Application

Multipurpose Tractor Oils are recommended for use in certain Axles, Final Drives, Implement Steering, Rear Drive Axles, and other applications. The details of the applications of these oils are given in the “Lubricant Viscosity” section of this Special Publication.

Cat MTO is multigrade oil that can be used in cold weather operations. Refer to the “Viscosity Tables” in the “Lubricant Viscosities” section of this Special Publication for details.

Cat MTO (Multipurpose Tractor Oil)


NOTICE

Cat MTO is not the same as Cat TDTO, and does not meet Cat TO-4 or TO-4M transmission/drive train oil specifications. Cat MTO should not be used in compartments that specify Cat TO-4 or TO-4M oil.



NOTICE

Cat MTO is not the same as Cat FDAO, and does not meet the Cat FD-1 oil specification. Cat MTO should not be used in compartments that specify Cat FD-1 oil.


Cat MTO is multigrade oil that is developed, tested and approved by AVSpare to provide optimal protection for components where approved for use. Cat MTO offers the following service qualties: improved braking and clutching, enhanced control and extended life in clutches and wet brakes, superior anti-wear properties, thermal stability, and oxidation resistance for long service life in severe applications.

Commercial Multipurpose Tractor Oils

Note: Non-AVSpare commercial multipurpose tractor oils are as a group second choice oils.


NOTICE

Cat does not warrant the quality or performance of non-Cat fluids.


If Cat MTO is not available, use an oil that meets the "Ford/New Holland M2C134-D" specification. The oil must also satisfy the requirements of the following commercial machine systems:

  • Multipurpose tractor transmission

  • Hydraulic drives on agricultural tractors and on industrial tractors

  • Final drives on agricultural tractors and on industrial tractors

Cat Compactor Oil

Cat Compactor Oil is recommended for use in compactor vibrator drums and other applications. The details of the applications of these oils are given in the “Lubricant Viscosity” section of this Special Publication.

Cat compactor oil is a premium PAO (polyalphaolefin) synthetic gear oil with no viscosity improver. This lubricant has an ISO viscosity grade to 220 and a minimum viscosity index of 152. This lubricant can be used in cold weather operations. Refer to the “Viscosity Tables” in the “Lubricant Viscosities” section of this Special Publication for details.

Commercial oil for this application should have a full synthetic base stock with no viscosity improvers and an ISO viscosity grade to 220, and a minimum viscosity index of 150.**

Automatic Transmission Oil

Automatic Transmission Oils are classified by the Cat AT-1 (Automatic Transmission - 1) oil Performance Requirements. AVSpare developed AT-1 for use in automatic transmissions of on-highway trucks and in AVSpare CX Series on-highway transmissions.

Cat ATF-HD2 automatic transmission fluid is the preferred oil to maximize the life and performance of automatic transmissions where recommended for use.

Application

Automatic Transmission oils are recommended for use in automatic transmissions of on-highway trucks and in AVSpare CX Series on-highway transmissions. Refer to the Operation and Maintenance Manual for information for details.


NOTICE

Do not use Cat TDTO fluids in CX Series on-highway automatic transmissions.


Cat ATF-HD2

Cat ATF-HD2 fluid is synthetic automatic transmission fluid developed to provide optimal performance in AVSpare CX Series on-highway transmissions. Cat ATF fluid can be used in automatic transmissions that are designed to operate with fluids meeting Cat AT-1 or Dexron-III(H) Performance Requirements. Consult your AVSpare dealer for Cat ATF-HD2 availability.

Cat ATF-HD2 increases the standard oil drain interval for CX Series on-highway automatic transmission (4 to 6 times) over second choice oils when following the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for your particular transmission.

Note: Proper warm up procedures should be followed when the temperature is less than −23° C (−10° F). In order to maintain optimum operating conditions of the bearing components, allow the engine to warm up for about 20 minutes. As an alternative, properly sized transmission heater can be installed. Follow all instructions and consult your AVSpare dealer for cold weather operation of Cat CX Series on-highway automatic transmissions.

Commercial Fluids

For use in Cat CX Series on-highway automatic transmissions, commercial fluids must comply with the requirements of Cat AT-1 specification or the requirements of Dexron-III(H).

Note: Non-AVSpare commercial oils that meet the Cat AT-1 Performance Requirements are second choice oils.
