Frequently Asked Questions
Q: What is the VJ 55F149 spring designed for?
A: The VJ 55F149 is a precision compression spring engineered specifically for hydraulic actuator retraction in Valu-Jack 5500-2 manual pallet jack units. It supports reliable hydraulic control function and extended operational cycle life.
Q: What material specification does the VJ 55F149 meet?
A: The VJ 55F149 is manufactured from high carbon steel per SAE J995 Grade 5 with a minimum Rockwell C40 hardness rating. This material specification ensures durability under repeated compression cycles in hydraulic applications.
Q: Which Valu-Jack models is the VJ 55F149 compatible with?
A: The VJ 55F149 fits Valu-Jack 5500-2 Hydraulic Unit pallet jacks. Alternate model designations include 55002 Hydraulic Unit and 5500 2 Hydraulic Unit.
Q: Is the VJ 55F149 a direct OEM replacement?
A: Yes. The manufacturer part number and OEM part number are both VJ 55F149, making this a direct replacement component for your equipment.
Q: What is the typical lifespan of this compression spring in field use?
A: Lifespan depends on hydraulic oil condition, operating pressure consistency, and cycle frequency. Springs maintaining SAE J995 Grade 5 hardness rating typically provide extended operational life in properly maintained hydraulic systems. Spring failure typically manifests as loss of retraction force or slower actuator response.
