John Deere Construction Lubrication System

John Deere Construction Lubrication System

John Deere lubrication system is designed to reduce friction between the mating parts of the John Deere engine. In addition to performing the main function, the lubrication system provides cooling of engine parts, removal of coke and wear products, and protection of parts of the John Deere engine against corrosion. 

John Deere lubrication system partsThe engine lubrication system includes a crankcase with an oil sump, an oil pump, an oil filter, an oil cooler, which are interconnected by lines and ducts. 

The engine oil sump is designed for storing oil. The oil level in the pallet is monitored with a feeler gauge, as well as with the oil level and temperature sensor. 

John Deere Oil Pump is designed to pump oil into the system. The oil pump can be driven from the engine crankshaft, camshaft or additional drive shaft. The greatest application on engines was found John Deere gear oil pumps. 

The John Deere oil filter serves to clean oil from wear and sludge products. The oil is cleaned with a John Deere filter element, which is replaced with an oil change. 

The John Deere oil cooler is used to cool the engine oil. Cooling of the oil in the radiator is carried out by the flow of liquid from the cooling system.

John Deere Construction oil pumps
The John Deere Construction oil pump is designed to create pressure in the lubrication system, and thus lubricate the moving parts of the internal combustion engine. The John Deere Construction oil pump is driven by a John Deere Construction crankshaft or John Deere Construction camshaft by means of a drive shaft. By the nature of the control oil pumps are divided into uncontrolled and adjustable. Unregulated pumps maintain a constant pressure in the lubrication system by means of a pressure reducing valve. In controlled pumps, the constant pressure is maintained by changing the pump capacity. Depending on the design, oil pumps are distinguished for gear and rotary pumps. John Deere Construction gear oil pump is a two-pinion gear - the driving and slave, housed in the body. Oil enters the pump through the suction channel, is captured by gears and injected into the system through the discharge channel. The output of the gear pump is proportional to the speed of the crankshaft.  
John Deere Construction oil filters
The John Deere Construction oil filter is a very important link in the John Deere Construction lubrication system. During the operation of the engine, the oil flushes away the carbon deposits and engine wear products. The absence of a John Deere Construction oil filter or its clogging will result in all these solid particles again falling between the parts of the engine, speeding up their wear and tear. Approaching thereby costly repairs. The replacement of the John Deere Construction oil filter is made together with the replacement of oil.

John Deere Construction feed pumps
The John Deere Construction feed pump is a low-pressure fuel pump. The main objective of this device is the function of supplying fuel to a high-pressure fuel pump - the John Deere Construction injection pump. Typically, a feed pump is installed on the injection pump housing or in the immediate vicinity of injection pump. Both pumps are connected by means of fuel pipes, through which fuel is supplied from one pump to another. The John Deere Construction feed pump (low pressure fuel pump) is needed to pass fuel through the John Deere Construction filters and then inject the fuel into the high-pressure fuel pump - the John Deere Construction injection pump. It is worth noting that the feed pump pumps a little more fuel than the engine needs to operate. This swap "with a margin" allows you to maintain the optimum pressure in the fuel system, avoiding increasing loads.

John Deere Construction fuel filters
John Deere Construction fuel filters serve a vital function for modern vehicles that are sensitive to the quality of motor fuel. Unfiltered fuel may contain several types of contaminants, for example, pieces of paint and dirt that could get into the fuel tank during refueling, or rust caused by moisture in steel tanks. If these substances are not removed before the fuel enters the system, they will lead to rapid wear and damage to the John Deere Construction fuel pump and John Deere Construction injectors, due to the destructive effects of particles on important components used in modern injection systems. John Deere Construction fuel filters also increase the engine's power, since the less pollutants present in the fuel, the more efficient the combustion. Some John Deere Construction filters, especially on diesel engines, have the shape of a cup for collecting water at the bottom. The water can then be drained by opening the valve at the bottom of the bowl. A lot of John Deere  
John Deere Construction fuel pumps
In direct injection engines as well as diesel engines, the John Deere Construction electric fuel pump is used in the low pressure circuit for pre-supplying fuel to the high-pressure pump - John Deere Construction injection pump. The electric John Deere Construction fuel pump creates a fuel pressure in the limit of 0.3-0.4 MPa (in engines with direct injection - up to 0.7 MPa). The use of mechanical pumps in John Deere Construction fuel injection systems is not possible due to low fuel delivery pressure. By design, the following types of electric fuel pumps are distinguished: roller, gear and centrifugal. In the John Deere Construction roller pump, the fuel is sucked and injected by rotating the rotor and moving the rollers therein. As the space between the roller and the rotor increases, a vacuum is created, and the fuel fills this space. When the space is full, the fuel supply is cut off. As the rotor rotates, space decreases, the discharge port opens and the fuel leaves the pum 
John Deere Construction injection pumps
John Deere Construction injection pump is one of the main components of the diesel engine injection system. The John Deere Construction pump, as a rule, performs two main functions: injecting a certain amount of fuel under pressure and regulation of the required timing of the injection. With the advent of battery injection systems, the injection timing control function is placed on electronically controlled John Deere Construction injectors. The basis of the John Deere Construction injection fuel pump is a plunger pair that combines a piston (plunger) and a cylinder (bushing) of a small size. John Deere Construction plunger pair is made of high-quality steel with high precision. Between the plunger and the bushing, a minimum gap is provided - precision mating. Depending on the design, the following types of high-pressure John Deere Construction fuel pumps (John Deere Construction injection pump) are distinguished: in-line, distribution and main. In a series pump, injection of fue
