ENGINE AR 1W1440 - Caterpillar

in Caterpillar transmissions. TDTO has passed the requirements for the Caterpillar TO-4 oil specification which includes the frictional requirements and gear wear requirements. TDTO is offered in different viscosity grades, including SAE 50, for maximum component service life at high ambient temperatures and heavy duty cycles.For maximum transmission service life and performance, Caterpillar recommends: Caterpillar Transmission/Drive Train Oil (TDTO) Contact your Caterpillar dealer for part numbers and available container sizes.
This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine service life will result.Do not use Caterpillar Gear Oil (GO) in marine transmissions. Gear Oil can cause seal material to fail and possibly leak. Gear Oil also may not be compatible with friction materials and can reduce transmission efficiency.
Multi-grade oils are not currently blended by Caterpillar for use in transmissions. Multi-grade oils which use high molecular weight polymers as viscosity index improvers lose their viscosity effectiveness by permanent and temporary shear of the viscosity index improver. Therefore, multi-grade oils are not recommended for transmissions. The Caterpillar TO-4 specification does include a test for multi-grade oil shear stability. Multi-grade oils with adequate shear stability may be available in the future.Commercial Transmission/Drive Train Oils
If Caterpillar Transmission/Drive Train Oil is not used, commercial oils meeting the Caterpillar TO-4 specification must be used in Caterpillar marine transmissions:* TO-4 Specification Oils, single grade onlyCommercial Marine Transmissions
For marine transmissions which are not manufactured by Caterpillar, refer to the marine transmission or vessel OEM lubrication recommendations.S O S Oil Analysis
Caterpillar's Scheduled Oil Sampling (S O S) Oil Analysis should be a part of an engine's overall maintenance program. The S O S program monitors the engine and transmission through used oil analysis. The oil analysis measures wear metals and oil condition. Deviations from established limits or trend lines can diagnose an impending problem before the problem becomes apparent, costly, and destructive.See your Caterpillar dealer for more information regarding S O S Oil Analysis and how the program can help you manage your engine and transmission.Engine Lubricant Recommendations Summary
To achieve all the performance that was built into a Caterpillar engine, follow these guidelines:* Select the proper Caterpillar oil or commercial oil that meets the API specifications* Select the proper oil viscosity based on the applicable Lubricant Viscosities chart* Replace the engine oil and oil filter(s) at the intervals specified in the Operation and Maintenance Manual* Perform maintenance according to the Operation and Maintenance ManualCaterpillar Lubricating Grease
Caterpillar provides grease for a variety of applications and extreme temperature conditions. The descriptions of these products follow.Contact your Caterpillar dealer for part numbers and available container sizes. One grease may be incompatible with another grease. When using commercial grease, make sure the grease is compatible with the grease used in your system, or make sure to purge the system. Contact your supplier regarding grease compatibility questions.Multipurpose Grease
Multipurpose Lithium Complex Grease (MPG)
MPG is a NLGI No.2 general purpose lithium complex grease for light to medium duty applications. MPG has good high temperature characteristics,
