SPLIT RING
Frequently Asked Questions
Q: What is the purpose of the 00591-43295-81 split ring in manual pallet jack hydraulics?
A: The 00591-43295-81 is a retaining ring that holds pump pistons and hydraulic valve cartridges in fixed positions within the assembly. The split design allows for easy insertion and removal without disassembly of adjacent components.
Q: Which pallet jack models use the 00591-43295-81 split ring?
A: This split ring fits Toyota, Crown, Raymond, and similar manual pallet jack pump assemblies that use metric retaining ring specifications. Confirm your equipment model and year to verify the correct ring specification for your application.
Q: What material and dimensions specify the 00591-43295-81?
A: The split ring is manufactured from spring steel with a hardness specification that maintains consistent tension around the hydraulic component bore. The ring provides elastic force to prevent axial movement while accommodating standard metric bore tolerances.
Q: What are signs that the 00591-43295-81 split ring needs replacement?
A: Replace the ring if you observe hydraulic fluid leakage from the piston rod area, abnormal piston drift, or visible cracks in the ring material. A weakened ring will lose tension and allow components to shift, compromising pump function.
Q: Is the 00591-43295-81 a consumable or durable part?
A: The split ring is a semi-durable component. Under normal operation, it can last the life of the equipment if not subjected to shock loads or overload cycles. However, repeated pressure spikes or impact can reduce spring tension, requiring replacement every 3000 to 5000 operating hours in heavy-use applications.
