Good O. I understand the problem - but how can I clean off the crud when there is no way of getting to it? Even if I made a puller I wouldn't feel happy about using it on the Aluminium alloy cover. I made one to help with the removal of the fly wheel, but it is a much more robust device even though it also is alloy. Also, the crank shaft is not in the centre of the crank case cover so the force on the sides would be uneven.
Any suggestions??
Also, there are two other replies: how do I access them?
