I just recently put a link belt on my contractors saw and was doing some misc tune-up when I noticed a fairly perceptible misalignment in the arbor to motor pulley.
The weight of the motor on the opposite side of the pulley is causing torque, which in turn causes the pulley side to flare out at a slight angle.
When I lift the motor to relieve tension, the pulleys come into alignment and I can see the mounting bracket adjust accordingly.
Any suggestions would be greatly appreciated.
