There are two things that can be done to preserve a machine:  Keep the 
original parts in the machine even if it no longer works.  Revive the 
machine even if it requires replace a classic component that is no longer 
available with a current replacement.

In the second case it becomes important to document what was done and why 
but both are valid ways to preserve machines.

To replace an original part with a different part with no valid reason it is 
a shame, part of history is lost for no good reason.
