74 Pump Ends

Insufficient Pump
Capacity -
continued. Air leaks. • See heading “Air leaks.” under condition “ Pump Loses Prime or
Will Not Prime” on page 73.
Partial collapse of the
lining in a suction hose. • Damage to the outer lining may allow air between the outer and
inner linings causing a partial collapse.
• Replace hose and retest.
Engine governor set
incorrectly. • If the engine governor is set too LOW (pressure), when on auto-
matic, engine speed decelerates before the desired pressure is
achieved.
• Reset governor per manufacturer’s procedures.
Truck transmission in
wrong gear or clutch is
slipping. • Recheck the pumping procedures for the recommended transmis-
sion or gear range - review Section “Pumping Operations,” begin-
ning on page 47.
• Use a mechanical speed counter on the pump panel to check
speed against possible clutch or transmission slippage or inaccu-
rate tachometer.
• Check truck manual for proper speed counter ratio.
Insufficient Pres-
sure. Insufficient engine
power. • See previous heading “Insufficient Pump Capacity.” on page 73.
Remote Control
Difficult to Oper-
ate. Lack of lubrication. • Lubricate the remote control linkages and collar with oil. For lubri-
cant recommendations, see “Appendix C1: Lube and Sealant
Specifications” on page 139.
Engine Speeds
Too HIGH for
Required Capac-
ity or Pressure.

Truck transmission in
wrong gear or range. • Recheck the pumping procedures for the recommended transmis-
sion or gear range - review Section 3 “Basic Operation,” beginning
on page 45.
• Check truck manual for proper speed counter ratio.
Lift too high, suction
hose too small. • Higher than normal lift (10 ft. / 3.1m) causes higher engine speeds,
high vacuum and rough operation.
• Use larger suction hose.
• Move the pump closer to the water source.
Faulty suction hose. • Inner lining of suction hose may collapse when drafting and is usu-
ally undetectable.
• Try a different suction hose on the same pump.
• Test for comparison against original hose.
Blockage at suction
hose entry. • Clean suction hose strainer of obstruction. Also see Section 4 Pre-
ventive Maintenance, heading “Intake Strainers” on page 60.
• Follow recommended practices for laying suction hose.
• Keep off the bottom of the fluid supply by at least 2’ (0.6 meters)
below the surface of the fluid.
