Adjust 300tdi pump timing without removing cover?

Recommended Posts

i think I know the answer, but worth a try.

I tried advancing the pump timing through the inspection hole at the injection pump pulley as several posts describe. it turns out I got the slotted holes aligned in a way that allows me to retard the timing, but not advance. The pump is already all the way towards the most advanced setting in the slots.

I now know I should have aligned them the other way around when installing the belt.

 

is there any way to fix this, short of removing the timing cover?

Thanks

I can't see how you can avoid taking off the timing cover  and belt to do this - you are a tooth out on the pump pulley I suspect.

If it's the holes in the pulley that are aligned wrong, then no, you won't be able to adjust it. If it's just the cover plate, you can take that off without taking off the cover.
