COOLING SYSTEM, in the Maintenance Manual.
Fuel Tank Diesel Fuel Oil with maximum sulphur 0.5%. DIN EN590
Differential Multipurpose Extreme Pressure type gear oil meeting SAE 80W-90
Planetary Gears MIL-L-2105C Specifications (No Zinc Additive). at ambient temperatures of -18° to 32° C
Power Takeoff See Note 4*.
Grease Fittings Multipurpose Extreme Pressure Lithium Grease (which No. 2 Consistency
may or may not contain 'Molybdenum'), with a typical
melting point of 190° C.
Drivelines Multipurpose Extreme Pressure Lithium Grease (without No. 2 Consistency
Steering Column 'Molybdenum'), with a typical melting point of 190° C.
Wheel Bearings
Air Conditioning Polyalklene Glycol (PAG) ISO46
Compressor Compressor Lubricating Oil - Low Viscosity SP 10
Ride Cylinders Hydraulic oil meeting MIL-L-2104B Specification. SAE 10W
(Nitrogen/Oil)
Hydraulic System Hydraulic Transmission Oil meeting Specification SAE 10W
EMS19058. See Note 5. at ambient temperatures of -18° to 32° C
SAE 30W
at ambient temps of 32° C and above
Note: Capacities given are approximate. Work to dipstick, sight gauges or level plugs. Use table in conjunction with
'Recommended Lubricants' table.
Note: *Use of the correct transmission oil type is essential to prevent damage to the transmission and maintain correct
operation. In trucks which are TranSynd RD filled, use only TranSynd RD. Similarly for trucks filled with EO, use only EO.
Note 1 - Consult your lubricant supplier for the correct viscosity of lubricant to use when ambient temperatures are
consistently above or below those listed.
Note 2 - Cummins Engine Co. do not recommend any specific brand of engine oil but the use of oils that meet API categories.
Cummins recommend use of only the multi-graded viscosity oils shown for the various ambient temperatures listed.
Note 3 - Operation below the minimum temperatures listed for the oil used without proper preheat or warm-up results in
greatly reduced transmission life. If auxiliary heating is available, preheat the oil to the minimum temperature limit. If not
available, run the engine at part throttle with the transmission in neutral to raise the fluid temperature.
Note 4 - If rear axle has limited slip differential, an EP oil with limited slip additives should be used because using standard
SAE 90 oil may result in very loud noise and jerking of the wheels when driving slowly round sharp corners.
Note 5 - Typical SAE 10W oils complying with Specification EMS19058 are:
KUWAIT TO4 TEXACO TEXTRAN TOTAL TRANSMISSION AC
SHELL DONAX TC MOBILTRANS HD BP AUTRAN 4
ESSO TORQUE FLUID CASTROL TFC
Other lubricant suppliers may have comparable products and should be consulted for confirmation.
