Kohler 321PT on my Raider 10?

Recommended Posts

I recently acquired a Kohler K321PT. I want to put it on my Raider 10 but it has a recoil starter. My question is can I put an electric start on this motor and will it bolt up to my Raider 10 to replace the Tecumseh hh100

:text-welcomeconfetti: to the :rs:Postal.      I'm afraid I don't have the answers you need, but hopefully someone will be here soon to help.


The 321PT    P =pump model and T=recoil start.    The crankshaft output size may be larger than the HH100 requiring a different drive pulley and PTO.

For electric start you may need a new flywheel to get a ring gear.  Also if you want a charging system .  If you want charging will also need a stator and regulator

:WRS:     Many pump engines have a tapered crank shaft on the output side. You will need to make a mounting plate or (presuming it is the big block) find an oil sump with mounting holes on the bottom like this one.5980f54004c2b_Jaysoilpan005.JPG.e30ed2b903800a6ad8b3ddee65a1511d.JPG

      @WHX14, @Achto, here's the offending culprits of Kohler K161 fuel tanks on the CC ORIGINAL, that keep breaking the solder around the fuel outlet bung, any tips on repair would be greatly appreciated, as well a couple pics of the original engines/tins and the tractor with few upgrades I'm planning with the repaint, besides the K181 with ring gear starter out of a Gravely, Jeff.

      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.

      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 .
