Common questions about this unit
What voltage is this unit?
This one is 12. Voltage has to match your machine exactly. A 12V unit on a 24V system will be damaged, and a 24V unit on a 12V system will crank slowly or not at all. If you are unsure, check the battery setup: two 12V batteries wired in series usually means a 24V system.
What is the 66-102 number?
66-102 is the Lester number. Lester is the long standing industry catalogue for rotating electrical, and its numbers are how the trade identifies a unit regardless of who sold it. We use it as our part number because it is the one identifier that stays stable across every brand that has ever boxed 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 where a part carries a core charge, it is refunded when your old unit comes back within 30 days.
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.
