Using a larger sheave is not likely to be a problem. You
want one with about double the circumference of the
one on the faster motor.

In situations where the faster motor is already using
a large sheave to drive a shaft at 10,000 rpm or more,
going to a slower motor with a larger sheave could
introduce balance issues. A planer cutterhead is
likely set up to run at about 5000 rpm.
