ERC5349 is a crankshaft or auxiliary drive pulley designed for Land Rover Defender models fitted with 2.25 and 2.5 petrol engines, on vehicles without air conditioning or power steering. The pulley transfers rotational force from the crankshaft to drive ancillary components such as the alternator and water pump via the drive belt. A worn, cracked, or misaligned pulley can cause belt slippage, belt wear, and overheating or charging system failure if left unaddressed. Key Features Specified for non-air conditioning, non-power steering drivebelt configurations on 2.25 and 2.5 petrol engines Direct OEM-equivalent replacement - no modification required for fitment Designed to maintain correct belt alignment and tension across the ancillary drive system When replacing this pulley, inspect the drive belt, belt tensioner, and water pump for wear as a matter of course Vehicle Fitment Fits Land Rover Defender (1986–2006) with 2.25 Petrol and 2.5 Petrol engines, on vehicles without air conditioning and without power steering.
