I think the flywheel tool might be just to prevent the pin being bent whilst tightening the pulley bolt? Thats its job on the diesel engine. It appears in the turtorial linked above its also being used to set the crank position too? i can only assume on this engine the flywheel tool must only slot into the flywheel at the same point the locking pin does.

I think i see your dilemma, You mean you arent able to turn the crankshafts to the right position when a piston is at TDC?

Id first rotate the crank so that no piston is at TDC. ie back off a little from the crank locking pin. Then set the camshaft positions, the camshaft tool should only fit when both camshafts are in correct orientation. Then bring the crankshaft back into position against the locking pin.

You should google this yourself though, dont use me as a single source of info. Ive only limited experience on a few motorbikes and cars, and certainly not this engine.
