Preventative Transmission Maintenance
A good Preventive Maintenance (PM) program for your Eeaton Fuller transmission can avoid breakdowns, or reduce the cost or repairs. Often, transmission problems can be traced directly to poor maintenance. Following is an inspection schedule that may be helpful in setting up a preventive maintenance program. This schedule is not all-inclusive as inspection intervals will vary depending upon operating conditions.

Check around bearing covers, PTO covers and other machined surfaces. Also check for oil leakage on the ground before starting truck in the morning.
Every 10,000 Miles Maintenance
Check Oil Level
Note: Before checking the oil level, engine must be idling & transmission in neutral for at least 2 minutes. Lubricant temperature must be between 60 °F & 120 °F (15.5 °C and 48.8 °C).
Every 20,000 Miles Maintenance
