Engine disassembly process

1. The process of valve disassembly The power source of the engine is nothing more than oil and gas. The function of the gas distribution mechanism is to open and close the intake and exhaust valves regularly according to the requirements of the working cycle and ignition order carried out in each cylinder of the engine, so that the fresh filling can be discharged in time even if the fresh filling enters the cylinder.

2. Disassembly steps: To remove the external components of the fuselage, first remove the external parts as required, and remove the motor, generator and other components. Then remove the intake and exhaust manifold, remove the cylinder cover, and then remove the gasoline pumps on both sides, so that the external components of the engine are basically dismantled.

3. Remove the battery grounding wire to avoid accidental damage to the electrical equipment.Adjust the empty switch to the "warm air" position to ensure that the coolant can be completely discharged. Open the radiator cover and the coolant bucket lid, and remove the large circulation interface hose of the water pump. Unplug the dual-temperature switch of the radiator and the connection plug of the electric fan.

4. Remove the clutch assembly in the gearbox body: first remove the clutch cover and the flywheel connection bolt, and then move the clutch up and down from the flywheel. III) Disassembly and installation of the engine 1) Remove the 13 fixing screw of the cylinder head, note that the screw should be rotated from both ends to the middle, and remove the screw in 3 times. 2) Lift the cylinder head.

Steps and precautions for disassembling the engine assembly from the car

Draining The water and oil in the water tank, turn off the car fuel tank switch, and remove the oil pump and oil pipe connector. ( 2) Remove the power cords and wires on the generator. Remove the inlet pipes of the water tank and the nuts everywhere. Connect bolts and pins, etc. Remove the water tank and frame. ( 3) Remove the hood and fender.

The specific disassembly steps are as follows: Method 1: Unplug the battery wiring when the ignition switch is turned off. Take out the battery. Pay attention to pull it out first and then take it off. Unstighten the fastening bolt of the battery bracket and remove the battery bracket.Place a collection plate under the engine. Unscrew the lid of the coolant storage tank.

Remove the cylinder head and gasket, and the bolts and nuts of the cylinder head should be disassembled in the order specified by the original car. Note: If there is no regulation, it should be disassembled evenly from both ends to the middle.

Remoll the oil pan and do not twist it. The Wuling B series engine uses an iron oil bottom shell, because there is glue on it when disassembly, so it is not easy to disassemble. Do not warp and deform at high temperature, otherwise oil will leak after installation. The best way: use special tools when disassembling. The bolts should be removed in order.

Remove the cylinder head fixing screw, and note that the screw should be crossed and loosened from both ends to the middle. 2) Remove the cylinder cushion and pay attention to the installation direction of the cylinder cushion. 3) Flip the engine and remove the oil span fixing screw (note that the screw should also be loosened from both ends to the middle).4) Remove the oil span and oil spat.

The engine assembly replacement method

Generally, the original number is mainly due to the lack of a qualification certificate for the engine or the tedious procedures to avoid change, but this is not allowed. If it is found during the inspection, the vehicle inspection will not be possible; after replacement It should be checked whether the engine harness and pipeline are messy, and it can be done according to the running standards of the new car when running in.

First, use a Phillips screwdriver to remove the self-tapping screws on the left and right sides of the leading front bar, then use the snap screwdriver to remove the snap, and finally extend the snap to the fixed position and break it open. Disassemble the air pipe: Use the snap starter to warp the two snaps up and take down the air pipe.

The specific disassembly steps are as follows: Method 1: Unplug the battery wiring when the ignition switch is turned off.Take out the battery. Pay attention to pull it out first and then take it off. Unstighten the fastening bolt of the battery bracket and remove the battery bracket. Place a collection plate under the engine. Unscrew the lid of the coolant storage tank.

The disassembly and installation order of the engine assembly is as follows. 1 Use the main support frame to support the car on the flat ground. 2 Turn the main switch to the "OFF" position. 3 Remove the outer cover of the car. 4 Dray the engine oil. 5 Remove the negative wire of the battery first, and then remove the positive wire. 6 Remove the carburetor and automatically start the thickening valve wire.

The method can only be changed after applying. When replacing the engine of the car, it shall apply for change registration to the vehicle management office of the place of registration. After the replacement, the engine number shall be reported to the vehicle management office. Changes and changes to the engine are relatively large modifications and must be applied for.

What are the steps for disassembly and installation of Jetta engine?

1. Stop the vehicle first, pull the handbrake, and disconnect the negative pole of the battery. Then, open the engine cover and clean up the dust and oil stains on the engine surface. Next, the risk of overheating the engine should be ruled out, and the disassembly operation should be carried out after it cools down. In addition, prepare the necessary tools, such as wrenches, screwdrivers and car jacks.

2. Remove the cylinder head cover and the camshaft. If you are a manner, you should master the timing position of the timing wheel or timing belt, so as to proofread the timing position during installation. Remove the oil cover. Remove the connecting rod screw. Take out the connecting rod together with the piston.

3. Hold the engine with a jack. Open the hood and remove the air filter cover and pipe. Put the base of the air filterSeat removal, a 10 and 12 sleeve, removal of the middle suspension frame, three positions of nuts and a bolt. By adjusting the height of the jack, the suspension frame is easy to remove. All 4 screws are 14 sleeves.

4. First, remove the battery ground wire, drain the coolant, remove the mask and baffle, remove the oil pipe and other pipes, and remove the flywheel cover. Put it back in the opposite direction. The specific steps are as follows: remove the battery ground wire to avoid accidental damage to the electrical equipment. Adjust the empty switch to the "warm air" position to ensure that the coolant can be completely discharged.
