Coupling information:

The function of the coupling is not only to transmit power, but also to compensate for the deviation of the coaxiality between the two shafts during installation and to adjust the fuel supply timing of the fuel injection pump by using a small amount of relative angular displacement between the two shafts.
Driven by the fuel injection pump, it is driven by the timing gear at the front end of the crankshaft through the intermediate transmission gear to drive the fuel injection pump timing gear. This group of gears are engraved with timing engagement marks, which must be assembled according to the marks to ensure the fuel supply timing of the fuel injection pump.
The timing gear output shaft of the fuel injection pump and the camshaft of the fuel injection pump are connected by a coupling. Some fuel injection pumps directly use the arc groove on the casing to adjust the timing of fuel supply by rotating the pump body relative to the camshaft of the fuel injection pump, omitting the coupling.
