857 and CH270 Kohler

Recommended Posts

Bach-Ed

My 857 had a K271 that had been installed by the PO.  The engine threw the rod and damaged the cylinder.  I was able to get a new Kohler CH270 for a replacement.  I didn't feel at all bad about this as the K271 wasn't original anyway.  Here is the problem,  the existing holes don't come anywhere close to matchcing up.  If all else fails I will make an adapter plate but I figured I had better ask if there is an easier solution, like a premade adapter of some kind?

The holes are 79.99mm (3.149") apart in the width and in the fore/aft they are 162.00mm (6.378")

I guess I should add this: If I end up making an adapter plate,do you have any suggestions of what (or what not) to do?

Wheel Horse never used a CH270 so I think you are are your own. 

 

You need to get the crankshaft located in the same position as the original engine or you will have a lot of work to get the correct belt length and belt guard to function correctly for clutch action.

I've done this conversion several times with the 212cc predator engine witch is basically what you have just a fancy version but the mounting holes should be the same I always use a adapter plate from a wheel horse b-80 or b-60 the give you plenty of room to work with then I set the motor and plate on the frame and put the belt guard on and make sure the motor is lined up with the belt and belt guard I check everything twice and then check again then mark all ur holes and get to drilling I've always been able to use the same drive belt because buy using the mounting plate and belt guard your the motor is in the same place its will set just a tad taller than factory that's why the belt that powers the deck will need to be about an 1/2 inch longer

      I needed to disassemble the brake/cluch linkage on my 857.   Am I missing something or do 2593 Clutch Rod, 5544 Parking Brake Lever and 3935 Brake Rod all need to be in place on 4899 Clutch Rod Pivot Arm  before I can struggle to align the holes with that of the 3950 Idler Arm Shaft to insert the roll pin?  I'm using up all my naughty words trying to get this back in place.  I'm hope someone can suggest a better way.  Or all you can do is extend your sympathies?

      Sadly Dan @Achto informed me the the other day of a 857 and a C-120 that was deposited at his local county dump. Dump rules are  such that once it hits the ground it stays due to junkyard dogs going to fisticuffs over scrap steel. Understandable  Despite some hastily made plans of bribery,  chicanery and/or hook or crook to rescue them we failed miserably. We may get drummed out of the Mafia for that one.
      I'll let Dan fill you in on the details if he has the stomach.  I would like to believe that that our beloved  ones would be smelted down to produce more tractors but then I wake up from that dream. Sorry no bone yard pics not that we would want to see them.
      Dan asked me if he had a problem over grieving over these lost gems. You decide... So in memoriam I feel it is quite nescessary to post pics of our lost loved ones. Since I don't have a C-120 here's what I have of a 857.  Please post your pics of either models. True story, I wouldn't hose you guys and not just fishin  for

      Sold all three to one guy today..
      Sad to see them go, but...
      One of the reasons I’m selling is because I’m thinning my personal collection down to custom, modified only. So,  I’m selling all my “stock” tractors. 
      Ilk still have a few “flip tractors”, but hope to get down to about 4 I’m my personal collection.
      We’ve been up around a dozen for a year now.. too much to keep up with..
        I think these are going to a good home.
