Docwheelhorse 2,561 #1 Posted April 9, 2012 Hello All, I was working on a Kohler Magnum 10 and noticed just above the drive pulley that cast into the block was K301???? Well everything on the Magnum says its a 10 and that would make it a K241.... SO is this block capable of being bored out to a 12 hp standard bore or is it just a fluke that ended up on the block?

rmaynard 14,945 #2 Posted April 9, 2012 Many of the K241's were made from the same casting as the K301 and had that mark. Any yes, they could be bored larger. Didn't know any Magnums shared that block. Share this post Link to post Share on other sites
oldredrider 2,547 #3 Posted April 9, 2012 The Kohler web site doesn't even list a Magnum 10...Perhaps what you really have is a K series engine in disguise! Share this post Link to post Share on other sites
JC 1965 1,528 #4 Posted April 9, 2012 Wow ! That's good to know, I had no idea that Kohler used the same block on those two engines. Share this post Link to post Share on other sites

Docwheelhorse 2,561 #6 Posted April 10, 2012 when doing a rebuild the guts are exactly the same other than the gasket set Well.... besides gaskets you need a different piston....right??? I assume the stroke is the same so the crank and rod drop in. Share this post Link to post Share on other sites
Docwheelhorse 2,561 #7 Posted April 10, 2012 There are TONS of Magnum 10's out there.... Alot of the 310-8 machines are magnums.... don't know what the kohler site is up to? Share this post Link to post Share on other sites

can whlvr 991 #10 Posted April 10, 2012 when i deal with the parts guy for rebuilding them he told me that they are all the same,thats pistons,rings,rods,and even gaskets except for the cam cover and the points which magnums dont have Share this post Link to post Share on other sites
oldredrider 2,547 #11 Posted April 10, 2012 I know Tony is right...there are plenty of "10hp magnums" out there...I seen 'em!! This is the link to Kohler's site I was referring to: http://www.kohlerengines.com/onlinecatalog/productMatrix.htm Maybe there were "tons" of 10hp K series left over and they morphed into Magnums?! As has been mentioned, the only "real" difference between the K series and the magnum is electronic ignition, starter mounting, sheet metal and color. All the guts are the same.
