Re: Finding a mechanical engine fan by dimensions

   OK , if I understand correctly the 4 slot flange bolts to the pump
and the fan bolts to a surface that is hidden by the fan  . Got a mill
and a boring head ? Is the current fan's base circle diameter big enough
to drill the bolt pattern of the new clutch ? I could adapt that fan to
that clutch in my shop .

Two notches in the fan hole might get it over the flange without losing centering. Does the clutch body size allow you to tilt the fan and slip an edge of the hole into one of the slots to gain clearance?
Perhaps you could make an adapter disk on the lathe large enough to attach to the fan with the proper center and mounting holes and rough out the fan hole to a scribed line with hand-held tools, as I have to do to mount a round meter in a panel too large for the mill. Also make a 1 or 2 piece stepped plug to center the fan on the adapter plate and drill the matching hole pattern before opening up the hole.
