Frequently Asked Questions
Q: What is included in the 00591-43258-81 packing kit?
A: The 00591-43258-81 is a seal and gasket packing kit for electric forklift pump assemblies. The kit contains shaft seals, O-rings, pump port gaskets, and valve body seals. These components prevent hydraulic fluid leakage from pump pressure lines and rotating shafts.
Q: Which forklift pump models use the 00591-43258-81 packing kit?
A: This packing kit fits electric forklift variable displacement pumps from Crown, Toyota, Raymond, Hyster, Jungheinrich, Linde, and Clark. Compatibility applies to 36-volt and 48-volt traction motor drive systems. Verify pump model and displacement rating match before ordering.
Q: What materials are used in the 00591-43258-81 seals and gaskets?
A: The kit contains nitrile rubber seals, PTFE backup rings, and cork fiber gaskets. These materials resist hydraulic mineral oil and maintain seal integrity across pump operating temperatures. Shaft seals are precision-cut to OEM dimensions for a tight fit on pump shafts.
Q: How often should the 00591-43258-81 packing kit be replaced?
A: Replace this kit when you observe hydraulic fluid weeping around the pump shaft or valve body. Preventive replacement is recommended every 6 to 8 years or after 4,000 to 6,000 operating hours. Worn seals cause fluid loss, reduced pump pressure, and potential system damage.
Q: Are there equivalent packing kit part numbers to 00591-43258-81?
A: Cross-reference this kit against OEM pump rebuild kits from forklift manufacturers. Some pumps use proprietary seal cartridges that differ in design. Aftermarket suppliers offer seal kits under different SKUs; verify seal diameter, shaft size, and port gasket dimensions before substituting.
