Product Description

Auto Engine Parts Crankshaft Timing Pulley OE 11237548003 for BMW

The Crankshaft Timing Pulley (OE Number: 11237548003) is a critical engine timing system component exclusively engineered for multiple BMW models. Mounted on the front end of the crankshaft, it works with the timing belt/chain and camshaft pulleys to synchronize the rotation of the crankshaft (drives pistons) and camshafts (controls valve opening/closing). This synchronization is vital for maintaining the engine’s optimal combustion timing and preventing catastrophic damage (e.g., valve-piston collision).

This OE-grade pulley is constructed from high-strength nodular cast iron (GG40) or forged steel—materials chosen for exceptional torsional rigidity (resists twisting under engine torque), wear resistance, and heat tolerance (withstands under-hood temperatures up to 180°C). Unlike generic alternatives, its tooth profile (for timing belt/chain engagement), outer diameter, and crankshaft mounting hole are precision-machined to match BMW’s timing system standards. This eliminates tooth misalignment (causing timing slippage) and ensures consistent belt/chain tension, avoiding rough idling, reduced power, or engine failure. The surface also features an anti-corrosion coating (e.g., zinc plating) to resist rust from oil and moisture, ensuring long-term durability.

Core Functions

Synchronize crankshaft and camshaft rotation: The pulley’s precisely machined teeth engage with the timing belt/chain, transferring rotational force from the crankshaft to camshafts at a 2:1 speed ratio (critical for 4-stroke engines). This ensures valves open/close exactly when piston movement requires, preventing valve-piston contact (a major cause of engine damage) and maintaining efficient combustion.
Maintain stable timing system operation: Its rigid material and accurate dimensions prevent tooth wear or deformation (even under high torque), avoiding timing drift (e.g., delayed valve opening) that leads to poor fuel economy, increased emissions, or rough engine performance.
Support belt/chain tension: The pulley’s smooth, concentric outer surface (runout tolerance <0.1mm) ensures even contact with the timing belt/chain, reducing localized wear and extending the timing system’s service life (typically 80,000–120,000 miles for BMWs).

Compatible Vehicles

This Crankshaft Timing Pulley (OE: 11237548003) fits multiple BMW models across generations, including sedans, coupes, SUVs, and roadsters. Below is a consolidated list of applicable models, chassis codes, and year ranges:

BMW Model Series	Chassis Code	Applicable Years	Notes (Variants)
1 Series	E81, E82, E87, E88	2003–2013	Includes LCI (Life Cycle Impulse) variants
3 Series	E46, E90, E91, E92, E93	1997–2013	E46 (1997–2006); E90/E91/E92/E93 (2004–2013); includes LCI variants
5 Series	E60	2006–2010	Focus on LCI variants (2008–2010)
X1	E84	2009–2015	Covers full production cycle
X3	E83	2003–2010	Includes LCI variants (2006–2010)
Z4	E85	2004–2008	Full production cycle of E85 chassis

*Notes:

“LCI” refers to BMW’s mid-generation update (e.g., E90 LCI: 2008–2013), which retains timing system compatibility with pre-LCI models of the same chassis.
For 100% fitment accuracy, confirm via the vehicle’s VIN (Vehicle Identification Number) to match the specific engine variant (e.g., 2.0L N46, 3.0L N52 petrol engines—this pulley is designed for petrol engines, not diesel variants).*

Frequently Asked Questions

Q: How to determine if the bumper bracket needs replacement?

A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.

Q: What should be paid attention to when replacing the bumper bracket?

A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
