Parts for your 2020 Mitsubishi Asx-Harmonic balancers

Understanding Harmonic Balancers on the 2020 Mitsubishi ASX

The 2020 Mitsubishi ASX is a popular compact SUV known for its reliability and efficient performance. When it comes to the mechanical components under the bonnet, many drivers and DIY enthusiasts might wonder about the role of a harmonic balancer in this vehicle. Is it something fitted to the ASX, and if so, why is it important? Let's dive into the details.

First up, a harmonic balancer, also known as a crankshaft damper or vibration damper, is a component attached to the end of an engine's crankshaft. Its primary purpose is to reduce torsional vibrations produced by the engine as it operates. Essentially, the crankshaft twists and vibrates slightly with each combustion cycle, and these vibrations can cause damage over time if not controlled. The harmonic balancer absorbs some of these vibrations, preventing potential wear and even failure of the crankshaft or related components.

For many vehicles, especially those with larger engines or high-performance setups, harmonic balancers are a critical part of the engine assembly. They help improve engine smoothness and longevity. However, when it comes to the 2020 Mitsubishi ASX, things are a bit different.

The 2020 Mitsubishi ASX commonly comes with a 2.0-litre naturally aspirated petrol engine or a 2.2-litre diesel four-cylinder engine, both designed with relatively straightforward engine assemblies prioritising reliability and cost-effectiveness. After reviewing technical manuals, parts databases, and service guides for the ASX, it turns out that the 2020 Mitsubishi ASX does not use a traditional harmonic balancer as found in many other engines.

Why is that? The ASX's engine crankshaft is designed in a way that does not require a separate harmonic balancer unit. Instead, Mitsubishi engineers have integrated other methods to manage crankshaft vibrations. This includes optimised crankshaft design, use of counterweights, and engineering the engine block and components to handle torsional stresses effectively without the addition of a conventional harmonic damper. Additionally, the accessory drive pulley on the ASX often doubles as a vibration damper, incorporating balance functionality within a single component rather than a separate harmonic balancer.

This design choice is partly to keep the engine lightweight and cost-effective, something that is appealing to the target market for the ASX. It also reduces the number of parts under the bonnet which may need servicing or replacement, meaning owners can enjoy a simpler maintenance routine.

So, if you own a 2020 Mitsubishi ASX or are considering one, you probably won't find a standalone harmonic balancer on your engine. Instead, the engine's vibration management is cleverly built into the crankshaft and accessory pulley system already.

That said, although the ASX does not have a traditional harmonic balancer, the components that take on similar roles - like the crankshaft pulley - still require inspection and maintenance during servicing. A worn or damaged pulley can cause issues with belt tension, accessory function, and in some cases vibrations that affect engine smoothness. Service centres often check the crankshaft pulley along with belts and other drive system parts to ensure everything runs smoothly.

For those curious about harmonic balancers in vehicles generally, here's a bit more on their importance where fitted. Harmonic balancers are vital for absorbing the twisting energy from the crankshaft, which prevents potential stress fractures or damage to the engine over time. If they fail or wear out, it can lead to engine vibrations, a rough idle, or even damage that could be costly to repair.

Replacement or maintenance of harmonic balancers usually involves checking for cracks in the rubber damper section, signs of pulley wobble, or unusual noises coming from the front of the engine. Timing belt or serpentine belt replacement intervals often coincide with harmonic balancer inspections, making it a good practice to get them both looked at simultaneously.

Luckily for 2020 Mitsubishi ASX owners, the absence of a traditional harmonic balancer means there is one less component to worry about. Just keep up with regular servicing schedules and have the drive belts and pulleys checked regularly, and the engine's vibration control system will do its job without any fuss.

If any unusual vibrations or noises do develop around the crankshaft pulley area, it's a good idea to get it diagnosed promptly. While the ASX might not have a classic harmonic balancer, problems with the pulley or accessory drive components can still affect engine performance and potentially lead to further issues if left unaddressed.

In the end, the 2020 Mitsubishi ASX blends smart engineering with practical design by effectively managing crankshaft vibrations without the need for a dedicated harmonic balancer. This approach keeps servicing straightforward and reduces potential points of failure, helping to make the ASX a dependable choice for Aussie drivers looking for a smooth and trouble-free ride.
