•Machine systems working together in the harshest environments
•Diagnostic programs are available to monitor machine health and maintain uptime
MACHINE LIFE. The 993K is designed to meet customer rebuild requirements and a high hour structure life. This is accomplished through design emphasis put on key components:
Caterpillar Designed Components.
Components used to build Cat Wheel Loaders are designed and manufactured to Caterpillar quality standards to ensure maximum performance even
in extreme operating conditions.
•Linkage. The 993K features the field proven Z-bar linkage design with new maintenance-free sleeve bearing (SB) pins. A key benefit of the SB pins is when maintenance is required, customers can schedule change out of pins on a planned maintenance day. Design of the SB pins allows this planned downtime due to the fact it has low risk of consequential damage. In addition, significant growth in width for support of the Z-bar linkage further increases strength and durability.
•Cat Planetary Power Shift Transmission. The 993K has increased strength and reliability by utilizing a similar planetary gear group used in the Cat 994F.
•Front and Rear Frames. The front and rear frames are spread further apart for improved bearing life. A key
differentiator from competitive machines is the box section rear frame and four plate loader tower. The box section absorbs torsional forces generated in a loading cycle, maintaining alignment for hitch pins and drive line. The fourplate loader tower resists shock and torsional loads maintaining hitch and loader linkage pin alignment.
•Axle Shaft Service Brake. Sharing similar components with the Cat D9R, this service brake provides improved retarding capabilities and better braking ability. Positive oil flow and brake oil cooling result in improved brake disc durability. Additionally, the 993K third gear run out stopping distance
is greatly reduced.
4
• Next Generation Modular Radiator (NGMR). Utilizing 14 parallel flow system modular cores, the NGMR increases cooling performance by only drawing cooler ambient air through the radiator system.
PROVEN ENGINE TECHNOLOGY.
The 993K utilizes the Cat® C32 engine which fully meets U.S. EPA Tier 2/EU Stage II emissions requirements.
This Mechanically Actuated Electronically Controlled Unit Injection (MEUI) diesel engine shares a common platform with the Cat 777F, 854K, 992K and Dll.
DIAGNOSTIC PROGRAMS.
Monitoring product health is key to maintaining reliability of any equipment. Many programs are available on the 993K, both as standard and optional features, to help you track machine condition.
VIMS Monitoring System with Enhanced Display. Monitoring over 100 machine parameters, VIMS records these parameters for maintaining and optimizing the machine. VIMS features System Events and Data Events, giving notification from machine malfunction to changes in pre-programmed machine settings.
Product Link. Product Link is a state- of-the-art satellite technology based product that provides an information flow between machine on-board systems and the Caterpillar operations center. Multiple types of information can be collected and tracked – from machine location and service meter hours to health and productivity information.
Equipment Manager. With a subscription to Equipment Manager through the
Cat Dealer StoreFront, the information collected through Product Link can be transmitted to a computer. With fast, easy-to-access machine information, you can optimize asset utilization, reduce security risks, improve maintenance management and implement beforefailure repair strategies.
S·O·SSM Services. Keep minor repairs from becoming major ones and avoid complete failures. By regularly taking samples from the ports provided, your Cat dealer tracks wear of components and parts, oil performance and oil condition and uses that data to predict wear-related problems before they happen.

Left Pedal
Impeller Clutch Torque Converter (ICTC)/Rimpull Control System.
Mixing new with a current validated system, customers can maintain hydraulic balance while digging and loading by utilizing the ICTC/Rimpull Control System. The ICTC enables the operator to finely modulate rimpull for smooth machine operation.
Steering System. Load sensing steering reduces the demand on the hydraulic system when steering is not activated. By delivering only the power draw that is needed, engine power is reserved for productive work.
Double Reduction Final Drives.
The 993K final drives are built off the D11 design platform and tailored for wheel loader applications. The double reduction final drives enable the increase in rimpull. Additional benefits include significantly reducing power train stresses resulting in longer overall power train life, durability and ease of service.
Linkage Pins. The 993K features durable, service-free,oil filled and sealed-for-life Cat Sleeve Bearing (SB) pins. The SB pins eliminate the need for daily greasing of the front linkage and requires no routine maintenance for continued uptime.

Cat Planetary Power Shift Transmission. The 993K planetary power shift transmission assists in the increased rimpull. This transmission is electronically controlled and features three forward and three reverse speeds.
Transmission features include:
•Integrated shifting/steering control with F/N/R rocker switch and upshift/downshift switches.
•Transmission clutch control for improved shift quality, component life and operator comfort.
•ICTC for improved rimpull control and transmission clutch durability.
Truck Pass Match. It is not always about working harder, but working smarter – optimize the wheel loader to the trucks. This is accomplished through even passes when loading and optimizing operation for efficiencies. The 993K was developed to optimize pass match with key trucks in this size class and job site requirements.

Transmission Lockout Switch (6).
The transmission lockout switch does not allow the transmission to shift out of neutral, even if running. This feature is designed for service procedures that requires machines to be running but need the transmission disabled for added safety.
SAFETY IN OPERATOR ENVIRONMENT.
The operator and safety go hand-in-hand. Many features that enhance operator comfort also aid in keeping your operator safe from lowering noise levels to design features that lower vibration and repetitive motion. Key standard features that aid operator safety include low effort implement controls integrated with the seat for ease of adjustment by the operator, front windshield cleaning platform with handrails and a seat belted trainer’s seat for convenient operator training on the job site. Additional safety features include a cab filtration system that removes dust and debris from the cab air. Optional for dusty applications is a cab pre-cleaner that reduces the amount of dust prior to reaching the cab filter.
