D8T Track-Type Tractor Strength from the past. Power for the future. TM The D8T combines power and efficiency with advanced technology for outstanding production at a lower cost-per-yard. C15 Engine with ACERT® Technology ACERT Technology works at the point of combustion to optimize engine performance and provide low exhaust emissions. Matched with the torque divider and power shift transmission, it provides years of dependable and efficient service. [. . . ] Abutment-style caps securely attach rollers and idlers to the bogies. Roller frames are tubular to resist bending and twisting, with added reinforcement where operating loads are highest. · · · Roller frames attach to tractor by a pivot shaft and pinned equalizer bar. Large pivot shaft bushings operate in an oil reservoir. A low friction, no maintenance bushing is used in the saddle connection. Aligned to use more of the available wear material, running the track to the outside of the rollers in forward and to the inside in reverse. Positive Pin Retention (PPR) Sealed and Lubricated Track. Designed for high-impact and high load applications. The PPR exclusive Caterpillar design locks the link to the pin. Track shoes come in a variety of sizes and styles to best match the working conditions. · 10 Structure Engineered to provide durability and the solid support necessary for maximum production and service life in the most demanding work. Tag-Link. The Tag-Link brings the blade closer to the machine for more precise dozing and load control. The Tag-Link design provides solid lateral stability and better cylinder positions for constant break out force, independent of blade height. Mainframe Strength. The D8T mainframe is built to absorb high impact shock loads and twisting forces. Full box section, designed to keep components rigidly aligned. Adds strength to the main case, equalizer bar saddle, front cross member and tag-link trunnion. Continuous rolled sections, with no machining or welding, to provide superior mainframe durability. Main Case. Elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants. The D8T pivot shaft runs through the mainframe and connects to the roller frames, allowing independent oscillation. The full-length pivot shaft distributes impact loads throughout the case, reducing the bending stress on the case. The equalizer bar features limited slip seals and an oil-lubricated joint for better oil flow. Large forged pads reduce wear on the mainframe and extend sealed joint life. 11 Integrated Electronic Solutions Caterpillar technology offers customers new opportunities for efficiency and profitability. AccuGrade Ready Option. The factory ready option machine makes system installation and setup quick and easy, and optimizes performance and reliability.
