A tensioner force assembly for applying tension to an engine timing chain that changes the direction of the force acting on a chain tensioning arm such that the tensioner piston is oriented in parallel with the long axis of the crankshaft is provided. The tensioner assembly includes a crankshaft sprocket attached to the crankshaft, a cam shaft sprocket attached to the cam shaft, and a timing chain engaging the sprockets. A timing chain tensioner is pivotally attached to the engine block. A chain tensioner mechanism is provided that takes up timing chain slack. The chain tensioner mechanism includes a pivotable force transfer mechanism, a cylinder body having a long axis parallel to the long axis of the crankshaft, and a reciprocating tensioner piston in the body and engaged with the transfer mechanism for moving the transfer mechanism to apply required tension to the timing chain through the timing chain tensioner. |
