Power Train – Engine

Electronically controlled Caterpillar® engines with ACERT technology, modular radiator with 9 fins per inch, and an Electronic Control Module maximizes power to the cutting edge and exceptional haul road speed.

Power Train – Transmission

Planetary powershift transmission delivers excellent load capability. Redesigned front and rear axles accommodate wider brake shoes and drums. The neutral coast inhibitor and programmable top gear reduce wear while increasing machine performance.

Electronic Controls

Electronic controls improve machine response and provide advanced diagnostic capabilities that result in better machine availability. The Product Link option allows remote monitoring of location, machine system status, and alert indicators.

Operator Station

Convenient control placement and a comfortable work environment are keys to high productivity. Features include Single Lever Implement Control, an air seat suspension and improved instrumentation.


Superior structural design delivers state-of-the-art ride, capacity, and material control while assuring the durability and reliability customers expect from Caterpillar.

Scraper Bowl

Caterpillar Scraper bowls deliver large loads with better retention, excellent material flow, fast cycle times and high productivity. Relocating the implement valve to the draft tube improves access and serviceability.

Push-Pull Arrangement

For maximum production capability, Caterpillar offers an optional push-pull arrangement for the 627G, which allows two push-pull scrapers to act as a self-loading machine.

Auger Arrangement

Provides self-loading capability with the same wide material appetite as an open bowl machine.


The latest electronic monitoring systems, grouped service points, and rugged Caterpillar components simplify maintenance and minimize downtime. New two-piece access doors open easily and stay open for better access.

Customer Support

The best parts availability and the best service capability will help keep your equipment working.
