I replaced a broken motor coupler, now the washer works, but during the spin cycle there is a loud high-pitched squeak and the smell of burning rubber. Is normal "break-in" for a new coupler or is there something else wrong?

I'm a novice and don't know how to "jump" out the lid switch, but I took off the cabinet and washtub cover. when I spun the tub by hand it was very tight, then loosened a bit, but I could see the plastic piece in the clutch maybe slipping. I ran the washer on spin and the squeak is gone but now I hear clicking and still a faint smell of burning. Could it be the clutch? I know I can replace that, but if it's the brake shoes, that might be too much for me!
