Land Rover Part Number: ERR3442 - Crankshaft Damper 3.9 V8
ERR3442 is a crankshaft damper for the 3.9 V8. Fitted to the crankshaft snout, this damper uses a bonded inertia mass and an elastomeric element to absorb torsional vibration from the engine firing pulses, reducing harmonic stresses on the crankshaft, main bearings and timing drive components. It helps prevent metal fatigue at the crankshaft snout and keeps the timing assembly running with steadier rotational input; replacement is typical when the elastomer degrades, the inertia ring shows imbalance, or visible play appears at the mounting face.
Use the compatibility data below to confirm fitment against your V.I.N.
Compatibility
- Discovery 1 - 3.9 V8

Frequently Asked Questions
ERR3442 dampens torsional vibration on 3.9 V8 crankshafts by way of a bonded inertia ring and elastomeric element, reducing peak loads on the crankshaft, main bearings and timing drive. It helps prevent fatigue at the crankshaft snout and keeps timing components receiving steadier rotational input. Typical failure modes are elastomer degradation, inertia ring imbalance or play at the mounting face, which indicate replacement is required.
