simplicity 7117 question

Recommended Posts


Hi I have a simplicity 7117 had for about a year had the series 1 kt17, (blew a rod). didn't find out till after it blew how bad the engine was.I'm going to replace it with a 20hp kohler command, I know it will go in no problem, I just need to know how to wire it up?

Thank you Dan

First off, welcome aboard, Dan!

The Command is a great engine, and it will fit, however, to say it will "go in with no problem" isn't exactly correct. Consider that electrical, muffler and heat shield, driveshaft, mounting plate may / will be issues. If you could find another KT or Magnum engine, all or most of these issues go away. So unless you are just going to bite the bullet and buy new, this is something to consider. Just a thought.

You won`t need a engine mounting plate. Crankshaft height is the same as you have now. You will need to drill new holes in the frame. You will need a different drive shaft and the aluminium flywheel to drive shaft coupler part number 24 029 09-S.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
