Layout and Location

Hydraulic chain tensioner

In G20DF engine, the hydraulic auto tensioner is used to keep the tension for chain drive system of

engine. The auto tensioner is operated by the spring in tensioner and the hydraulic pressure.

Clamping rail

Installed between intake

camshaft sprocket and

crankshaft sprocket

5) Chain Rails

The chain rails are used for optimizing the movement of chain drive system. And they also prevent the

chain from contacting each other when the chain is loose, and reduces the chain wear. The chain rail is

normally made of PA (Polyamide nylon), and PA66 and PA46 are used for the chain rails in G20DF

engine. For the tensioner rail, PA46 is used to provide high anti-wear function and high strength since

the load to the rail is huge. Ther is an open area for shoulder bolt hole in the clamping rail. The chain

rails are installed by shoulder bolts.
