When the diesel engine (including the new machine and the overhaul machine) is put into use for the first time, the following preparations must be made before starting the diesel engine:
1.Check the integrity of the machine, the tightness of the bolts of each component and make sure no looseness of each pipe joint.
2. For new machines, the oil should be removed and wiped clean.
3. For the new machine, the diesel crankshaft should be manually rotated several times.
4. Add enough fuel to the fuel tank.
5. Add a qualified brand of engine oil to the diesel engine.
6. Check the battery electrolyte gravity, which should be in the range of 1. 29g / cm 3 .
7. Check whether the high pressure oil pump rack is flexible, whether the throttle lever is flexible.
8. Fill the fixed fueling point with oil according to daily maintenance.
9. Deflation of the fuel line: When the new diesel engine or the overhauled diesel engine is used for the first time, the fuel supply system must be deflated,

The bearings in your engine are relatively small but they play a vital role in keeping everything running smoothly. Worn bearings will seriously affect the operation of your engine, leading to over-heating, excessive noise and wear on other components and, in extreme cases, to the failure of the engine unit itself.
To prevent this, you need to follow the relevant maintenance instructions and, when necessary, replace bearings before they become an issue.
Your engine’s bearings protect the crankshaft and engine itself from damage, as well as keeping the engine lubricated.
Bearings are found in many of the machines we use every day. Without bearings, we would be constantly replacing parts that wear out from friction, so it is important to check them in accordance with the schedules supplied when you bought your engine.
Lambert bearings are either tangless or tanged, as dictated by the engine model and unit you are using. The tang – sometimes called a lug – helps to position the bea
