Frequently Asked Questions
Q: Which CAT Lift Trucks models use GW 527 seals?
A: GW 527 is equivalent to multiple CAT Lift Trucks part numbers including A000015827, A000011624, A000000856, A000002252, A000000878, A000000871, A000000873, A000000876, A000000885, A000002650, A000000829, A000000830, A000001754, A000000855, A000000827, and A000000886. These cross-references cover various CAT manual and electric lift pump assemblies. Verify your pump assembly part number against this list before ordering.
Q: Is GW 527 compatible with Mitsubishi and Nissan pallet jacks?
A: Yes. GW 527 is engineered to OEM specifications for CAT, Mitsubishi, and Nissan manual pallet jack pump assemblies. GW 527 contains the same seal profiles and material specifications required by all three manufacturers. If your pallet jack is branded Mitsubishi or Nissan, verify that your pump assembly is compatible with GW 527 by checking the pump cross-reference documentation or contacting the manufacturer.
Q: What materials does GW 527 contain?
A: GW 527 is constructed from nitrile rubber (NBR) and PTFE (polytetrafluoroethylene). NBR provides general sealing and durability in oil, while PTFE reduces friction and prevents stiction. This combination is suitable for manual pump assemblies operating at standard pressure ranges. Both materials are compatible with standard mineral hydraulic oils and are resistant to temperature variations typical in industrial lift truck applications.
Q: What is the working pressure rating of GW 527?
A: GW 527 is rated for working pressure up to 3000 PSI, which is the standard maximum for manual pallet jack and lift truck hydraulic pump assemblies. Do not operate GW 527 seals in systems exceeding this rating, as material degradation and seal failure will occur.
Q: Should I order GW 527 as a preventive maintenance seal kit?
A: Yes. GW 527 is an effective preventive maintenance seal kit for CAT, Mitsubishi, and Nissan manual pallet jacks and lift trucks. Even if the pump is functioning normally, replacing seals during scheduled maintenance (typically every 3 to 5 years) prevents unexpected leaks and pressure loss. Preventive replacement is more cost-effective than emergency repairs when a seal fails under load.
