Is your Mark V motor not running or performing as it should? Add power to your older Mark V or bring your machine back to top performance.

How to tell if your motor should be replaced:

• Bogging or Lack of Power - If your motor seems to lack the power it once had or bogs down when cutting heavy boards, it's probably time for replacement.
• Fails to Start - If you have experienced this problem and have already replaced the switch with no starting success, it is definitely time to replace your motor
• Squeaking or Humming - Squeaking is a sign of bearing failure, while humming indicates that the motor is struggling to start. If the motor still squeaks or hums after removing the drive belt, it should be replaced immediately
• Smoking or Foul Odor - Either of these problems are an indication that the motor should be replaced as soon as possible

Two versions of the service motor are available:

• The 513964 version includes only the motor and requires that the old motor sheaves be removed, replaced, and new sheaves reinstalled to factory specifications a task that could be difficult for some customers.
• The 516152 version includes the two sheaves with key, spacer, compression spring, washer, and snap ring all assembled and properly adjusted by factory-trained professionals. With this assembled version, all vital components will be freshly replaced and will perform properly for many years to come.
