Frequently Asked Questions
Q: What components are included in the GW 510 hydraulic seal kit?
A: The GW 510 kit includes piston seals, rod seals, and wiper seals manufactured from nitrile rubber (NBR). These seals are designed for both the hydraulic pump and cylinder assemblies in manual pallet jack systems compatible with GP 510 and GW 510 series hydraulic units.
Q: Is the GW 510 equivalent to the GP 510 seal kit?
A: Yes. The GW 510 is equivalent to GP 510 and GP510. Both part numbers provide the same seal kit composition and are OEM-compatible for manual pallet jack hydraulic systems. Verify your pallet jack model number to confirm which part number applies to your unit.
Q: What are the symptoms of failing hydraulic seals in a manual pallet jack?
A: Common symptoms include slow or no lift response, external hydraulic fluid leaks near the pump or cylinder, loss of lift height over multiple cycles, hissing sounds during operation, or oil residue on the mast or floor. If you observe any of these, inspect seals immediately to prevent hydraulic fluid loss and equipment failure.
Q: Can I reuse hydraulic fluid when replacing the GW 510 seal kit?
A: No. Change the hydraulic fluid when you replace seals. Old fluid may contain seal debris, water, and contaminants that damage new seals and reduce system performance. Drain the reservoir completely, flush the lines if possible, and fill with fresh ISO 32 or 46 mineral oil-based hydraulic fluid.
Q: What is the expected service life of the GW 510 seals?
A: Seal life depends on duty cycle, fluid condition, and operating temperature. In normal warehouse use (typically 50-100 lift cycles per day), expect 2 to 4 years of service. Heavy-duty applications with continuous lifting may require seal replacement annually. Inspect seals during routine maintenance and replace at first signs of degradation.
