25/30 Timing Belt Fitting

[wig r31]

I need to fit my timing belt which is the 152 teeth dayco belt but not sure how many teeth to count between my timing marks so its not out by a tooth or 2

Im pretty sure I came across this info a while ago but do you think I can find it when I need it

If anyone can help it would be greatly appreciated

Don't count.

Line the exhaust cam gear up on its mark.

Line the inlet cam gear up on its mark.

Line the crank up on its mark.

Put timing belt on.

Turn crank over twice.

Check marks.

If all marks still line up where they were originally, well done, job complete.

If they do not. Take timing belt off re align everything to their marks, start again putting belt on until after two turns of the crank, all of the timing marks line up.

This is the proper way to do them.

Sweet thanks, going out to the shed now to give it a go

I'm assuming most people do not install the tensioner spring and stopper, and manually tension the cam belt.

What sort of deflection is generally seen in the belt when tensioned?

I've done mine until it feels "right" but what is generally achieved by those doing their own?

what i have found is the tensioner spring, does not work properly with the new stud location as per this SAU rb30 guide. the spring stud is in the wrong position to load the spring properly. is anyone using a different spring to achieve the correct install or drilling a new hole in the back of the tensioner housing?
