There is provided an idler pulley assembly 20 for use in a belt drive system (10, fig 1) on an internal combustion engine and which comprises an idler pulley 13 rotatably mounted on a spindle 21 which in turn is fixedly mounted on a support 22 capable of rotation about an axis off-set from the spindle axis. There is also provided a method of fitting a drive belt to a drive belt system including the idler pulley assembly. In said method, the drive belt is located around other pulleys, the support 22 is moved to a first rotational position which minimises the distance between pulleys and enables the drive belt to be located on the idler pulley 13, the belt then being tensioned by rotation of the support 22. |
