Note: The front bearing on the charge pump uses
engine oil for lubrication. It must be kept extremely
clean. Make sure to shield it as well as the opening to
the engine from dirt or debris while disassembled.
The gasket that seals the pump to the engine housing
should be replaced whenever the charge pump is
removed and installed to prevent oil leaks and or
dirt/debris from entering the engine during operation
