LUBRICANT SPECIFICATIONS Allison Transmission Lubrication Lubrication Change and Inspection Spicer Transmission Lubrication Recommended Lubricants The lubricants listed below are recommended, in order of preference, for use in all Spicer mechanical transmissions, auxiliaries, and transfer cases. Do not use extreme pressure additives such as those found in multipurpose or rear axle-type lubricants. These additives are not required in Spicer transmissions, and may in some cases create transmission problems. Multipurpose oils, as a group, have relatively poor oxidation stability, a high rate of sludge formation, and a greater tendency to react with or corrode the steel and bronze parts.
Refer to your transmission manual (furnished separately) for lubrication information. It is extremely important to use the proper lubricants and maintain the correct oil levels in Spicer units. This will ensure proper lubrication and operating temperatures in these units. Refer to the Allison Transmission manual for servicing information. 5 5-50 Y53-6077-1B1 (03/17) Type Grade (SAE) Ambient Temperature Heavy Duty Engine Oil MIL-L-2104D or MIL-L-46152B, API-SF or API-CD (MIL-L-2104B or C or MIL-L-46152 designations are acceptable) 30, 40, or 50 Above 0° F (-18° C) 30 Below 0° F (-18° C) Mineral gear oil (R and O type) API-GL-1 90 Above 0° F (-18° C) 80 Below 0° F (-18° C)
