Proper lubrication actions 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, every the maintenance actions in the world space not going to store the transmission running or assure long transmission life.Eaton Fuller transmissions are designed so that the internal parts operate in a bathtub of oil circulated by the motion of gears and shafts.Thus, all parts will be amply lubricated if these steps are closely followed:1. Preserve oil level. Examine regularly.2. Change oil regularly.3. Use the exactly grade and kind of oil.4. Buy from a reliable dealer.

The usage of mild EP gear oil or multipurpose gear oil is no recommended, but if these gear oils are used, be sure to adhere come the adhering to limitations:Do not usage mild EP equipment oil or multipurpose equipment oil when operating temperatures are over 230ºF (110ºC). Plenty of 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 are observed(especially a coating top top seal areas causing oil leakage), change to Eaton Roadranger CD5O infection fluid, heavy duty engine oil or mineral gear oil to assure maximum ingredient life and to maintain your warranty with Eaton.(Also check out “Operating Temperatures”.)Additives and friction modifiers space not encourage for use in Eaton Fuller transmissions.

Proper Oil Level

Make sure oil is level v filler opening. Due to the fact that you have the right to reach oil with your finger walk not typical oil is in ~ the proper level. One customs of oil level is about one gallon the oil.

Draining Oil

Drain transmission while oil is warm. To drain oil remove the drain plug in ~ the bottom the the case. Clean the drainpipe plug before reinstalling.

Refilling

Clean case roughly filler plug and remove the plug from next of the case. Fill transmission to the level of the filler opening. If the transmission has actually two filler openings, fill to level of both openings.The exact amount that oil will depend on the transmission inclination and model. Execute not overfill; this will cause oil to be required out that the transmission.When including oil, species and brand of oil need to not be mixed since of possible incompatibility.


Operating Temperatures

Recommended

– through engines that 350 H.P. And over with overdrive transmission

Required

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


With EP or Multipurpose equipment Oil

Mild EP equipment oil and also multipurpose gear oil are not recommended as soon as lubricant operation temperatures are over 230ºF (110ºC). In addition, infection oil coolers space not recommended through these gear oils because the oil cooler materials may be struck by these equipment oils. The reduced temperature limit and also oil cooler restriction with these equipment oils generally limit their success come milder applications.

Proper Lubrication levels as regarded Transmission environment AnglesIf the transmission operating angle is an ext than 12 degrees, not correct lubrication can occur. The operation angle is the transmission mounting edge in the chassis plus the percent of update (expressed in degrees).The graph illustrates the safe percent of an upgrade on which the transmission deserve to be used with various chassis mounting angles. For example: if you have actually a 4-degree transmission mounting angle, then 8 degrees (or 14 percent of grade) is equal to the border of 12 degrees. If you have a 0-degree mounting angle, the transmission deserve to be activate on a 12 degree (21 percent) grade.Anytime the transmission operating angle the 12 degrees is exceeded for one extended duration of time the transmission have to be equipped through an oil pump or cooler kit to ensure suitable lubrication.Note ~ above the graph the result low oil levels deserve to have top top safe operation angles. Permitting the oil level to loss 1/2″ below the filler plug feet reduces the degree of great by about 3 levels (5.5 percent).
