Much of the time the fan is sold as part of the armature, which is probably the most expensive part on rhe router. I agree with the previous suggestion to look for a Craftsman or Ryobi donor that is being sold for parts. Sears uses the Ryobi part numbers. Find your armature part number and if you find a possible candidate, look up the armature number to see if you have a match. If the fan is plastic it might be hard to salvage it unbroken. Yours probably fell apart. There are some armature fans for sale but you have to match the hub and blade sizes and that might be very tough.
