Frequently Asked Questions
Q: What components are included in the JT PT2748A-101 hydraulic seal kit?
A: The JT PT2748A-101 hydraulic seal kit includes dust seals, O-rings in 29.8 mm and 38 mm inside diameter sizes, polyurethane U-packing, and steel balls. This is a complete seal kit for Jet manual pallet jack hydraulic assemblies. The kit provides all sealing and bearing components in a single package.
Q: Which Jet pallet jack models fit the PT2748A-101 seal kit?
A: The JT PT2748A-101 is a direct-fit replacement for Jet manual pallet jack models A, L, and J. It is compatible with Jet PT2748 series hydraulic units and hydraulic assemblies across all three models. Verify your equipment model before ordering.
Q: What cross-reference or equivalent part numbers exist for PT2748A-101?
A: The JT PT2748A-101 has the following documented cross-references: JTPT2748A-101, PT2748A-101, Jet PT2748A-101, JTPT2748A101, PT2748A101, Jet PT2748A101, and 2748A101. All designations reference the same OEM seal kit. Order using any of these part numbers for compatibility with Jet model A, L, and J pallet jacks.
Q: What material is the U-packing made from in this seal kit?
A: The U-packing in the JT PT2748A-101 kit is manufactured from polyurethane. Polyurethane provides superior wear resistance, flexibility, and chemical compatibility compared to rubber in hydraulic service. It maintains sealing integrity across typical warehouse operating temperatures.
Q: How long does a hydraulic seal kit typically last before leakage occurs?
A: In typical warehouse duty, hydraulic seal kits provide 3-5 years of leak-free service depending on load cycles, operating temperature, and maintenance. Replace the kit if you observe hydraulic fluid leakage, loss of lift pressure, or drift when the jack is under load. These are signs of seal degradation.
Q: What maintenance extends the life of the PT2748A-101 seal kit?
A: Keep the hydraulic reservoir filled with the correct fluid type as specified by Jet. Maintain proper fluid level, inspect for leakage quarterly, and replace the kit if seals begin to weep. Clean hydraulic fluid is critical; contamination accelerates seal wear. Follow Jet maintenance schedules to maximize kit lifespan.
