Did You notice that You got a couple answers like, get your wrenches out, its got to come apart, You broke something?

They were not trying to give you a short answer or a smart answer. Thats the only answer anyone can give You at this
point . No one, not You! not me! or anyone else can tell You at this point that You need another motor or that yours can't be repaired.

As Tech said. Get Your wrenches out! Find the problem, Then make your determination as to the solution.

Good Luck!
