It will come off easily with an 18" pipe wrench. Besides, the body

torch the freewheel carrier it till it smokes
fill the hub with ice
allow unit to cool
apply pc blaster on the crack holding carrier down off course
let stand in this postion ummm as lonfg as possible
re torch but try to heat the carrier not so much the hub. timing and
finesse.
get your moves together for the wrech act
wrench while hot that is to say right after turning the torch off.
then throw it away and get a new one.

gee i dunno. that's what did i. i now can rebuild a perfect freewheel

the question is the chain shot? but that's the same route as
rebuilding freewheels in the dark? right?

hey look kid, the new derays are two pivoted and they...
