Disassembly and installation of automobile engines Step

After removing all the bolts and nuts, knock on the circumference of the cylinder head with a wooden hammer to lift them up, and then use a disassembly tool to put them into the valve duct holes at both ends of the cylinder head or remove them smoothly by hand.Note that it is not allowed to insert the cylinder head to avoid damaging the cylinder pad.

Steps for disassembly and installation of automobile engine valve group Disassembly of automobile engine valve group (1) Remove the valve adjustment gasket. (2) Remove the inlet and exhaust doors. Use valve disassembly pliers to compress the valve spring, and remove the lock, spring seat, valve spring and valve successively. (3) Use sharp-nosed pliers to remove the valve lever oil seal.

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.

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 air.Manifold, remove the cylinder hood, and then remove the gasoline pumps on both sides, so that the external components of the engine are basically disassembled.

Remot the front mask and baffle of the engine. First, loosen the six nuts that fix 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.

Remantle the disener assembly in the gearbox body: first remove the clutch cover and the flywheel connection bolt, and then move the disener 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.

Who can send a video of disassembling the engine on a car

At the auto show, the engineer once said, A single cylinder can be opened and closed in 14 milliseconds, completing the transition from three cylinders to two cylinders. Therefore, I am still very interested in this engine. Some time ago, I came to the engine factory of Chongqing Ford Motor Company for the first time to disassemble this engine.Through disassembly, I found a lot of interesting points.

Put the engine sideways and check whether there are marks on the clutch cover and flywheel. If there is no mark, it should be made up. Then turn the crankshaft flywheel, remove the eight clutch fixing bolts symmetrically and evenly around the clutch cover, and remove the clutch assembly.

The cylinder block is an important part of the engine, which is equivalent to the brain of the engine. It organizes and installs various parts of the engine and has the effect of regulating the temperature. The power of the engine is transmitted by the sealing function of the cylinder block and the cylinder head.

And we are also surprised to find that Japan, which is also the top of the world's automobile industry, never seems to mention this technology. In many disassembly videos, we can still see that Japanese manufacturers are using traditional connecting rod parts.

Basic steps for disassembly and installation of automobile engine

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.

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.

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

First, unscrew the external screw, and then remove the transmission shell to observe the installation position of the transmission and the connection with the engine.

Unplug the dual-temperature switch of the radiator and the connection plug of the electric fan. Loosen the engine hatch lock cable clip and pull out the cable from the top of the radiator. Remove the front mask and baffle of the engine. First, loosen the six nuts that fix 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.
