What is the order of car engine disassembly (parts)?

Compressed valve spring: Remove the valve adjustment gasket, remove the inlet and exhaust valves, use valve disassembly pliers to compress the valve spring, remove the lock, spring seat, valve spring and valve successively, and use sharp-nosed pliers to remove the valve rod oil seal. Notes on the disassembly order of the engine: Do not scratch the valve seat, and the valve oil seal should be replaced with a new one.

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.

The order of disassembly and installation of the engine you mentioned is a little too complicated. The order of disassembly and installation is also different according to the brand of engine. This belongs to precision machinery. If you don't know anything, don't move around. You'd better find a professional to help you disassemble the engine.

Dismantling the internal equipment! Remove the removable accessories on the engine body in turn first! Example: The gasoline pump water pump is then disassembled from the top to bottom of the engine! But the first thing you do is to finish the oil in the oil sup shell. The first is the valve chamber cover, and the second is the convex shaft, the three-cylinder head, the four-oil span, the oil pump, the five-connecting rod and the piston.

The disassembly and installation parts must be placed in order; the overall disassembly and installation process should be to remove the scattered parts first and then to the main part; prepare the space, cloth and tools before starting to disassemble and install the engine;When installing, do the other way around. Install the main part first and then install the accessory part.

How to disassemble and install car engine and gearbox

1. Disassembly speed from the gearbox Odometer flexible shaft. 3) Remove the ventilation hose from the gearbox. 4) Remove the clutch cable from the clutch separation rocker arm and gearbox.5) Disassemble the connection harness and accessories of the engine. Disassemble according to the relevant requirements of "Engine Disassembly". 6) Lift the vehicle with a lifter.

2. Disassembly of the engine should be done step by step: remove the engine from the frame, drain the water and oil in the water tank, turn off the car fuel tank switch; remove the oil pump oil pipe connector; remove the power cord and wire on the generator; remove the water tank inlet pipe, nut, connecting bolts and pins, etc.

3. Empty 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.

4. Remove the positioning screw, washer, spring, steel ball and reverse light switch.Remove the shift control device and positioning pin. Remove the oil release screw, refueling screw and speed sensor. Remove the transmission hanger. Cross, remove the transmission housing bolt in three times. Remove the sealing screw.

What are the engine disassembly steps

1. 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.

2. Automobile engine disassembly process and steps Disassembly of engine body components 1) Remove the fixed 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.

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. Engine disassembly steps: place the engine upright, 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.

Basic steps for disassembly and installation of automobile engines

1. Remove the fixing screw of the cylinder head, note that the screws should be crossed and loosened from both ends to the middle, and the screws 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. 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. 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.

4. 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.

5. 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.
