During the maintenance process of diesel forklift truck, the engine, as an important component of internal combustion forklift truck, is responsible for the power source of forklift truck operation. Electric forklifts rely on electric motors for power. Of course, mechanical operation is bound to bring wear and tear, so maintenance is often a thing.

How to disassemble and wash the engine
First, remove the engine from the forklift truck first, must be carried out under the condition of complete engine cooling, otherwise it will cause the deformation of some parts.
1. Water is released from the engine cooling system, and oil and hydraulic oil are released from the engine and hydraulic transmission.
2. Remove the safety shed and seat, remove the radiator cover, and remove the exhaust pipe muffler.
3. Take off the pedal and remove the radiator, exhaust pipe and its auxiliary devices.
4, remove the engine and hydraulic transmission and other system coupling parts (hose, conduit, etc.).
5. Decompose the connection between the engine and the main drive (universal joint, etc.).
6, the engine is hung on the lifting equipment, and the screw bolt is connected with the frame.
7. Lift the engine with lifting equipment and place the engine on the bench.

Check for wear
1, first look at the color and quality of the oil, the surface is whether there is iron filings, look at the viscosity of the oil. For example, there is a lot of iron filings in the oil, indicating that the crankshaft tile or connecting rod tile should be worn, and even the crankshaft is worn. If the machine is very viscous, the oil has not been changed for a long time.
2. Observe the connecting rod tile and crankshaft tile when disconnecting the crankshaft of the connecting rod piston. If it is found that the whole connecting rod can not be used anymore, if the crankshaft is not very serious, it can be used again after grinding shaft processing.
3. Observe the wear of the cylinder liner, and pay attention to not hitting the engine body when disassembling the cylinder liner to prevent damage.

At this point, is the main steps of engine maintenance. Although it seems simple, it takes a long time of experience to fix an engine. Any small details of the error will lead to the engine can not operate normally, so the maintenance of the engine this thing of course needs experienced personnel to operate, must not blindly start.
