Agricultural machinery parts assembly

In the maintenance of agricultural machinery,some parts are not installed due to structural restrictions,and they will be installed when they are carelessly installed,leaving the agricultural machinery with hidden troubles.Therefore,be sure to pay attention to the assembly.
1.If the cylinder head has oil holes,it must be aligned with the corresponding oil passage holes on the body and cylinder head to avoid friction caused by the oil cut-off on the cylinder head.No oil passage hole and positive and negative shape are the same,determined by the material of the cylinder head:For the aluminum alloy cylinder head,the flange side of the cylinder head should face toward the cylinder;for the cast iron cylinder cover,the flange of the cylinder head should face the cylinder head..

2.The piston and the top of the piston ring are marked with an upward arrow,etc.,and shall be installed in the direction specified by the mark;if not marked,the small eddies beside the vortex pit or pit at the top of the piston shall be toward the side of the injector.Ensure uniform gas mixing.When assembling the piston ring,the top is marked with"UP","UP",etc.,and should be facing upwards;at the top,the undistributed twisting ring should have its inner circle cut or chamfered downward;the chrome-plated ring(the shell should be bright)should be installed In the first piston ring groove,each ring opening should be staggered 120 to 180 degrees to ensure its sealing effect.

3.Connecting rod and connecting rod cover The connecting rod of the horizontal diesel engine is divided by 45 degrees,and the section should be face down to improve the stress of the connecting rod bolt.The connecting rod cover and the connecting rod are paired and processed.When assembling,the pairing marks should be on the same side to ensure that the roundness and cylindricity of the connecting rod bearing meet the specified requirements.
