857 and CH270 Kohler

[Bach-Ed 170]

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
