Gusher Pumps Pump CL4×6

Apply mounting force against the ring being press-fitted

Ensure no pressure or hammer blows are applied to the other ring

Use an arbor press with a face block contacting only the bearing inner ring

Press the shaft through the bearing until seated firmly against the shaft shoulder

Ensure the tubing is clean and slightly greater in diameter than the bearing journal

Ensure the tubing end is square and contacts only the bearing inner ring

Align the shaft with the ram of the arbor press to avoid cocking

Installation — Impeller Adjustment

Verify clearance between impeller and housing or intake flange

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

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)

Verify coupling alignment before and after system start-up

Check Parallel Alignment by placing a straight-edge across the two coupling flanges and measuring the maximum offset at various points around the periphery of the coupling. Realign if offset exceeds .010”.

Check Angular Alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling. Ensure the difference between maximum and minimum does not exceed .010”.

Ensure all screws are tightened before operating the pump.

Notes or observations during the alignment check

Adjustment Procedures if Coupling Alignment is Out

Adjust Lateral Parallel Misalignment by loosening the four motor retaining bolts and adjusting lateral screws until alignment is achieved. Check if misalignment is more than .020”.

Adjust Horizontal Parallel Misalignment by loosening the four motor retaining bolts and adding or subtracting shims as needed. Ensure total shims do not exceed 0.1875”.
