The Big Nut of a 15-Six Engine

Undoing and tightening the round castellated nut that holds the starter gear hub onto the crankshaft of a Traction Avant 15-Six engine. Without the proper equipment this is almost impossible. With some ingenuity and the right tools it can be done properly -and is well worth the effort. A torque of no less than 300 Nm is required to prevent accidental running loose of this nut, which could cause serious damage.
