Guidelines
Before you assemble the pump parts, make sure you follow these guidelines:
• Inspect the pump parts according to the information in these pre-assembly topics before
you reassemble your pump. Replace any part that does not meet the required criteria.
• Make sure that the parts are clean. Clean the pump parts in solvent in order to remove oil,
grease, and dirt.

Protect machined surfaces while cleaning the parts. Failure to do so may result in
equipment damage.
