Hi all, I am struggling to remove a powevalve actuator bearing from my clutch cover. The bearing seems slightly gritty to me and its the last thing to sort before running the rebuilt engine. I've tried heating several times it just doesn't seem to be going anywhere. I've got a few questions; * What sort of temprature do you normally heat a clutch cover or the maximum without damaging anything? * What are the chances of one of these bearings going? If it should fail what sort of damage is likely to occur, as the bearing on the crankcase side of the actuator has the same 'gritty' feel. * Also Has any body renewed the water pump shaft 'o' rings ? It says on parts diagrams that theres a 6mm and a 8.8mm, my spare one has only one and the 6mm o ring cant seem to get it fit over shaft Any input appreciated.
