Proper lubrication measures are the key to a great all-around maintenance program. If the oil is no doing the job, or if the oil level is ignored, all the maintenance steps in the world space not walking to store the transmission running or assure long transmission life.Eaton Fuller transmissions space designed so that the internal parts operate in a bathtub of oil circulated through the motion of gears and shafts.Thus, all parts will it is in amply lubricated if these steps are closely followed:1. Maintain oil level. Check regularly.2. Readjust oil regularly.3. Usage the correct grade and kind of oil.4. Buy native a trustworthy dealer.

The usage of gentle EP equipment oil or multipurpose equipment oil is not recommended, however if these gear oils space used, be sure to adhere come the complying with limitations:Do not usage mild EP gear oil or multipurpose gear oil when operating temperatures are over 230ºF (110ºC). Numerous of these equipment oils, an especially 85W140, malfunction above 230ºF and coat seals, bearings and also gears through deposits the may reason premature failures. If these deposits room observed(especially a coating top top seal areas causing oil leakage), change to Eaton Roadranger CD5O transmission fluid, heavy duty engine oil or mineral equipment oil to guarantee maximum component life and to maintain your warranty through Eaton.(Also view “Operating Temperatures”.)Additives and friction modifiers are not encourage for usage in Eaton Fuller transmissions.

Proper Oil Level

Make certain oil is level with filler opening. Since you have the right to reach oil with your finger go not typical oil is in ~ the appropriate level. One inch of oil level is around one gallon the oil.

Draining Oil

Drain infection while oil is warm. To drain oil eliminate the drainpipe plug at the bottom the the case. Clean the drain plug prior to reinstalling.

Refilling

Clean case roughly filler plug and remove the plug from next of the case. Fill transmission to the level that the filler opening. If the transmission has two filler openings, fill to level of both openings.The exact amount of oil will count on the infection inclination and also model. Do not overfill; this will reason oil to be compelled out that the transmission.When including oil, types and brand of oil have to not be mixed because of feasible incompatibility.


Operating Temperatures

Recommended

– with engines the 350 H.P. And above with overdrive transmission

Required

– through engines 399 H.P. And over with overdrive transmissions and GCWs end 90,000 lbs.– v engines 399 H.P. And above and 1400 Lbs.-Ft. Or better torque– with engines 450 H.P. And 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, transmission oil coolers are not recommended v these gear oils since the oil cooler materials may be attacked by these gear oils. The lower temperature limit and also oil cooler restriction through these gear oils typically limit their success come milder applications.

Proper Lubrication levels as regarded Transmission surroundings AnglesIf the transmission operating angle is an ext than 12 degrees, improper lubrication can occur. The operating angle is the transmission mounting edge in the chassis add to the percent of upgrade (expressed in degrees).The chart illustrates the for sure percent of an upgrade on i beg your pardon the transmission deserve to be offered with assorted chassis mounting angles. Because that example: if you have a 4-degree infection mounting angle, climate 8 levels (or 14 percent of grade) is equal to the limit of 12 degrees. If you have actually a 0-degree mounting angle, the transmission deserve to be activate on a 12 level (21 percent) grade.Anytime the transmission operation angle that 12 levels is gone beyond 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 effect low oil levels can have top top safe operating angles. Permitting the oil level to loss 1/2″ listed below the filler plug hole reduces the level of great by around 3 levels (5.5 percent).
