Hi, I have taken off the timing cover to send the inner cover to Sean Hawker to have the oil seal done prior to fitting a belt drive.1st, the oil pump compartment was full of oil I don't think thats right? 2nd, there are 3 nuts to take off, also the worm drive gear (I think) is this part of the pump? what I mean is do you remove the left hand tread nuts and take off what looks like a spring,or does it all come off together with the pump?
