Internal combustion engine with an engine block and a timing transmission with improved properties for removing and replacing the timing chain and method therefor

摘要

The invention relates to an internal combustion engine with an engine block and a timing control gear, the arrangement comprising a cover (13) for the timing transmission, the cover (13) has an edge and fastening means are provided for attaching the cover (13) for the timing transmission to the engine block which are slackable to allow the timing transmission cover (13) to be separated from the engine block sufficiently to allow access to the transmission means through a gap between the engine block and the edge of the timing transmission cover (13). Further, in the cover (13), there is provided a through hole (13a) arranged such that a fixing jig (14) extending through the through hole (13a) is in contact with the contact surface of the movable guide (7) can, when the guide (7) is moved to a relaxed position, which allows the transmission means to be removed from the sprockets (3, 4).
