Tractor t-74-user guide/instruction on repair, maintenance and operation.
Tractor t-74 refers to the type of caterpillar tractors, heavy duty and is intended primarily for work in agriculture with mounted and trailed machines and guns at higher speeds.
The guide describes the design of the Caterpillar tractor t-74 and its mechanisms; provides instructions on care mechanisms during the operation, rules of preventive maintenance, lubrication and rules etc. Guide is for tractor drivers, foremen tractor crews, mechanics and other persons associated with the operation.
Reliable and long work of a tractor depends to a large extent on the timely and proper care. When operating a tractor, you need the following:
1. before starting the engine make sure that you have oil in the crankcase and water in the radiator.
2. After running the tractor replaced the oil in the engine, transmission and other mechanisms and wash oil filters; tighten the cylinder head mounting nuts and adjust the valve clearances; check and tighten the fastening of other nodes.
3. working on a tractor, follow the indications for appliances. Maintain the temperature of the water in the cooling system and oil within 80-95° c by using the radiator shutters. Running the engine with the air intake air cleaner links is strictly prohibited.
4. apply the fuel and oil only those marks which are indicated in this manual.
5. fill the fuel tank with clean diesel fuel, otstaivavšeesâ at least 48 hours.
6. During the cold time of the year, at a temperature below 0 ° C, to avoid the unfreezing of the engine if the tractor is stopped for a long time, it is necessary to drain the water from the cooling system, leaving the heat sink and the drain pipe open on the crankcase. Every 480 hr. The work shall be removed from the engine, the injectors shall be checked and, if necessary, adjusted to the injection pressure and the quality of the dust. Every 960 hours. the fuel pump to be checked for performance and the same performance as the feed. In order to ensure the long-term operation of the gearbox, the main transmission and the on-board transmission and the prevention of premature failure, it is necessary to carry out the following: Work to change the oil in the gearbox, the main and the onboard gear from the mandatory flushing of the diesel fuel. During the transition to winter operation, the gearbox, the main and the on-board transmissions (A K-10, A-15). To avoid the introduction of dust and dirt into a gear box and the main gear, do not allow tractors with loose bolts of the attachment of the back bridge cover and the fastening of the gear box to the rear bridge, as well as other connections of the transmission. In the event of a leak in the seal of the primary shaft, the replacement of the HIPCs is replaced by a new one, which is attached to each tractor. Every 960 hours. and the replacement of bearings with a check of the secondary shaft clearance in bearings 66409D. The axial displacement of the secondary shaft shall not exceed 0.3 mm. In order to eliminate the high dynamic loads for the transmission of the transmission when the tractor is moving from the field, it is necessary to allow the tractor to be applied at low engine speed (the middle position of the fuel lever). In the case of a D-45 raincoat type tractor, it is also necessary to start at low engine speeds, with a smooth insertion of the main clutch. After moving the tractor with a ford and also daily when working at the bottom of the tractor with the submersion of a tractor, it is necessary to check the level of lubrication in the final gears and in case of increasing the level by getting water and dirt to replace the lubricant with the washing of the crankcase. It is necessary to check the condition of the compaction of the on-board transmission and correct the detected faults. To switch the pump on and off only if the engine is not running. During the operation of the tractor it is necessary to monitor the functioning of the spring rubber buffers of the engine, especially the rear. We strongly recommend that you adhere strictly to the guidelines.
