By 12 hp Kohler
For sale is a kohler magnum 8. The engine came out of an 308 eight speed. I haven’t tested the engine and suspect it need some work to run. The P.O. said the fuel tank leaks at the grommet but I’m not sure. The engine is as is because it is missing a few things and has not been tested. The engine isn’t locked up it turns free. PM me or email with any questions I will try to get back to you as soon as possible. The only thing the engine appears to be missing is the air cleaner assembly but there may be more as I have not done much work on the magnum series kohler.
This is my first post. Several years ago I bought a c120 auto and have used it to mow and snowplow with great success. The other night in the midst of a snow storm I was in a hurry to get going, and didn't check the oil and didn't give the engine enough time to warm up. Result seems to be a broken connecting rod, since it cranks now much faster than it did before and won't start when it was a terrific starter before.
So I'm looking for ways to repair the damage I've done. I really love the tractor, comparing it to modern ones that feel like tin foil convinces me that I want to fix this iron horse.
I am in southwest Michigan, and looking for help.
thanks in advance.
Went out in the middle of the week, temperatures in the teens, tried to start my C145 plow machine.......no go!
Seems like the ACR is stuck, backfires through the carburetor. Using 10w-30 oil.
The machine always started pretty good. I was thinking I may need a block heater.
Anyone using the heaters? If so what type? wattage etc.
I see pad style, drain plug styles.
I was cleaning some oil residue from an earlier dumb move - I try to keep things clean so any leaks that spring up show easily . I noticed along the top of the block towards the center from the right cylinder's valve cover a cast marking , cleaned it off and found this -
The casting mark clearly shows K532 .
Now , is this a case like the single cylinder blocks that were stamped "301" but you had to check internally whether it was a 10hp or 12hp engine ? K241 & K301 blocks are stamped the same and that is common knowledge .
But , what about the K482/K532/K662 twin opposed cast iron engines , same deal ?? Any insight on the blocks or anyone know for sure ?
Or - did someone swap out the original K482 from this '74 D180 to a K532 20hp from a donor ?? Some of the tins seem to be completely black to the bare metal , while others are clearly red underneath the black - so some painting has been done and this tractor it has at best a sketchy history . At one time it lived at the welding shop next to me to the West , or at least for a short time . The folks I got it from are about 40 miles away in a rural area and the gal that sold it had told me her father had gotten it from the town where I live - from the local welder . His son that now owns/runs the shop doesn't remember it but it may have belonged to his Dad who started the business - but he does say he knows his Dad never bought a new Wheel Horse , he'd only owned a Cub or two that he remembered . Anyway , hard telling on it's history and a lot of mods/repairs have been done in the machine's lifetime .
I'm just curious if this is the original engine/block - the tins are marked as a K482 / spec 35222b as it should be to match the '74 model year in the published model year reference list . The model tag was long gone off the tractor when I got it , the year came from figuring out the sum of it's parts as to the model and such . Maybe that casting mark explains why this engine feels so strong , there is a noticeable difference between the 482 and 532 engines before from when we used them in other industrial equipment such as Ditch Witch , ect . The 20hp version just had a lot more torque and grunt compared to the 18hp . The K662 is insanely powerful and quite underrated - I ran one of those years ago on a compactor with a gear drive transport feature - that engine is a whole different animal compared to the 18 & 20 versions .
