Remove the drain plug from the bearing housing. Drain the lubricant then clean,
inspect and reinsert the drain plug.
Disconnect the pump hardware before sliding the bearing cap and oil seal from the
shaft. Push the oil seal from the bearing cap after removing its gasket.
After placing a block of wood against the shaft at the end of the impeller, tap the
shaft and bearings from the bearing housing.
Press or pull the oil seals from the bearing housing.
Once the shaft and bearing are removed, clean and inspect the bearings that are still
in place. Follow these instructions: soak a soft cloth in cleaning solvent and
thoroughly wipe down the bearing housing, the shaft, and all the component parts
with the exception of the bearings. Check all parts for damage or wear and replace
any that are defective.
IT IS RECOMMENDED THAT THE BEARING BE CLEANED AND INSPECTED IN PLACE
TO PREVENT DAMAGE DURING REMOVAL FROM THE SHAFT. WE HIGHLY
RECOMMEND REPLACEMENT OF THE BEARINGS ANYTIME THE SHAFT AND
BEARINGS ARE REMOVED.
BEFORE USING ANY CLEANING SOLVENTS CAREFULLY READ AND FOLLOW ALL
PRECAUTIONS PRINTED ON THE SOLVENT CONTAINER. CLEANING SOLVENTS ARE
KNOWN TO BE TOXIC AND FLAMMABLE AND ARE ONLY TO BE USED IN WELL-
VENTILATED AREAS AWAY FROM EXCESSIVE HEAT, SPARKS, AND FLAMES.
Use fresh cleaning solvent, thoroughly clean bearings. To dry them, use compress,
filtered air then lubricate with light oil.
BEARINGS MUST BE KEPT IN AN ENVIRONMENT THAT IS FREE OF ALL DIRT AND
FOREIGN MATERIAL. FAILURE TO DO SO WILL RESULT IN A SHORTER BEARING
LIFE. THE BEARINGS SHOULD NEVER BE SPUN DRY AS THIS MAY SCRATCH THE
BALLS OR RACES AND WILL CAUSE PREMATURE BEARING FAILURE.
