Hydraulic Oil and Filters:
Oil Quality: The cylinder's health is directly tied to the health of the hydraulic system. Contaminated oil is the number one cause of internal seal and component wear.
Filter Changes: Strictly adhere to Caterpillar's recommended service intervals for changing the main hydraulic return filter and case drain filters. Using genuine Cat filters is highly advised for their superior filtration efficiency.
Oil Analysis: Implement a regular S·O·S (Scheduled Oil Sampling) program. This fluid analysis can detect excessive wear metals, water contamination, and chemical breakdown of the oil long before it causes a failure.
