Bad Effects When CVT Pulley Wears Out

Pulley CVT Tergerus

Symptoms when the CVT pulley is worn will feel like there are unstable vehicle movements and high vibrations. This certainly triggers extra work from other components and it cannot be denied that it will damage other components in the automatic transmission system using CVT.

Automatic cars do require extra maintenance, especially in the transmission area. There are many components that play an important role in the operation of this claimed smoother automatic system, one of which is the CVT pulley. 

So what happens if the pulley on the CVT is already worn? In this discussion, we will provide a brief overview of the negative effects that may occur from the damage to the CVT pulley.

Negative Effects When the CVT Pulley is Worn

Continuous Variable Transmission, or more commonly known as CVT, is a system or mechanical series as a drive installed in automatic transmission vehicles. In this system, there are important components, one of which is the pulley. A worn CVT pulley will have negative impacts that you need to be aware of.

Here we provide an overview of the negative effects that may occur when there is wear on the CVT pulley and it is left unattended.

1. Occurrence of movement jumps when the vehicle is moving slowly

One of the effects that occur when the CVT pulley is worn is when you drive slowly or start the vehicle, you will feel unstable movement jumps. This is due to the imprecision between the pulley and the belt. If left unchecked, it will certainly damage other components.

2. Presence of very high vibrations

The working system in CVT mechanics is very complex, so it requires components that are precisely related. The wear on the pulley will cause significant vibrations that can be felt from inside the vehicle cabin, especially when the vehicle starts to move. This is certainly very uncomfortable for driving.

3. Acceleration becomes slower, heavier, and rough

The presence of an incorrect angle on the CVT pulley will result in slow, heavy, and rough acceleration. This is caused by the rotation of the belt and pulley being imprecise. The rotation of the belt and pulley is not smooth, which will certainly damage other components if not replaced immediately.

4. Engine rotation is unstable

With a worn CVT pulley, it will certainly affect the engine rotation of your vehicle. The engine rotation becomes unstable and feels heavy, because the CVT working system is not optimal. This certainly makes driving uncomfortable, especially for long journeys.

5. A lot of engine power is wasted

A worn and imprecise CVT pulley makes the engine performance not fully transmitted and much is wasted. In automatic transmission vehicles, this pulley serves as a link between the engine and the drive wheels. If this CVT series does not work well, then engine power will be wasted.

6. Fuel consumption becomes wasteful

An imperfect CVT working system results in wasted fuel because the power generated by the engine is not transmitted well. Fuel consumption becomes too high because a worn pulley certainly requires high RPM to operate the vehicle.

The presence of a worn CVT pulley component certainly makes the vehicle uncomfortable to use. We, Daihatsu Indonesia, provide various CVT spare parts and other components according to your needs.
