Common questions about this unit
How do I confirm this is the right motor?
Match the number on the unit you are replacing against the cross reference list on this page, and check the mounting and shaft against your old one. For these motors the part number is far more reliable than the machine model, because the same machine is often built with more than one motor over its production run.
Is this new or remanufactured?
New. Every unit we list is a new unit, not a rebuilt core, and it carries a one year warranty. There is no core to return and no deposit to chase.
How fast does it ship?
Orders leave within three business days. Ships from USA. You can read the full terms in our shipping policy, and returns are covered in the return and refund policy.
What if I order the wrong part?
Returns are accepted within the window set out in our return and refund policy,and a restocking fee applies unless the part is defective or we made the error. A unit that has been installed or used cannot be returned, so it is worth confirming fitment by part number before you fit it.
