Pre-assembly inspections
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.
NOTICE: Protect machined surfaces while you clean the parts. Failure to do so may result in
equipment damage.
Replacement guidelines
Casing check and replacement
Inspect the casing for cracks and excessive wear or pitting. Thoroughly clean gasket surfaces and alignment
fits in order to remove rust and debris.
Repair or replace the casing if you notice any of these conditions:
• Localized wear or grooving that is greater than 1/8 in. (3.2 mm) deep
• Pitting that is greater than 1/8 in. (3.2 mm) deep
• Irregularities in the casing-gasket seat surface
