Gear shift diagram t 130

The T-170 bulldozer is a tracked special equipment that is used in construction and agriculture, on soils with low bearing capacity (swampy, snow, frozen soil).

The first T-170 tractor rolled off the assembly line in the spring of 1988 and immediately established itself only on the positive side, and a little later the T-170 bulldozer became the most popular special equipment. The technical characteristics of the T-170 are at a very high level, and it is thanks to such technical indicators that it gained its popularity.

Bulldozer T-170

The T-170 is a slightly improved modification of the T-130 tractor. The T-170 is equipped with a more powerful engine of the same series with a torque reserve of 25%, and it is also capable of running on various types of fuel: diesel, kerosene, gas condensate. A bulldozer-ripper or a pipe layer is manufactured on the basis of a tractor. At the end buyer's request, the tractor can be equipped with: a pre-heater, various types of starting equipment and other options; all this is agreed upon when purchasing the equipment.

Construction of the T-170 bulldozer

Structure of the bulldozer T-170

Engine

The T-170 bulldozer is equipped with the D-160.11 engine and its modification D-180.111-1Yu, which have a service life of 8,000 hours before overhaul. With the update, the engine became more powerful, reaching 180 hp, and the torque also increased. A turbocharged engine is able to “digest” different types of fuel: diesel fuel, kerosene, gas condensate. Starting is carried out from a P-23U carburetor starting engine or an electric starter. The installed optional pre-heater PZD-30 allows the bulldozer to be used in arctic conditions with temperatures down to -50?C.

Transmission

The transmission uses a four-shaft constant mesh gearbox. As standard, it is equipped with 8 forward and 4 reverse gears. For installation on some modifications of the bulldozer, the first two gears of the normal and accelerated ranges can be blocked, which turns the box into a 6-speed one.

Hydraulic system

The hydraulic system uses a gear hydraulic pump NSh-100, mounted on the engine. Purification of the working fluid is ensured by Regotmas filter elements. Degree of purification - particles up to 25 microns in size. The configuration of the entire hydraulic system depends on the attachment used and may vary.

Electrical equipment

The on-board voltage of the bulldozer is 24 V. Depending on the modification of the bulldozer, 2 batteries are installed: 6ST-182EMS in the case of using an electric starter engine starting system or 6ST-75TM if a starting motor is used. The 1 kW generator is equipped with an electronic voltage regulation system.
