Frequently Asked Questions
Q: What does the compression spring component do in the Model A hydraulic unit?
A: The EA A155 compression spring controls the hydraulic pump mechanism. It maintains pressure regulation in the pump control system and ensures proper valve operation when raising and lowering the pallet jack mast.
Q: What are the specifications for the EA A155 compression spring?
A: The EA A155 is engineered specifically for assembly position A155 in the Model A hydraulic pump assembly schematic. Verify the spring rate, free length, and coil diameter against your equipment documentation to ensure correct replacement.
Q: Are there alternate part numbers for the EA A155 compression spring?
A: Yes. Alternate part numbers for the EA A155 include EAA155 and EGA155. These are cross-references for the same component. Always verify compatibility with your specific pump assembly before substituting.
Q: What are the signs that the EA A155 compression spring needs replacement?
A: Replace the compression spring if the pallet jack loses hydraulic pressure, if the mast descends on its own, if the pump control lever becomes difficult to operate, or if the spring loses its tension and does not return to position.
Q: How long does the EA A155 compression spring typically last?
A: Compression spring lifespan depends on operational frequency and maintenance. With regular maintenance and proper hydraulic fluid levels, the EA A155 spring typically lasts 3 to 5 years in normal warehouse service.
