Hi Gary,
I have one of those but it's buried in a packing crate so cant really check...
a realy good machine.....Dewalt bought the Germ/Austrian compy who made the original....I think it was Elu....?
but from pictures and memory a standard motor could be adapted...
it's easy to get a new motor that is foot mouted (like normal) or face mounted....
Just take it off and visit a motor suppliers locally....
they will prob have it in stock and should u need a new or modified pully (shaft size could be different) they will also sort that out...
Dont bother with Machine mart etc....
the last new motor I bought had both types of mounting and was a little over £100...
made in Italy.....
PS the orinal machines came with a 240v -440v (dual voltage motor) but u will only need a 240v motor so cheaper...
good luck.....
