TUBE ASSEM. 6P8503 - Caterpillar

When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death.
Note: The surface of the seal outside diameter and the counterbore in the equalizer bar should be clean, dry, free from grease, oil, and loosely adhering contaminants. Never clean the surfaces with gasoline, naphtha, or other solvents which leave a film after drying.
Ensure that the sealing surfaces of the seals and of the equalizer bar are smooth and clean.
