Proper Lubrication is the key to long transmission life.

Proper lubrication procedures are the key to a good all-around maintenance program. If the oil is not doing its job, or if the oil level is ignored, all the maintenance procedures in the world are not going to keep the transmission running or assure long transmission life. Eaton Fuller Transmissions are designed so that the internal parts operate in an oil circulating bath created by the motion of the gears and shafts.

Thus, all parts are amply lubricated if these procedures are closely followed:

1. Maintain oil level.

2. Follow maintenance interval chart.

3. Use only recommended lubrication.

4. Buy lubricant from a reputable dealer.

checking oil level in Eaton Fuller transmission

Note: Before checking the oil level, the 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).

Proper Oil Level: Make sure oil is level with the filler opening. Because you can reach oil with your finger does not mean oil is at the proper level. One inch of oil level is about one gallon of oil.
