Frequently Asked Questions
Q: What seals are included in the BJ 10278 hydraulic seal kit?
A: The BJ 10278 contains Buna-N and polyurethane seals engineered for hydraulic cylinder rebuilds. These materials are selected for compatibility with standard hydraulic fluid and durability under pressure cycling. The seal kit is designed for direct replacement use in Big Joe and Lift-Rite manual pallet jacks.
Q: Which pallet jack models is the BJ 10278 compatible with?
A: The BJ 10278 is compatible with Big Joe and Lift-Rite manual pallet jack model L-50. Alternate model designations are L50 and L 50. The kit is designed specifically for the hydraulic cylinders on these models. Verify your equipment model before ordering.
Q: What is the maximum system pressure rating for the BJ 10278?
A: The BJ 10278 seal kit is rated for system pressure of 3000 PSI nominal. The seals are designed for bores up to 2.5 inches. Verify your hydraulic cylinder bore size and system pressure specifications match this kit before ordering to ensure proper performance and seal longevity.
Q: What are the cross-reference part numbers for the BJ 10278?
A: Cross-reference equivalents include BJ10278-SUPER, LF 10278-SUPER, and 10278 LIFT RITE SEAL KIT. These part numbers reference the same direct replacement hydraulic seal kit for Big Joe and Lift-Rite L-50 equipment. Use the exact part number when ordering to confirm receipt of the correct seal kit.
Q: What factors affect the lifespan of seals in a hydraulic cylinder?
A: Seal lifespan depends on hydraulic fluid condition, system pressure cycles, temperature fluctuations, and contamination levels. Regular hydraulic fluid changes extend seal life by preventing degradation. Buna-N and polyurethane seals degrade over time; periodic rebuilds with fresh seal kits maintain hydraulic performance and prevent fluid leakage.
Q: Does the BJ 10278 kit provide all seals needed for a complete hydraulic cylinder rebuild?
A: The BJ 10278 seal kit contains the seals necessary for hydraulic unit rebuilds on Big Joe and Lift-Rite L-50 models. The kit includes piston and rod seals for comprehensive rebuild coverage. Verify the kit contents match your specific cylinder configuration before use.
