OLDER Three or single phase OEM motor information is getting more and more difficult to find. New technologies and new types of motors are often blended in the same operation, or operation, and can be somewhat confusing.
For over thirty years I have been involved with the repair and diagnosis of motor/apparatus mechanical issues. There are always new issues.
A brush can increase the operating life of a motor by a factor of 2 or more. Simply sweeping the contaminates or materials from a process, off the motor case, will allow the motor to cool itself as designed. however a "hot" motor is not necessarily a "bad" motor.
Differences in the motor code number or speeds require additional consideration in starting methods and choices of control. The number of starts a motor can withstand in a defined amount of time is frequently overlooked. Motors do fail on their own. However a significant amount of motor failures are the result of something preventable. As well, the cause of failure in rarely diagnosed.

Derek, Almost but not quite enough information. First I thought momentary switch, were pushing start activates the contacts, starts the motor, but does not "seal" or mechanically latch, so that the
I see this is a poor diagram makes no sense to me, Firs thing is to get the motor connected for the voltage you want, 5 and 8 motor leads are the start windings and the two that will need to be
You want variable speed? The model looks like a three phase motor. IF it is a shop with three phase you can use a VFD Variable Frequency Drive, If it is single phase there is not much speed control
Look at your pulleys if you can find a ridge in the side of either pulley it is bad, and will tear up a belt in short order, I cannot tell if the belt is just old and deteriorated or torn from ridges
Rhonda The clue might be in the reason and or condition of the old belt Did it break? Was it frayed badly? What method tightens the belt? Do you know there are different sizes of belts
