TIMING CHAIN, CHAIN TENSIONER CONSTRUCTION [MZI-3.7]
id0110c5101200
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.
Camshaft Timing Chain
• The camshaft timing chain tensioner is positioned between the intake camshaft sprocket and exhaust camshaft sprocket.
• There is a timing mark on the underside of the intake camshaft sprocket on both banks, and on the surface of the exhaust camshaft sprocket on both banks. Timing can be performed by assembling the camshaft timing chain based on these timing marks.
• To facilitate removal/installation of the camshaft timing chain, insert a clip or similar item into the hole of the camshaft timing chain tensioner to retain the timing chain tensioner force.
