308-8 stuck in low range

Recommended Posts

BigRedGrizzly

Hi all... Looking for some guidance here. My 308-8 tractor had the low range shifter handle cut and it was rotated 180 deg. So it would face towards the back. The obvious sign is someone did this on purpose because there was probably something wrong. Well... I'm the the type of person who can let that be.  I had to start messing with it. So I got a replacement shifter arm and shift from high to low a few times. Every thing seemed to be operating fine. Then today I went to mow in high range and out of nowhere it slipped into low range and I can't seem to get it back into high. The lever moves all the way over to right but just doesn't seem to engage. Has this happened to anyone before? Any idea what the issue may be?

Alright.... After doing some research on this site I am thinking the hi/low range shifter fork is broken not allowing me to get back into high. Any thoughts on this matter. I suppose next weekend I'll be rolling up my sleeves and getting in there. :(

And why the extra notch for 2nd gear.    Too much slop someplace.

I don't know... I thought all Wheel Horses had that notch at second gear..

I'm curious too. I've never seen that before. I'm going to take notice tomorrow here at the big show and see if I can find one like that. :)

Can the rollpin that connects the linkage to the trans be sheared?

My guess is you may find this part ( toro # 116636-03 ) broken, Don't be intimidated as these transmissions are not terribly hard to work on. Best advice I can give is subscribe to Stevasaurus' you tube Chanel " Dino's Videos "!   It was a life saver when I did mine.

The roll pin is intact. I will need to dig deeper.

Thanks, Thor. I have been watching his videos. I'm going to try to separate the trans from the tractor this weekend then open it up during the week. I wonder if that part is still available. I suppose if worse come to worst I will stick it back in high and put the cut lever back on I don't shift it into low range. Ahh... The excitement of resolving issues....lol...B)

It looks as though the transmission in not centered in the tractor since both shifters are affected. Take the plate off the shifters come up through to see if it allows more room for shifter action.

 

Check the 4 bolts that go through the tractor frame into the front of the transmission case. Look for cracks in the rear frame plate around the bolt holes.

See if the main shifter is bent to the right. Perhaps it rolled at one time and bent both shifters. That round hole added to 2nd gear position is not normal.

Wow Garry, that's some interesting ideas!

 

Grizzly, did your old cut & rotated high/low shifter have the same problem?  Is it possible somebody just took a big hammer and beat the crap out of one or both of the shifters for some reason?  Does the other shifter look damaged at all?  How about the parking brake lever, or even the cover plate that Garry mentioned?

Garry,

 Thank you for your suggestions. I will definitely check into those.

Hi Tuna...  I'm assuming the person who cut the hi/lo shifter and rotated it 180 deg. did so on purpose because of this problem. So instead of fixing it they just manually/internally set it in high gear with the hopes no one like my self would mess with it. I can't help it. I just want to fix it.  So I replaced the cut lever and it shifted into low range without a problem. Getting back into high was troublesome. The shifter arm is not bent and it has full range of motion. I managed to get it back into high gear by rotating the drive pulley and pushing it into high. I felt it engage well. Made a solid click. I left in high for about 1 month. Then a couple days ago it jumped out of high and into low and won't go back.  I'll have to do a bit more investigating tomorrow afternoon.

Hey all.. I found this thread in transmission instructional area. I believe the problem I'm having is the same problem shown in this thread. Just wanted to share so you all have the same info I do.

Yes still available, should be through your toro dealer, or click the link in my post above. I paid more through parts tree for mine.

You should get a new shifter boot while you're at it, yours is pretty beat and probably allowing water into the transmission.  Does the fluid look milky or bubbly at all?

Hey all... Just back from a wedding in Massachusetts. I'm getting ready to dig into the 308. I have to make some room b/c the GT14 is in pieces waiting to be sand blasted. 

  Tuna- Good tip on the shifter boot. That was one of the first things I did when I got the tractor. 

  Thor- I ordered the shift fork before even opening opening up the trans. From the reading I've done I'm pretty confident this at least part of the problem. I understand they are somewhat flimsy and are known as a bit of a weak point in this trans. 

   So... I'm putting on my work clothes and heading out to the garage. : ) 

  I'll keep you all posted.

Hubs weren't to bad. I was able to beat them off with a dead blow hammer pretty easily.  Shifter came out pretty easily.

My wife heard me encouraging myself as I was working my way through disassembly. She said who are you talking to. I said myself...

Ok. Separation complete..

The case does not want to be separating easily. Any tips? Do the axle seals need to be removed first?

Use a couple putty knives to break it apart.  Sounds like someone used sealant on the gasket.

A sharp wood chisel works well. I've got an oldie I don't use for it's intended use anymore that is pretty much dedicated for tasks like this. :)

Yes! Success! I used a putty knife and just slowly started tapping away at it. It's apart. A good amount of oil was still in there too. Surprised me to that much.

Yup. I'll bet you didn't raise the front when you drained it. See the humpy doobie at the middle bottom bolt........holds the oil in front of it. Surprise!! :D

      Not sure on specific model. This 8 spd came attached to a plow I bought. It had some water in it for a couple weeks according to the prior owner. I drained it, sloshed some diesel in it, drained that, then filled with fresh oil. Spinning the input shaft by hand, I can see the axels turn. Hasn't leaked any oil. I'm not really interested in shipping, so I'd prefer local sales.

      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.
