Frequently Asked Questions
Q: What components are included in the Clark CL 1808155 hydraulic seal kit?
A: The CL 1808155 seal kit includes all critical U-cups, O-rings, and seal washers marked with A on Clark CJ55 technical diagrams. This complete kit provides all elastomer sealing elements required for hydraulic integrity restoration.
Q: What are the material and durability specifications for the CL 1808155?
A: The CL 1808155 features Viton and polyurethane elastomer construction with Shore A 75-85 hardness for polyurethane elements. These materials withstand abrasive hydraulic service and maintain sealed pressure integrity at 3,000 PSI maximum operating pressure.
Q: Which hydraulic cylinder and piston sizes does the CL 1808155 cover?
A: The CL 1808155 seal kit is compatible with hydraulic cylinders and lift pistons ranging from 1.00 inch to 2.50 inches in diameter. This range covers standard piston bore sizes in Clark CJ55 manual pallet jack hydraulic assemblies.
Q: How does the CL 1808155 support the CJ55 load capacity rating?
A: By restoring seal integrity across the hydraulic circuit, the CL 1808155 kit ensures the Clark CJ55 maintains its OEM rated load capacity of 5,500 lbs and hydraulic reliability. Worn or failed seals compromise load-holding ability and safety.
Q: What is the expected service lifespan of the CL 1808155 seals?
A: Viton and polyurethane seals typically deliver 2-5 years of normal service in manual pallet jack applications depending on usage frequency, operating temperature, and contamination. Regular inspection of hydraulic fluid condition extends seal lifespan.
