Lubrication
Lubrication
Proper lubrication procedure is the key to a good and complete maintenance program.
If the oil is not doing its job, or if the oil level is ignored, all the other possible maintenance procedures will not
be enough to keep the transmission running or to assure a long transmission life.
Eaton transmissions are designed so that all the internal parts operate in an oil circulating bath, created by the
motion of gears and shafts. Thus, all parts are properly lubricated if the following procedures are closely followed:
1. Maintain proper oil level by checking it regularly.
2. Change oil regularly following the maintenance interval chart.
3. Use the recommended grade and type of oil.
4. Buy the oil from a reputable dealer.
Oil change and level check
Periodic transmission oil change eliminates possible bearing failures, ring wear and seizures, since the products
from normal wear in service (tiny metal particles), which circulate in the transmission oil, are harmful to these parts.
In addition, the oil changes chemically due to the repeated heating and cooling cycles of a transmission in use.
As a general guide, the following chart provides lubricant oils and maintenance interval recommendation for oil
level check and oil change.
CAUTION!
Always follow the vehicle manufacturer maintenance recommendation, which prevails
over this chart.
NOTE:
•
The oil must be changed on the recommended mileage or time interval, whatever occurs first.
•
Daily, check the transmission for lubricant oil leaks and make the proper repairs when necessary.
• During oil level inspections, it is recommended to inspect the sensors at the rear of the transmission
(rear speed and rotation sensor). If the presence of debris is observed, clean the parts. Do not use
chemicals. During oil changes, repeat this process including the front sensor.
