Parts for your 2014 Mitsubishi Asx-Harmonic balancers

2014 Mitsubishi ASX harmonic balancers — what they do and when to replace them

Technical sources confirm the 2014 Mitsubishi ASX is fitted with a harmonic balancer (also called a crankshaft pulley with torsional damper). Mitsubishi’s workshop literature for ASX/RVR/Outlander Sport models describes a crankshaft pulley incorporating a bonded rubber damper, and the Mitsubishi ASA electronic parts catalogue lists a damped crank pulley for 4B11 petrol and 2.2 Di‑D diesel variants. Major aftermarket catalogues used in Australia and New Zealand (Dayco and Gates) also list a torsional vibration damper for 2010–2015 ASX engines, which corroborates OE fitment.

On a 2014 ASX, the harmonic balancer’s job is to soak up crankshaft twist and vibration each time a cylinder fires. It keeps the engine smooth, protects the crank and bearings, and helps the accessory belt run true so the alternator, A/C compressor and other driven bits aren’t shaken about. When the rubber bonding layer hardens, cracks, or separates with age and kilometres, the pulley can wobble, belts can squeal, and cabin buzz can creep in.

There’s no fixed replacement interval for the balancer, it’s a condition-based item. As part of regular servicing, a tech should pop the bonnet and check:

• Perished, cracked or “oozing” rubber between the inner hub and outer ring
• Visible pulley run‑out or wobble with the engine idling
• Chirps/squeals from the front of the engine or a flickering charge light
• Accessory belt wear that returns quickly after a new belt is fitted

If any of that shows up, replacement is the go. Best practice on the ASX is to use a quality OE or premium aftermarket damper, fit a fresh accessory belt at the same time, and follow the Mitsubishi workshop procedure for removal/installation. That includes using the correct holding tool and a torque/angle spec for the crank bolt as per the manual, plus thread locker or a new bolt if specified. Avoid levering against the timing cover or prying on the rubber element—damage there shortens the new part’s life.

Driving long with a failing balancer risks losing the belt and copping charging issues or overheating (depending on engine variant and belt routing). Most workshops in AU/NZ will sort the job in about 1–2 hours. It’s a small bit of preventive care that keeps the ASX feeling tidy on the open road and around town.

Popular questions about 2014 Mitsubishi ASX harmonic balancers

Does a 2014 ASX actually have a harmonic balancer?
Yes. Mitsubishi’s service manual describes a crankshaft pulley with an integrated torsional damper on 4B11 petrol and diesel variants, and both Mitsubishi ASA parts listings and local Dayco/Gates catalogues show a replacement harmonic balancer for 2010–2015 ASX models. It’s standard kit, not an add‑on.

What are the common signs the balancer is failing?
Look for a wobbly crank pulley at idle, perished or split rubber between pulley sections, fresh belts that start squeaking again, or new vibrations through the cabin. Some drivers also notice intermittent battery/charge warnings because the alternator belt can slip when the damper separates.

How often should it be replaced and what does it cost?
There’s no scheduled interval—inspect at each service and replace on condition. In Australia and New Zealand, quality balancers typically sit in the few‑hundred‑dollar range for parts, with 1–2 hours’ labour. Many workshops will recommend a new accessory belt and fresh bolt (if specified by Mitsubishi) during the job.
