Adjusting Valve Clearance

Recommended Posts

stevenj
I've got a Kohler Magnum 20. I was checking the valve clearance and it is a little tight. The manual says that you have to grind the ends of the valve stems to adjust the clearance. Question - What do you use to grind the valve stems that gets them smooth and square?

Cheap method would be to jury rig a vee block perpendicular to the side of a grinding wheel. Lay the valve stem in the vee and hand feed it into the side of the wheel while rotating the valve. A machine shop would use a Spindex on a grinding machine. I have gotten away with doing it by hand on the face of the grinding wheel but am sure the end was not "square". Others may have better methods. Whatever method used be careful and go slow. It is real easy to remove too much and have excess valve clearance.

I just use a regular flat file. I put it between the end of the valve and the follower. Move it back and forth till the clearance is correct. This is what I have done on B/S engines. I don't know if you can get the file into the valve on the Kohler Magnum engines.

      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 
      Paul
