Parts for your 2022 Mitsubishi Eclipse cross-Harmonic balancers

2022 Mitsubishi Eclipse Cross harmonic balancer

Yes, the 2022 Mitsubishi Eclipse Cross is fitted with a harmonic balancer (also called a crankshaft damper or torsional vibration damper). This is confirmed in Mitsubishi Motors’ service information for the 4B40 (1.5L turbo) and 4B12 (2.4 PHEV) engines, where the “crankshaft pulley” is specified as a bonded rubber damper assembly and removal/installation procedures are provided. The Mitsubishi ASA parts catalogue also lists a crankshaft pulley with integrated damper for Eclipse Cross models in this year range, and major aftermarket catalogues used by workshops in Australia and New Zealand (e.g., Dayco and Gates) publish part listings for the Eclipse Cross harmonic balancer.

On the 2022 Eclipse Cross, the harmonic balancer’s job is to soak up twisting vibrations created each time a cylinder fires. It’s the front pulley on the crank, with a rubber layer sandwiched between the hub and the outer ring. That rubber is the hero—by damping torsional spikes it keeps the engine smooth, helps protect the timing chain and bearings, and keeps accessory drive components happier and quieter.

While there’s no scheduled replacement interval in the Eclipse Cross service program, the balancer should be checked during routine servicing—especially as the kilometres rack up or if there’s been oil contamination around the front crank seal. Because both the 1.5T and the 2.4 PHEV use timing chains rather than belts, the balancer isn’t changed on a “belt service,” but it’s still smart to inspect it whenever the drive belt is off.

What to look and listen for:

• Visible cracking, swelling, or separation of the rubber layer
• Pulley wobble at idle or a chirp/rumble that tracks engine speed
• New vibrations through the cabin, especially around 1,500–2,500 rpm
• Accessory belt walking off-line or premature belt wear

If any of that shows up, park the car and get it checked. Driving with a failing damper can damage the crankshaft nose and front seal, and it can flick the serpentine belt. A proper replacement involves locking the crank, removing the single-use centre bolt, fitting the new damper square to the keyway, and torquing the new bolt to spec using the OEM procedure. Given the tight centre-bolt torque and the need for correct alignment, it’s a workshop job unless one is very well equipped.

Good practice for Eclipse Cross owners in Aus/NZ: inspect the drive belt every 15,000 km or 12 months, keep oil leaks sorted so they don’t soak the damper rubber, and use quality parts that match the OE mass and durometer so the engine stays silky and reliable.

Popular questions

Does the 2022 Mitsubishi Eclipse Cross actually have a harmonic balancer?

It does. Mitsubishi’s service manual for the 4B40 and 4B12 engines specifies a crankshaft pulley with an integrated rubber damper, and the Mitsubishi ASA catalogue lists a damper-type pulley for this model year. Aftermarket Australian and New Zealand catalogues also carry direct-fit torsional vibration dampers for the Eclipse Cross.

When should the harmonic balancer be replaced on a 2022 Eclipse Cross?

There’s no fixed interval. Replace it if the rubber shows cracking or separation, if the pulley wobbles, there’s new vibration, or the belt tracks poorly. Have it inspected at each service, or any time the front drive belt is removed. Don’t keep driving if symptoms appear—damage can escalate quickly.

How much does replacement typically cost in Australia or New Zealand?

Costs vary with engine variant and part choice. As a rough guide, allow for around 1–2 hours of labour plus the damper and a new centre bolt, many workshops also recommend a new accessory belt. Total fitted pricing commonly lands in the mid-hundreds, but ask your local workshop for a firm quote based on your VIN.
