sundstrand 90-2046 inout port location

Recommended Posts

I have a c-160 I have a lift valve to hook up to a replacement sundstand 90-2046. I want to make sure i hook it up to the right ports for lift and return. any pics/diagrams or "now this is what ya do " .. are appreciated. also does anyone have the thread size for the hose ports? the reason i ask about ports threads its it seems the the ports on the valve have a larger fittings than the 90-2046 pump. so hoses dont thread in on the pump.and yes i checked all the ports on pump because i'm not sure on the hose connection location... they just a size too big. 4 or 5 on pump and 5 or 6 on the lift valve.

Here is a chg 12 90-2046 power unit.  (I swiped these pics from someone....).

Auto parts ought to source the hyd port adapters.

Are you sure the 90-2046 Sundstrand will bolt to the C-160 transaxle and work right?  That is, will the drive gear of the 90-2046 properly mate to the 1st driven gear of the C-160 gearbox?

If the valve is the only addition, I would think the fluid direction through the valve would not matter.

The valve will move the cylinder in the direction you select depending on where the cylinder hoses are connected.

ok this is the background on the C-160.... i bought it last summer (plow, weights and chains and a sporting 1984 front seat from a ford of some sort reclineable no less..$100) and used it as a tow vehicle for moving logs around till i lost the former pump..i replaced it and it condinued as a tow vehicle.... I dont remember if the valve hoses were even hooked up to pump, never used it for plow or implements, and i doubt it was  because the old pump is a 90-2046 and the hoses don't hook up to it.. i still have it and used it as a test platform.. the valve originally on it and  why i started this thread is it a different style than one shown in your pics Dave.. the fluid in and out ports from/to pump are on either side of the main valve body and look modular. the one in picture is same as one i just picked up and it hooks up fine and is not modular.  I'm heading out after this post to finish ass'y and test..  I guess my question now is ... if the modular ports on either side are swappable for various configurations they must be available .the valve I had originally is correct for some C-160's as i've seen picture postings of that style but the port sizes have me believing it is from another model. It is stamped  Ward Co

got it all hooked up..... a few thing I learned along the way.  For the hydraulics to work for implements, and this is important,  their must be a "lift valve kit" installed  which includes lift valve, hoses and a "needle valve and spring" not supplied on standard setup tranny, the ports on the Sundstrand Hydro Gear 90 series are either 5 ORB thread ( o-ring boss) or 6 ORB thread. Make sure you have the correct hose length... too long they get in the way ..too short and they will fail early due to stress.

      I’m looking for a transmission dipstick to a D-180. Let me know if you see one.

      Hey guys,I have a dilemma I need some help with. I have a 1969 GT 14 that I replaced the transmission and pump on. For about 2 weeks afterward everything worked great, but while mowing at a pretty good pace I noticed a shudder and the tractor slowed a little but not bad. The more I rode it the slower it got until it barely moves. What stumps me is the hydraulics are still very strong,as in I can back the 3 point under the bumper of my truck and if you lift the arms all the way up the front wheels of the tractor will clear the ground. Have checked the tow valve and checked the internal filter,but no luck. I have also checked and replaced the forward and reverse bypass springs and the lever is moving the cam to full travel, forward and reverse. Any help would be appreciated.

      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.

      New here! hello everyone! In a bit of a pickle here. My father owns a 1993 (I think that is the right year) 520H Wheel Horse. I don't commonly work on tractors but it seemed simple enough. the axle snapped on the left side, so it needed a new transmission. My dad bought a used transmission and I went to work changing everything out. The hydraulic pump that the engine's drive belt attaches to went to a different model/year of tractor, so I had to remove that part and swap it in from the old transmission. In the process I lost all of the oil in the pump (I mention this because I wonder if it has to do with my problem I'm having). When I reassembled everything I started the slow process of filling the transmission. I filled it up and started the engine. When moving the lever forward or backward, it had a tiny bit of power for a little bit and then lost power. The transmission wasn't doing anything, anymore. I though maybe that hydraulic pump needed to be primed, so we took the top hydraulic line off of the hydraulic pump right above the drive belt and used a transfer pump to pump some oil into the pump case. This still didn't work. I don't have enough experience with these hydrostatic transmissions to know if we got a bad transmission or if there is something obvious that I am missing when it comes to a transmission swap. I ask for any insight and help please. If you need pictures or any other info, then let me know what you need. Thank you!

      I have no understanding of what it is like to push one of these when the trans is disengaged and motion lever is in the forward position as the manual mentions. I hope this is not old ground and that I am not cross posting. With the trans disengaged and motion lever set forward there is still something spinning in and about the transaxle that is giving resistance. I need to know if this is normal or if I should be expecting more of a free wheeling experience. In effect, much less resistance. Thank you for comments or pointing me to a topic that already covers this.
