* Other auxiliary belt-driven components
Correct pulley condition is important for smooth belt operation and reliable accessory drive.

Replacement may be required due to:
* Cracked or damaged pulley
* Excessive vibration
* Pulley wobble
* Damaged belt grooves
* Unusual rattling or knocking noise
* Auxiliary belt running incorrectly
* Corrosion or physical damage
* Damage during engine repair
* Worn centre mounting area
Important Diagnostic Information
If there is noise or vibration from the auxiliary belt system, also inspect:
* Auxiliary drive belt
* Belt tensioner
* Idler pulleys
* Alternator pulley
* Power steering pump pulley
* Air-conditioning compressor
* Crankshaft mounting bolt
* Crankshaft nose / mounting surface
A belt-drive noise does not always mean the crankshaft pulley itself is faulty.

Correct crankshaft pulley installation is important to prevent belt misalignment or engine damage.
Important Compatibility Note
Please compare your original pulley carefully before ordering.
Check:
* Part number – 03G105243
* Engine code
* Pulley diameter
* Number of belt grooves
* Centre mounting design
* Offset / depth
