Parts for your 2022 Toyota Land cruiser-Harmonic balancers

2022 Toyota Land Cruiser harmonic balancer: what it does and how to look after it

Based on Toyota’s workshop literature and parts catalogues for the 2022 Land Cruiser 300 Series (including the V35A‑FTS 3.5‑litre twin‑turbo petrol and F33A‑FTV 3.3‑litre twin‑turbo diesel), the crankshaft pulley is an integrated torsional damper—commonly called the harmonic balancer. So yes, the 2022 Land Cruiser does use a harmonic balancer, and it’s a key bit of kit for engine longevity and smoothness.

The harmonic balancer’s job is to soak up crankshaft twist and vibration created every time a cylinder fires. By damping those torsional pulses, it protects the crank, timing chains, oil pump drive and accessory belt system, while also trimming noise and harshness in the cabin. On modern V6s with strong torque low in the rev range—like the LC300’s petrol and diesel—the damper does plenty of heavy lifting during towing, sand work and long highway stints.

There’s no fixed replacement interval in Toyota schedules, the balancer is “inspect and replace if required”. A quick visual and functional check during belt inspections is smart, especially after 100,000–150,000 kilometres or if the vehicle sees a lot of heat, mud, oil contamination or corrugations.

• Look for perished or cracked rubber between the hub and outer ring
• Watch for pulley wobble at idle, chirps/squeals, or fresh belt dust
• Check for oil leaks that can swell and degrade the damper elastomer
• Note new vibrations through the seat or steering at specific revs

If any of the above pops up, replacement is the go. Use an OE‑quality damper and a new crank bolt. This is a precision, high‑torque, torque‑angle job: a holding fixture and a balancer puller/installer are typically required. Don’t lever against the timing cover or shock the crank with an impact. Clean the crank snout and mating surfaces to factory guidance and line up any keyway or indexing as specified. While you’re there, inspect the front crank seal and the serpentine belt/tensioner, then verify belt tracking after first start.

Post‑fit, let it warm up, listen for any belt noise and check for runout. If the Land Cruiser spends time off‑road, rinse the front drive area after muddy work and keep oil leaks sorted—both help the balancer live a long, quiet life.

Popular questions

Do all 2022 Land Cruiser engines run a harmonic balancer?
Yes. Both the 3.5‑litre twin‑turbo petrol (V35A‑FTS) and the 3.3‑litre twin‑turbo diesel (F33A‑FTV) use a crankshaft pulley with an integrated torsional damper. It’s essential for controlling crankshaft vibration and protecting the accessory drive.

How long should the harmonic balancer last on an LC300?
Often the life of the engine, provided it isn’t oil‑soaked or cooked by sustained heat. In Aussie and Kiwi conditions, regular inspections are wise after 100,000–150,000 kilometres, especially if towing, touring or off‑roading is a big part of life.

Is it safe to drive with a failing harmonic balancer?
Not recommended. A slipping or delaminating damper can throw the belt, take out charging and cooling, and in the worst case damage the crank. If there’s wobble, cracking or sudden new vibration, park it and arrange a repair.
