If other than CAT Pump Model 6107 oil is used, change cycle should be every 300 hours.
** Eachsystem'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.
