cam will change the power or the power delivery but I think Aldo is playing around with this at the moment. If someone has the specs for the std cams, I could plug them into and engine analyser program and see what effect it would have.

Nother question Rob..the tutorial isnt over......

When i tighten the centre bolt on the eccentric cam pulley it wants to put the cam on hard,further than where i positioned it by pushing up with the drill bit in the little hole...

Will this work put as being bad? the belt seems really tight

the holes are around the top now with the most forward hole being at around 1 oclock..

leave it you reckon?
