Thanks BB. I bit the bullet and got a puller from toolmart. Got the bearing out easy with that. I used some old Brown Hammerite I've had in the shed for at least 15 years on that rear roller. I also used it for the inside of the chain cover. It doesn't look too bad against the green.
I've also had a bit of a win. Managed to secure a matching edger in exchange for some firewood I need to get rid of. The motor runs, all I can find wrong with it is a seized up throttle cable and the drive pulley has come adrift (see photo). Is that grub screw all that secures it?
