yd22 vacuum pump...

Hi chaps.

I have a yd22 and it has had a new vacuum pump but not been sealed properly by the previous owner/fitter.

How can i get it off to reseal it properly. Just pumps out oil

I can get it off undoing the 3 bolts etc but it only comes off 5mm :/

Googled it has a chain etc behind it.

Anyone know how to change/remove one?

Thanks stu

All sorted and downloaded the fsm, cheers ed
