Yes, it will work on that machine just fine. The 500GR has built-in 3:1 gear reduction. This makes it more powerful than it looks. It also limits the top speed of the motor to 1500 RPM.

The SewPro 500GR mounts a little closer to the table than a clutch motor. You will lose one inch of belt length, if the motor feeds the machine directly, without a speed reducer. If there is a reducer in the system the belt change may be negligible and easily compensated for via the motor adjuster bolt. If it is feeding all the way up to the flywheel on the machine, buy a 1" shorter belt. If the pulley on the original motor is larger than 2 inches, subtract another inch for each inch that the SewPro is smaller.

In my case, I replaced a clutch motor that had a 2.5" pulley with the SewPro motor and a 2" shorter belt. This positioned the motor a a favorable angle for the pedal rods to pull smoothly.

Doh! I almost forgot the last question you asked!

The existing belt will have a number after a letter. The letter probably is M. The number indicates the length of the belt, at the inside of the tapered belt's circumference. For instance, if the original says it is an M44, and the original motor has a 2" pulley, you would then order an M43 belt with the motor. If the original pulley is 2.5 or 3 inches, you would order an M42 belt (assuming a 44" to start with). The threaded adjuster allows for about 1.5 inches adjustment, up or down from the center point. But, the good operating angle occupies a range of about one inch, from the center down. Each pedal setup may differ from others and your floor pedal may allow a full range of adjustment, up or down, without binding. Mine didn't.

I re-read the entire thread and see that a couple of us mentioned where to get the SewPro 500GR motor, but nobody gave you the phone number. Toledo Industrial Sewing Machines: 866-362-7397. Tell them you heard about the motor here. Be sure you ask for the 2" pulley and remember what I said about getting a shorter v-belt.

Will Do!! Thanks! I will let you know how it all goes.

The SewPro 500GR only draws a single watt when not engaged. It draws 300 watts at full load. Mine has never even gotten hot to the touch. By contrast, the 1/2 horsepower motor it replaced drew about 550 watts and could warm my expando in idle.

The motor makes no sound in idle and it's easy to forget it is switched on. Remember to switch it off when it's not in use. You wouldn't want your kid or pet to accidentally push on the floor pedal and start the machine running.
