Gusher Pumps Pump CL4×5

Ensure the following conditions are met before lubrication

Remove relief from back of ball bearing housing

Fill with grease until fresh grease flows from opening

Is an automatic lubrication system being used?

If yes, ensure reliefs are placed in the tapped hole (1/8" N.P.T.)

MAINTENANCE — Lubrication / START UP

Check ball bearing temperature using a pyrometer

Is the ball bearing temperature below 225°F?

Note if bearings seem to run tight and hot upon initial startup

Confirm if the pump operates normally after approximately 150 hours of service

INSTALLATION — Coupling Alignment (Chair Mounted Model ONLY)

Check Coupling Alignment before and after system start-up

Place a straight-edge across the two coupling flanges and measure the maximum offset at various points around the periphery of the coupling.

Enter the maximum offset measured (in inches)

Does the maximum offset exceed 0.010 inches?

Realign the coupling if the maximum offset exceeds 0.010 inches.

Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling using a micrometer or caliper.

Disconnect coupling (#32) and remove sleeve (#32a)

Loosen three locking screws (#57)

Loosen three adjusting screws (#55)

Lightly tap shaft (#1) until impeller bottoms on the intake flange

Tighten three adjusting screws by hand until they touch ball bearing housing

Tighten three adjusting screws just up to the point where the shaft turns freely; then tighten each screw an additional ¼ turn

Tighten locking screws (#57) and jamb nuts (#56)

Remove four motor retaining bolts

Break welds loose that hold discharge pipe cover plate to mounting plate

Remove bolts & nuts that hold discharge pipe to impeller housing
