Frequently Asked Questions
Q: Which pallet jack models use the 800075564 piston and cylinder assembly?
A: The 800075564 piston and cylinder assembly is OEM compatible with Toyota, Raymond, and Hyster manual pallet jacks rated 3000 to 5000 pounds. Verify dimensions and port sizes match your pump base before ordering.
Q: What are the specifications of the 800075564 piston and cylinder?
A: The cylinder bore diameter is approximately 2.0 inches with a 10 inch stroke length. The piston rod diameter is 1.25 inches. Maximum working pressure is 3500 PSI. The assembly uses 3/8 inch NPT inlet and outlet ports.
Q: What material is the 800075564 cylinder constructed from?
A: The cylinder tube is seamless steel honed to precision tolerances. The piston is aluminum or ductile iron with precision rings. Hard chrome plating on the rod provides corrosion resistance and extends seal life.
Q: What causes piston and cylinder failure in the 800075564?
A: Internal corrosion from contaminated hydraulic fluid, rod scratch damage from foreign particles, seal degradation, and internal leakage reduce performance. Overloading the jack beyond rated capacity causes accelerated wear and piston stiction.
Q: How long does the 800075564 piston and cylinder assembly last?
A: Under normal warehouse conditions with clean hydraulic fluid, the assembly lasts 5 to 10 years or 500000 to 1000000 lift cycles. High-cycle cold storage use reduces lifespan to 2 to 3 years. Fluid condition is the primary factor affecting longevity.
Q: What maintenance prevents premature 800075564 failure?
A: Change hydraulic fluid annually or every 2000 operating hours. Use ISO Grade 46 hydraulic fluid meeting NFPA D2786 or equivalent. Keep the rod area clean and free of dust or debris. Store the jack in a dry environment to prevent corrosion.
