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.
