• New timing components are generally preferred during a complete engine overhaul.

🔌 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 timing-chain wear:

• 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

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

📦 Condition

• Genuine Suzuki Marine used part

• Pre-owned internal engine component

• Oil staining and normal surface marks may be present

• Measurement against the factory wear limit is required

• Replacement with a new chain is recommended where wear history is unknown

• Supplied in protective or equivalent packaging
