Parts for your 2001 Daihatsu Gran move-Harmonic balancers

2001 Daihatsu Gran Move Harmonic Balancer

For the 2001 Daihatsu Gran Move (also known as the Pyzar in some markets), a harmonic balancer is indeed fitted. Technical references including the Daihatsu Pyzar/Gran Move workshop manual (Engine Mechanical section for HC-EJ 1.3 and HD-EP 1.6 engines) and the Daihatsu Electronic Parts Catalogue list the crankshaft pulley as a damper type with a bonded rubber isolator. That means the crank pulley doubles as a torsional damper — commonly called a harmonic balancer — to protect the crankshaft and accessory drive.

On this Gran Move, the harmonic balancer’s job is to soak up the twisting pulses that travel through the crank when each cylinder fires. By damping those vibrations, it helps the engine run smoother, reduces stress on the timing and accessory belts, and keeps the alternator and water pump happier. It also keeps the timing marks accurate for tune-ups.

They’re not typically a scheduled replacement item, but they do age. Heat, oil leaks, and time can harden or swell the rubber, and the outer ring can begin to wobble or slip. Gran Move owners and techs should give the balancer a quick look at each service — especially in Aussie and Kiwi conditions where stop–start driving and heat are common. If there’s wobble, cracking rubber, chirping from the front of the engine, belt walk, or unexplained vibrations at idle and cruise, it’s time to sort it.

• Inspection cadence: check visually at every service (around 10,000–15,000 km) and any time belts are replaced.
• Tell-tale signs: perished or oil-soaked rubber, pulley runout, misaligned belts, or slipping timing marks.
• Good practice during replacement: follow the workshop manual for locking the crank and torque specs, replace the crank bolt/washer if specified by Daihatsu, clean the snout, lightly oil as specified, and check the front main seal while you’re there.
• Complementary checks: accessory and timing belts, idlers, and any oil leaks that might attack the new damper’s rubber.
• Parts choice: stick with genuine or reputable aftermarket dampers designed for the HC-EJ/HD-EP engines — generic solid pulleys without a damper aren’t appropriate.

Expect typical replacement to take around 1–2 hours in a workshop. Parts availability is generally good through aftermarket suppliers and specialist Daihatsu networks in Australia and New Zealand.

Popular questions about 2001 Daihatsu Gran Move harmonic balancers

Does the 2001 Gran Move actually have a harmonic balancer?
Yes. The crankshaft pulley on HC-EJ (1.3) and HD-EP (1.6) engines is a damper-type pulley with a bonded rubber isolator, as shown in Daihatsu service manuals and EPC listings for the M1xx Gran Move/Pyzar series.

What are the common symptoms of a failing harmonic balancer on this model?
Look for pulley wobble, cracking or separated rubber, belt squeal, charging or cooling issues due to slip, and a new vibration through the cabin at idle or steady revs. If the timing marks seem to “move” compared with known TDC, the outer ring may be slipping.

How much does replacement usually cost in Australia or New Zealand?
Ballpark: a quality replacement damper typically sits in the $150–$400 AUD/NZD range for parts, with 1–2 hours of labour depending on access and tooling. Costs vary by brand and workshop rates, and may rise if belts or the front crank seal are done at the same time.
