Manual Extract: Water Pump Inspection

Ensure the longevity and efficiency of your water pump with careful inspection during maintenance. Follow these key steps:

Key Features

• Thorough Cleaning: With the water pump completely disassembled, every component should be cleaned and checked for wear, cracks, and burrs.
• Component Inspection: Inspect all parts carefully and replace any that show signs of wear or damage.

Benefits

• Enhanced Performance: Regular inspection and maintenance can prevent failures and extend the life of your water pump.
• Safety Assurance: Identifying and replacing worn components reduces the risk of mechanical failure.

Usage Recommendations

• Ball Bearings: Inspect for any nicks, burrs, or grooves that may lead to binding or wear. Replace if damaged.
• Pump Seal: Always replace the pump seal whenever the water pump is disassembled.
• Bushing: If equipped, check for wear, nicks, grooves, and burrs. Ensure the inside diameter is between .874″ and .875″ with a clearance of .0015″ to .004″ between the bushing and shaft.
• Pump Shaft: Look for nicks, grooves, and burrs. The diameter at the bushing contact point should be .8710″ to .8725″. Replace if any damage is found.
• Impeller: Examine for cracks, damaged vanes, and smoothness at the seal contact area and replace if necessary.

Note: Pumps with two bearings have a seat in the impeller (part 13) where the shaft seal resides, which is replaceable if needed.
