K482S

Recommended Posts

Finally got up my courage to take the oil pan off of my K482S this afternoon. Good thing it was sunny out and warm in my shed.

Here is the engine sitting on the frame rails:

Here is the engine with the oil pan removed:

Closeup of crankcase. Things are looking pretty bad at this point.

Closeup of crankshaft. Looks pretty bad, but I am no expert. But from my limited past experience, this should be nice and shiny.

Piston rod debris sitting on top of oil pump screen. The screen was pretty gunked up as was the bottom of the oil pan.

Cylinder No.2 from inside the crankcase. You can already see that the piston skirt is broken.

Debris in the oil pan. I have it draining at the moment. No doubt there are a lot more pieces in there.

Pushed the piston out with a long screwdriver, and here it is:

This is a shot of crankshaft through cylinder No.2

I am amazed that this thing ran so well on one cylinder. Unless it just happened to break just before I shut it off. What would be the odds of that?

Suggestions, options? Anyone? Buhler?

Is it worth pulling the crankshaft out and having it remachined? What does something like that cost?

Do I have to take the flywheel off of the other side to get the crankshaft out (double-plus unfun)?

I have to go hunt down my boregage and let it sit in the house overnight to warm up. It's been sitting in my barn for probably a year. I'll try to take measurements tomorrow. Dunno if it's worth the bother or not. I really don't want to tear this down to the block and have it completely remachined (can't really afford it atm).

I might just have to put it back together and park this thing and wait for better times.

BTW, anyone know where I can get another K482 without having to pay through the nose?

Thanx in advance for all your input.

James I have the same problem with the new 18 auto that I just purchased (knew this before purchase)

I am sorry to hear that I have company in that regards. It's sad to see these motors bite the dust. Do you plan on rebuilding?

ya thats a drag,ive been where you are,(not a twin though)with a broken rod,measure every thing when you can,i just paid 150 for a single to be bored and crank turned,a agree with whats been said,put her aside till you can afford to do it right,its not gonna be cheap for a twin,but when redone right that would be a heck of a motor

The 482 is fully shrouded. Better look for a tin on that side that is missing one.

Thanx Bob, I asked around about that. The only response I got was from Jeff in PA. He didn't have a shroud on the No. 2 cylinder either. I kinda figured wheel horse left it out for some reason. I'm glad to know that for sure. Now I gotta find a shroud somewhere. At least I am not in any hurry - it'll be a long while before I get it running again.

one more

I think mine has the same rod broke

Looks pretty complete. Nice find. Do either of your D-series have an engine shroud on the right side cylinder? As Bob pointed out above, mine appears to be missing.

That piece of tin is listed as a part in any parts lookup on the net for the K482S. I wasn't sure if it should be there or not since Wheel Horse has been known to modify lots of parts for whatever reasons they have/had. Also, Jeff in PA has another 18HP D-series that doesn't have the particular piece of tin either. What gives - we are all missing the same piece? Strange, but not unheard of. I guess we all need to keep our eyes open and pick up one when possible.

James I have the shroud that covers the head on the right but no shroud that encompasses the cylinder jug like on the right side of the 482. I still cant find anyone to tell me if there shoud be a jug shroud on the other cylinder.

Yes there should be one I found mine today

might be parting this thing out

Thankyou for your input. It is odd that both Jeff and I should be missing the same identical part. Maybe they were known to fall off.

Sorry to hear that you are parting it out. I think Jeff could use it more than I since my engine is now officially a basket case. I'm not sure what I am going to do with it yet. Probably just button it up and put it in the back of the shed till I can find a reasonable machine shop in my area. I'd like to get this thing running again, but money is tight. Would really love to repower it, but the costs are way too high for that.

I'm really not looking forward to ripping out the crankshaft. The cylinders I can hone here, but I can't do a damn thing with the crank. Maybe one of these days I'll get a good lathe.

Here's a pic of the shrouds that are on my 482. This is from the Kohler Parts manual for the 482/582 Twins.....

1 and 2 are the bottom cylinder shrouds.....4 and 7 are the head shrouds......3 and 5 fit beside the governor and vacuum / fuel pump area.....5 and 10 are the flywheel shrouds. There are some other tins listed but must be for other applications.

Here is a set not sure what kinda shape

This may also be another one on ebay:

One of the useful features on ebay is the ability to save a search and then have them mail you with hits. I have several searches that keep my appraised of K482, D-180, and other wheel horse stuff. They usually send out an email once a day for each search if there is anything listed. Sorry to sound like I am hawking ebay, but it is a good source for some hard to find parts.

You can also search the internet for:

A-277130-10-S for the .010 under rod or;

A-277130-S for the standard rod.

OK, so I guess I am going to send this out to a machine shop. Anyone know of any reasonable machine shops in North NJ? How far should I tear this down before I hand it over. I'm guessing almost completely, but I just thought I'd ask.

What do you folks recommend having done beside the crank and the cylinders? How worried should I be about the valves and guides? Should I worry about the cam? Should I bother to replace the valves or lap the old valves and reinstall them?

I'm fishing for opinions folks. Feel free to add yours.

James

P.S. I know your offer still stands Paul, but you are just too far out of my locale. But it's good to know that there are still nice people around.

I have been taking my time tearing this motor down. Doing my best to label things so I know what goes where.

One of the issues that I am having is how to remove the pto assembly from the front of it. There is one center bolt that comes off easily.

Can any tell me if the pto is threaded on the shaft or should it just come straight off. Any help would be appreciated.

Thanx,

James

Out of the manual for the D-200.....

It is pretty straight forward....I think mine slid right off...

      I am looking for an engine that will easily swap into my C100 that is not the K241AS. Any suggestions?
    • By Sarge
      What started out as a simple task of moving my 6-1/2' x 12' utility trailer to unload it's contents back into the Shed Repair Project after building a new floor turned out to be a really bad day . I figured the weight of the trailer and it's load was probably around 2,500lbs or more and the big D-180 should be able to handle it . Used the 3pt hitch and an adapter to lift the trailer tongue and off I went...until I got to the end of the north drive and the pump coupling on the hydro failed - badly . In hindsight - the trailer probably weighed closer to 4,000lbs the way it felt behind the truck ...
       

       

       
      Now , the trailer had to be taken off the tractor and put on it's jack ....which didn't work out too well loaded that heavily . Since the trailer was built with 2x3 angle iron on the tongue it decided to fold itself into a pretzel - despite the wheels being blocked tight so it couldn't move . It fell over and I had to use the HI-Lift to get it off the ground . The sight of the trailer falling over in the rear view camera on the Dodge is still well embedded in my memory - I knew that was going to be another large project .
       
      The coupling had an earlier repair from last winter's failure - so a pto pin was driven through the hole to get it out back to my work area to be fixed later . It made the short trip , but just barely and the tow valve was frozen tightly . As it turned out , the damage to the D was a much bigger issue..and cost 3 times as much in total .
       
      The pic doesn't do the damage any justice - that entire tongue was bent badly -
       

       
      Sand blasted , new tongue built and waiting for paint -
       

       
      Painted , as it sits now awaiting the lights , wiring and re-install the floor decking .
       

       
       
       
      All the while - got more work done on the D's pump problem . Found a great used pump , as well as a spare coupling in good shape . After a lot of machine work ($$$) we came up with a solution and everything was back together...
       

       
      After all this I found that both the original mufflers were completely shot and falling apart - so another project ...
       
      Bought a pair of 180* mandrel bends , two cone transitions and a pair of @jimkemp 8" mufflers (very nice, btw) . Fabricated the flanges for the engine's exhaust ports , as well as the pipes for the stacks -
       

       

       

       
      Spent a lot of time rolling the engine over on the starter to slowly prime the pump back up and finally , after several months - fired Big Ugly to test the exhaust before painting the stacks . No leaks from the hydro thanks to some new o-rings and backer rings from @pfrederi on the hydro manifold , that was a big relief .
       
      A bit shocked at the sound of the big opposed twin - somewhat like a Harley running on the choke or something - but overall not obnoxious or too loud ....
       
      D180 startup.mp4
       
      If you don't want to wait for the MP4 to load - here's the YouTube link -
       
       
       
      I don't think the camera's microphone will show the sound too well , but so far I like it . Took a ride around the block , nice having this beast back up and running , finally . Now to finish that dumb trailer....pretty much wasted nearly the whole summer getting all of this done plus the hours at work . I'm about ready for a break but need to get ready for winter .

      Hi I am looking for a distributor drive gear for the Renault 800  on the d250.  Also a cylinder head. I lost the gear.
    • By Rob R
      Hi folks Brewster Rob here, was gifted a Cub Cadet LTX 1040 in great shape other then a completely blown 19HP in-famous Kohler Courage SV590, today I acquired a 17HP Pro OHV CV490S in perfect running condition.... so I want to swap the engines. They have identical vertical shafts question is the electrical. The Courage had four wires coming from the engine red/green/white/purple, the Pro has 3 white, 1blk and 1 red.  I also have the alternator and regulator from the blown Courage.... might I be able to swap alternators???  I of course have the old Courage key switch I do NOT have the new engine key switch.........  Need help from the Red Square wizards and PLEASE think about the best result way to go here.... thank you in advance.
