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.
Bleed air tanks to remove water or oil.
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
Air System and Connections
Check for leaks, worn hoses and airlines, loose connections and loose capscrews. Check all capscrews in bolt circle of clutch housing for
Clutch Housing Mounting
Check Remote Control Linkage
- Check linkage U-joints for wear.
- Check for binding.
- Lubricate U-joints.
- Check for bushing wear.
- Check connections for tightness.
- Check and clean or replace air filter element.
Universal Joint Companion Flange
Pry upward against output shaft to check radial clearance in
mainshaft rear bearing.
Check splines for wear from movement and chucking action
of the universal joint companion flange.
Check for proper torque, 450 to 500 lbs. ft. on twin countershaft models.
Every 40,000 Miles Maintenance
Note: Inspection should be made according to the manufacturer’s specifications.
Check clutch disc faces for wear.
Check dampening action of clutch driven plate.
Remove hand hole cover and check axial and radial clearance in release bearing.
Check relative position of thrust surface of release bearing with thrust sleeve on push type clutches.
Every *50,000 Miles Maintenance
Change Transmission Lubricant
*Initial fill on new units should be changed at 5,000 miles
