MikeES Posted January 2, 2019 Posted January 2, 2019 (edited) I did not know that this engine ever existed. Magnum 17? https://www.ebay.com/itm/Used-Kohler-M17-Magnum-17-Engine-1-Crank-from-Cub-1730/401558499587?hash=item5d7ec07103:g:cusAAOSw1qtbMmC~:rk:1:pf:1 Vertical shaft engine. Does not show up on Kohler's web site. (Later became the MV18?) Edited January 2, 2019 by MikeES
PhanDad Posted January 2, 2019 Posted January 2, 2019 Down-rated MV18 special for Cub? Like the 14 & 15 HP Briggs cast iron singles were.
GregB Posted January 2, 2019 Posted January 2, 2019 The gentleman I bought a M18 from to re-ring, had it to put into his Gravely after re-ringing. He told me the only difference between the M18, and the 16hp version Gravely used was only the Governed speed. 1
Brettw Posted January 3, 2019 Posted January 3, 2019 For what it's worth, as a vertical I believe it should have an MV model designation to it, as would the M18 / MV18. That being said, Kohler's site is great for owners and service manuals, and there are neither for a M17 or MV17. I believe it may have been a proprietary designation for CUB, for whatever reason. Those are the only Magnums I have seen with a 17 rating; CUB vertical engines. I don't think there is an actual Magnum 17 horse engine. JMHO
LMichaels Posted January 3, 2019 Posted January 3, 2019 FWIW the photo shows a horizontal shaft engine not a vertical
PhanDad Posted January 3, 2019 Posted January 3, 2019 4 minutes ago, LMichaels said: FWIW the photo shows a horizontal shaft engine not a vertical That's what I thought at first also. But it's a vertical; check the position of the dipstick - if it were horizontal, they're be oil everywhere. 1
GregB Posted January 3, 2019 Posted January 3, 2019 Some years of the production run, the blocks were the same, it is possible to make a vertical into a horizontal. Someone here did it pretty sure. have to change intake, oil pump pickup, dipstick etc. 1
MikeES Posted January 5, 2019 Author Posted January 5, 2019 I think it was born a vertical, look at the decals on the head tins. That pipe sticking out of the sump/closure plate must be the oil drain??
Brettw Posted January 5, 2019 Posted January 5, 2019 (edited) In my most humble opinion, this is not a converted engine and was a vertical from the git-go. The decals on the tins, the oil fill, the mounting plate at the crank (which is entirely different from a horizontal "closing plate"), and again, the 17 HP designation that I have only seen on verticals for a CUB. I am not saying that simply because I have only seen the 17 on a CUB vertical that that's the only 17 Magnum ever built, but that's the only place I have seen them. That and the fact that there isn't any Kohler manual for a 17 horsepower Magnum all leads me to believe this was a proprietary engine for CUB. Or, I could be completely wrong. It has happened before. Once I think. When I was 5. Or was is it 6?................... Edited January 6, 2019 by Brettw 3
Chris727 Posted January 5, 2019 Posted January 5, 2019 Brett is correct. The Cub 1730 is a vertical shaft tractor. I have the 917H with the converted engine. I bought it from Darin Butcher (Country) who originally did the conversion.
GregB Posted January 5, 2019 Posted January 5, 2019 Nice to know I can still remember some things. Unlike where I left that special wrench, or what I was supposed to get at the grocery store 1 2
