I've just stripped and nearly finished rebuilding this on one of our Combo vans, I've done a lot of 1.7 cam belts and this has come as a bit of a shocker.
Why is it that they see fit to design a crank and Cam pulley arrangement that has no guide dowels or locking mechanism apart from the friction of the sprocket to mating surface?

Do they ever slip and cause havoc?

And how are you suppose to get hold of a tool to lock the crank? I made one as suggested but would prefer a robust well engineered solution.

Cheers for that, I do have the tools that you link to but the haynes shows another tool used to lock the Crank Pulley Boss whilst undoing the bolt and it's this one I had to make.

Do you reckon the Flywheel locking pin on its own would stand the torque of tightening the bolt? The Cam locking tools are not so positive in their location so I would not trust them to resist too much torque application.
