A/C 620 gears inside the transaxle

Recommended Posts

This is my first time , so I hope I'm doing this right. I have a 1974 A/C 620. It is currently powered by a 22 HP Kohler Command engine. Recently while replacing the axle seals I decided to look at the gears inside the transaxle. Herein lies the problem; the 23 tooth gear which meshes with the double (lo-2nd) gear is rather badly chipped, worse than any other gear in the transaxle. Plus I found a fair sized flake of a tooth on the trans filter when I removed it, and I'm told the sunstrund hydro pump doesn't like dirt, let alone bits of gear tooth. No teeth stripped yet, just chipped on the edge where I've ground it too much over the years. The part # is 170825, and it goes on the input shaft. I can't get it thru any A/C or Simplicity dealer nor thru Briggs & Stratton. I'm really needing to use my #1 garden tractor. Of course I use 2nd gear more than either lo or hi. HELP!!!!!!!

Welcome Mark, You definitely don't want metal floating around inside anything to do with your hydrostat. The thing to do is to list your needed parts in our classified section or see if you can find it salvaged through one of our fine sponsors who do such salvage work.

      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
