Frequently Asked Questions
Q: What Rol-Lift models does the 401626 seal kit fit?
A: The 401626 is compatible with Rol-Lift T Series and E Series manual pallet jacks equipped with 1-5/8 inch lift rams. This kit is designed as a direct replacement for OEM hydraulic pump seal assemblies on these model lines. Verify your equipment series designation and ram bore diameter before ordering.
Q: What seal materials does the 401626 contain?
A: The 401626 includes nitrile rubber (NBR) main seals and O-rings with 70 Shore A hardness rating for reliable hydraulic fluid containment. Thermoplastic polyurethane (TPU) seals and polyoxymethylene (POM) backup washers provide dynamic and static sealing surfaces rated for 3000 PSI service.
Q: What does T5BOK reference mean for the 401626?
A: T5BOK is the original equipment seal kit reference number for Rol-Lift hydraulic pump repairs. The 401626 is manufactured to meet or exceed T5BOK specifications and fitment tolerances, ensuring OEM-level performance and reliability as a direct replacement.
Q: What pressure can the 401626 seals withstand?
A: The 401626 is rated for continuous operation at pressures up to 3000 PSI. All seal components meet AS568B and ISO dimensional standards to prevent internal bypass and maintain system pressure integrity during lifting and load-holding cycles.
Q: How do I identify if the 401626 is the right replacement for my pallet jack?
A: Check your pallet jack model plate for Rol-Lift T Series or E Series designation and measure the lift ram bore diameter (should be 1-5/8 inches). Cross-reference the OEM part number 401626 with your pump assembly documentation. Contact our parts team with your model number and serial range to confirm compatibility.
