Components of the Car Manual Transmission System and Their Functions

Here are the components of the manual transmission system in cars, among others:

1. Transmission Input Shaft

In fact, the transmission input shaft is a gear or shaft that works simultaneously with the clutch. This component functions as the gear turner in the gearbox. 

2. Transmission Gears

Another component is the transmission gears. The transmission gears are used to convert the input from the power generated by the engine into torque input.

Later, the change from the transmission gears will be adjusted according to what the vehicle needs. 

3. Shift Fork

Used to shift gears from their shaft, the shift fork has an important function. By shifting the gear from the shaft, the gear can be more easily installed or reversed. 

4. Transmission Lever

Another name for the transmission lever is the gear shift lever. The function of this manual transmission component is to control the driver to shift the transmission gears according to the driver's condition. Usually, this component is located not far from the driver. 

5. Linkage Lever

The function of the linkage lever is to connect the gear shift lever and the shift fork.

7. Output Shaft

The shaft that functions to transfer torque from the transmission system to the final gear is called the output shaft. This component can also be used for the gear shift mount in the car. 

8. Transmission Case

Another component you should know is the transmission case. The transmission case is used for the bearing mount of the transmission and its shafts. Not only that, the transmission case is also used as a container that holds transmission oil. 

With this component, the movement and shifting of each component in the car's transmission system will run smoothly. 

9. Bearings

The function of the bearings is to reduce friction caused by the surfaces of the components rotating in the transmission system. 

10. Reverse Gear

As a converter of the output shaft rotation, the reverse gear is certainly very much needed. With this component, your car can move backward when shifting the gear lever to reverse gear. 

11. Counter Gear

There is also a component called the counter gear. This component is used as a torque generator from the input gear to the speed gear.

13. Hub Sleeve

The function of the hub sleeve component is to lock the gear adjustment. With this component, the output shaft will rotate and stop. 

It turns out that there are so many manual transmission components. Because of the numerous components, each component can certainly wear out and experience damage. To prevent this, you should regularly take your car to the workshop. 

One recommended workshop is the official workshop or Daihatsu dealer. The official Daihatsu workshop will provide the best service and offers so that all the spare parts and devices of your car are well maintained.
