Frequently Asked Questions
Q: What is the IN 415055 release lever and what does it do on a manual pallet jack?
A: The IN 415055 is the release lever that operates the pump valve to lower the load on an Interthor manual pallet jack. Pulling or squeezing this lever opens the hydraulic valve, allowing fluid to return to the reservoir and the mast to descend in a controlled manner.
Q: Which pallet jack models use the IN 415055 release lever?
A: The IN 415055 release lever is a component for Interthor manual pallet jacks. Fitment depends on your specific model and year. Confirm compatibility with your equipment serial number, as lever geometry and attachment points differ across Interthor product lines.
Q: What material is the IN 415055 release lever made from?
A: The IN 415055 release lever is typically ductile iron or aluminum alloy with a textured grip coating. The material provides durability under repeated cycle stress while maintaining operator comfort. The lever must be rigid to withstand daily operation without flex or fracture.
Q: What symptoms indicate the IN 415055 release lever needs replacement?
A: Replace the IN 415055 if the lever no longer functions smoothly, if it is cracked or bent, if load descent is slow or jerky, or if the lever no longer returns to the neutral position. A failed release lever prevents safe lowering of the load and creates a safety hazard.
Q: Can the IN 415055 release lever be used with different pump designs or manufacturers?
A: No. The IN 415055 is engineered specifically for Interthor pump valve assemblies with matching bore size, valve seat geometry, and actuation linkage. Using this lever with non-Interthor equipment or different pump models will result in poor control or complete failure to lower load.
