Fuller Transmission Maintenance
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 a bath of oil circulated by the motion of gears and shafts. Thus, all parts will be amply lubricated if these procedures are closely followed:
1. Maintain oil level. Inspect regularly.
2. Change oil regularly.
3. Use the correct grade and type of oil.
The use of mild EP gear oil or multi-purpose gear oil is not recommended, but if these gear oils are used, be sure to adhere to the following limitations: Do not use mild EP gear oil or multi-purpose gear oil when operating temperatures are above 2300F. Many of these gear oils, particularly 85W140, break down above 2300Fand coat seals, bearings and gears with deposits that may cause premature failures. If these deposits are observed (especially a coating on seal areas causing oil leakage), change to Eaton Fuller Roadranger CD5O transmission fluid, heavy-duty engine oil or mineral gear oil to assure maximum component life and to maintain your warranty with Fuller.
