You may need to create new mounting brackets for the fans depending on the vintage of the multiquip incubator. Replacement Motor for Post 1985 Incubators, Pre 1985 Multiplo incubators may require a new bracket for mounting. Screws supplied must be used for mounting and no other screws. Other screws may damage the motor windings and make void the warranty. Not suitable for the Multiquip hobby hatcher or wooden incubators with the fan belt.
Important note: When installing this fan motor it is important to use supplied screws to mount motor. Use of other screws will invalidate warranty and failure resulting from internal damage from the use of the screws.
If your incubator mounting has grommets this may mean that the supplied screws are too short however longer screws will make contact with wires internally which will short out or break them. You will need to create your own new bracket for mounting (they are not available for sale).
