EatonTransmission Lubricant Maintenance Procedures

Proper Lubricationis ImportantOne of the keys to long and effectivecomponent life is proper lubrication. Ifyour lubricant is not doing its job,other maintenance procedures will beineffective in assuring vehicleperformance.

Vital components will be properlylubricated when the followingmaintenance procedures are closelyfollowed:

Inspect for oil leaks regularly Maintain proper oil level Change oil at the proper drain

interval*

Use correct lubricant gradeand type

Purchase an Eaton approvedsynthetic lubricant forextended drain intervals

For either new or rebuilt components,mineral lubricants must be changedwithin the first 10,000 kilometres ofoperation. When a transmission isfactory-filled with Eaton approvedsynthetic lubricant, the initialdrain interval is unnecessary.

Mixing of Oil TypesCAUTION: Never mix engine oils& gear oils in the sametransmission.

Engine oils and gear oils may not becompatible; mixing can cause break-down of the lubricant and affectcomponent performance. Whenswitching between types of lubricants,all areas of each affected componentmust be thoroughly drained.

Aftermarket AdditivesAdditives and friction modifiersmust not be introduced.

*Oil analysis is required to determine exact oil change interval which can vary depending on application.

**Not approved for automated transmissions or manual transmissions above 1850 lbs.ft. If oil filter fitted, the filter should be changed at every oil change interval or if visually damaged/rusted.

Eaton Approved Synthetic Oil

Roadranger CD-50Oil SamplingOil samples should be taken from centre of the transmission withoil at operating temperature using a suitable syringe. Oil samplingto take place at 80,000 - 100,000kms.

Eaton Transmission Lubricant Maintenance Procedures

Proper TransmissionLubrication LevelMake sure transmission oil is level withthe bottom of the fill opening. Being ableto reach the oil with your finger does notmean the oil is at the proper level. (Onheavy duty transmissions, one inch(25.4mm) equals about 4.5 litres of oil.)

If the transmission operating angle ismore than 12 degrees, improperlubrication can occur. The operating angleis the transmission mounting angle in thechassis plus the grade (expressed indegrees).Anytime the transmission operating angleof 12 degrees is exceeded for an extendedperiod of time, the transmission must beequipped with an oil pump or cooler kit toensure proper lubrication.

Regular Oil ChangesDrain the transmission while oil is warm.Clean housing around fill plug andremove plug from housing side. Fill thetransmission to the level of the fillopening. The exact amount of oil dependson the transmission inclination andmodel. Do not over-fill. Clean plug beforereinstalling.

Regular InspectionRecommended transmission lubricationinspection intervals:

HIGHWAY APPLICATIONS:

Check fluid levels and inspect forleaks every 20,000 kilometres.

ON-OFF HIGHWAY APPLICATIONS:

Check fluid level and inspect for leaksevery 50 hours.

Operating TemperaturesTransmissions must not be operated attemperatures above 120C.

In all cases, cooler must havesufficient capacity to maintain oiltemperatures below 120C atworst case operating conditions.

Operation at temperatures above 120Ccauses loaded gear tooth temperatures toexceed 170C which will ultimatelydestroy the heat treatment of the gears.While occasional short termtemperatures above 120C may notcause damage, it should be regarded asa warning of inadequate cooling. If theelevated temperature is associated withan unusual operating condition that willrecur, a cooler should be added, or thecapacity of the existing systemincreased.The following conditions in anycombination can cause operatingtemperatures over 120C: Operating consistently at slower

speeds. High ambient temperatures. Restricted air flow around

transmission and cooler. High horsepower.Transmission coolers must be used toreduce operating temperatures when theabove conditions are encountered.

Oil Cooler ChartTransmission Oil Coolers are:Recommended:With engines of 350 H.P. (265 kW) and above.Required:With engines 399 H.P. (300 kW) and above and GCMs over 40 tonnes.With engines 399 H.P. (300 kW) and above and 1400 lbs. ft (1900 Nm).With engines 450 H.P. (335) and above.With engines 1500 lbs. ft (2030 Nm) and above.
