Fredo 56 #1 Posted December 7, 2021 I have the opportunity to buy a Kohler magnum 16. Few questions are they better than k series kohlers what are the differences and whats a good price to pay for a running non smoking one these days? Share this post Link to post Share on other sites
8ntruck 7,368 #2 Posted December 7, 2021 Not sure on the current price. If you can get the spec number for that engine, it will lead you to what the build options are. Should reveal things like output shaft diameter and length, the presence of a thrust bearing on the crank, type of ignition, alternator output, etc. 2 Share this post Link to post Share on other sites
roadapples 6,983 #3 Posted December 7, 2021 No points to mess with. In good condition probably start at about $400 ... 1 Share this post Link to post Share on other sites

It be hard to get a spec number since its about an hour away from me an its hard to move around for the old gentleman that is selling it. Share this post Link to post Share on other sites

The cranks were supported with large ball bearings on both sides. Thrust bearings were used on later Command engines because they had no ball bearings on the crank and can't support an axial load. And all Magnums used a form of magneto ignition. Edited December 7, 2021 by kpinnc Share this post Link to post Share on other sites

Just trying figure if i should get the magnum 16 or if a 1974 sears ss16 with the onan 16hp(same price same guy, except the onan is non running, gas problems) would be a better option for a mud mower. Have heard it can get expensive to fix these onan motors. Share this post Link to post Share on other sites

kpinnc 13,667 #12 Posted December 7, 2021 For a mud mower, the stub shaft won't be an issue. But 16hp on one is overkill when linked to these WH transmissions, and probably the only difference between it and a K241 would be that you'll have half the range for given fuel capacity. 2 Share this post Link to post Share on other sites

I often get confused during conversations about Kohler M series engines. There are both single, and twin cylinder Magnums. I have a Magnum 16 Twin. It does not have ball bearings. 11 hours ago, Fredo said: Well it has a little snubby output shaft. Have you seen this motor? A complete model #, and spec #, would really tell a lot. Snubby output shaft, makes me wonder if it is tapered, for a generator. Horizontal shaft? 10 hours ago, Fredo said: mud mower Just what is a mud mower? I have a John Deere 165 I call my "mud mower" simply because I use it to mow a very wet area. Sometimes, standing water.

pfrederi 18,314 #15 Posted December 7, 2021 (edited) Stubby crank likely sign it was for a generator. Probably tapered also. I have seen adapters on EBAY to make it a straight shaft. If it is a twin M16 generator engine it will not have a thrust bearing... but if you are not using a PTO that is not an issue. The Magnum Twins have a full pressure lubrication system which would be better for your off roading than a splash system Edited December 7, 2021 by pfrederi 1 Share this post Link to post Share on other sites

Fredo 56 #18 Posted December 7, 2021 I just asked guy to see what the engine came out of. I want to say he did say it came out of a generator. I will confirm because if thats the case i will probably pass on it. Share this post Link to post Share on other sites
