I looked at the Harbor Freight website and could not find the machine. I found a listing for it on the Grizzly Tools website but the machine is now discontinued. You should still be able to purchase the motor assembly as a repair item. The part number is p8693056 and the listed price is $101.75. Contact Grizzly Tools and see if you can purchase it. It may take awhile if it is on backorder but it will make your lathe run the way a lathe should run and will be well worth the wait.
