The 20-3 TM says "NOTE: Discard fan clutch assembly PN 1090-08000-03 and replace with fan clutch assembly PN 1090-08000-01."
I had the older -03 fan, and am replacing it with the newer -01 model.
The TM also says "NOTE: Discard engine fan PN 4035-41393-74 and replace with engine fan PN 12421972." Is that just because of an improvement, or because the new clutch only mates up to the new fan?
UPDATE: Read future posts... the old fan DOES NOT fit on the new clutch.
