Powertrain

Cat^® axles provide high durability, low sound levels, and traction control on uneven or poor terrain. Caterpillar offers a wide variety of models and load capacities. Caterpillar's heavy-duty design withstands the type of shock loading that occurs during all-terrain operation.
 

• Heavy-duty design features stronger gears and bearings for durable performance.
• Duo-cone metal face seals between the axle shafts and housing keep oil in and contaminants out.
• Oil-disc brakes are adjustment free and fully enclosed.
• Optional front and rear limited-slip differentials provide maximum traction in poor underfoot or uneven floor conditions.
• A No-SPIN differential is available to deliver maximum traction in low-traction or inconsistent ground conditions.

OEMs in industries as varied as forestry, locomotive, material handling, agriculture and mining rely on Caterpillar to design and manufacture their transmissions. We develop each transmission to integrate with other powertrain systems and components - including the engine, axle, electronics, hydraulics, and operator interface - to deliver maximum power while optimizing the performance of the complete powertrain system.

Leveraging decades of service to the agricultural and related industries, Caterpillar has developed solutions to the challenges facing many of today's original equipment manufacturers. Working with OEMs that service the agricultural industry, Caterpillar produced a new line of high capacity, high efficiency direct-drive transmissions.

The planetary final drives used in Caterpillar® wheel loaders, off-highway trucks, track-type tractors, wheel tractor scrapers and log skidders are available to Original Equipment Manufacturers.

They feature:
• Single, double and triple reduction configurations
• Torque inputs from 2,500 to 25,000 ft. lbs.. (3,390 to 33,900 N.m)
• A wide selection of gear ratios
• Self lubrication
• Longlife metalface seals
• Compact design
