Power Train

Power Train
Integrated, electronically controlled systems, deliver smooth reliable performance with reduced operating costs.

Smooth Shifting Transmission.
The 16M combines several key innovations to ensure smooth, powerful shifts throughout the gear range.

Electronically Controlled Shifting.
The full Electronic Clutch Pressure Control (ECPC) system optimizes inching modulation and smooths shifting between all gears and directional changes. This provides outstanding control and also extends the life of the transmission by reducing stress on the gears.

Load Compensation.
This standard feature ensures consistent shift quality regardless of blade or machine load.

Controlled Throttle Shifting.
This standard feature helps to smooth directional and gear changes without use of the inching pedal.

Engine Over-Speed Protection.
Helps protect the transmission and extend component life by preventing downshifting until a safe travel speed has been established.

Power Shift Countershaft Transmission.
Designed and manufactured specifically for the 16M motor grader, the direct drive countershaft transmission is matched with the powerful Cat C13 engine to maximize power to the ground.

Modular Rear Axle.
The 16M incorporates a bolt-on modular rear axle design, which offers easy access to differential components, improves serviceability and contamination control, and lowers maintenance time and operating costs. The result is a rugged machine you can rely on for years to come.


Front Axle.
The Caterpillar® sealed spindle keeps the bearings free from contaminants and lubricated in a light-weight oil (1). This durable, low-maintenance design reduces your owning and operating costs. Two tapered roller bearings (2) support the wheel spindle. The Cat “Live Spindle” design places the larger tapered roller bearing outboard where the load is greater, extending bearing life.

Gear Selection.
Eight forward and six reverse gears give the operator a wide operating range. The specifically designed range of gears ensures maximum productivity in all earthmoving applications.

Programmable Autoshift.
The operator can easily customize various shift parameters through Cat Messenger to match the specific application requirement. This optional feature automatically shifts the transmission at optimal points so the operator can focus on the work, improving safety, productivity and ease of operation.

Inching Pedal.
Allows precise control of machine movements in any gear with low pedal effort and excellent modulation, critical in close-quarter work or finish grading.

Hydraulic Brakes.
The oil bathed, multidisc service brakes are hydraulically actuated (1), providing smooth predictable braking and lower operating costs. With brakes located at each tandem wheel, the 16M offers the largest total brake surface area in the industry (2), delivering dependable stopping power and longer brake life.

Brake Serviceability and Reliability.
An easily accessible brake wear indicator/ compensator system (3) maintains consistent brake performance and indicates brake wear without disassembly. This system cuts service time and extends brake service life.


Parking Brake.
The spring-applied, hydraulically released multi-disc parking brake can be easily serviced without transmission removal to reduce operating cost. A sealed, oil-cooled design extends component life and reduces the need for service.
