Timing chain kit M272 for Mercedes-Benz

OE spec timing chain kit, engineered for Mercedes Benz vehicles with the M272 V6 petrol engine, 2.5, 3.0, 3.5. Restores precise valve timing, quiet starts and reliable performance after chain stretch or guide wear. Sold per kit, variant specific to engine code and year.

What this is / isn’t:
Included: Primary timing chain, fixed and pivot guides, hydraulic tensioner, guide pins or rails, front cover seal or gasket where supplied.

Important: Match by VIN and engine code M272. Early engines may have different guide designs and tensioner specs. Some model years also tie in with balance shaft sprocket updates, check your VIN and OE numbers before ordering.

Key Features:

• OE matched geometry: Correct chain pitch and guide profile for accurate cam timing.

• Quiet operation: Hardened pins and low friction guide faces reduce start up rattle.

• Stable tension control: Calibrated hydraulic tensioner maintains chain load across rpm and temperature.

• Leak resistant service: New front cover seal or gasket where supplied to help prevent seepage after reassembly.

• Exact fitment: Direct replacement components for a no mod install when used with factory timing tools.

Always order by the exact OE part number on your vehicle or confirm via VIN.

When to replace a timing chain kit:

• Rattle at cold start or warm idle, chain slap from the timing cover.

• Fault codes for cam crank correlation, P0016, P0017, camshaft adjustment range errors.

• Retarded cam timing on scan data, rough running, poor fuel economy.

• Metal debris in the oil filter, guide material found during service.

Installation notes, pro tips:

• Use correct crank and cam locking tools, follow factory timing marks and torque specs.

• Replace one time use fasteners, crank bolt and cam bolts where specified.

• Clean sealing faces, apply approved sealant to the front cover, allow cure time.

• Change engine oil and filter after repair, use Mercedes approved oil, MB 229.x spec.

• On early M272 units, inspect the balance shaft sprocket for wear while open, address if needed.

• Clear adaptations, road test and recheck for leaks or stored faults.

What’s included, not included:
✅ Timing chain, guides and hydraulic tensioner, front cover seal or gasket where supplied
❌ Oil, sealant, crank bolt, cam phasers, water pump, belts, auxiliary hardware unless listed

Q&A
Q1: Will this fix the cold start rattle?
Yes, when rattle is caused by chain stretch or worn guides. Ensure the correct tensioner is installed and timing is set precisely.
Q2: Do I need special tools?
Yes, cam and crank locking tools and a torque angle gauge are required to set timing accurately.
Q3: Can I reuse the crankshaft bolt?
Not advised, it is usually torque to yield. Replace with new where specified.
Q4: Do I need to change cam phasers too?
Only if diagnostics show excessive wear or faults. Many repairs are resolved with the chain, guides and tensioner.
