Crankshaft Rotating Tool for Volvo D9A D12 D16C OEM 9996959

A crankshaft rotating tool for selected Volvo commercial vehicle engines, used when the engine needs to be turned by hand in a controlled way. This crankshaft tool engages through the flywheel ring gear and is equivalent to OEM 9996959 for the stated applications.

Used during workshop servicing, inspection and repair work, this tool helps when lining up engine positions, carrying out timing checks or turning the crankshaft manually where access is limited. It suits trade use on Volvo commercial vehicles and is a practical option for engine maintenance jobs where steady, controlled rotation is needed rather than relying on powered turning.

The tool is made for Volvo 6L and 12L engine applications including D9A, D12, D16C and FM 360 8x4. A 1/2in square drive means it can be used with standard workshop ratchets and breaker bars, which makes it easier to fit into existing tool kits without needing a dedicated handle. The purpose-made layout is intended for engaging the flywheel ring gear on the listed vehicles, helping with repeated servicing work and making manual engine positioning more straightforward when common jobs come up.
