Product Description
High-quality Timing Chain Tension Guide Rail 11311703717 for BMW 5 Series E60 520i M54 Engine
This premium timing chain tension guide rail with OE number 1131 1703 717 is a critical engine timing system component for BMW E60 520i equipped with M54 inline-six naturally aspirated engine. It is an essential engine overhaul spare part widely stocked by professional BMW repair shops and cross-border auto parts wholesalers with stable market demand.
Core Selling Points
High-frequency timing vulnerable part with sustainable repeat bulk orders
Timing guide rails are easily worn core maintenance parts for M54 engine vehicles. Original rails suffer surface abrasion, plastic cracking, deformation and fracture after long-term high-speed friction with timing chains and continuous high-temperature baking inside engine bay. Damaged guide rails cause loose timing chain clearance, obvious rattling noise from engine front cover, risk of chain jumping teeth, inaccurate valve timing and severe engine damage. Specialized BMW service garages and global spare parts distributors place recurring bulk orders all year round, bringing steady sales volume and attractive profit margins for dealers.
100% OE precise dimensional replication, direct installation without modification
Manufactured strictly following BMW original injection molding standards: overall length, chain contact arc surface, tooth profile, mounting hole spacing and wall thickness fully match genuine OEM 11311703717. No cutting, grinding or trimming required during engine disassembly and assembly, perfectly cooperate with timing chain tensioner to limit chain swing, greatly shorten timing system overhaul labor hours.
Compatible Vehicle Range
- Main matching model: BMW 5 Series E60 520i with M54B22 engine
- Interchangeable chassis: E46 3 Series, E83 X3, E39 early 5 Series, E85 Z4 fitted with M54 series engines
Reinforced high-temperature wear-resistant reinforced plastic structure
- Glass fiber reinforced PA66 engineering plastic body, excellent heat resistance, avoid softening and deformation under long-term engine high temperature circulation
- Surface solid self-lubricating wear-resistant coating, effectively reduce friction loss between timing chain and guide rail, slow down abrasion
- Integrated reinforced support rib design, greatly improve anti-fracture and impact resistance
- Standard positioning mounting holes, firm fixation without displacement during engine operation
- Precision molded chain limiting radian, effectively restrain chain transverse shaking to prevent tooth jumping
Stabilize timing chain operation to fully protect engine valve system
Cooperate with timing chain tensioner to maintain proper tension of the timing chain, eliminate excessive swing and vibration of the chain during engine operation. Keep accurate valve timing matching, remove abnormal rattling noise from engine front end, avoid valve collision and cylinder scrapping accidents caused by chain jumping teeth, and extend the service life of timing chain and related components.
Fully resolve typical guide rail failure faults
Perfectly fixes common M54 timing system malfunctions:
- Continuous obvious rattling noise from engine front timing cover after ignition
- Serious abrasion, cracks or breakage on original guide rail surface
- Loose timing chain leading to abnormal engine power attenuation
- Hidden danger of timing chain jumping teeth, which may cause valve top damage
- Abnormal vibration when engine accelerates at medium and low speed
Rigorous multi-stage factory testing & sufficient spot stock
Each tension guide rail undergoes high-low temperature cycle aging test, friction wear durability test, impact fracture resistance test and dimensional tolerance inspection before delivery, compliant with IATF 16949 international automotive quality standards. Mass ready stock supports mixed one-stop bulk procurement with timing chains, tensioners, sprockets, oil pump guide rails and complete engine overhaul kits. Custom neutral packaging and private label OEM services are available for cross-border wholesale buyers.
