Product Description
13/16 compression spring
Frequently Asked Questions
Q: What does a 13/16 compression spring do in a forklift?
A: This compression spring provides load return force on lift mechanism components, load backrest assemblies, or hydraulic valve systems. The 13/16 inch diameter is a standard size for medium-duty electric and internal combustion forklifts.
Q: Which forklift brands and models use this 13/16 compression spring?
A: This spring fits Toyota, Raymond, Crown, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT forklifts. Cross-reference your equipment serial number and hydraulic schematic to confirm the exact compression rate and free length match.
Q: What is the compression rating and expected lifespan?
A: Verify the compression rate (pounds per inch) and free length from your forklift service manual, as these vary by application. Under normal duty, expect 2 to 5 years of service. Springs in high-cycle operations or heavy-duty applications fail faster.
Q: What causes compression springs to fail?
A: Springs lose tension and fail due to fatigue cycles, corrosion from moisture, overloading beyond rated capacity, and exposure to extreme temperature swings. A failed spring causes spongy feel during lift, slow descent, or inability to hold load in neutral.
Q: Can a single failed spring be replaced or must springs be replaced in pairs?
A: If one spring has failed, replace all springs in that assembly to maintain balanced force distribution. Installing a new spring alongside a weakened old spring causes uneven lift and accelerates failure of the remaining component.
