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?

If you arent set on a Honda, there are quite a few very nice Kohler kits around...

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.

Frank,
My dad and I built a 317 from a basket case last summer we put the 18hp honda engine kit from SEW. it was a great kit, the engine has lots of power and it RUMBLES! We took it to Bryan Sewards plowday last April and it never ran out of power. My suggestions would be:
1. if you don't have the tools to make a kit(like me) buy a 23hp briggs kit from Sew or buy a kohler kit from ?Pruitt engines.
2. you could build a kit like Andre did if you have the tools
3. You could send the tractor to a local small engine shop and have them build you a kit
4. You could send the tractor to your local Deere dealer and have them build you a kit
here are some pictures of it(there is also one in my profile)

Robert, do your side panels not fit anymore with the Honda?
As far as Kohlers and mufflers, the Kohler kit from Edens Ltd has it exit out the standard location, and you can fab a muffler, or have someone do it easy enough. There is a thread on here about a Kohler conversion, where the exhaust was modified to work, and its pretty simple and straightforward.

Frank,
Most of my own part list:
![]()
This muffler seem to be smaller than the original:

I don't have any drawing for the firewall.
This is how I took the measurement:
![]()
Then I transfer to a cardboard then I removed 3/8" all around.
Then I put 1" x 1" self adhesive foam inside the hood and the sides covers aligned with the firewall.
For the cooler support I removed some paint with a grinder with sandpaper to find the spot weld.
Then I drilled both the firewall and supports in the center of the spot weld.
I used the holes in the old firewall to mark their position to the new one.
Then I align the holes of the supports with those mark and fill the holes with weld.

Frank,
Your lucky, you have the opportunity to be the first one to try this new jewel:

With all the improvement they made, I feel like my old GX670 is already obsolete.

Andre,
I continue to find it amusing that the Japanese still get some translations a little off -- note "Cotton edge" styling in place of cutting edge...

It does look to be a good power plant for a repower though. Plenty of power and torque. Was the earlier series engine a hemi also?

Chuck - Good catch. It is quite obvious that something got lost in the translation. - Dave

I don't have any good picture of mine but the valves are side by side with no angle.
For the translation, I receive a list by E mail every week from a local magazine.
Belive me many translation to french made by small company are very funny.
