Engine installation, what to pay attention to when disassembly

1. When disassembling and installing the engine, it should be placed smoothly to prevent dumping and injuring people. Pay attention to the safety of electricity and oil, and do not smoke in the disassembly and installation site.

2. Remove the oil pan shell and do not twist it. The Wuling B series engine uses an iron oil bottom shell, which is not easy to disassemble because there is glue on it when disassembling. 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.

3. 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 in 3 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.

4. Do not warp and deform when disassembling the oil pan. The Wuling B series engine adopts an iron oil sup shell. Because there is glue on it when disassembly, it is not easy to disassemble. Do not warp and deform at high temperatures, otherwise oil will leak after installation. The best way: use special tools when disassembling. Bolts should be disassembled in order.
