Parts for your 2013 Ford Ranger-Harmonic balancers

2013 Ford Ranger Harmonic Balancer

For the 2013 Ford Ranger (PX) sold in Australia and New Zealand, a harmonic balancer is absolutely fitted and relevant. Ford’s Workshop Manual for the PX Ranger (Section 303-01 for the 2.2L and 3.2L Duratorq TDCi engines) details removal and installation of the crankshaft vibration damper. Ford’s Electronic Parts Catalogue also lists the crankshaft damper under the core part base number 6B319, and major aftermarket catalogues for the PX Ranger carry complete balancer assemblies. That makes it clear the Ranger uses a bonded-rubber torsional vibration damper on the front of the crank.

Put simply, the harmonic balancer (crank pulley with an internal damper) absorbs twist and shock in the crankshaft. Diesel Rangers—especially the 3.2 five‑cylinder—produce plenty of low‑rpm torque and firing pulses. The balancer’s job is to smooth that out, protect the crank from fatigue, and keep the accessory drive stable so the belt, alternator and A/C don’t cop a hiding.

As part of regular servicing, it’s smart to eyeball the balancer for perished rubber, radial cracks, or any wobble while idling. Oil contamination from a weepy front main seal can soften the rubber layer, so check for that under the bonnet too. If the rubber is separating or the outer ring has crept, replacement is the go—these units aren’t rebuild items.

• Common warning signs: noticeable vibration at idle or 1,500–2,000 rpm, belt chirp, accessory belt walk, outer ring wobble, or a sudden change in charging/A/C performance.
• Inspection cadence: every service, from about 150,000–200,000 km, be extra vigilant, especially on vehicles that tow or work hard.

When replacing, use an OE or high‑quality equivalent balancer and a new crankshaft bolt (it’s torque‑to‑yield). Follow the Ford WSM procedure: lock the crank with the proper holding tool, clean the snout, align the keyway/dowel if applicable, and torque/angle the new bolt exactly as specified. It’s also a good time to fit a fresh drive belt, check the overrunning alternator pulley and tensioner, and inspect the front seal. Done right, the engine will run smoother, accessories will be happier, and the crank will thank you over the long haul.

Popular questions about 2013 Ford Ranger harmonic balancers

What are the symptoms of a failing harmonic balancer on a 2013 Ranger?
Drivers often report a shake at idle or cruising rpm, belt squeal, or spotting the pulley “wobbling” with the bonnet up. The rubber layer may look cracked or oily, and belts can start tracking off-line or wearing quickly. Address it early to avoid collateral damage to the belt drive.

Do harmonic balancers have a replacement interval?
There’s no fixed kilometre interval from Ford. Treat it as condition‑based: inspect each service and be particularly cautious from around 150,000–200,000 km. Heavy towing, off‑road dust, and oil leaks can shorten life. Replace at the first sign of rubber degradation, run‑out, or noise.

Can the balancer be repaired, or should it be replaced?
They’re not serviceable. The rubber bond is critical and can’t be reliably rebuilt in the vehicle. Replace the complete assembly with a quality unit, fit a new crank bolt, and follow the workshop manual torque‑and‑angle procedure with the correct holding tool.
