Dismantling and Installing Pump Drive
Disconnect and lock0out electrical power source. Disconnect wires at electric motor (make a
note regarding where the wires were attached). Remove connecting rod pin in drive hub.
Remove four 3/8 inch bolts holding bearing housing to suction hopper. Entire unit will now lift
clear of suction hopper. There is approximately 1/16 inch clearance all around between the drive
collar and the center hole into the suction hopper and plate. Set-up concrete may block passage
of drive collar through housing.
To install a new unit, reverse the above procedures, paying particular attention to the following:
Pack drive collar with Esso Nebula EP2 or equivalent grease. On the bearing housing is a raised
boss which fits into a counter bore in the suction hopper bolting face. Examine both of these
sections for burrs. Remove with flat mill file. Make sure all foreign matter is removed from all
mating surfaces. Wipe with grease after cleaning. Tighten the four housing bolts up alternately,
so that housing faces contact securely all the way around. Reconnect connecting rod pin and
reconnect wires to the motor according to the notes you took above.
