I doubt that I can explain it correctly, but here goes:

I got from my Dad a "Pulley Alignment tool" which worked out great for my
bandsaw.
he made it from metal in the factory he worked at back in the 60's for use
on metal working machines.

Imagine the following.
1. two pieces of wood, shaped like small versions of the top of a crutch
but
can fit the groove of your pulley but not long enough to touch the belts.
Curved and then shaped with a round over router bit. Bottom (the part
away
from pulley) could be flat.
2. Now to the two pulley crutch tops, fix a 1/4 inch water pipe cap. For
those with Fostner bits or Brad Point bits, make a recess for the pipe cap
which needs to be flat bottom hole big enough for the copper pipe cap.
Otherwise, drill a hole and use a round head screw.
3. use a thick wall 1/4 inch copper pipe. cut in two. Make it easy on
your
self and cut it so it will be easy to get a wrench to the nuts in step 6.
Aside: length of pipe to fit your needs. may have to cut pipe two or
three
times.
4. use a threaded rod with nuts and washers between the nuts and copper
pipe.
5. threaded rod goes between the two copper pieces of pipe.
6. Use wrench on nuts and threaded rod to force the pulleys apart.
7. Don't over torque the nuts.
8. Align motor, and tighten the bolts. and then remove the pulley
stretcher.

Sorry if I am not clear.
