Replace the throttle oil pump oil seal.
First, overhaul those projects?
1, if it is a timing chain, it is necessary to replace the timing chain and tensioner, except for machining, boring cylinder lower sleeve, grinding shaft and cold pressing conduit. Also need to replace overhaul package, crankshaft front oil seal, crankshaft rear oil seal, oil pump, research valve, etc. Sometimes it is necessary to replace external accessories, such as clutch plates. In short, it is necessary to put all the uncertain accessories in.
2. The general mechanical part mainly includes a set of valve intake and exhaust, a set of piston rings, a set of cylinder liners with four thrust plates (if it is a four-cylinder engine) and four pistons;
3. The general cooling system mainly includes water pump (water pump blade corrosion or water seal leakage), engine water pipes, large circulating iron pipes, small circulating rubber hoses, throttle pipes (aging and expansion must be replaced), thermostats, etc.
The fuel part generally includes the upper and lower oil rings of the fuel injector and the gasoline filter; Ignition part: replace the high-voltage line if it rises or leaks, and hit the ignition piston; Upper and lower oil rings of nozzle and gasoline filter;
4. Ignition part: replace the high-voltage line if it rises or leaks, and hit the ignition piston;
5. Generally, the air intake part mainly includes the air filter;
6. Other auxiliary materials generally include antifreeze, engine oil, engine oil grille, cleaning agent, engine metal cleaning agent or universal water;
7. Generally, the parts to be inspected mainly include whether the cylinder head is corroded or uneven, crankshaft, camshaft, timing belt tensioner, timing belt adjusting wheel, timing belt, engine outer belt and adjusting wheel, rocker arm or rocker shaft. If it is a hydraulic tappet, more hydraulic tappets are detected.
8. Cooling system: water pump (water pump blade corrosion or water seal leakage), engine water pipe, large circulating iron water pipe, small circulating rubber hose, throttle water pipe (aging and expansion must be replaced);
9. Fuel part: The overhaul package includes cylinder gasket, various oil seals, valve cover gasket, valve oil seal and gasket.
Engine overhaul projects generally include engine overhaul, out-of-plane machining of cylinder head, boring cylinder, clean water tank, valve grinding, cylinder liner insertion, piston pressing, oil circuit cleaning, motor maintenance and generator maintenance.
Second, overhaul the engine parts that need to be replaced
1, one set of valve oil bag, one set of valve intake and exhaust, one set of plug ring, one set of cylinder liner four rows of push pieces, four large and small tiles and four plugs.
2. The cooling system generally includes a water pump (the water pump blades are corroded or the water seal shows no signs of water seepage).
3. Engine water pipes, large circulating iron pipes, small circulating rubber hoses and bone valve water pipes (must be replaced, and cannot be aged and shrunk);
4. The fuel part generally includes the upper and lower oil rings of the fuel injector and gasoline filter;
5. The ignition part generally includes whether the high-voltage line can be replaced without shrinkage or leakage. Spark plugs and air intake parts usually include air filters.
6. Other auxiliary materials: antifreeze and engine oil; Whether the cylinder head is corroded or uneven, crankshaft, camshaft, anti-timing belt tensioner, anti-timing belt zeroing wheel, anti-timing belt, external engine belt and zeroing wheel, rocker arm or rocker arm shaft. If it is a hydraulic tappet, the overhaul package includes cylinder gasket and various oil seals, valve cover gasket, valve oil seal and so on.
