valve spring question

Recommended Posts

finally putting the 23D back together. the valve springs seem to be slightly different in strength. the book says the heavier spring should be the exhaust spring. the springs have a cup at the top, which is the same for both intake and exhaust. but the seat at the other end is different. one is set up to rotate the valve. which valve gets the rotator seat, intake or exhaust? first parts to go in and already i'm having problems. hope it isn't all going to be like this.

thought i would be able to pry the springs enough to get the little keepers onto the stems WRONG! none of the valve spring compressors at the local parts store (advanced auto) were the right type so i bought a $6 door panel removing tool that looked like it would do the trick. WRONG again! an hour to get the intake in and my finger tips banged up. went to Sears, the next town over. they had the big 'c' clamp style compressor for $20. had to have 'she who must be obeyed' help hold the compressor but it only took 5 minutes. by then it was beer;30 so tomorrow i will continue

      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

      I assume it's a bosche, correct
