Frequently Asked Questions
Q: What does the VJ 55F137 spring component do in a Valu-Jack pallet jack?
A: The VJ 55F137 is a spring component for Valu-Jack 5500-2 hydraulic units. Springs in manual pallet jack systems provide return force for pump valves and levers, ensuring the jack returns to neutral position after each lift cycle.
Q: Which Valu-Jack models use the VJ 55F137 spring?
A: The VJ 55F137 fits Valu-Jack 5500-2 Hydraulic Unit, 55002 Hydraulic Unit, and 5500-2 Hydraulic Unit variants. These designations refer to the same equipment generation. Verify your hydraulic unit model before ordering to ensure compatibility.
Q: What symptoms indicate the VJ 55F137 spring needs replacement?
A: Replace the VJ 55F137 if the pump handle does not return to neutral position automatically, if the lift action feels sluggish, or if the lever stays partially engaged after releasing pressure. A weakened or broken spring will cause these symptoms and reduce control over the lift function.
Q: How long does the VJ 55F137 spring typically last?
A: Spring lifespan depends on frequency of use and operating conditions. With regular warehouse use, a spring typically lasts 2-5 years before losing tension. Springs in high-volume distribution centers may require replacement more frequently. Environmental exposure to extreme cold can accelerate spring degradation.
Q: Is the VJ 55F137 an OEM spring?
A: Yes, VJ 55F137 is an OEM-specification spring for Valu-Jack brand equipment. It is manufactured to match original equipment performance and pressure characteristics. Using non-OEM springs may result in improper lift pressure or valve response.
