Frequently Asked Questions
Q: What is the purpose of the VJ 55F150 wiper in the hydraulic system?
A: The VJ 55F150 is a high-wear synthetic exclusion wiper designed for piston rod protection within Valu-Jack 5500-2 and 5500-12 manual pallet jack hydraulic units. It prevents external contamination from entering the cylinder bore during rod extension and retraction.
Q: Which seal kits include the VJ 55F150?
A: The VJ 55F150 wiper is referenced in Seal Kit 55FK100, which contains this wiper component plus additional hydraulic seals for complete seal kit replacement. Do not mix individual components from different kit sources unless verified for cross-compatibility.
Q: What hydraulic oils is the VJ 55F150 compatible with?
A: The VJ 55F150 is formulated for use with ISO 32 and ISO 46 hydraulic oils. Confirm your equipment specification before using alternative oil viscosities, as synthetic wiper materials can swell or degrade in non-compatible fluids.
Q: What material is the VJ 55F150 constructed from?
A: The VJ 55F150 is manufactured from high-wear synthetic polymer formulated specifically for repetitive rod contact. This material resists abrasion and maintains sealing integrity across extended operational cycles.
Q: How do I know if the VJ 55F150 needs replacement?
A: Replace the VJ 55F150 if you observe hydraulic fluid leaking from the rod end of the cylinder, visible wiper degradation during inspection, or loss of load holding when extended. Worn wipers allow contamination ingress and reduce seal kit lifespan.
Q: What is the OEM part number cross-reference?
A: Manufacturer part number is VJ 55F150. OEM reference part number is 55F150. Both designations identify the same component. Always verify compatibility with your specific pallet jack serial number before ordering.
