Atlas Drive Side Crankshaft Thread

[jms]

Hi
Can anybody confirm that the Atlas drive side crank thread is 5/8”-20 BSC and that it is the same thread as the gearbox drive side mainshaft. Thanks

The same thread is used on the crank end for the alternator rotor and to hold the clutch hub and basket on the gearbox mainshaft. I've cut the shoulder off of the nut that holds the rotor on the end of the crank and used the thinner nut on a NEB clutch. I'm not sure about the 5/8-20 BSC spec, but they are the same thread.

Thanks Schwany. I was making an adapter that will allow me to bolt up a degree wheel to the crank with bolt that I have
