Troubleshooting 
Water/Moisture in
Pump Gearbox. Leak coming from
above the pump. • Check all piping connections and tank overflow for possible spill-
age falling directly onto the pump gearbox.
• Repair accordingly.
Operating or a driving
condition that sub-
merges the gearbox in
water. • Visually inspect the unit for external signs of water leakage.
• Was the unit submerged in water? Does your unit include an air
vent / breather where water can enter if submerged? If so, change
oil. See Section 4 Preventive Maintenance, heading “Replace
Gearbox Oil” on page 80.
Normal condensation. • Depending on area / region where unit is operated, normal con-
densation can develop over time.
• Periodic inspection and possibly more frequent oil changes are
needed.
Leaking oil seal or
mechanical seal. • Inspect the oil seals and replace as needed. If the oil seal checks
OK, the packing seal or mechanical seal may be leaking.
• There must be NO leaks at the mechanical seal. See Section
“Mechanical Seal Replacement” on page 133.
• Packing seals are designed to leak. For requirements, see “Pack-
ing Gland Adjustment” on page 77.
• Hydrostatic test the system to determine leakage.
Rotation Symp-
toms.
(Reduced pres-
sure 60–100 PSI
[410–690 kPa]
and reduced flow.)
Wrong impeller
installed. • Verify the new impeller vanes are oriented the same as the old
impeller before installing, see Figure 2-13: “Pump/Engine Rota-
tion” on page 35.
• Refer to relief / sensing valve manual and follow maintenance
instructions for disassembly, cleaning and lubrication.
Impellers installed
backwards (two-stage
pump). • Verify the impellers are in the correct order - p/n: 016-0280-00-0 is
installed closest to the gearbox in an “Engine Rotation” applica-
tion and CLosest to the front in a “Opposite Engine Rotation”
application.
Wrong application
attempted. • The pump was installed on an application for which it was not
intended, i.e., front mount vs. rear mount.
NOTICE!
IT IS POSSIBLE TO REASSEMBLE THE PUMP INCORRECTLY OR WITH THE
WRONG PARTS. ALWAYS COMPARE THE REPLACEMENT PARTS WITH
THE ORIGINAL HARDWARE. CONTACT CUSTOMER SERVICE AT HALE PRODUCTS TO
ANSWER QUESTIONS OR CONCERNS.
