Hey, I KNOW they are easy - Which is what I meant by make sure it is
in better shape than what you took out and replacement (of the
brushes) is the best bet.

Sadly, replacing the brushes doesn't always fix them when they get to
the point they don't run any more, because the commutator gets worn
/burned/ gouged to the point it cannot be readilly cleaned up. Then a
good used one (check and replace brushes if necessary) or a new one is
required.

When having a used unit installed by a scrap yard you want to make
sure they warrantee both the part and the labour - and they have
actually checked the part before installing. The good ones do - but
MANY do not. The labour, generally, is worth more than the (used)
part.
