Frequently Asked Questions
Q: What makes and models is the 00591-43203-81 compatible with?
A: The 00591-43203-81 is compatible with manual pallet jacks from Toyota and other similar manufacturers. Confirm your pump design matches a positive displacement hand pump before ordering, as piston size and stroke vary by pump model.
Q: What material is the 00591-43203-81 made from?
A: The 00591-43203-81 is machined from hardened steel and typically fitted with a polyurethane or elastomer seal ring. The seal ensures hydraulic fluid remains pressurized and prevents internal leakage.
Q: When should the 00591-43203-81 be replaced?
A: Replace the 00591-43203-81 if the jack requires excessive handle pumps to lift a load, fails to hold pressure, leaks hydraulic fluid from the pump housing, or makes grinding noises during pumping. Worn pistons cannot create adequate pressure and result in slow or no lift.
Q: How often should the 00591-43203-81 be inspected?
A: Inspect the 00591-43203-81 annually or when you notice a reduction in lift speed or power. In high-use environments or when operating in wet or dusty conditions, inspect every 6 months.
Q: Can the 00591-43203-81 be cleaned and reused?
A: If the 00591-43203-81 is scored, pitted, or the seal ring is damaged, it must be replaced. A worn piston cannot create proper sealing pressure and leads to pump failure.
