Ive attempted to do a cambelt change on my astra van (99 T plate - 1.7 TD GM Engine not isuzu). Being the dumb ass that i am rushing all the time i have not locked the injection pump sprocket up before taking the belt off.
I know have a car that is either out of time or just knackered in general. Both bottom and top are at top dead centre (TDC) but the injection pump sprocket is well out.
My theory is is that if i remove the pump sprocket and put it back to where i can lock the pin in, whilst the others are at TDC, then would this fix my problem?
The only reason i am hesistating to do so is because when i try to adjust the pump sprocket it seems to be on a spring mechanism and i dont want to totally knacker my van if there is another way around it.
What would happen if i did take the sprocket off and adjust it etc? or is there another way to adjust it. I have tried to manually move the sprocket and lock it in place but i can not seem to find the hole behind the sprocket to lock the pin into.
Any hep would be gratefully recieved.
