[. . . ] 6 Structures Superior structural design delivers stateof-the-art ride, capacity, and material control while assuring the durability and reliability customers expect from Caterpillar. 7 Push-Pull Arrangement (637G only) For maximum production capability, Caterpillar offers an optional push-pull arrangement for the 637G, which allows two push-pull scrapers to act as a selfloading machine. 12 Auger Arrangement Provides self-loading capability with the same wide material appetite as an open bowl machine. 13 Quick loading, high travel speeds and the ability to load and dump on the run yield ® fast cycle times, allowing Caterpillar Wheel Tractor-Scrapers to consistently deliver high productivity. 2 Operator Station Convenient control placement and a comfortable work environment are keys to high productivity. [. . . ] For operators requiring additional damping, dual shock absorbers in the seat suspension are available. Increases legroom a full 89 mm (3. 5 in. ), and reduces knee contact. Standard air conditioning system with relocated louvers enhances airflow in the cab. Convenient storage location includes space for a lunch box and first aid kit. The cab also has a cup holder as well as an ashtray. The redesigned hood has sloped corners to maximize visibility while accommodating the low emissions engine. The redesigned hood and front shroud are wider to enclose the air-to-air aftercooler (ATAAC), ether starting aid, and lights. The exhaust is located at the back of the hood for good visibility to the right side. Features a new quad-gauge layout showing engine coolant temp, transmission/torque converter oil temp, fuel level, and system air pressure. The 637G tachometer can monitor either front or rear engine speeds. Once the 637G tractor engine has been started, the operator can start the rear engine from inside the cab using a switch on the instrument panel. The rearpowered scraper now has two ECMs rather than three. The ADEM A4 controller monitors air filter restriction. If the restriction exceeds the allowable limit, it alerts the operator by sending a message to the Electronic Monitoring System (EMS III). The ADEM A4 controller activates the ether injection system during engine cranking to enhance cold weather starting. At high altitudes the system automatically de-rates fuel delivery as a function of barometric pressure sensed by the system's atmospheric pressure sensor. 10 Scraper Bowl Designed for optimum loading, material retention and ejection. Redesigned Bowl. The redesigned bowl minimizes falling material lodging between the bowl and the draft arm, which can result in premature wear. The modifications also provide better load retention on level ground or traversing down a grade. Bowl capacity has been increased by 3 yd3 (2. 3 m3), allowing more material to be moved. · · Low-profile bowl design offers less resistance to incoming materials. Cellular construction adds strength and dent resistance to bowl sides and floor. Bulldozer Ejection System. Cat bulldozer ejection system offers constant spreading control with minimal material carry back. [. . . ] Diagnostic programs such as S·O·SSM Analysis and Coolant Sampling and Technical Analysis help avoid unscheduled repairs. Your Cat dealer can help you evaluate the cost involved so you can make the right choice. 15 Engine Tractor Engine Scraper Engine Cat C18 ACERTTM Cat C9 ACERT Scraper Bowl Heaped Capacity Rated Load Struck Capacity Depth of Cut ­ max.
