Service Advisory: Castle 14xx and 15xx Series Motors

It has come to our attention that a very limited number of 14xx series and 15xx series motors may have been assembled with Front End Bells that were not properly machined during manufacturing. Affected motors will have one or more of the three screws that attach the Front End Bell to the green motor body/can protruding above the top surface. The protruding screw(s) will cause improper alignment of the motor (and the customer-installed pinion gear) once it has been installed onto the vehicle. This misalignment could result in damage to the vehicle’s spur gear or the motor’s pinion gear.

Customers who purchased a Castle 14xx or 15xx series motor AFTER JULY 1, 2014 are encouraged to closely examine the Front End Bell of their motor. If the head of the machine screw extends above the plane of the Front End Bell (illustrations above), you are asked to contact Castle Creations Customer Service Team via email ( or call 913-390-6939 between the hours of 9 AM and 5 PM CST, Monday through Friday. A Castle Customer Service Representative will discuss corrective measures with you personally.
