    One of the oil angle adjustment methods to loosen the bleed screw on the pump pump body, pump the pump oil with the hand pump, drain the air in the low pressure oil pump, and tighten the bleed screw.

    Remove the fuel tank from the first cylinder high pressure tubing, will accelerate the pedal to the end.

    Find the engine a cylinder compression top dead center position. Press the crankshaft on the flywheel to align the * 0 * scale line on the flywheel, the first cylinder plunger spring of the Please login to see links and more information. is in a compressed state (the intake and exhaust valves of the engine cylinder should be closed) The

    Press the crankshaft in the direction of rotation of the engine by about 50 degrees, and then slowly turn the crankshaft in the direction of rotation and observe whether the oil level of the first cylinder high pressure tubing joint is fluctuating.

    If the pointer on the flywheel shell has not been aligned with the angle specified in the advance angle of the flywheel on the front of the flywheel, the oil cylinder forehead is too large and the Please login to see links and more information.coupling Take the two screws on the drive plate and continue to pry the crankshaft so that the pointer on the flywheel housing is aligned with the fuel feed advance angle specified on the flywheel and then tighten the two screws on the drive plate.

    If the pointer on the flywheel shell. When the angle of advancement of the oil supply advance angle on the flywheel is specified, the oil level of the first cylinder high pressure tubing joint has not fluctuated 'indicates that the fuel supply advance angle is too small and the two screws on the drive pump coupling plate should be released, Turn the fuel pump camshaft slowly and evenly in the direction of rotation of the Please login to see links and more information.. Stop the rotation when the oil level of the first cylinder high pressure tubing has just fluctuated, then tighten the two screws on the drive plate.

    Method 2 Loosen the bleed screw on the pump pump body, pump the pump oil with the hand pump, drain the air in the low pressure oil pump, and tighten the bleed screw.

    Remove the fuel tank from the first cylinder high pressure tubing, will accelerate the pedal to the end.

    Press the crankshaft in the direction of rotation of the crankshaft, and observe the oil level of the first cylinder high pressure tubing joint. When the fuel level overflows the nozzle, turn the crankshaft by 1/4 turn to 1/2 turns.

    According to the direction of rotation of the crankshaft slowly pry the crankshaft, while paying close attention to the first high-pressure tubing fuel pump fuel tank surface, when the liquid surface has just fluctuated immediately stop the crankshaft, this time, the flywheel on the pointer on the flywheel On the scale value, that is, the current fuel supply advance angle of the degree. Such as the angle does not match the specified angle, you can loosen the coupling on the active plate of the two screws, the fuel pump camshaft through the required increase or decrease the angle (Yellow River JN2182 tractor equivalent to the crank angle 3 * Yanan SX2150 tractor each grid is equivalent to crank angle 8 *). When adjusting, reduce the fuel supply advance angle, the camshaft rotates in the direction of rotation; increase the fuel supply advance angle, the cam shaft rotates in the opposite direction. Finally, tighten the two screws on the drive plate of the coupling and repeat the check once until the specified angle is reached. For example, when checking the SX2150 engine fuel supply advance angle, the flywheel housing pointer is aimed at the flywheel scale value of 11 ° (Yanan SX2150 tractor feed angle of 19 °), you can loosen the two screws , The fuel pump can be turned a small cell counterclockwise.

    Method 3 Loosen the bleed screw on the pump pump body, pump the pump oil with the hand pump, drain the gas in the low pressure oil pump, and tighten the bleed screw.

    Remove the fuel tank from the first cylinder high pressure tubing, will accelerate the pedal to the end.

    Loosen the coupling drive two screws, remove the front valve door cover.

    Pry the engine crankshaft to make a cylinder in the compression stroke, and according to the provisions of the oil to find the location of the advance angle.

    Clockwise rotation of the Fuel injection pump camshaft, while observing the first high-pressure fuel pipe fuel pump nozzle fuel tank surface fluctuations occur when the rotation.

    Check the fuel supply advance angle and the provisions of the difference between the little, do not have to release the coupling rotation of the fuel pump camshaft, and as long as the fuel pump four mounting screws slightly loose, so that the fuel pump body for a small turn Adjustment, its direction of rotation should be the opposite of the second method, adjust the screw after the tightening.

    Generally the first cylinder oil supply advance angle adjustment is correct, the other cylinder fuel supply advance angle do not have to check and adjust separately.

    Fasten the two screws on the coupling disc.
