[FC] More blower fan difficulty....

[Merv and or Loretta]

OK, to date, I have successfully rounded off one of the bolt heads holding the
blower fan assembly together. A bolt extractor didn't work, except to shave a
further 1/16" off the diameter of the bolt head.Then, I punched and drilled a
1/8" pilot hole into the bolt, followed by a 3/8 drill bit. I broke it. Then I
had to really put some grunt into pulling the remaining part of the broken bit
out of the hole. A perhaps gentler approach with my only other 3/8" bit
succeeded. A couple of selective taps with a cold chisel and the last of the
head fell off. I tapped and smacked the pulley and it finally fell off.
NOW the damn fan itself won't come off. It is like someone glued the thing on
to the hub.
Because I have never worked with magnesium and especially 40 year old
magnesium blower fans, I need to know just how tough these things are and
exactly how hard I can bang on it to try to break it loose.

Would you describe it as a :

thump
thwack
smack
sharp rap
resounding bonk
thorough beating
smallish stick of dynamite
large stick of dynamite

Your input would be appreciated..... <S>
