Timing belt question = 1.9dt - sweeney1987 - 27-02-2014
Right ho, so after converting from lucas to bosch the timing belt has me a bit puzzled.
Put all pins in, put on belt, and thats where problems start, the belt seems to be exactly half a tooth out between pump and cam.
Now my instinct is to remove timing bolts from pump and pull belt so cam and crank align properly, but is this the right thing to do?
Is the timing belt designed so that the cam pulls back to the correct position when the tensioner is on tension?
Or should i ignore the new bosch pullys timing, set it close to the holes and tension fully so cam and crank match perfect?

I'd take the cambelt off, and then realign the cam, crank and pulley. If the pump, crank and cam are locked into position then theoretically the engine should be timed. Then it's just a case of giving the engine 4 full rotation and checking again to see if the marks line up again.

Personally from what I'v had to do in the past free time the cam knock it back towards the bulk head half a tooth it needs. 9/10 out of ten it aligns itself up

I had this problem, car in 5th gear you should be able to move the wheel a little bit which in turn gives you the half a tooth up at the cam. Its that tiny bit of slop in the flywheel locking key, although it depends what you use to lock the fly with.

theres no problem getting belt on like that it just doesnt seem right
