So I called SEW today to inquire about a 24HP Honda conversion for a 318. They tell me they no longer sell that kit. So can anyone here tell me what needs to be made and supply some sketches? The mount looks easy. I know there is a plate for the front and a bushing. Then the piece for the drive shaft, and the muffler and heat shield + wiring. Anything else? Anyone know the source of the basic muffler they used?

Frank,

I put a Honda 24 in my 318 without buying a kit.

I have CAD drawing for the clutch adaptor plate & bushing:

For the muffler I used an original muffler from Honda with a lot of modifications also to the front grill support and the sides covers:

For the drive shaft I bought an adaptor from Honda with a yoke from my JD dealer:

I made a new firewall plate, air tight without the isolation foam:

I don't have any wire for the throttle, I used small ball joint, linkage and bushing:

For the choke, it's the 318 original with a custom bracket and anti freeze improvement.
I didn't made adaptor plates, the motor is bolted directly on the plate like the Onan.
I have CAD drawing for the electric connections.

If you'r ready to spend few weeks instead of few hours for your repower, let me know I have a lot of information to share.

Andrew, any chance I can get the cad drawing on the electrical hookups from the John Deere 318 with the Honda GX670? Email [email protected]
