http://www.simplicitytechpubs.com/6767PRINT/PDF_files/TP_400_1355_00_AT_S.pdf I presume you are talking about spring # 46 part # 159159 on the belt tightener? Does the spring have good tension on it? Does the belt have flat/wear spots on it causing the idler to jump? Have you tried closing up the eye clips on both ends of the spring?

I can't get a picture from the manual, but the one maynard has listed it is part # 46 in the first picture with the drive belts. Sorry Maynard I did not read all you said; yes the end of the spring is crimped good I can pry the tensioner pulley over enough to make the spring not have much pull on it, might need a new belt in there. all thought the belt looks good. OOPs today I tried it again and lost the spring will need to look for it.:O

      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
