[Engine] NEW CAMBELT PROBLEMS.

[THE BADGE]

Hi Folks,
I've just fitted a new cambelt to my 1.9 diesel DW8 engine,
good news is it runs, but it's rather noisy - knocking noise, I locked the Flywheel, Camshaft & Injector Pump & made sure all slack was taken up, I had the Cam & Injector Pump sprockets rotated clockwise as explained in the Haynes manual, something's not quite right, should I take the belt off & start again, or would moving the Injector Pump through its elongated slots make any difference ?

[THE BADGE]

I need POLAR to answer this.

Start again definitely !

Check and double check / read and re read .... don't assume / make assumptions.

Did it knock before ?

[THE BADGE]

Didn't knock before,
was a very smooth motor, the auxillary belt shredded & worked it's way into cambelt,
hence the replacement.
I will take off & try again tomorrow, probably one tooth out on the timing.

Thanks for your reply.

Good luck with it hope it comes good.

At least the 1.9 is a straightforward engine to do a belt on and you'll have all the tools to hand.

Hi sorry im late with my reply badge but been rough as you get the picture.

geoff has already said what i would have said.

[THE BADGE]

No worries mate,
hope you're feeling better soon.

When I changed the belt I couldn't find the timing mark on the pump body, so I scribed  a line into the hub & pump body,
now I'm thinking this could be wrong - had the old belt jumped a tooth or more ?
The timing mark/hole for the Camshaft is about a 2 o'clock position, but I'm damned if I can find the one for the injector pump, any help is a lot of help.

The locking pin for the injection pump looks to be around the 1 o'clock position in the diagrams I've seen.

Hi - double check the tensioner on the cambelt. I had a similar sound experience on an 8 valve Escort after replacing the cambelt - turns out I had failed to correctly tighten the belt tensioner and the tension pulley mechanism was moving about under the cover (how the belt never skipped a couple of teeth I'll never know).
