Follow the daily, hourly or calendar intervals, whichever occurs first.
* If other than CAT Pump Model 6107 oil is used, change cycle should be every 300 hours.
** Each system’s maintenance cycle will be exclusive. If system performance decreases, check immediately. If no wear at 1500 hours,
check again at 2000 hours and each 500 hours until wear is observed. Valves typically require changing every other seal change.
Duty cycle, temperature, quality of pumped liquid and inlet feed conditions all affect the life of pump wear parts and service cycle.
Remember to service the unloader at each seal servicing and check all system accessories and connections before resuming operation.
Contact your local service center if questions arise.
