(If it expands, it needs to be replaced), thermostat, etc. ;

The fuel part generally includes the upper and lower oil. injector rings, fuel filter; the ignition part: if the ligne high voltage is bloated or leaking, replace it and the fire piston; the upper and lower oil rings of the fuel injection nozzle, fuel filter;

< p>4. Ignition Part: Replace the high voltage line if it is swollen or leaking and the piston is on fire;

5. The air intake part usually includes the air filters; >6. Other auxiliary materials generally include antifreeze, engine oil, engine oil filter, detergent, engine metal cleaner or all-purpose water

7. Components to be inspected generally include if the cylinder head is corroded; or uneven, crankshaft, camshaft, timing belt tensioner pulley, timing belt adjustment pulley, timing belt, external engine belt and adjustment pulley, rocker arm or rocker arm shaft, if it is 'a hydraulic lifter, please check the hydraulic lifter

8. System partth cooling: water pump (pump blades are corroded or water seal is leaking), engine upper and lower water pipes, large iron circulation pipes, small circulation pipe , throttle water pipe (needs replacement if old and swollen);

9. Fuel part: The overhaul kit includes cylinder gaskets and various oil seals, valve chamber cover gaskets, valve oil seals, etc. Gaskets and other things;

Engine overhaul projects usually include engine overhaul, cylinder head plane machining, cylinder boring, water tank cleaning, grinding of the valve, cylinder liner insertion, piston pressing, oil circuit cleaning, engine maintenance, generator set maintenance, etc.

2. Parts that must be replaced during engine overhaul
