2. Remove the engine from the frame, release the water and engine oil in the water tank, and turn off the switch of the car fuel tank; remove the oil pipe connector of the oil pump; remove the power cord and remove the wire on the generator; remove the inlet pipe of the water tank and the nuts, connection bolts and pins everywhere; remove the water tank and frame; remove the hair Motivation hood, wing plate.

3. 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.

4. Remove the cylinder head fixing screw, and note that the screw should be crossed 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.

5. Engine disassembly steps: 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.

The process and steps of automobile engine disassembly

Remove the cylinder head and gasket, cylinder head bolts and screws The mother 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.

Place the engine vertically. Remove the fixing screw of the cylinder head. Note that the screws should be loosened from both ends to the middle, and the screws should be removed three times.
