3.Install and adjust first hex nut for proper bushing clearance of 0.020" [.50mm].

4.Hold adjustment nut from turning and install and tighten the lock nut.

5.Recheck bushing clearance.

IMPORTANT: INADEQUATE CLEARANCE OR LOOSE LOCK NUT WILL CAUSE THE ECCENTRIC TO BIND, RESULTING IN PUMP STALLING AND PREMATURE BUSHING WEAR.

6. Follow steps 1 through 5 in “To Install the Diaphragm” on page 4.

D. ECCENTRIC PIN INSPECTION AND REPLACEMENT

To Inspect:

1.Follow steps 1 and 2 in the rod bushing inspection and replacement section.

2.Inspect the eccentric pin diameter for wear. If worn beyond the service limit replace the eccentric.

New: 0.6248" [15.87mm]

Service Limit: 0.622" [15.80mm]

3.Remove the eccentric by loosening the pinch bolt and jamming a flat- blade screwdriver into the pinch bolt slot.

To Install:

1.Slide the new eccentric onto the output shaft until the output shaft is flush with the end of the eccentric. Make certain the key is in the keyway and flush with the end of the eccentric. (See Fig. 7)

2.Slide eccentric in or out to adjust eccentric to speed (gear) reducer clearance of 0.075" [1.9mm], tighten pinch bolt and check clearance.

3.Follow step 3 (To Inspect) and steps 1 through 6 (To Install) in Rod Bushing Inspection and Replacement section. (See Fig. 7)

Fig. 7

IMPORTANT: IF OUTPUT SHAFT IS NOT FLUSH WITH ECCENTRIC AFTER CLEARANCE, ADJUSTMENT WILL BE NECESSARY. LOOSEN THE OUTPUT SHAFT SET SCREWS AND SLIDE THE OUTPUT SHAFT IN OR OUT ACCORDINGLY.

E. DUCKBILL VALVE INSPECTION AND REPLACEMENT

To Inspect:

1.Flush the pump with fresh water and disinfectant.

2.Close the maintenance valves (if installed) in the inlet and outlet piping.

3.Turn off/disconnect electrical source to the pump motor.

4.Disassemble the inlet/outlet flanges, elbows, and valve housings. (See Fig. 8)

5.Remove the four (4) duckbill valves. Replace all valves if any appear to be: swollen, out of shape, torn, scuffed, slit or show any other sign of wear.

CAUTION: ORDER VALVES MADE OF EPDM (PART NUMBER: 348702) FOR ALL SEWAGE APPLICATIONS.

ORDER VALVES MADE OF NITRILE (PART NUMBER: 342684) FOR OIL-CONTAMINATED WATER APPLICATIONS.

To Install:

1.Insert the two inlet valves pointing toward the pump body. (See Fig. 8)

2.Insert the two (2) outlet valves pointing away from the pump body. (See Fig. 8)
