I replaced this motor and squirrel cage fan out of this Despatch Oven. The circulation fan over the years had become encrusted in dust causing it to be out of balance. This wrecked the bearings on the fan. I bought a fan puller and took off the old fan and replaced both parts. The old motor was less efficient than new one, so I opted for the latter. After putting it all back together it runs really quiet.
