🔌 Function

The timing chain transfers crankshaft rotation to the camshafts at the correct ratio.

Accurate timing is essential to prevent piston-to-valve contact and maintain compression, starting performance and power output.

⚠️ Common Signs of Failure

• Rattle during start-up
• Persistent chain noise
• Incorrect valve timing
• Difficult starting
• Reduced power
• Camshaft-position fault codes
• Uneven compression
• Visible chain elongation
• Worn or damaged chain rollers
• Metal debris around the chain drive

🛠️ Service Notes

Recommended checks before installation

• Measure chain elongation against the service limit
• Inspect every roller and side plate
• Check the crankshaft and camshaft sprockets
• Inspect both chain guides
• Check the tensioner and automatic adjuster
• Align all timing marks exactly
• Rotate the engine by hand before starting
• Confirm valve timing after assembly
