Frequently Asked Questions
Q: Which Rol-Lift models and capacities does the RL T5BOK-SLIM fit?
A: The RL T5BOK-SLIM is designed for Rol-Lift manual pallet jacks with 1-5/8 inch lift ram bore. It is compatible with 4500 lb, 5000 lb, 5500 lb, and 6500 lb capacity units across the Rol-Lift product line.
Q: What are the part number cross-references and superseded parts?
A: The RL T5BOK-SLIM is equivalent to RL 7-99001 and supersedes prior Rol-Lift hydraulic ram seal kits for 1-5/8 inch lift rams. It replaces the earlier RL T5BOK designation in current inventory.
Q: What seal components and materials does this kit contain?
A: This kit includes seals for the hydraulic cylinder, rod, and piston manufactured from NBR and polyurethane materials. These elastomers provide reliable performance in high-pressure manual pallet jack hydraulic systems up to 3000 PSI.
Q: Is the RL T5BOK-SLIM different from other Rol-Lift seal kits?
A: The SLIM designation indicates a compact seal arrangement optimized for the 1-5/8 inch bore cylinder design. It provides the same functional hydraulic performance as standard kits while accommodating Rol-Lift Series geometry specifications.
Q: What maintenance indicators suggest needing this seal kit?
A: Replace seals when the jack exhibits slow or incomplete lift cycles, takes multiple pump strokes to reach full height, or shows visible hydraulic fluid around the ram rod. Preventive replacement typically occurs between 2000 and 4000 operating hours.
