Can anyone tell me how to remove the oil pump drive gear from the shaft? The manual is fairly casual on the issue. I have read both "I Am Carbon" & "Airwolfe's" excellent thread's on this procedure plus a number of other posts dealing with the process but, according to all, the worm drive and this gear drive should just lift off. I have removed the woodruff key and the drive spins and wobbles freely on the shaft but it won't slide over the chrome shaft end shown in the pics. I have pried, levered, heated and tapped to no avail. Could the shaft be deformed? Is it a wheel puller job? I would have left the bloody thing alone but I found debris in the filters and wanted to check the condition of the pump rotors.
