With the sealplate on a level surface, impeller side down, use a wooden dowel or
other appropriate tool to press the backside of the stationary seat until both the seat
and the O-rings are loose enough to remove then take out the shaft sleeve O-ring.
When no additional disassembly is needed, refer to Section IV. Part H. INSTALLING
THE SEAL.
F. REMOVING & DISASSEMBLING THE SHAFT & BEARING
The bearing housing should not need to be taken apart if the pump has been
correctly operated and maintained. If there is evidence of damage or wear, then
disassemble the shaft and bearings.
DISASSEMBLY OF THE SHAFT AND BEARING IS NOT RECOMMENDED IN THE FIELD.
PERFORM THESE OPERATIONS ONLY IN A PROPERLY EQUIPPED SHOP BY
QUALIFIED TECHNICIANS.
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.
