jellyghost 378 #1 Posted August 22, 2018 I looked at two dark blue K-series engines today. I don't think they were original to the garden tractors there were on. One was built in 1987, but I can't figure out the date to the other because I can't find the serial number. The tag has the HP = 12, the Model No. = K301S and the Spec. No. = 47688. There doesn't appear to be a tag with the serial number. What does the dark blue color mean? How do I date the 12hp engine without a serial number or how do I find the serial number?

JAinVA 4,617 #2 Posted August 22, 2018 (edited) When you say dark blue is it like a Ford tractor blue or does it have a more greenish tone.If a Ford blue then maybe off a Ford gt.If more greenish then I believe it is the Kohler preference for factory color.I have a k341 that was on some industrial machine and it is painted Kohler blue-green.

jellyghost 378 #3 Posted August 22, 2018 (edited) It's more a blue-green, but I would have called it a "midnight blue" based on Crayola colors. They are definitely not a Ford blue. If it's the factory color, does that mean it was probably sold as just an engine/replacement engine? Edited August 22, 2018 by jellyghost Share this post Link to post Share on other sites
WHNJ701 4,162 #4 Posted August 22, 2018 I have several k engines that used this dark metallic blue/green,, I think if you bought just an engine it came that color from the factory 2 Share this post Link to post Share on other sites

This many years out I would say that what you have is a replacement engine.It could have come from someone who stocked Kohler engines or was taken from just about anything.The k341 I have is a great engine but was set up to run at a constant speed.I am in the process of adding throttle control.Kohler engines were a popular engine and could be found on all kinds of equipment.

pacer 3,159 #6 Posted August 22, 2018 I bought a D160 with a K341 that had a blue color and the guy said that he had replaced and it that was the way it came when he bought it. Kinda backed up by the tractor being a 1974 model and the Kohler tag showing its a 1994 model. 1 Share this post Link to post Share on other sites
ztnoo 2,297 #7 Posted August 22, 2018 I have a blueish K341 on my GT 14. The original K321 ate a rod and punched a hole in the block, necessitating a repower. It was my understanding when I had it replaced, it was a new, off-the-shelf, replacement engine which could have been used to replace a large displacement K series engine in many different applications. 1 Share this post Link to post Share on other sites
artfull dodger 329 #8 Posted August 24, 2018 (edited) I have a ride on scale train in my back yard, the little switcher engine we have has a K91T that came new from Kohler in that color.
