Frequently Asked Questions
Q: What Rol-Lift models does the 401866 seal kit fit?
A: The 401866 is compatible with Rol-Lift T Series and E Series manual pallet jacks equipped with a 1-5/8 inch lift ram. Confirm your jacks have this ram diameter before ordering.
Q: What are the cross-reference part numbers for the 401866?
A: The 401866 is equivalent to RL T5BOK, RL T5BOK-F-SUPER, RL T5BOK-H-SUPER, and T5BOK. It supersedes the earlier RL T5BOK designation.
Q: What components are included in the 401866 kit?
A: This kit includes NBR seals and backup rings designed specifically for restoring hydraulic cylinder sealing integrity. The combination of seals and backup rings prevents fluid bypass and maintains pressure in the lift system.
Q: What is the purpose of backup rings in this seal kit?
A: Backup rings support the primary seal under high pressure, preventing extrusion and extending seal life. In pallet jack cylinders operating at 3000 PSI, backup rings are critical for maintaining a tight seal over thousands of cycles.
Q: How do I confirm the 401866 is correct for my Rol-Lift equipment?
A: Verify that your jack is a Rol-Lift T or E series model and measure the lift ram diameter to confirm it is 1-5/8 inches. Cross-reference your equipment part number against RL T5BOK or T5BOK. If your model matches these criteria, the 401866 is correct.
