Frequently Asked Questions
Q: Which Blue Giant manual pallet jack models does seal kit 800064846 fit?
A: This seal kit is compatible with Blue Giant PT-50, MTS 2000, ROI-5, and ROI-55 manual pallet jack models. It also replaces OEM seal kit 810-456 and equivalent seal kits across these model lines. Verify your jack model matches before ordering.
Q: What does SKU 800064846 replace or cross-reference?
A: This kit replaces OEM part number 810-456 and is equivalent to seal kits for ROI-5, ROI-55, and MTS 2000 models. If your service records show original seal kit 810-456 or equivalent part numbers, the 800064846 is a direct replacement with OEM-grade materials.
Q: What is the pressure rating and material specification for this seal kit?
A: The 800064846 is rated for 3000 PSI maximum working pressure and constructed from SAE J200-grade nitrile rubber (NBR) seals with zinc-plated retainer hardware. These materials provide durability and corrosion resistance in high-pressure hydraulic systems supporting jacks rated up to 5000 pounds at 24 inch load center.
Q: What are the bore tolerance specifications?
A: The seal kit is designed for precise fitment with bore tolerances of plus or minus 0.005 inch. This tight tolerance ensures proper seal engagement and prevents internal leakage in the hydraulic cylinder. Measure your cylinder bore before ordering to confirm compatibility.
Q: What load capacity does equipment using the 800064846 seal kit support?
A: Blue Giant pallet jacks equipped with this seal kit are rated up to 5000 pounds at a 24 inch load center. Actual capacity depends on cylinder bore diameter and hydraulic system configuration. The 3000 PSI pressure rating supports these standard warehouse pallet jack capacities.
Q: What is the expected lifespan of this seal kit?
A: In standard warehouse duty, this seal kit typically lasts 4 to 6 years. Lifespan depends on hydraulic fluid condition, duty cycle intensity, and system pressure cycling. Regular hydraulic fluid maintenance and contamination control extend seal life. Replace immediately if hydraulic leakage develops or pressure capacity drops.
