Timing Belt Auto Tensioner

•
A timing belt auto tensioner has been adopted to maintain timing belt tension constant.
The timing belt tension is released by turning the auto tensioner counterclockwise with
the aid of an Allen wrench (with max. 39 Nm apply force). The turned back tensioner is
secured by inserting a fixing pin with 6 mm diameter into the appropriate bore (No. 3 in
figure below).
