I have a Delta 28-203 bandsaw with a 3/4 HP motor in it. What is
involved in upgrading to a 1 or 1.5 HP 1725RM motor? Can I just take
the pulley off of the old one and put on the new one? Any recommended
As long as you keep the same motor frame size, you will have no
problems since the mounting feet bolt pattern will remain the same.
You probably have a 56 frame which will have a 5/8" shaft.
Just make sure you have physical clearance between saw frame and fan
end of motor.
Yes and no. You need a motor with the same frame size for the pulley to fit
or you need a new pulley with the dame diameter but bore to fit the new
motor. The new motor has to fit the mount also. If you have a 56 frame,
get another 56 frame. Be sure you have the wiring to support the larger
load also. You can find a lot of information at the Grainger web site.
Excellent, thanks. BTW, this is an older made in USA model with
enclosed base, not the open stand model sold in the box stores today.
It looks identical to the 475x model sold today with the 1.5HP motor.
If possible go to 220volts so the wiring will not have be upgraded.
And with going to 220 you will need a new switch that breaks both legs
of the power. Home Depot now sells motor rated switches.
Twice the current.
I/you can almost bet that the present wiring is just enough for
3/4HP. Going to 220Volts will negate this if the voltage rating of the
wiring is enough - which I would assume it is. Probably 300 or 600
Lots of things to think about. What size is the wiring now? Including
