4 non-working Oster motors (Seattle Crown Hill)

Four Oster kitchen center bases, three of which seized up after making double batches of ice cream (you’d think I’d learn). Want to practice motor repair with a handy supply of spare parts? Possibly just needs oil and cleaning? There’s obviously a market for these if you can get them working again (not just me). Or simply the joy of tearing things apart and learning how they work. No judgment!
