Frequently Asked Questions
Q: What is the ML B147 and which pallet jacks use it?
A: The ML B147 is a hydraulic pump piston for Mighty Lift ML55 series manual pallet jacks with 5500 lb load capacity. It is an OEM replacement component for B-series pump assemblies and is a critical wear element in the hydraulic lifting mechanism.
Q: What are the cross-reference part numbers for the ML B147?
A: The ML B147 cross-references to OEM part number 150-6017 (which it supersedes) and part number 147 (direct interchange). CFA Material Handling 5500 lb capacity units and E-Z-V Lift equipment with compatible pump designs may also accept this piston.
Q: What is the material and hardness specification for the ML B147?
A: The ML B147 is typically manufactured from high-carbon steel with hardened sealing surfaces to withstand repeated compression cycling in the hydraulic pump. The hardness specification ensures the piston maintains its seal against the pump cylinder wall under the 5500 lb load rating.
Q: How long does the ML B147 piston typically last in service?
A: Piston lifespan depends on usage intensity and maintenance. Under normal conditions, an ML B147 in a Mighty Lift ML55 may function for several years. Frequent use in high-cycle operations, contaminated hydraulic fluid, or wear of associated seals and springs will accelerate piston wear and require earlier replacement.
Q: What symptoms indicate the ML B147 piston needs replacement?
A: Difficulty building hydraulic pressure, inability to reach full lift height, hydraulic fluid leaking from the pump, or slow/weak lifting performance on your Mighty Lift ML55 may indicate piston wear or damage. The piston works with seals and springs that must be replaced together for proper function.
