What size spanner for the crankshaft nut

[chicken]

What size spanner would I need for the crankshaft nut (starter dog).
Any ideas ?

A 1 11/16" or 43mm socket will fit. An impact wrench makes it much easier. An alternative would be a "striking/slugging wrench" in the same size.

The nut holding the front pulley to the crankshaft is a large and somewhat odd size. Its a WHITWORTH 1 1/8 inch nut. A "standard" AF size 1 11/16 inch may be used as others have said. The Whitworth would probably be nearly impossible to find and extortionately expensive in the US- it was hard enough finding one here....
