Disassembly and installation steps of automobile engine

1. Disassembly and steps of automobile engine disassembly of engine body components 1) Remove the fixing screw of the cylinder head, and pay attention to the screws should be from both ends Cross and loosen in the middle, and remove the screw in 3 times.2) Lift the cylinder head. Remove the cylinder pad and pay attention to the installation direction of the cylinder pad.

2. Place the engine upright and remove the intake and exhaust manifolds and cylinder head outlet pipes. Remove the cylinder head cover, remove the rocker arm shaft assembly on the front and rear cylinder head; remove the crankshaft ventilation pipe, and remove the boom chamber cover; remove the putter.

3. Disassembly steps: To remove the external components of the aircraft, 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.

4. The disassembly method of the engine includes the following steps: remove the fixing screw of the cylinder head, loosen it from both ends to the middle, and remove it three times; lift the cylinder head, remove the cylinder pad, release the oil release screw of the engine oil span, and loosen the engine oil span.

Steps for disassembly and installation of the car engine?

1. Remove the fixing screw of the cylinder head. Note that the screw should be crossed and loosened from both ends to the middle, and the screw should be removed three times. 2) Lift the cylinder head. Remove the cylinder pad and pay attention to the installation direction of the cylinder pad. Loosen the oil release screw of the oil span shell to release the oil in the oil span shell.

2. Place the engine upright and remove the intake and exhaust manifolds and cylinder head outlet pipes. Remove the cylinder head cover, remove the rocker arm shaft assembly on the front and rear cylinder head; remove the crankshaft ventilation pipe, and remove the boom chamber cover; remove the putter.

3. The disassembly and installation method of the engine includes the following steps: remove the fixing screw of the cylinder head, loosen it from both ends to the middle, and remove it three times;Lift the cylinder head, remove the cylinder pad, release the oil release screw of the engine oil sup, and release the engine oil sup.

4. The engine disassembly steps are carried out in the order of machine, assembly, parts, assembly and parts. Pay attention to proofreading the assembly mark when disassembling to ensure that it can be reassembled as it is. When disassembling various threaded connectors, it should be disassembled in a professional symmetrical order to ensure the complete disassembly of the threaded connectors.

5. Remove the front mask and baffle of the engine. First, loosen the six nuts fixing the front mask cover and the two fixing bolts on the left and right of the radiator, and remove the front bumper, as shown in Figure 3. Loosen the four hexagonal fixing nuts in front of the front mask and remove the front mask. Loosen the two screws fixing the condenser on the longitudinal beam.

6. Remove it in the gearbox bodyDismount assembly: First remove the clutch cover and the flywheel connection bolt, and then move the detacher 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.

What is the process of disassembling and installing the engine?

Fix the bolt under the shock absorber after removing it. Remove the two M10×55 engine suspension bracket bolts, pull the engine back together with the rear wheel and remove it. Remove the ignition coil from the engine suspension bracket, remove the engine mounting bolt M10×185 nut, remove the engine suspension assembly, and remove the engine assembly.

First, remove the battery ground wire, drain the coolant, remove the mask and baffle, remove the pipelines such as oil 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.

Turn the crankshaft to put the engine's 4-cylinder piston at the lower stop. Remove the fastening nuts of the connecting rod of the 4-cylinder respectively, remove the connecting rod bearing cover, pay attention to the connecting rod pairing mark, and put it in order.

Engine disassembly steps: place the engine upright and remove the intake and exhaust manifolds and cylinder head outlet pipes. Remove the cylinder head cover, remove the rocker arm shaft assembly on the front and rear cylinder head; remove the crankshaft ventilation pipe, and remove the boom chamber cover; remove the putter.

Disassemble the engine crankshaft flywheel group, loosen the flywheel to fasten the screw, disassemble the flywheel, the flywheel is relatively heavy, pay attention to safety when disassembly.Remove the front and rear sealing flanges and oil seals of the crankshaft.

What is the disassembly process of the engine?

The process of removing from the engine rack: (1) Empty the water and oil in the tank, turn off the car fuel tank switch, and remove the oil pump 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.

First, remove the fuel supply system, ignition system, cooling system and other system-related parts from the engine, so as to disassemble the cylinder block crankcase group. Remove the cylinder head cover, remove the camshaft, etc. to facilitate the removal of the cylinder head.

The engine disassembly process of mechanical assembly is roughly as follows: place the engine upright, remove the inlet and exhaust manifolds and the cylinder head outlet pipes. Remove the fixing screw of the cylinder head, note that the screw should be crossed and loosened from both ends to the middle, and the screw should be removed three times. Lift the cylinder head, remove the cylinder cushion, and pay attention to the installation direction of the cylinder cushion.

The process of removing from the engine rack: drain the water and oil in the tank, turn off the switch of the car fuel tank, and remove the oil pipe connector of the oil pump;Remove the power cord and the wire on the generator. Remove the inlet pipe of the water tank and the nuts everywhere. Connect bolts and pins, etc.
