7003070

Frequently Asked Questions

Q: What components are included in the 7003070 seal kit?
A: The 7003070 seal kit includes high-performance hydraulic seals, O-rings, dust seals, and back-up rings. These components work together to prevent hydraulic fluid leakage in the pump and cylinder systems of manual pallet jacks.

Q: Which manual pallet jack models does the 7003070 seal kit fit?
A: The 7003070 seal kit fits manual pallet jacks from Crown, Toyota, Raymond, and Yale equipment. Verify your equipment model and serial number match the pump housing specifications before ordering to ensure compatibility.

Q: What materials are used in the 7003070 seal kit, and why?
A: The seals use high-performance elastomers and polyurethane compounds designed to withstand hydraulic pressures up to 2500 PSI, temperature ranges from minus 20 degrees F to 160 degrees F, and continuous fluid contact. Back-up rings prevent seal extrusion under load.

Q: How long does the 7003070 seal kit last before replacement is needed?
A: Seal kit lifespan depends on equipment usage, hydraulic fluid condition, and maintenance frequency. Standard duty cycles yield 2 to 3 years of service. Heavy use or contaminated hydraulic fluid reduces lifespan. Replace immediately if you observe slow descent, difficulty raising the load, or fluid dripping from the pump.

Q: What causes the 7003070 seal kit to fail prematurely?
A: Premature failure results from contaminated hydraulic fluid, extreme temperatures beyond the rated range, improper hydraulic pressure exceeding 2500 PSI, or mechanical damage during use. Regular hydraulic fluid changes and inspection reduce seal degradation.

Q: Is the 7003070 equivalent to other brand seal kits?
A: The 7003070 is a cross-reference replacement for equivalent seal kits across Crown, Toyota, Raymond, and Yale manual pallet jacks. Confirm the pump housing dimensions and seal bore sizes match before substituting. Our parts specialists can verify cross-compatibility with your equipment.
