TIMING CHAIN, CHAIN TENSIONER CONSTRUCTION [MZI-3.5]

Timing Chain

• The timing chain tension is maintained constantly by the chain tensioner.
• The tension of the timing chain is constantly maintained using oil pressure and spring force in the chain
tensioner.
• There is a timing mark on the surface of the intake camshaft sprocket on both banks, and on the surface of the
crankshaft sprocket. Timing can be performed by assembling the timing chain based on these timing marks.
