401625

Frequently Asked Questions

Q: What is the 401625 seal kit designed to repair?
A: The 401625 is a Rol-Lift manual pallet jack hydraulic seal kit that repairs internal leakage in the hydraulic pump and cylinder assembly. This kit includes all primary seals, backup washers, and O-rings needed for a complete hydraulic system overhaul on manual pallet jacks.

Q: What materials are in the 401625 seal kit?
A: The 401625 contains high-performance elastomeric seals and O-rings manufactured from nitrile rubber (NBR) and thermoplastic polyurethane (TPU) compounds. These materials provide broad compatibility with ISO VG 46 hydraulic oil and offer reliable performance across standard temperature ranges.

Q: What pressure rating does the 401625 seal kit support?
A: The 401625 is engineered for hydraulic systems rated up to 3000 PSI. All seals meet AS568B and ISO fitment tolerances to maintain full pressure containment and prevent internal leakage during normal and peak load operations.

Q: How do I know if the 401625 is the correct kit for my Rol-Lift manual pallet jack?
A: Verify your pallet jack model and inspect the pump and cylinder assembly for the Rol-Lift brand identification. Cross-reference your equipment serial number or model plate with OEM documentation. The 401625 fits standard Rol-Lift manual pallet jack hydraulic systems; confirm pump and cylinder bore sizes match before ordering.

Q: How often should the 401625 seal kit be replaced?
A: Seal kits typically last 5 to 10 years depending on hydraulic fluid condition, operating temperature, and duty cycle. Replace the 401625 when you observe visible hydraulic leakage at pump ports, slow lifting action, or difficulty maintaining load pressure. Preventive maintenance with regular hydraulic fluid inspection extends seal life.
