Additional Notes
- The Caterpillar AP-800B (serial 1BF00225 and up) differential holds 9 liters, which represents a service fill capacity for routine fluid changes rather than a full overhaul volume.
- Under normal use conditions, the differential fluid change interval is set at 1,000 hours or 12 months, whichever comes first, meaning both a time-based and an hours-based threshold govern when service is due.
- The dual-interval structure of 1,000 hours paired with a 12-month calendar limit reflects standard practice for equipment that may accumulate operating hours at varying rates depending on seasonal or project-based workloads.
