Is Mule 610 Motor rotation CW or CCW?

dtd24 · 10-20-2009, 12:11 PM

My first post, but I've been reading for a while.

Does anyone know what the engine rotation is for a 2006 mule 610 FJ400D-A50 motor?

I'm thinking about putting one in my 93 carryall. If it's not CCW then I'll just wait for a big block kit when I can afford it.

You should be able to find the answer if you google the specs on the motor and or the mule?

So It looks like this engine belongs to newer family of Kawasaki CW engines

It is not gonna work with your pre 1997 transaxle

Now, I called a Kawasaki dealer and he said that the engine rotates forward from the driver’s side. Wouldn't that be opposite from what the information you provided says?

To totally confuse, doesn't the info in your post say its CCW rotation?

Scottyb, I really appreciate your reply.

I thought I was great at searching but I could not seem to find that information

A lot of confusion on engine rotation? Harbor freight engines run clockwise when looking at the flywheel! If you look at the engine from the clutch side it turns CCW? So in doing an engine swap if the secondary pully is on the passenger side and the engine is mounted on the drivers side it is turning the secondary pully CCW?

PTO side is the clutch side, and that is the side the matters for rotation. So if it's spinning "forward" looking at the drivers side (which is the clutch side on the mule), then it's a counter clockwise rotation engine.

By far the majority of small equipment 1 and 2 cylinder engines are counter-clockwise rotation. Pretty sure Kawasaki only did Club Car a favor (because CC wanted to be special) making a clockwise rotation engine because I have never seen that in ANY other engine for small equipment.

I have used Mule engines in several carts including a V twin from a 2010 mule. All CCW.
