Final drives are the muscle behind your machine’s movement. These powerhouses translate engine power into the torque your machine needs to move. Thompson Machinery offers you the components you need to keep operations running. Genuine Cat® components are engineered to match the exact torque and braking specifications of your machine, ensuring you get continuous power and control.
Precision Components for Every Machine
Whether you need a complete replacement or a specific repair kit, we have the final drive parts for heavy equipment to do the job right. As official Cat dealers, we offer complete parts availability and fast sourcing through our extensive network. Our components are built for superior durability, reliability and performance in heavy-duty applications.
The final drive is the last stage of a machine’s drivetrain. They convert high-speed, low-torque engine output into the low-speed, high-torque force required for tasks like heavy lifting and digging. Cat machines use four types:
- Bull Gear single reduction
- Bull Gear double reduction
- Planetary single reduction
- Planetary double reduction
Final Drive Groups and Motors
We have final-drive group kits without a motor to restore your existing group to peak efficiency. This gearbox assembly is designed to be a plug-and-play unit with the separate motor, delivering the powerful force needed for heavy work.
Our general-duty final drives are cost-effective, durable options for lighter applications. They feature robust, interchangeable components that reduce wear, offering proven performance and lower operating costs.
Assemblies and Gear Kits
Our roller bearing assemblies help maintain proper alignment and ensure durability. They feature tapered rollers within inner and outer rings to handle massive radial and thrust loads. This design improves wear life and system performance by reducing friction in the drivetrain or undercarriage. The kits simplify maintenance by offering precisely matched, application-specific parts labeled for easy identification.
We offer a wide range of gear kits with all the parts needed to perform specific maintenance tasks, including:
- Primary kits: This kit is a complete replacement set that includes gears and essential components.
- Planet gear: This single-part-number package extends mating gear life and provides exceptional performance in the planetary set.
- Mount kit: This kit includes the components needed to service parking brakes, including all necessary seals, O-rings, washers and springs.
- Lining kit: This package provides the essentials to repair internal systems, including bolts, nuts, linings and caps.
