The manual I have is probably the same as yours, it does have the
instructions for mounting the motor and determining saw speed. The only
problem I can see in converting a direct drive to belt drive is providing a
bearing for the lower belt. Mine has a large bearing holder that bolts in
place of the motor in a direct drive. At first it was difficult to get it to
track, but I finally got the hang of it. Although I have an older Delta 14"
saw I find myself using the Inca most of the time. Jim A.
