TROUBLESHOOTING AND MAINTENANCE

FUSE REPLACEMENT

1. Place the power switch in the off position.
2. Disconnect the AC power input line cord
from the attached line and receptacle.
3. Remove and check the fuse and replace if
defective
4. Reconnect the AC power input line cord to
the receptacle.

SHAFT SEAL INSPECTION

1. Remove any pump(s) attached to the front
of the drive. Clean any foreign material from
the outside diameter of the drive shaft.
2. Remove the (4) screws (Item B) that hold the front plate assembly (Item A) to the drive, and pull the front plate
assembly off the drive. #8-32 screws may be installed in the pump-mounting holes to provide handles for pulling the
plate assembly off. Retain Item B screws for Step 8. DO NOT substitute other screws.
3. Turn the front plate over so that
the seal side is visible. Wipe the
elastomeric seal lips with a clean
cloth to remove any grease and
foreign material.
4. Inspect the elastomeric seal lips
for tears or cuts or missing
material. If any of the mentioned
conditions exist, replace the seal
assembly using the 07575-01
replacement seal kit.
5. Wipe the exposed part of the
drive shaft with a clean cloth.
Wipe from the drive outward, to
remove all grease and foreign
matter.
6. Inspect the shaft surface in the area touched by the seal. Look for a rough finish, or grooves parallel to the shaft
length. If the shaft end is worn or damaged, as described above, replace the gear and shaft with the 07575-02 kit.
A polished groove, concentric to the outside of the shaft, is not a defect, as long as the groove is no more than
0.002 inches deep.
7. Prior to re-assembly, re-lubricate the shaft and the seal with the food-grade lubricant provided with the unit.
CAUTION: Do not contaminate the lubricant in the container, on the shaft or on the seal with foreign material.
Failure to observe this precaution may result in damage to the seal and premature failure of the seal.
8. Slide the front plate assembly back over the shaft and onto the locating pins, in the orientation desired.
(4 configurations, each 90 degrees of rotation apart, are possible). Reinstall the 4 screws, removed in Step 2
above. CAUTION: No foreign matter should be allowed under the gasket on the back of the front plate or under
the heads of the screws. Failure to observe this precaution may result in leakage during washdown of the drive.
