Crankshaft Alignment Tool 1/2in Drive for Mercedes & MAN

A crankshaft alignment tool for manually rotating the engine crankshaft during timing and service work on selected Mercedes and MAN engines. Used with a 1/2in drive ratchet, it gives controlled hand rotation when checking crank position during engine timing, strip-down and rebuild jobs.

Used for workshop servicing, engine maintenance and timing-related repairs, this tool is suited to mechanics working on larger commercial or specialist engines where accurate crankshaft positioning matters. It is applicable to MAN 12 cylinder engines and Mercedes 6, 8 and 10 cylinder engines, making it useful when carrying out timing checks, engine assembly work or other repair tasks where the crank needs to be turned by hand rather than powered rotation.

The crankshaft tool is supplied with 2 gears and is intended for use in conjunction with a 1/2in drive ratchet. That setup helps provide steady, controlled movement while working through engine timing positions or aligning components during servicing. The listed model coverage includes 401, 404, 407, 409, 421, 424, 444, 427 and 447. For regular engine work, having the correct alignment tool to hand helps avoid makeshift methods and keeps the job more controlled and straightforward.
