One-stop Purchase Timing Chain Left Lower Guide Rail 11317533489 for BMW 7 Series E66 740Li (N62 Engine)
This OEM-standard left lower timing chain tension guide rail with OE number 11317533489 is specially designed for BMW E66 chassis 740Li equipped with N62 4.4L V8 naturally aspirated engine, installed on the left cylinder bank (Cylinders 5-8) of the timing system. As a core wearable part for engine timing overhaul, it enjoys stable repeat orders globally, widely stocked by luxury car repair workshops and cross-border auto parts wholesalers, and supports one-stop bundled procurement with complete timing repair kits.
Core Selling Points
Hot-selling timing vulnerable part suitable for combined one-stop ordering
Timing guide rails are high-failure consumables for BMW N62 V8 engines. Under long-term high-speed friction with timing chains, continuous erosion by high-temperature oil mist inside the engine compartment, extrusion from cyclic tension and body vibration, the wear-resistant sliding layer of the original rail will gradually wear thin, peel off, crack and deform.
Damaged guide rail will cause loose timing chain, persistent rattling/rumbling abnormal noise from the front engine cover, deviation of valve timing, rough idle, power decline and increased fuel consumption. In serious cases, the timing chain jumps teeth, which will collide with pistons and valves directly and lead to engine scrapping.
Most buyers purchase this left guide rail together with the right tension rail (11317533462), timing chain, hydraulic tensioner, sealing gaskets as a full set in one shipment to reduce procurement and logistics costs, bringing steady profit margins and low inventory risks for dealers all year round.
100% OE precise dimensional replication, direct bolt-on installation without any modification
Strictly produced according to BMW original factory technical specifications: overall curved radian, mounting hole spacing, sliding track radian, wear-resistant layer thickness and fixed buckle structure are fully consistent with genuine 11317533489; interchangeable old part number: 11317504461.
No cutting, trimming, bending or post-installation timing calibration is needed. It perfectly fits the timing chamber of N62 engine cylinder head, cooperates with hydraulic tensioner to keep the timing chain under constant proper tension, greatly shortening engine timing disassembly and maintenance hours.
Applicable Vehicle & Engine Range
- Matched Engine: BMW N62 4.4L / 4.8L V8 gasoline engine
- Main Applicable Model: BMW 7 Series E66 740Li (Long wheelbase version)
- Extended Compatible Models: BMW E65/E66 745Li/750Li, E60 545i/550i, E63/E64 645Ci/650i, X5 E53/E70 4.4i/4.8i and all vehicles equipped with N62 series V8 engines
- Installation Position: Left bank lower timing chain tension guide rail (for cylinders 5 to 8)
Reinforced Durable Structural Design
- Glass fiber reinforced PA66 nylon bracket main body: High rigidity, anti-deformation & anti-cracking, resistant to long-term high-temperature engine oil corrosion
- Imported PTFE wear-resistant sliding lining: Ultra-low friction coefficient, wear resistance far exceeds ordinary plastic materials, effectively reduce chain running noise and extend service life
- Integrated injection molding process: The bracket and sliding layer will not delaminate or peel under long-term reciprocating tension
- Standard reserved bolt holes: Firmly fixed after tightening, no displacement caused by engine vibration
- Pre-assembled finished product, ready for direct assembly without extra accessories
Stabilize Timing System & Effectively Protect V8 Engine
- Cooperate with hydraulic tensioner to apply lasting moderate tension to timing chain, prevent chain loosening, tooth jumping and falling off
- Limit the running track of timing chain, reduce swing amplitude and eliminate abnormal rattling noise during engine operation
- Maintain accurate valve opening and closing timing, stabilize idle speed, restore original power output and fuel economy
- Avoid major engine collision damage caused by timing failure, drastically cut the risk of expensive full engine overhaul
Completely Solve Common Failure Symptoms of Timing Guide Rail
- Continuous humming/rattling noise emitted from engine front timing cover
- Rough engine idle, obvious jitter during acceleration
- Vehicle power attenuation, insufficient power for climbing and overtaking
- Fuel consumption rises sharply, exhaust emission deteriorates
- Timing chain elongation speeds up, vehicle triggers timing system fault codes frequently
- Hidden danger of chain tooth jumping leading to permanent engine damage
Rigorous Multi-stage Factory Testing & Ample Spot Inventory
Each guide rail passes reciprocating friction wear test, high-low temperature cyclic aging test, engine oil immersion anti-corrosion test and vibration fatigue inspection before delivery, complying with IATF 16949 international automotive quality management standards.
Sufficient spot goods support one-stop mixed procurement with timing chain, hydraulic tensioner, dual-side guide rails, timing cover gaskets and complete N62 engine timing overhaul kits. Neutral packaging and private label OEM customization services are available for global cross-border wholesale customers.
