Rocker Arm, engine timing - RA90 MOTIVE

The rocker arm (sometimes the name rocker is found) - transfers forces from the cam of the shaft to the valve stem with the camshaft fixed in the upper position. Due to this process, the mass of the timing belt is reduced and friction is reduced.

The functionality of the engine timing rocker arm

The MOTIVE brand Rocker Arm, engine timing are in the mechanism of every modern vehicle; they automatically change the length by an amount due to the movement of parts under the action of the spring mechanism. The rocker arm consists of four parts:

1. The body is a rocker arm or a cylindrical pusher.
2. Plunger pair - solid steel cylinder and bushing.
3. A spring is a location in a plunger pair between its components.
4. Check valve - metal ball.

Gas distribution mechanisms of a modern type are equipped with reliable rockers, with a service life equal to the period of operation of the engine. The engine rocker arm can jam or be damaged due to the use of contaminated and low-quality oils. The indicator of a device malfunction is a knock that is uncharacteristic for engine operation.
