My 75 C-160 with a sundstrand 90-1140 hydro was getting weak, so I put in a sundstrand 90-2046 from my 72 charger 12 parts tractor. Everything fit up and it works fine.
My question is can the hydraulic lift cyl be used on the 90-2046, and if so ,where do the two lines connect on the 2046 ??
Thanks for any help.

I know that they can be converted but I am not sure exactly how. Since the old one is bad anyways maybe do some exploratory surgery and part swaping

Thanks for the reply. I will eventually open the 1140 and look for problems. Hopefully rebuild and reinstall. I am leery of opening the 2046 as it is working and seems strong.

The pump and axle are so much different , I just don,t have a clue witch might be the correct ports for the lift on the2046.

If I can"t get positive assurance where to connect hoses, I"ll probably remove the hyd lift and put on the manual lift.

Based on your sunstrand #s it appears you replaced a piston to piston unit with a hydrogear unit. You can use a hydro lift with the older hydro gear unit...if it has (or you can get) an implement relief valve ( Spring 7753 valve 7754)...they are not the same valve and spring used on the piston to piston unit you are replacing.

Here are some pics of the two units.

The two ports where I removed the hoses from the weak 90-1140 did not have springs or valves in the ports.

The two ports on the side of the 90-2046 where I think the lift hoses should be connected have a spring and probably a valve under the plugs. I have not tried to remove the valves . Any more help is appreciated.

By the way.... the spring and cone # 6631 and 6632 cross to new parts. Took me a while to track this down when I was looking three years ago.

Current (as of 3 years ago) Sundstrand part numbers are:

3102027 - spring

3100053 - cone

Check at any local hydraulic shop that services Sundstrand equipment.

I've still never installed the kit. The tractor it's going on is still in boxes on the shelf.

That was what I needed. Thanks a bunch Super Mod.

My guess were the hoses connect ( on the side) was totally wrong.

It's clear were the new spring and cone go and were the long hose connects at the rear in the tool box. I can't tell if this is the pressure or return hose or if it matters.

The other hose , the short one connects on the top, but there are two ports there and I can't tell from fig 5 if it gos to the front or rear port.

Got my answer at the show yesterday. The short hose goes to the rear top port.

Picked up a new gas tank for the C-160. Great day. Thanks to all.

I'm replacing my stock lift control valve with a control valve equipped with pressure relief, on a Charger 12 tractor. Can anyrone tell me which line

on the Sunstrand hydro is the pressure line and which is the return line. I suspect the correct connection is important due to the pressure relief feature.

 

Thanks

      I was pulling a roller and thatch rake the other day with my c120 hydro and noticed oil on the back of the fender. On looking closer I saw the plug thing on the back of the pump leaking oil. Any advice on how serious this will be to repair? Anything helps

      So yesterday I picked-up a C175. She was rusting away as she was stored outside. She had a new to her Kohler K341. @squonk The previous owner indeed better had"LET AN ELECTRICIAN      CHECK his  SHORTS!"  as bad wiring shorted the battery out, and exploded/melted. She has a Sundstrand hydro pump with a Filter, is that normal? By the pump I believe it's a 1980. But you never now for sure as it's made in Oevel. Due to the bad wiring, the engine was in no running condition. But don't think the K341 has many hours on it. The hydro I don't know if it works. She was hard to push. So i lift up one wheel, so we could roll here one one wheel and the diff prevented the trans from locking up.
      So first things to do:
      1) get the engine running
      2) replace the steering wheel, but don't think removing it will be very hard as it's already split in two.
      3) replace the axleseals, the oil leak caused a lot of sandbuild up as she was mainly used on for leveling out a horse track.
      4) clean all the acid and remove all the old wiring to do a full rewiring
      5) replace the plastic seat pan with a metal.
      6)...
       
      I'm looking forward on my first C. 
      It's also my first hydro, I don't know a lot about them and prefer actual gears. Simpler and need less maintenance (parts-shortage). 
      But since I couldn't find another project WH and me hearing a lot of good things about hydro's  on the forum..  I finally took the shot.

      I have developed a kit that allows a Wheel Horse / Toro hydrostatic tractor to be operated by a pedal on the right side of the tractor. The original forward/reverse lever can be retained or removed. The kit includes everything needed to install the pedal kit and installation is simple with the help of a downloadable installation manual. Additionally, only one (1) 1/4" hole will need to be drilled which can be done by a hand drill. No other drilling or cutting will be necessary. Any tractor with this kit can be converted back to stock without any visible evidence that kit was installed. However, you'll never want to do that

      The kit operates very simply and similar to modern tractors. When the pedal is pushed forwards the tractor will move forwards. When the reverse pedal is pressed downwards, the tractor will moved in reverse. If the operator takes his foot of the pedal at any time, the pedal will automatically center itself and the hydrostatic transmission will return to neutral (stop). This enables the operator to use both hands on the steering wheel or one hand on the wheel and the other operating an attachment like a snow blower, plow, etc.

      The foot pedal is custom cast in Aluminum, uses brass bushings to minimize wear, and it closely matches the OEM Wheel Horse BRAKE pedal commonly found on 8-speed manual transmission tractors. Modifications were done to the pedal to add the reverse pedal and adapt the pedal to the rest of the kit. For the most part, the pedal looks like it was designed and manufactured by Wheel Horse / Toro. Additionally, a grease fitting has been adapted to the pedal to further minimize wear and tear and if the brass bushings ever wear out they are fully replaceable without having to buy a whole new pedal. 

      The pedal kit fits the following series tractors with Eaton hydrostatic transmissions: C-1X5, 300, 400, 500. 
       
      My kit can be adapted to older hydrostatic tractors with the Sundstrand transmission, however, you will need to find an updated hydro cam commonly found on ebay. Message me for more information. 
       
      Here is a link where you can download the installation manual: CLICK HERE
       
      I am selling these kits for $330 shipped to anywhere in the United States. I offer multi order discounts as well. I will also sell to other countries for additional shipping charges to be determined.
       
      If anyone has any questions please feel free to PM me or post your question here and I will be glad to help. Or you can email me at mattdarling02@hotmail.com.

      Thanks!
       
       
      Below are pictures of the complete kit and the pedal installed on the tractor. Some modifications have been made since these pictures were taken. For example, the reverse pedal is now cast in aluminum instead of the steel pedal shown below.

      Hello, 
       
      I am hoping someone can help my. I recently acquired a c160 for the engine for another tractor. So I did a motor swap and wanted to see what the hydro was like. I put a plow on it C-160 (which now has a 12hp engine on it). I did a quick test run and everything was good. I drained the fluid and change the filter (Napa 1410 filter and sae 30 transmission fluid as it stated to only use this fluid on the tractor.) everything was working great after the fluid change. I plowed two driveways and the sidewalks near my house... all the sudden the tractor would not go forwards or in reverse. I tried to pick the plow up and nothing... I checked my drive belt it was turning like it should. I started to push the tractor and the rear was engaged so it would not move. Of course I was 400’ from my driveway and the plow was down which made it fun. I put the tractor in forward and started to push it and the thing took off. So I hopped on and took it to the front of the garage. I put it in revers and it cut out again so I pushed it in the garage. Today I went out to check the tow valve. I took it out and cleaned the threads up put it back in and it did not change anything. According to the dipstick I have the proper amount of fluid in it. I did have a drip that I fixed on the cylinder still nothing... does anyone out there have any tips to help me out? I’ve never had a transmission like this only manual transmissions. The model of this transmission is the sundstrand 90-1140.
      Any help would be greatly appreciated.
       
      Brian
