the seal off of the shaft as one unit. Drain the oil in the seal cavity by removing the seal cavity drain plug, located on
the bearing housing’s bottom front boss (refer to Drain Plug Illustration on
). Clean and replace the drain
plug after draining seal cavity of oil. Remove the seal housing from the bearing frame, and place it, face down, on a
flat surface. With a suitable tool, press on the backside of the stationary seat until it is removed from the seal housing.
SHAFT AND BEARING
With the mechanical seal removed, remove the bearing housing drain plug located on the front bottom left of the
bearing frame (refer to Drain Plug Illustration on
), and drain oil. Clean plug and reinstall in housing. Remove
fasteners and slide the bearing cap/SAE bracket and grease seal off the shaft. Press the grease seal from the bearing
cap/SAE bracket. Place a block of wood against the impeller end of the shaft and gently tap the shaft and bearings
out of the housing.
BEARING REMOVAL
Remove the shaft snap ring. This will require the use of snap ring pliers. It will be necessary to use a puller or hydraulic
press to remove the drive end bearings and pump end bearing from the shaft. If the bearings are to be reused, be
certain that puller jaws bear only against the inside races (shaft side) of the bearings.
