- make sure all parts are clean and free of foreign bodies before installing them;
- always lubricate any rotating or sliding parts. This should be done before assembling, not after the parts are already installed, otherwise the oil will not get to all the necessary places. It is especially important to generously lubricate the pistons, piston rings and cylinder walls with engine oil before assembly;
- thoroughly clean all parts of the cylinder block if the engine has been completely disassembled;
- when partially disassembling, make sure that no foreign bodies get into the disassembled engine or into its cavities. Plug all openings with clean rags to avoid this;
- blow out the oil passages with compressed air. If this is not possible, then clean the oil channels and holes with a wooden stick, but in no case do this with metal objects;
- always replace O-rings and gaskets with new ones;
- the table with data for adjustment and control shows the wear limits of most moving parts. If there are doubts about the wear of any part or the wear limit will soon be reached, then it is better to immediately replace such a part in order to avoid re-disassembling the engine after a short time. Please note that the adjustment and control data for different engine models are different.
