CR 805108

Frequently Asked Questions

Q: What Crown pallet jacks require CR 805108 pinion?
A: CR 805108 is a pinion gear for Crown model ST 3000 electric pallet jacks. The alternate model designation is ST3000. Verify your equipment serial range and model match ST 3000 before ordering this component.

Q: How does CR 805108 differ from CR 805105?
A: Both CR 805108 and CR 805105 are pinion gears for Crown ST 3000 models. The difference may be in design revision, tooth geometry, pitch, or load rating. Do not assume interchangeability. Consult your Crown parts manual or equipment serial documentation to confirm which pinion your specific unit requires.

Q: What are the symptoms of CR 805108 pinion wear?
A: Worn or damaged pinions produce grinding, whining, or chattering noise during lift cycles. Metal shavings appear in hydraulic fluid. Lift action becomes jerky or hesitant, especially under full load. In severe cases, complete drive loss or inability to lower the mast occurs.

Q: What maintenance extends CR 805108 pinion life?
A: Keep hydraulic fluid clean and at the correct viscosity per Crown ST 3000 specifications. Change fluid at recommended intervals, typically 500 to 1000 operating hours. Use only Crown-approved fluid grades to ensure proper lubrication and reduce tooth wear and heat buildup.

Q: How long does CR 805108 typically last in service?
A: Under normal warehouse duty with proper maintenance, CR 805108 pinion gears last 2500 to 4500 operating hours. High-duty cycles, cold storage, or wet floor operations reduce lifespan to 1500 to 2500 hours. Overloading and poor fluid maintenance are the fastest causes of premature failure.
