Nailhead pulleys

I have a 401 Nailhead that currently has 3 groove pulleys. Does anyone know if a 1 groove pulley was ever available either factory or aftermarket?

 

When my 401 nailhead was in the shop for a rebuild I had the machinist trim off the outer pulley sheave. There are two sheave crank pulleys for sale on ebay, not sure about singles.

yes they made singles

 

Thanks for the info. Are the pulleys for all nailheads interchangable?

 

Just about any big machine shop can make what you need. In the past I have had them made with no problems.

 

I've been looking for a 2 groove crank pulley for my 322 - have tried some newer pulleys (401) which do NOT fit the 322 (bigger hole, wider bolt spacing), So, I would have to ***ume all pulleys do not interchange !! I believe water pump pulleys do, but not crank ! Unfortunately there are a lot of 322 single pulleys out there, in fact, I would trade you !!
