682 engine swap

[msmucker]

I did a search but came up dry so I am looking for help putting a kohler M18S motor into a 1985 682 that previously had the kohler KT17.

The M18S looks ready to drop in place, however I had heard from a shop that there is a voltage difference between the two and was ready to sell a diode kit that changed the voltage to the correct one. Has anyone run into a voltage problem doing this swap? If so do you know what the swap needs?

The M18S motor that I have is also missing its starter and the old one from the KT17 looks like it might work, but I don't want to swap it before I am sure it wont screw something else up.

Any advice would be greatly appreciated.}

They use the same starter. Your shop is correct there is an electrical/voltage different. Look down in some of the earlier topics in this part of the forum and you'll see info on it from Steve Blunier. You have a few different options such as changing the ignition switch, putting in a relay etc... Your shop sounds like they know what to do.

Do you know how to adjust te brakes on a 682.

does your 682 have internal or external brakes. The owner's manual which is available online should show you for both of them.
