314-8 Tranny problem

Recommended Posts

Hi all, my first post here. I bought a 314-8 this past fall, with a mower deck and snowblower. All was fine, other than a sticky first gear. I replaced oil, new fuel filter and gas line on the tractor, and also new belt on the snowblower. First snowfall it worked well, but ran a little rough. This past week, I got one swipe of the driveway done, and when shifting from reverse to 2 ( couldn't get it to shift into 1 and stay) the Tranny wouldn't engage, leaving me stuck.  No reverse, no forward. Engine still running fine, drive belt seems in good order. 

 

I pulled the shifter today, which is intact and looks fine. Trans fluid looks a bit low, and milky, so I think some water got in there. The gears seem to shift smooth, but the tractor just won't engage.  I called the guy I bought it from, who assured me all was in good order, as I can't seem to find someone to work on the unit here in RI.  Any thoughts???  I'm OK mechanically, but not a whiz, and not set up to pull and rebuild a transmission.

Have you checked the keys in the axles and the input pulley?

Well, It's pretty easy.    If the gears are shifting OK, there might be a simple disconnect in the drive train.    The first check is  with the tractor running and the transmission in gear, check both axles to see if  one is turning inside the hub.    If one is turning, the key is sheared and must be replaced.      If neither axle  is turning, then remove the belt guard and check to see if the transmission input shaft turns when you turn the pulley.  If it doesn't turn the shaft, the key is sheared or lost. 

 

    If the input shaft is turning and neither axle is turning with the transmission in gear,  you have a broken gear or shifter fork  inside the transmission and will have to replace or rebuild the transmission.

Do a search for  " transmission repair" and you will find excellent instructions  by member stevasaurus on these rebuilds.

Do the checks Ed mentioned. Also make sure your hi/low shifter is fully engaged and not between the hi and low. Please report back when you do that. We don't want to rewire the house cuz the light bulb burnt out. You definitely need to flush the transmission as well. Make sure you have a good shifter boot on it to keep water out.:)

I need to replace the shifter boot, looking at it last night, its dried and cracked.  Also, If memory serves, flushing the tranny is best with diesel and let it run the the transmission for a few minutes?  Ill get into the keys tonight.  I tried to remove the lug nuts last night to make my life easier, and it appears that someone was kind enough to put some lock tite on the threads for me.

Yea, diesel works well. Drain the gunk, dump in a couple quarts of diesel and drive it around a bit. Loctite on lug bolts:no:

Are you sure the lug bolts are loctited.  If you see red on the threads, you will need heat...400deg.     They may just be rusted....apply PB Blaster to the bolts inside of the hubs where they are tapped thru.  When you drain the tranny,  lift the front of the tractor about 12" to get it all out.

Hi all. Thanks so much for the support!  OK, here's an update. I came home jacked up the rear end and started up the tractor. In all gears, no spinning of the wheels. Seems to be moving freely. The input wheel is spinning, as is the shaft. No movement on the shafts to the hubs. The lo hi gear seems to be moving, but I can feel it grinding and I don't think it's catching. On the Tranny, there is about a 1/4 to 3/8 gap between the "stopper" on the lo hi shift arm and the Tranny case. I'm beginning to suspect it's the lo hi gear??

I agree. That hi/lo fork looks to be a likely suspect. May be time to open her up. It's not difficult. Watch Steve's video and there's plenty of help here. :)

Scroll down the Main Page to the WHEEL HORSE REFERENCE SECTION...see INSTRUCTIONAL THREADS AND VIDEOS...clink on TRANSMISSIONS. 

 

Contains a few threads with pictures and videos on 8 speed transmissions.  My "6 speed #5060" thread has the videos that will help you, but your 8 speed hi/low mechanism is a little different then the #5060 trans.  It is close enough to get you through it, but I recommend using my thread and dgjkls6's thread "Idiots guide to 8 speed transmissions" together as reference.  His thread has the pictures of what your transmission looks like inside.  :)   Also, we are here and will help walk you through it. if you need any help.

I'm really shocked at how helpful you all are. Thank you all, again!  I'm going to start in on this tomorrow.  I'll post pics and progress.

@Kirbyhorse , please start a new thread in the same section as this.  We would need to know what horse model you have and an explanation of what you think is going on.  We solved a few things in this thread above, and you did not give us enough information to know where to start.  When you click on Transmissions on the main page...you will see a box that says "start topic"  It is the best and fastest way to go.

BTW Welcome to Red Square...  :text-welcomeconfetti:

      Hello,
       
      I have what I believe is a 1989 312-8 wheel horse and need to purchase transaxle dipstick.  I do not need the tube just the dipstick, however, if the dipstick comes with the tube that's fine also...

      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://www.dropbox.com/s/zp8ty4oxctzvt8a/Wheel Horse Hydro Foot Pedal Instructions V3.pdf?dl=0
       
      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.
