Is it just the aluminum fan that comes loose? Check the dowl pin hole in the
big fan. If it is worn, you might need to replace the big fan. Also check
the end of the crank where the fan goes on. It should be a light press fit.
Also, if the key/keyway in the crank is worn, the fan won't stay tight. In
this case a new crank is called for.
