7119 hydrostatic

Recommended Posts

I just bought a 7119 hydro and was going to drain the
hydrostatic transmission then refill and add a new filter.
I talked to my simplicity dealer and he advised me not to
do this because air pockets get into the system and takes
a long time to work out and the tranny gets noisy. he said to
take the new filter fill with fluid then take off the old clean the
area with a cloth and put the new filter on, then top off the fluid level.

does this make sense?

Tom, What kind of "dealer" told you that! That's nonsense!! Drain trans and remove oil filt. As your looking at the trans from behind, just above left axle you'll see a small pipe elbow with a bleeder valve on top. Remove bleeder-it's a 7/16" nut looking thing. Refill trans from the tube you see in the rear of the trans.Prob. need a small funnel,replace oil filt,Fill tube right up to the top,put bleeder valve back in and cap on fill plug, run trac.around,check fluid level,should be 1/2 way up tube,check for leaks and your in business!Ford type F auto trans. fluid is what I use,although you can use the Sim. hydro fluid of course.The reason you would get any noise is because there's air trapped in sys.By removing and reinstalling bleeder you get rid of trapped air. Good Luck! dlc

      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
