How to know if crankshaft is lined up correctly!

Before locking the crankshaft in place. Remove the plastic cap on the gearbox housing, its an inspection hole that allows you to view the clutch plate and flywheel. The picture below shows you what it all looks like when the crankshaft is correctly aligned. You are looking to make sure the arrow on the gearbox housing (I've used a dab of paint to highlight mine in white) is lined up with a groove in the clutch plate.
