How about the Deer 950 high-pressure common rail engine

Deer 950 reinforced front axle, stability Higher than Tianto 100, the whole machine transmission system is strengthened, the operation reliability is high, the final transmission gear and transmission shaft are strengthened, the final transmission housing is strengthened, and it is equipped with a high-pressure common rail engine controlled by wood electrically, with superior power performance, and 4 hydraulic outputs as standard, which can be equipped with a variety of agricultural machinery.

First of all, John Deer engines have been fully verified and have the characteristics of high quality and low failure rate. They are very reliable and basically do not need to be repaired during the use period, so there is no need to add urea. Secondly, the John Deer electronically controlled high-pressure common rail engine can meet the national four emission standards without adding urea.

So that the pressure of the high-pressure oil pipe has nothing to do with the speed of the engine, it can greatly reduce the change of diesel fuel supply pressure with the engine speed, thus reducing the defects of traditional diesel engines. ECU controls the injection volume of the fuel injector. The size of the injection volume depends on the pressure of the fuel rail (public oil supply pipe) and the opening time of the solenoid valve.

Good. The durability and power performance of the Deer 4045 engine are fully guaranteed, and the quality is very good. John Deere PowerTech electronically controlled high-voltage common rail supercharged 4045 engine is powerful, fuel-efficient, reliable and easy to maintain.

Powerful. The horsepower of the John Deer 4045 is 141 horsepower, so the engine is very powerful. John Deer 4045 is equipped with excellent performance, high quality and reliability, and adopts advanced electronically controlled high-voltage common rail technology.

How about 20 John Deer 5b704

John Deer 5b704 is a bridge. 5b704, 5b is the fifth model b, and 704 refers to the engine horsepower of 70 and the number of variable speed groups of 4 groups. John Deere 5b704 is a model of tractor. Bridge and small bridge are a structure of tractors. The weight of bridge tractors is heavier than that of small bridge tractors.

Hello, as far as I know, the John Deer 5B704 you mentioned. It belongs to Tianjin, which is absolutely true.

Excellent performance. Power system: This tractor adopts an in-line four-cylinder four-stroke water-cooled direct injection combustion chamber engine, which has a high calibration power and fuel consumption rate.

20丨John Deer six-cylinder Oriental Red factory in 5 years What model is equipped with the original engine of the second largest pump in China

Solution: It is recommended to clean the engine carbon frequently. Empty air filter: If it is not replaced in time, it will cause insufficient air intake and lower engine idle speed, resulting in engine shaking.Solution: Replace the empty air filter.

How is the performance of Dongfanghong Guosan 6-cylinder 13oo horsepower tractor? Dongfanghong is an advanced domestic enterprise, and the quality is still passed! In terms of engine, it's okay, that is, foreign-funded Deer.

No. The third engine of Dongfang Hongguo is a high-pressure common rail engine, which cannot be pumped. Motivation has no effect. The engine is the power source of the car. Most of the car engines are thermal power devices, referred to as thermal engines. The thermal machine converts the thermal energy generated by fuel combustion into mechanical energy by using the state change of the work quality.

Different performance. At present, the 5E, 6B, 7M and 8R launched by John Deer in China are all very technical. John Deer's high-horsepower tractors are basically power shifters.

Oil route problems: Check the oil route system, including oil pumps, oil routes, oil nozzles and other components, to ensure that there is no blockage or damage. Gas path problem: Check the gas path system, including gas pump, gas path, air nozzle and other components, to ensure that there is no air leakage or blockage.

John Deer engine small throttle abnormal sound, large throttle normal

1. The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston is not accurate due to the depth and width of the main bearing oil tank; the oil pressure is low and moist Poor slippery.

2. If the abnormal sound of the transmission is obvious, it is still recommended to send it to a professional repair shop to check the defective parts and then replace them. There is an abnormal sound in the door. Symptom description: There is always some abnormal noise in a certain part of the car body when stepping on the accelerator or brake.The noise is not loud, and it does not affect normal driving, but people are always a little worried about where there is something wrong.

3. This kind of noise is usually relatively loud, and the parts are relatively worn, so it should be repaired in time. Generally, when starting, the oil temperature of the car has not reached the normal value, resulting in the viscosity that is not suitable for the normal working value of the hydraulic support rod. The sealing of the hydraulic support rod is reduced, and it will make a sound. When the new car is driving, there will be problems with the accelerator pedal. Don't panic.

What accessories need to be replaced for the John Deer 904 to 1404 engine

Engine overhaul mainly includes the replacement of valves, pistons, cylinder liners, boring cylinders, grinding shafts, etc. According to the standards of general 4S stores, 4 sets of accessories need to be replaced., that is, piston, piston ring, valve, valve oil seal, valve duct, crankshaft bushing, connecting rod bushing, timing belt, tensioning wheel.

Engine overhaul mainly includes the replacement of valves, pistons, cylinder liners, grinding shafts, etc. According to the standard, 4 sets need to be replaced, namely piston, piston ring, valve, valve oil seal, valve duct, crankshaft pad, connecting rod pad, timing belt and tensioner.

Sometimes it is necessary to replace external accessories, such as clutch pieces. In short, all uncertain parts should be replaced to repair the engine and ensure engine performance. The mechanical part generally includes a set of intake and exhaust valves, a set of piston rings, a set of cylinder liners with four thrust plates and two pistons.

The best repair is to replace the engine cylinder block, piston and piston ring;When there are conditions, you can bore the strained cylinder liner and replace the larger piston and ring. Other accessories, such as cylinder bed, crankshaft oil seal, etc., should also be replaced.
