Frequently Asked Questions
Q: What are the exact dimensions and material specs of the CL 1808105 roll pin?
A: The CL 1808105 is a high-carbon spring steel roll pin with the following specifications: 6.0 mm diameter, 32 mm length, material SAE 1070-1090 spring steel, minimum Rockwell hardness C45. It is an interference-fit component designed for hydraulic linkage applications on Clark CJ55 pallet jacks.
Q: Why is Rockwell C45 hardness significant for the CL 1808105?
A: Rockwell C45 minimum hardness ensures the pin possesses sufficient material strength to resist shear, bending, and wear during repeated hydraulic lever cycles. Higher hardness resists deformation under the press-fit interference condition and maintains dimensional stability throughout the pallet jack operational lifespan.
Q: Is the CL 1808105 compatible with other pallet jack models or brands?
A: No. The CL 1808105 is manufactured to OEM specification for Clark CJ55 manual pallet jacks only. The specific dimensional and material properties are not interchangeable with other brands or models. Verify your equipment matches before ordering.
Q: What role does the interference fit play in the CL 1808105 function?
A: The interference fit creates a permanent, secure retention of the pin within the hydraulic linkage assembly. This eliminates looseness and maintains precise alignment of control lever components. The SAE 1070-1090 material and C45 hardness are specified to withstand the stress of interference fit without deforming.
Q: How does SAE 1070-1090 spring steel compare to other pin materials in durability?
A: SAE 1070-1090 high-carbon spring steel offers superior fatigue resistance and spring-back properties compared to lower-carbon grades. This material resists permanent deformation under cyclic stress, maintains elasticity over extended service life, and provides consistent performance in high-vibration hydraulic environments. The specification ensures durability matching Clark CJ55 operational demands.
Q: What environmental factors affect CL 1808105 performance?
A: The SAE 1070-1090 steel is susceptible to corrosion in wet or salt-spray environments, which can reduce material strength and hardness. Extreme cold may increase brittleness, while sustained heat above 200 degrees Celsius can soften the material and compromise hardness specification. Store and operate the pallet jack in protected conditions to maximize pin lifespan.
