Frequently Asked Questions
Q: What hydraulic ram sizes does this kit fit?
A: This seal kit is engineered for 1-3/8 inch diameter hydraulic lift rams. It fits Rol-Lift manual pallet jacks in the 3000 lb and some 4500 lb capacity models with matching 1-3/8 inch bore lift arms.
Q: What seal materials are included?
A: This kit uses NBR (nitrile) hydraulic seals for both piston and rod assemblies. NBR delivers reliable fluid retention and pressure sealing in standard manual pallet jack hydraulic systems, with typical operational lifespan of 3-5 years under normal material handling duty cycles.
Q: What hydraulic oils are compatible with this kit?
A: This kit is designed for ISO VG 32 and ISO VG 46 hydraulic oils. These are standard mineral-based hydraulic fluids commonly used in manual pallet jack systems. Always confirm your jack's maintenance manual before refilling the hydraulic reservoir.
Q: Are there cross-reference part numbers for this kit?
A: Yes. This part is also referenced as T5AOK, RLT5AOK, and T5AOK-TH. If you encounter any of these numbers in old documentation or invoices, they refer to the same seal kit.
Q: How do I determine if my Rol-Lift pallet jack needs this seal kit?
A: Check the lift ram bore diameter on your jack. Measure the diameter of the vertical hydraulic cylinder rod that extends when you pump the handle. If it measures approximately 1-3/8 inches, this is the correct kit. Rol-Lift 3000 lb models and some 4500 lb models use this size; higher-capacity models typically use 1-5/8 inch rams requiring different seal kits.
Q: How should this seal kit be stored?
A: Store seals in a cool, dry location away from direct sunlight, extreme heat, and moisture. Keep original packaging intact until ready for use to prevent dust and contamination of seal surfaces.
