Abstract: A chain tensioning arrangement arranged in a timing case for an internal-combustion engine which acts upon a timing chain that can be driven by the crankshaft of the internal-combustion engine. The chain tensioning arrangement provides a simple device with respect to assembly and operational reliability. The chain tensioning arrangement includes a tensioning member which can be adjusted between a mounting position, releasing chain tension and a tensioning position acting upon the chain. In the mounting position, the tensioning member is clamped by a releasable locking pin which extends beyond the floor of the timing case of the internal-combustion engine.
