Frequently Asked Questions
Q: What is the bearing size and part number for EC PLH-P102?
A: The EC PLH-P102 is a thrust bearing assembly, size 51109 (metric designation). This is a standard bearing that transfers vertical load from the pump rod to the frame structure in the pallet jack.
Q: Which Ecoa pallet jack models use the 51109 thrust bearing?
A: The EC PLH-P102 (51109 thrust bearing) is compatible with Ecoa model designation 51109. Verify your equipment model matches this specification. The bearing fits within the pump assembly cavity and requires proper bore dimensions.
Q: What causes thrust bearing failure in a pallet jack?
A: Thrust bearing failure occurs from sustained overload, contaminated hydraulic fluid, inadequate lubrication, or wear from lateral misalignment of the pump rod. Symptoms include grinding noise, rough handle feel during pumping, or inability to achieve full lift.
Q: How do I know if the EC PLH-P102 bearing needs replacement?
A: Signs include grinding or squealing from the pump area, increased vibration during lift cycles, or a notchy feel in the pump handle. If the bearing exhibits play or makes noise under load, replacement is necessary.
Q: What is the load rating for the 51109 thrust bearing?
A: The 51109 is a standard metric thrust bearing rated for moderate radial and axial loads typical of manual pallet jack pump assemblies. For exact load ratings and dimensional specifications, reference the bearing manufacturer datasheet for ISO 51109 standard bearings.
