	Remove
	The individual components of a shift rocker arm (3) ↓ Valve lever (4) Roller lever (5) Coupling pin (7) Thrust pin (8) are machined together and must therefore not be mixed up. If the individual components of one shift rocker arm have been mixed up with those of another shift rocker arm, this can result in operational problems of the shift rocker levers.
