I'd be wondering about the fuel system, but not rich or lean, but the timing. If it is working all it should be doing is shortening the time till engine is up to operating temp and setting the minimum while running. First agree that removing t-stat is not good.
The D6 ? with 185 hp of gross power and an operating weight of 18 tons is in the middle of Caterpillar's track-type tractors.This was the first D6 with Caterpillar's elevated drive sprocket undercarriage, known as the CAT Hi-Drive system.
The Hi-Drive D6H was introduced in 1986 along with 3 other H-Series track-type tractors.They were replaced after 60,000 had been built in 1959 with the D6B.
This makes it ideal for working on very steep slopes, in forests, and for backfilling pipelines safely without risking damage to the pipe.Ī low ground pressure version is also available with extra wide tracks to provide low ground pressure which allows working in muddy areas without sinking.Ĭaterpillar first introduced the D6 in 1941 with the 4R & 5R series to replace the Caterpillar RD6. The vehicle is powerful, yet small and light, weighing 16 to 20 tons (18 to 23 short tons) depending on configuration (recent models). The D6 is primarily used to move material short distances or through challenging terrain. The Caterpillar D6 track-type tractor is a medium bulldozer manufactured by Caterpillar Inc.
