Generator fan

[sweeperman210]

Hi I have a 1980fc33 with a12.5 kohler gen. A previous owner changed the
stock cooling fan with a plastic one which also reversed the direction
of air flo. I am not happy with the cooling performance of this set up
gen. will run up to 200 deg. with two A/C's on I have checked and
tightened water pump belt on the perkins engine. I would like to find
out the part number for the stock fan and hub assy. and where to
purchase one. Thank you Mark
