Drive Belt Idler Assembly for the front-end auxiliary drive system. The idler runs on the outer face of the auxiliary (serpentine) drive belt, guiding its path and supporting belt tension around the crankshaft, alternator and ancillary pulleys.

Used on the 2.4L and 2.2L TDCi turbo diesel engines. The pulley turns on a sealed bearing and bolts to the engine front cover; a worn or seized bearing typically shows as belt noise, vibration or misalignment.

Frequently asked questions

What does the drive belt idler assembly do?

The drive belt idler assembly guides the auxiliary serpentine belt and supports its running path around the crankshaft, alternator and ancillary pulleys. It runs on the outer face of the belt, turns on a sealed bearing, and bolts to the engine front cover on the Puma TDCi diesel.

Which Defender engines does this idler assembly fit?

It fits the Defender 2007-2016 Puma with the 2.4L TDCi 140PS, VIN 7A000001 to BA999999, and the 2.2L TDCi 122PS from VIN CA000001, with or without air conditioning. Confirm your engine and VIN, as the belt layout changed across the Puma run.

How is an idler different from the tensioner pulley?

The idler is a free-running pulley that just guides the belt, while the tensioner pulley sits on a sprung arm that sets and holds belt tension. They're separate parts on the Puma drive system, so check which one is worn before ordering.

What are the signs the idler bearing is failing?

A worn or seized idler bearing typically shows as belt noise, a rumble or squeal, vibration, or belt misalignment. Left unchecked, a seizing pulley can throw or shred the auxiliary belt, so renew it once you hear bearing noise from the front of the engine.
