TroublePossible CauseRemedy
Oil leaking in the area of water pump crankshaftWorn crankshaft seal, bad bearing, grooved shaft, or failure of retainer o-ring.Remove and replace.
Excessive play on crankshaftDefective bearings. Excess shims.Set up crankshaft.
Loud knocking in pumpLoose connecting rod screws.Tighten connecting rod screws per PUMP SPECIFICATIONS
Worn connecting rod.Replace connecting rod per PUMP MAINTENANCE. Replace bearings per PUMP MAINTENANCE. Tighten plunger screw per PUMP SPECIFICATIONS.
Oil leaking at the rear portion of the pumpDamaged or improperly installed oil gauge window gasket or rear cover. Oil gauge loosed.Replace gasket or o-ring.
Rear cover screws loose.Tighten oil gauge.
Pump overfilled with oil, displaced through crankcase breather hole in oil cap/dipstick.Tighten rear screws to torque values in PUMP SPECIFICATIONS.
Drain oil. Refill to recommended oil level as stated in OIL LEVEL in PUMP MAINTENANCE.
Water in crankcaseMay be caused by humid air condensing into water inside. Worn or damaged plunger screw o-ring.Maintain or step up lubrication schedule.
Remove and replace.
Worn bearingExcessive belt tension. Oil contamination.Check oil type and change intervals per PUMP SPECIFICATIONS.
Short bearing lifeExcessive belt tension. Misalignment between pump and motor.Re-align pump and motor.
Oil has not been changed on regular basis.Check oil type and change intervals per PUMP SPECIFICATIONS.
Short seal lifeDamaged plunger bushing. Worn connecting rod. Excess pressure beyond the pump’s maximum rating. High water temperature.Replace plunger bushing.
Replace connecting rod.
Match pressure stated in PUMP SPECIFICATIONS.
Lower water temperature stated in PUMP SPECIFICATIONS.
Dirty or worn check valvesNormal wear. Debris.Remove and replace.
Check for lack of water inlet screens.
Presence of metal particles during oil changeFailure of internal component. New pump.Remove and disassemble to find probable cause.
New pumps have machine fillings and debris and should be drained and refilled per PUMP SPECIFICATIONS.

Defective bearing.Remove and replace bearing. Remove and replace.
Frequent or premature failure of the packingScored, damaged, or worn plunger.Remove and replace plungers.
Overpressure to inlet manifold. Abrasive material in the fluid being pumped.Reduce inlet pressure.
Excessive pressure and/or temperature of fluid being pumped. Over pressure of pumps.Install proper filtration on pump inlet pumping.
Running pump dry.Check pressures and fluid inlet temperature. Be sure they are within specified range.
Reduce pressure.
Do not run pump without water.
Low PressureDirty or worn check valves. Worn packing.Clean/replace check valves.
Belt slipping.Remove and replace packing.
Improperly sized spray tip or nozzle.

Foreign particles in valve assemblies.See temperature in PUMP SPECIFICATIONS.
Scored plungersAbrasive material in fluid being pumped.Install proper filtration on pump inlet plumbing.
Fitted plungersCavitation.Decrease inlet water temperature and/or increase inlet water pressure.
CavitationHigh inlet fluid temperature, low inlet pressure.Lower inlet fluid temperature and raise inlet fluid pressure.
