Engine accessory drives are used with internal combustion engines to drive one or more accessories and are conventionally driven off a front end drive assembly. However, driving the accessories off the front end drive assembly has implications in respect of both increased engine noise and extended engine length. An engine accessory drive in accordance with this invention reduces engine noise and engine length. An engine accessory drive for transmitting a force between a first end (2) and a second end (3) of an engine (1) comprises a primary drive (18) locatable at the first end (2) of the engine.
