The Cat® C18 engine with ACERT® Technology is U.S. EPA Tier 3 and EU Stage III compliant. It features increased horsepower and efficient fuel management for quick response, high productivity and exceptional service life. A sculptured cylinder block provides greater strength and is lighter weight.
New and current features are built into the 988H and depending on application requirements can provide up to 15 percent less fuel burn.
The Cat® 988H Wheel Loader Fuel Management System delivers solid productivity and fuel savings of as much as 15 percent in truck loading and more in load and carry operations. By lowering engine speed during all but the digging portion of each cycle, the proprietary system minimizes impact on productivity while gaining significant fuel savings.
If an operator is not actively operating the 988H for a period of time, the AIK system will temporarily reduce the engine speed to save fuel. After an automated engine speed reduction, the system will automatically resume the engine speed to the previous setting when the operator engages the implement control pod of the F-N-R switch or the STIC Steer.
This new feature will automatically shutdown the engine after the machine has been in a safe idling state for an extended amount of time. The operator in the cab will be audibly and visually warned before the shutdown occurs.
ICTC combined with the RCS allows the operator maximum flexibility in the modulating rimpull.
VSC matches transmission shifting patterns to machine application requirements, by shifting at lower engine rpms. This both improves shift quality and fuel efficiency in certain applications.
Combining the use of robotic welding and castings in critical high-stress areas, more than 90 percent of the 988H structure is robotically-welded to provide highly consistent welds and increased strength. Castings are also used in several areas to increase strength by helping to spread the loads and reduce the number of parts.
Highly engineered and a field-proven combination, the 988H uses high-strength plates and castings which distribute loads and increases structure robustness. A key differentiator from other manufacturers' machines is the box-section rear frame and box-shaped loader tower. The box section absorbs torsional forces generated in a loading cycle, maintaining alignment for hitch pins and driveline. The box-shaped loader tower resists shock and torsional loads, maintaining hitch and loader linkage pin alignment, maximizing pin life.
The 988H features the revolutionary box boom linkage design. Known for its durability, the 988H box boom linkage has high strength castings in pin joint areas that resist twisting and minimize stress. A B-pin bucket mount is placed at a height to prevent bucket healing due to better stress distribution from bucket to boom. Additionally, a four-hinge plate bucket design is utilized to increase bucket durability.
A comfortable operator is a productive operator, which is why Caterpillar has designed the 988H with a best in-class working environment for this size wheel loader class.
The new Payload Control System (PCS) 3.0 is designed to help the 988H owners and operators manage truck payloads and produce accurate records of material movement. This advanced electronic control system is designed for on-the-go weighing. With the new PCS 3.0 system, accuracy is now ±1 percent, has improved interface, can record up to 1,000 trucks and can store 25 different materials for continued record accuracy of job site production.
Operators can easily set the dump height, return to dig/carry or bucket angle from the comfort of the cab. Standard, in-cab programmable kickouts are located in the upper left panel. This feature provides more flexibility and improved productivity when the job requires load and dump target heights.
With the 988H update, Caterpillar introduces a new bucket offering ranging from 6.4 m³ (8.3 yd³) to 7.7 m³ (10 yd³). The new buckets offer design enhancements to include larger throat opening, increased floor length and improved setback angle. These design enhancements yield improved bucket fill factor and load retention in carry position.
These buckets with bolt-on segments are available in 6.4 m³ (8.3 yd³) to 7.7 m³ (10 yd³). Each accepts up to two sets of sidebar protectors (4), featured shouldered, double-strap adapters, easily changed bolt-on segments and several tip options.
Available in 6.3 m³ (8.2 yd³) Straight Edge Rock, as well as 7.0 m³ (9.2 yd³) and 7.7 m³ (10 yd³) General Purpose configurations. The General Purpose bucket features double strap adapters and accepts two sets of sidebar protectors, bolt-on segments and tips. The General Purpose bucket is available with bolt-on cutting edge, bolt-on adapters or bolt-on adapters with segments.
This bucket is available with a 6.4 m³ (8.33 yd³) capacity and is recommended for use in face loading where abrasion and moderate impact is encountered. This bucket features additional wear protection items including independently attached edge and adapter covers, additional liners and wear plates, one set of sidebar protectors and a thicker base edge.
This 6.4 m³ (8.33 yd³) capacity bucket is recommended for use in face loading where moderate abrasion and high impact is encountered. It features additional wear protection items including four sidebar protectors, thicker base edge and adapters, additional liners and wear plates and bolt-on half arrow segments.
The 988H is designed to ensure minimal downtime through ground level or platform access, grouped service points, and attention to key serviceable areas on the machine.

At Caterpillar, we have designed the 988H with your most important asset in mind - People. Drawing from a history of technological advancements and practical wisdom, you can be assured that your people are protected while working in, on or around the 988H Wheel Loader.
Good visibility, whether it be positioning to the truck or watching for people and vehicles on the site, the 988H offers a number of standard and optional features to enhance job site visibility. Standard and optional features include articulated wiper/washer system with intermittent features, optional rear vision camera, optional high intensity discharge (HID) lights, optional warning beacon and optional turn signals.
Getting on and off the machine is one of the leading causes of injury on a job site. The 988H has a number of features to ensure your operator gets safely on and off the 988H. The 988H includes primary and secondary stairwell exits, punch stamped tread plates located throughout the machine, ground level night time stairwell light switch, full perimeter railings on the upper platform, side platform emergency egress and toe kicks and optional roading fenders.
Daily and routine maintenance should not pose a safety hazard to your operator or service technician. With the 988H, design efforts were taken to group service points with convenient access. As seen in the serviceability section, all service points are at ground level or platform access to maintain three points of contact, and a number of disconnect switches are available to ensure the 988H is static during service.
For the 988H, the operator and safety go hand-in-hand. The 988H offers many features that enhance operator comfort and aid in keeping the operator safe. In the cab, all controls are ergonomically designed for easy adjustment, low-effort and easy to reach controls minimize repetitive motion and potential strains. With a cab filtration system, low operator sound and optional features such as ride control or secondary steering, all effort has been made to protect the operators from environmental elements that can cause issues with their health or well-being.
