Ark 600 pump seal

Recommended Posts

CTD01

The pump seal started leaking on my ark 600 loader with the Cessna pump. I crossed the original seal number to a National 472705. Specs on the seal are: .0562 I.D., 1.000 O.D. and, .0250 width.

I use the Timken 472705 without any issues as well.

HA! I see that it's the same number LOL!!!

That's always a good sign that you got the right number. dOd

      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
