Noisy Kohler

Recommended Posts

I just got a tractor with a 12 horse Kohler. It had a really disturbing (to me) noise low down when running. Not at all rpms though. Being sure in my mind it was about to blow I took it apart. Everything looks good to my eye, as far as rod and piston and crank. It has has been bored .10 over. The balance gears are really loose on their mountings.Can this make an (engine about to come apart) noise? I know some say to toss them and I probably will. Thanks, Jim

Hello, the balance gears can make a nasty noise, if they get loose i usually remove them as you need to tear apart the whole engine to replace the bearings.

the timing needs to be set, and the famouse kohler chatter will go away. its a must do, unless you want to slowly cook ruin your motor.... just my 2 cents.......

Yes, it is the only normal way I have heard of. Smaller gap=retard, larger gap=advance.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
