Jesse Rieber 28 #1 Posted April 8, 2021 I just purchased a Kohler engine to replace the 2 cylinder ONAN in my D160 Wheelhorse. Apparently that tractor used both the Onan and a Kohler 341 engine. So, I obtained a 341S Kohler (spec #71240a) serial number 9006651. I'm trying to determine the year of manufacture of this engine. I believe this will work and fit into the D160, at least according to one of the members who responded to a previous inquiry. Can you help me identify the year of manufacture?

Jesse Rieber 28 #3 Posted April 8, 2021 Thanks, got it. I actually realized I had downloaded the overhaul manual after I posted and found the id scheme. Thanks however for your kind response. Share this post Link to post Share on other sites
