Personally no , but you can get a “thread pitch” tool and also measure diameter of the shaft , that should give you a rough thread size. You can also use the nut spanner size to have an idea.
Eg. 13mm spanner on a bolt means it should be M8 ID x 1.25mm pitch (generally)
I can’t confirm if TE uses reverse threads on the flywheel side as i never owned one, i do know though the right side of the crank either the clutch or oil pump pulleys are reverse nuts.
