3. The engine power is insufficient and the exhaust emits black smoke.

① The air filter is blocked. ② The exhaust turbocharger is carbonized or damaged. ③ The electronic control system is faulty (the monitor has information display). ④ The fuel delivery pump, injection pump or injector is faulty. ⑤ The injection timing is not accurate. ⑥ Piston, piston ring and cylinder liner are worn. ⑦ The valve is not tightly closed or has a fault, and the valve clearance is inaccurate.

4. The engine has a large exhaust volume.

The piston, piston ring and cylinder liner are worn.

5. The engine burns oil and the oil loss is large.

① Too much oil. ② The piston, piston ring and cylinder liner are worn. ③ The floating oil seal of the exhaust gas turbocharger is damaged. ④ The valve guide is broken.

6. There is oil in the water tank.

① The oil cooler core is broken. ② The water pump water seal is damaged and the drain hole is blocked. ③ The cylinder gasket is damaged.

7. There is coolant in the oil bottom.

① The oil cooler core is broken. ② The cylinder gasket is damaged. ③ The cylinder head or cylinder block has cracks.

8. Yog 'bosimi past.

① Insufficient oil. ② There is diesel and coolant in the oil. ③ The oil filter is blocked. ④ The oil pump suction pipe is leaking. ⑤ The oil safety valve (bypass valve) is stuck in the overflow state or the spring is broken. ⑥ The oil pump is worn. ⑦ The gap between the crankshaft or camshaft and the bearing is too large.

IX. Suv harorati juda yuqori.

① The coolant capacity is small. ② The thermostat is damaged. ③ The belt is loose and the fan speed is low. ④ The water pump is damaged. ⑤ The engine is overloaded. ⑥ The water tank is blocked inside or outside. ⑦ Mechanical failure inside the engine.

10. The generator is not charging.

① The battery is damaged. ② The charging circuit or the grounding circuit is faulty. ③ The engine brush is worn. ④ The regulator or the rectifier diode is damaged. ⑤ The rotor (excitation coil) is damaged.

11. The hydraulic pipe is shaking and the hydraulic pump is noisy.

① There is air in the hydraulic pump. ② The inclined plate or plunger shoe in the hydraulic pump is worn.

12. Walking deviation.

① The track tension is improperly adjusted. ② The corresponding travel motor leaks internally, or the reducer is damaged. ③ The hydraulic pump leaks internally, and the flow rate is small. ④ The travel control pilot circuit is faulty, or the travel main circuit is faulty. ⑤ The oil seal in the center slew comment is damaged, and oil is leaking.

13. Sekin sayohat tezligi.

① The pilot control oil circuit or the main oil circuit component is faulty. ② The pilot pump or hydraulic pump is faulty. ③ The oil seal in the center slew is damaged, and oil is leaking.

14. Walking climbing is weak, and the digging force is insufficient.

① The safety valve of the main circuit and the pilot circuit is faulty, and the pressure is low. ② The corresponding safety relief valve, balancing valve, buffer valve, etc. are faulty. ③ The hydraulic pump, pilot pump and control valve leak internally.

15. The electrical function of a certain circuit is not available.

① The corresponding fuse is damaged. ② This circuit component is damaged or the wire is faulty.
