Use an arbor press and a piece of pipe or sleeve with an outside diameter that is slightly smaller than
the diameter of the bowl or lineshaft bearing housing bore.
2. Remove the suction bell bearing by setting the suction bell in a lathe and machining the bearing off.
The suction bell bearing can also be removed using bearing pullers to pull the bearings out.
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.
Impeller replacement
This table shows the criteria for replacing the impeller:
Impeller parts
When to replace
Impeller vanes
• When grooved deeper than 1/16 in. (1.6 mm),
or
• When worn evenly more than 1/32 in. (0.8 mm)
Vane edges
When you see cracks, pitting, or corrosion damage
Keyway and bores
When you see damage
Gaskets, O-rings, and seats replacement
• Replace all gaskets and O-rings at each overhaul and disassembly.
• Inspect the seats. They must be smooth and free of physical defects.
In order to repair worn seats, skin cut them in a lathe while you maintain dimensional relationships
with other surfaces.
• Replace parts if the seats are defective.
Bearing retainer check
Check the bearing retainer for deformation and wear.
Mechanical seal checks
On pumps equipped with a mechanical seal, check that the shaft or sleeve is free of pits, burrs, or sharp
edges in order to prevent cutting or improper sealing of the seal O-rings. Remove any burrs and sharp
edges by polishing with a fine emery cloth.
Impeller and bowl checks
Visually check impellers and bowls for cracks and pitting. Check all bowl bearings for excessive wear and
corrosion.
