This OEM-grade timing chain sliding guide rail with OE number 11317504475 is a key wearable component of the timing system, exclusively designed for BMW E66 chassis 750Li fitted with N62 4.8L V8 naturally aspirated engine. It enjoys consistent strong demand across the global auto aftermarket, widely purchased by professional luxury car repair workshops and cross-border auto parts wholesalers worldwide, and supports one-stop bulk ordering paired with full timing overhaul accessory sets.
Core Selling Points
Hot-selling timing consumable ideal for bundled one-stop procurement
Timing slide rails are vulnerable wearing parts widely seen on BMW N62 series V8 engines. Under long-term continuous friction against the timing chain, erosion from high-temperature oil vapor inside the timing chamber, repeated tensile stress and engine operating vibration, the wear-resistant lining on the rail surface will gradually wear thin, harden, crack and peel off.
A defective slide rail will lead to loose timing chains, persistent rattling noise coming from the front engine timing cover, distorted intake and exhaust valve timing, rough idle, engine shaking, weakened power and higher fuel consumption. In severe cases, the timing chain jumps teeth, which will smash valves and pistons, triggering irreversible engine damage and costly major overhaul expenses.
Most buyers choose to purchase this slide rail together with matched tension rails, timing chain, hydraulic tensioner and sealing gaskets as a complete set in one order to cut procurement and logistics costs, bringing steady profit margins and low inventory risks for dealers all year round.
100% OE identical dimensional standard, direct bolt-on installation without any modification
Manufactured strictly following BMW official OEM technical specifications: overall curved profile, mounting hole spacing, sliding track radian, wear layer thickness and positioning buckle structure are all fully consistent with genuine 11317504475. No cutting, trimming, bending or post-installation timing calibration is needed. It fits seamlessly inside the timing housing of the N62 engine cylinder head, works with the hydraulic tensioner to maintain the timing chain at the optimal tension constantly, greatly shortening engine disassembly and maintenance working hours.
Main Applicable Model: BMW 7 Series E66 Long Wheelbase 750Li
Interchangeable Compatible Models:
BMW E65/E66 745Li, E60 545i/550i, E63/E64 645Ci/650i, X5 E53/E70 4.4i/4.8i and all vehicles equipped with N62 V8 power assembly
Reinforced Durable Structural Design
Glass fiber reinforced PA66 nylon main frame: High structural rigidity, resistant to deformation and cracking, withstand long-term erosion by high-temperature engine oil
Embedded imported PTFE wear-resistant sliding lining: Ultra-low friction coefficient, far superior wear resistance than ordinary plastic materials, effectively reduce operating noise between chain and rail
Integrated injection molding technology: The base and wear-resistant layer will not delaminate or fall off under long-term reciprocating friction
Precision prefabricated bolt holes: Firmly fixed after tightening, no offset or shaking caused by engine vibration
Pre-assembled finished product, ready for direct mounting without extra accessories
Core Functions & Benefits
Restrict the running path of the timing chain, suppress excessive swinging, keep proper tension to avoid chain jumping teeth and falling off
Eliminate abnormal rattling and buzzing noise generated during timing chain operation
Maintain precise valve opening and closing timing, smooth idle operation, restore original vehicle power and normal fuel economy
Effectively prevent severe engine collision damage triggered by timing system failure
Fully Resolve Common Failures Caused by Damaged Slide Rail
Continuous rattling noise emitted from the front end of the engine
Unstable idle speed, obvious engine jitter during acceleration
Declined vehicle power, slow acceleration and weak climbing ability
On-board control system frequently stores timing system fault codes
High potential risk of timing chain tooth jumping leading to engine scrapping
