Re: Water Pump Removal

You didn't mention a year but sounds as if it may be pre 51. This is a typical water pump from 40-50 and there is a gasket behind the plate and one between the pump and plate. Not sure if there is significant differences in the pumps used on lower end engines before 40. The pump layout is the same on 51-4 engines but the pump differs in shape slightly to get it lower on the block and there is no front mount.
Usually the plate is attached to the pump by a couple of extra bolts and once the main bolts holding the pump to block come off the plate and pump comes out as a unit. Perhaps someone used gasket cement on the plate to block gasket and is the reason the plate is sticking.
On most engines having the center cushioned front mount the rubber has deteriorated and flattened to the point the engine needs to be jacked up slightly to access one of the pump retaining bolts. Once that bolt is out the pump and plate can be removed and replaced without any difficulty and the mount does not interfere.
There is one or two bolts with a copper washer instead of a lock washer. Those bolt holes go directly into the water jacket so be sure to get the copper washer back on them to prevent leaks.
