I have sprung a leak from the water pump shaft seal. The engine serial number indicates it is a ’48. I have the fan and the water pump off of the engine but can not separate the fan belt pulley from the water pump shaft. I have tried all the usual tricks, soaking it with penetrating oil, heating the boss on the pulley, and two different gear pullers. The first started to bend the outside rim of the pulley, the second attached to the fan mounting screw holes started to bend the center section of the pulley. Still the pulley boss will not slide off of the water pump shaft.
What am I massing?? Are there other tricks?
