H. REASSEMBLING THE TWO-PIECE BEARING HOUSING
Replace and lubricate the O-ring. Place the inner bearing housing half into the outer
bearing housing half and install the four bolts and lock washers (See Figure 5).
Torque the bolts to 67 lb-ft for dry threads and 40 lb-ft for lubricated threads.
I. REASSEMBLING & INSTALLATING THE SHAFT & BEARING
Soak a soft cloth in cleaning solvent and wipe down the bearing housing, the shaft,
and all component parts with the exception of the bearings. Check all parts for
damage or wear and replace any that are defective.
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.
Carefully inspect the pump shaft for nicks or scratches, any distortion, or for thread
damage on the impeller end. Use a fine file or emery cloth to remove small nicks
and burrs. Replace the old shaft if it is damaged or defective.
Refer to Figure 6 for correct positioning of the inboard oil seals in the bearing
housing bore with the lip positioned as shown in the diagram. Push the oil seal into
the housing until the face is exactly even with the counterbored surface closest to
you during the installation.
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.
PUSH AGAINST THE OUTER RACE DURING INSTALLATION OF THE BEARINGS INTO
THE BEARING BORE. NEVER STRIKE THE BALL CAGE OR BALLS.
