Wheel Horse 14 Transmission Fluid

19 posts in this topic

I was looking to change to transmission fliud in my Wheel horse14. The manual calls for 5 Qrts of dexron or Type F Hydrostatic oil so I purchased 5 Qrts of universal ATF at Tractor Supply.

Today, I was ready to start with the change and I noticed that the fluid thats currently in the transmission is white in color. Is this normal? Most of the time when fluid is this color, it has water in it.

I would like drain this and replace the fluid but I want to make sure what I replacing is compatible.

Thank You

Might have condensation in the oil. If that's the case I would drain out as much as you can(about 3-4 qts) and refill with fresh ATF and run it for about 30 min. re-drain the trans and change the filter at that time. Refill with more fluid. When you drain the fluid , you will not get all the fluid out. Some stays int the pump.

I'm guessing this is a '73 14 HP Auto?

From what I have read, these came from the factory with Dexron (red ATF) but soon after they started using engine oil instead (I forget what grade, it has been posted before). Mine has always had ATF in it.

It sounds as though yours has water in it, although I have never seen what ATF with water in it looks like. The hydro units are so well sealed up, I can imagine how water will have got in there.

Anyway I'd gt that stuff out of there. Scotts advice seems good to me, I'd probably keep flushing until the fluid is clean, water would be pretty damaging to all those close tolerance parts in the pump.

Water or coolant in my field of work turns atf almost semi clear white when the trans cooler in the radiator springs a leak. Also pull the filter off and drain out as much as you can from it also, then put it back on tell the fluid looks clean and red. My 74 c160 uses 10w30 motor oil in the trans. that was the start of motor oil in the sun strand transmissions.

I dont mean to sound like an idiot but I was told that the hydrostatic tranx has the filter but mine does not. My machine does not have a hydrostatic tranx. If mine has a filter, where would it be located? The manual shows a screw in filter, but I dont see this on my machine. I think the manual applies to both types of tranx.

Thanks, Anthony

OK then, the manual trans does not have a filter, and does not take ATF in the gearbox.

It might be best to post the model # off the tag on your tractor so we can be sure of what tractor we are talking about.

If it is an 8 speed transmission, it should take about 2 qts of 90-140 wt gear oil. But since your old oil has water in it, I would drain it, flush it with a qt of kerosene and a qt of ATF, and then refill with the gear oil. Have a look at some of the "transmission flush" threads that are on here.

It sounds as though you need a shifter boot as well, that;s where the water normally gets in. They're available from your local Toro dealer for about $5.

I think we need to know what tractor your working on before any more is said.

Once I fill with it a qrt of kero and a qrt of ATF to start my flush, is it safe to run it around for a short while and get it warm to help loosen up the gunk?

Thanks, Anthony

I would not drive it with the kero in it, but put it up a stands, and run it through the gears, now with the ATF in it I drive them around some, or I put a kid on it and they drive it around, then when it comes out clean fill with gear oil.

Thank you very much guys! I greatly appreciate your help. I'm going to get on this done tomorrow. I hope with a few years experience on these machines maybe I can help others like you guys have helped me.

Thanks,

Anthony

I have a 1977 b80 that I just pulled the plug on the trans. Chocolatey looking oil came out... It has a square plug on the left lower part of trans, and an allen plug on the bottom. I pulled the bottom plug and nothing came out. Maybe half a quart on the side plug. Is there just junk plugging the bottom then? I took a mirror and looked in the hole and it looked metally, did not think to stick something in the hole... What would the purpose of the side square plug be if the bottom is the drain?

I'm guessing yours is an 8 speed?

The plug on the left side of the case is the fill point for the early tractors that didnt have the filler/dipstick on the top.

If your oil looked like coffee it has water in it. Do the kerosene/atf flush as descibed above, and then refill it with clean gear oil.

The side plug looks to low on the trans to be a fill plug. I did use it to start adding oil... the dipstick hole takes so long to fill. But to get the oil on the dipstick to read full, the side plug would never do it, the full level seems higher than this plug. And yes, it is an 8 speed. Thanks for your help!

The mid sixties 6 speeds didnt have the dipstick so they used this as a fill/level plug. But they did add a pipe nipple to it to raise the level probably an inch and a half.

When filling yours, remove one of the bolts in the middle on the top of the trans. It will act as an air bleed while you fill it through the dipstick tube.

Thanks, that explained it! Now I have another problem, filled the fluid and it started coming out of the left axle. My guess is a seal is bad. When I had the tire off, I noticed some play in the hub the tire goes onto, the seal was loose as well. I will probably need to look for a different thread to see what this is going to take...

    • Complete Pedal Kits for Hydrostatic Wheelhorse / Toro Tractors
      By mattd860
      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: https://dl.dropboxusercontent.com/u/99750546/Wheel%20Horse%20Hydro%20Foot%20Pedal%20Instructions%20V3.pdf
       
      I am selling these kits for $250 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.

    • 3 SPEED #5025 UNI-DRIVE REBUILD
      By stevasaurus
      My intent here is to show lots of pictures so if anyone is rebuilding one of these or some of the others...you can do it without fear and I am adding some very helpful information. I had a post that lead up to this that has some information in it also, and while it overlaps, I wanted to do the rebuild separate. This post is meant to be used with the manual...the pictures help explain better then the pictures in the manual.

      Now I want to share what I learned as I rebuild this...I realize that some have done this, but this was my first time (transmission virgin) and I know I am not the last one to do this. If I can help or make this easier, then I have given back a little from all the help I have received from this site.

      This is a shot showing gear placement in the left side of the case. Notice the bevel of the reverse gear (front right). The left side is the shallow side of the transmission halves.


      These are the parts of the differential..the 2 casings on the outside, the 2 axles, the differential bull gear, the 4 posts and the pinions that go on these, and the bolts and nuts that hold it all together.


      I can't get enough looks at the gears before I tear it apart...next 2 pictures are for future reference.




      I found a good assortment of 3/8 and 1/2 sockets that made fair to good arbors for pounding out and tapping in most of the bearings and seals.


      These are the bearings and seals you need to do the R&R. You can get all the stuff from Toro or the site that Jason gave in the related post. One note...the Toro#1303 seal is discontinued. This is called a cup seal, because it has a cup shape. I replaced it with a kind of match (SKF #7410) same dimensions but more like a regular oil seal...it will work. This place used to be Berry Bearings in Elgin...now it is "Motion Industries"...the web site MotionMRO.com...they can match up any bearing or seal. Excellent info. and prices were very good.


      Shot of the bearings and seals removed, cleaned and sanded. Used Valspar Restoration series...I like the red match with my 702 and I like the hardness of the paint.


      Showing bearings and seals installed...notice (arbors on right).



      Putting differential back together...show axle in place with bolts in place.


      Added pinion posts and in 2nd picture...added pinions (alternating one up and one down).



      Added Bull Gear


      Added other axle and case and bolted together. At this point, make sure you can rotate the axles...they should rotate in opposite directions.


      Placing input shaft and gear (one piece) and the reverse idler shaft.


      Installed the 2nd & high shift rail and fork. (one on the left). Also installed both ball bearings, spring and stop pin, and low & reverse shift rail. The 2 sliding gears were then placed...the grooves face each other and the smaller gear goes on the bottom.
      I had a pencil magnet that I used to hold the 2nd ball bearing, while I took an Allen wrench through the hole to hold the bearing out of the way while I placed the low and reverse shift rail. the picture also shows the reverse idler and brake shaft in place.




      Another view showing forks and gears.


      Showing reverse idler (bevel up...I hope) in front. Splined shaft installed through the shift fork sliding gears. The cluster gear is then installed( 2 wood-ruff keys here...one on each end). Also, the differential and axles are placed (note the nuts are facing up).


      different angle


      yet one more angle


      Put together..old 5 gal wood create works great as a work bench (all shafts fit through and keep work level). Used a hard rubber hammer to tap halves together.
      No leaks when I filled with 90wt gear oil...approx 1 1/2 qts. Checked shifting and started to put the 702 back together today. A final picture or a video tomorrow (hope).


      I want to thank Rickv1957 Fan, MikeRJ, Buckrancher,Suburban550,IndyWH Smokin'Joe, the Helmett and Charlie for all their help and advice...a huge thank you guys.
    • 1960 Suburban help please
      By 378Pete
      I have a 1960 suburban 400. Can anybody tell me what fluid belongs in the transmission and how much of it? Do i pour in top plug until it comes out of side plug under axle? I have used the search function but got multiple answers and left me more confused. Thanks for the help.
    • 8 speed transmission
      By Dennys502
      This is a 1997 or newer transmission according to the casting number for the side case - I'm thinking its a 1997. Never used - never had oil in it. It had some rust in a few spots so I sandblasted it and painted it with some red paint I had. I didn't do the hubs.
      I decided to replace the seals and gasket since its been sitting for all these years.
      Asking $800.00.
