Proper lubrication steps are the crucial to a good all-around maintenance program. If the oil is not doing that is job, or if the oil level is ignored, all the maintenance procedures in the world space not going to store the transmission running or assure lengthy transmission life.Eaton Fuller transmissions space designed so that the internal parts run in a bath of oil circulated by the motion of gears and shafts.Thus, all components will be amply lubricated if these actions are closely followed:1. Preserve oil level. Inspect regularly.2. Readjust oil regularly.3. Use the correct grade and form of oil.4. Buy from a dependable dealer.

The usage of gentle EP gear oil or multipurpose equipment oil is not recommended, however if these gear oils space used, be sure to adhere come the following limitations:Do not usage mild EP equipment oil or multipurpose equipment oil as soon as operating temperature are over 230ºF (110ºC). Many of these gear oils, particularly 85W140, malfunction above 230ºF and coat seals, bearings and also gears v deposits that may reason premature failures. If this deposits room observed(especially a coating top top seal locations causing oil leakage), readjust to Eaton Roadranger CD5O infection fluid, heavy duty engine oil or mineral gear oil to guarantee maximum ingredient life and to preserve your warranty v Eaton.(Also watch “Operating Temperatures”.)Additives and friction modifiers space not encourage for usage in Eaton Fuller transmissions.

Proper Oil Level

Make sure oil is level through filler opening. Since you deserve to reach oil with your finger go not average oil is at the ideal level. One customs of oil level is about one gallon the oil.

Draining Oil

Drain infection while oil is warm. To drainpipe oil remove the drain plug in ~ the bottom that the case. Clean the drainpipe plug prior to reinstalling.


Clean case around filler plug and also remove the plug from side of the case. Fill transmission to the level that the filler opening. If the transmission has actually two filler openings, to fill to level of both openings.The specific amount the oil will count on the transmission inclination and also model. Do not overfill; this will reason oil come be compelled out that the transmission.When adding oil, varieties and brands of oil have to not it is in mixed due to the fact that of feasible incompatibility.

Operating Temperatures

– with engines 399 H.P. And above with overdrive transmissions and also GCWs end 90,000 lbs.– v engines 399 H.P. And over and 1400 Lbs.-Ft. Or greater torque– v engines 450 H.P. And also above

With EP or Multipurpose gear Oil

Mild EP gear oil and also multipurpose gear oil space not recommended when lubricant operating temperatures are above 230ºF (110ºC). In addition, infection oil coolers are not recommended through these equipment oils because the oil cooler materials may be attacked by these equipment oils. The lower temperature limit and also oil cooler restriction through these gear oils typically limit their success come milder applications.

Proper Lubrication level as pertained to Transmission environment AnglesIf the transmission operating angle is more than 12 degrees, not correct lubrication deserve to occur. The operating angle is the transmission mounting angle in the chassis add to the percent of upgrade (expressed in degrees).The graph illustrates the for sure percent the an upgrade on which the transmission can be used with assorted chassis mounting angles. Because that example: if you have actually a 4-degree infection mounting angle, climate 8 levels (or 14 percent that grade) is same to the limit of 12 degrees. If you have a 0-degree mounting angle, the transmission have the right to be operated on a 12 degree (21 percent) grade.Anytime the transmission operating angle that 12 levels is gone beyond for an extended duration of time the transmission need to be equipped through an oil pump or cooler kit to ensure proper lubrication.Note on the graph the impact low oil levels can have top top safe operating angles. Enabling the oil level to fall 1/2″ listed below the filler plug feet reduces the degree of class by about 3 degrees (5.5 percent).
