The crankshaft pulley bolt is done up to 200 nm and then 90 deg’s. It didn’t move.

Worked a treat but only after we ground away the area around the lower pin on the tool to stop it fouling the gearbox casing. Took a while to figure out why it wouldn’t fit as you can’t see in there but once we figured it out it was fairly easy to rectify. You’d be stuck if you couldn’t grind away the tool to stop it fouling the gearbox.

Perfect for mercedes tech

Great value for a much needed tool to make the job that much easier. A fraction of the cost if purchased at an MBZ dealer.
