1、 Check the wear of forklift engine parts

1. First look at the color and quality of forklift oil, whether there are iron filings on the surface, and see the viscosity of the oil. For example, there are a lot of iron filings in the engine oil, which means that the crankshaft bearing or connecting rod bearing should be worn, and even the crankshaft should be worn. If the machine is very viscous, it means that the oil has not been changed for a long time.

2. When disassembling the crankshaft of connecting rod piston, observe the condition of connecting rod bush and crankshaft bush. If it is found that the whole connecting rod can not be reused after being grinded, if the crankshaft is not seriously grinded, it can be reused after being grinded.

3. Observe the wear condition of the cylinder liner, and pay attention not to hit the engine block when disassembling the cylinder liner to prevent damage.

3、 After inspection and replacement, reassemble the forklift engine parts (the installation sequence is generally from the inside to the outside, from the bottom to the top, from the back to the front, and from the left to the right, that is, the reverse order of disassembly).

1. Crankshaft, crankshaft bush surface, connecting rod, piston, piston and camshaft shall be smeared with engine oil during installation, and collision is not allowed.

2. When installing the camshaft and high pressure fuel injection pump gear, pay attention to the alignment of the first cylinder mark on the gear.

3. When installing the piston ring, a special worker should be used to install it from the third ring to the first ring. The piston ring is used as a whole set and cannot be damaged at will.

4. The vertical and horizontal openings should not be staggered.

5. When installing the cylinder liner, grease the O-ring instead of knocking the cylinder liner directly with iron.

6. When installing the piston and connecting rod assembly, use special tools and install it according to the original direction of the piston. It is not allowed to knock the piston directly with iron and apply oil on the connecting rod bush (contact surface with crankshaft).

7. Apply oil on both sides of the cylinder gasket.

8. When installing the cylinder head screws, use a kg wrench to tighten them in two to three times from the middle to the four sides. The force of the first screw is 250 to 300 n, and each screw has the same force. When tightening the crankshaft and connecting rod bush, tighten them in two to three times from the middle to both ends.
