As others have pointed out, this is not possible to do at home, period.

For starters, a hard drive must never be opened in anything other than a
special clean room because a speck of dust landing on the platters will
cause a head crash which will destroy the surface integrity of both heads
and platters.

Secondly, dismantling the mechanism will severely damage the heads and
platters, special tools and jigs will be required to accomplish this- there
is no room for error.

Thirdly, even assuming one managed to physically transplant a new mechanism,
the drive will never read or write data again because of the contamination
of the previously sealed drive and the alignment of the mechanism.

The drive is now junk, you'll have to forget about the data on it I'm
afraid.
