K361 Part

Recommended Posts


I have finally figured the problem on the k 361 was the wrong type of coil.  Now I am on the oil leak.  I have been told from the previous owner that worked on it saying that the rocker arm plate under the valve cover is cracked.  I have looked in a garden tractor salvage yard and was unsuccessful.  I'm scared to take the piece off without a replacement.  I was wondering if the piece was taken to a machine shop if it could be machined to spec from the original or welded?  Number 9 in this picture is what I'm after.

If it's broke it's broke. Taking it off carefully won't usually make it "more" broke. It won't weld well, cast aluminum, especially that's been exposed to oil for so long will have so many impurities that trying to weld it will look like a rooster took a dump on it, literally. Knowing where it is broken would be helpful. Around mounting holes? Between valve guide or push rod tubesholes? Rocker shaft mounting boss? If it's a non-structural crack that is just leaking oil I'd think about surface/crack prep & high temp epoxy. There are some low temp "aluminum solder" products that might work for a non-structural crack. We'd need a pic. to be more help. My guess since you're battling an oil leak is that the rocker plate mounting bolts were over tightened and it is cracked (if really cracked) around or near the valve guide holes. The only thing that is structurally important is the rocker shaft mounting boss. If that's good and there aren't any cracks from a mounting bolt to the shaft mounting boss then all the rest of it really does is just hold oil in.

      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
