Daryl, looks like you have been getting expert help.  The only thing I would be able to say for help a few posts ago.  Maybe take those bolts out before trying to split the tranny.  :ychain:  TORO still has the gaskets for that trans also.  You should not have to use sealant when you put the halves back together...as long as everything looks clean and flat.  :)  BTW...welcome to Red Square.

 

So where are you at now in this process??  :)

Here is a vid showing the high/low shift fork in action. 

 

Stevasaurus... I'm getting ready to disassemble the transmission. I'm not sure if there is a way to get at that hi/lo shift fork without removing the gears. I'll be using the thread I posted earlier for reference.

Yes, you have to take everything out to get at the hi/low.  The video I did with the 10 pinion differential may help a little...it is similar.  You have 2 detente balls between the 2 shift rails and 1 detente ball in the hi/low mechanism.  Take care when you pull those apart, not to lose those balls.  If you do, they are 1/4" stainless steel and available at any ACE hardware for about $.25 a piece.  :)  Your transmission looks really nice and clean...well worth the effort.

Thanks, Stevasauras... I'll be digging in this weekend. I can't seem to order the gasket. I'm not sure if I'm doing it wrong (searching for it). Part# I have come up with is 3912. Anyone has any guidance on whether or not this part is still available and where I can get it?

Your TORO dealer has the gasket...about $6...your part # is correct.  :)

Ordered... Thank you. :handgestures-thumbupright:

 

Ok men... BIG UPDATE!

Here's the deal. Shift fork is worn

to garbage. Two different size detent balls, spring for detent balls is broken. Getting the cup plug out to get at the ball required some enginuity. 

Here are the pics and vids detailing tonight's work.

I drilled a small hole in the plug and and screwed a screw into it and prayed it out.

Removed the shift forks and spring and balls. Noticed the broken spring and 2 different size balls.

How it should look.

These are the replacement parts I ordered.

Here are the 2 vids. The first one is me realizing the gear is getting hung up. 

 

This vid is me realizing the issue. 

 

Also.. I think the small detent ball and broken spring was contributing to the slop in second gear requiring the second gear on the shift box panel to be made bigger. Smaller ball equals more room needed to push the shift fork. Makes sense in my mind. 

Now... My least favorite part... 

WAITING!  Hopefully the parts get here tomorrow or Sat. 

Have a Happy 4th of July, all. :USA:

Amazing isn't it the stupid plug is so expensive.  As for balls i bought 100 1/4" balls from McMaster, i do not bother to look for them when they pop out during reassembly (which they always seem to do):P

Great videos!!  :handgestures-thumbupright:  Do you have a copy of the manual?  It has step by step instructions for taking apart and putting back together.  As far as that gear hitting where you are showing, it should not.  It is not from wear on the fork, remember there is a spline shaft that sits inside of that gear.  If there is enough slop for that gear to hit, it may be a worn bearing that puts slack in the spline shaft and allows it to move enough to hit.  :think:  I also think that someone has been in there before.  That weld does not look factory and no way you would have 2 different sized detente balls.  Pretty cool to see how things work though, is not it?  :)  You are doing fantastic.  Thanks for the videos.

    If you don't mind a little humor?  I started watching the videos and thought you might be a smurf...then I realized it was just rubber gloves.  :ychain:

Here is a link to the manual...you want "Section V".

Thanks for the manual. I did not have that. It will be very helpful for the re-assembly. Thanks for the words of encouragement. I'll keep you all posted as the parts come in.

Hi all.. I got the new shift fork in today and installed pretty easily. I thought I was going to struggle more getting the spring and detent ball in. 

Here is a pic of the old one next to the new one for comparison. 

0C3D0FC2-D1E3-418A-8F3F-953D020ECABD.jpg

Here is a quick vid of it functioning well. I checked the needle bearings as suggested by Stevasauras and the appear to be in fine shape. When the input shaft is spun just a hair it helps align the gears perfectly allowing the low range gear to fully engage.

Looks like you're enjoying it immensely. I did the same though the fork itself was completely unattached and, thankfully, stuck in high. Steve-O's videos guided me through it. That fork wear suggests long operation low on oil to me.

Before I found/joined this site the I knew the tractor in my AV needed transmission work and I got an estimate at a local repair shop which was well over 1000 dollars . Found this place, scared stiff of opening the tranny up and not being able to get  it back together Steve -0  promised that wouldn't happen and thanks to his vids and guidance the old C-101 now sits with a fully restored tranny for probably under 200 bucks. With the bearing part /crossover numbers here I saved a ton buying the Timken bearings all available on Amazon .

Ugh! So, I went to order those parts from my phone the other day and must have been distracted, squirrel, because I never, squirrel, completed the order. As I went to check the status of the order it became clear to me that I never went through the checkout process. Just put the parts in my cart. I have two problems. I'm easily distracted and have two young kids that demand a lot of attention. It could have been a simple... Dad.... I'm finished... Come help me in the bathroom deal that compromised my effort. Oh well. Set me back a few days but it gives me time to get after the GT14. Every cloud has a silver lining.

Been there. Done that.

 

At least you have other project tractor to keep progress moving forward on.

Hey Fellas... The 308 is buttoned back up. :greetings-clappingyellow: The transmission went back together very smoothly. Stevasauras's videos were the KEY to my success. :thanks:

I was very intimidated and nervous to open the transmission up. But like with many of the projects I get into they turn out not being too bad. I have a much, much better understanding of how transmissions in tractors and motorcycles work now. This was a fun and educational experience. 

Now as I ran it through all the gears in high, everything seemed tight. I was so nervous to shift it into low for the fear of having to get back into it if it didn't work. I shifted it into low and it work fine. I went to shift it back into high and it was like it was in neutral. Nothing. So, I put it into 2nd switched it to high as I let out the clutch and it grabbed into high again.  I guess it works OK. just seems to stick a bit. 

Here are some pics of the reassembly. 

New balls and new spring

Outstanding job Sir, and thank you for the kind words.  :handgestures-thumbupright:  Your transmission looks great, and it should last you a very long time.  Excellent pictures by the way.  :)

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

      By Doug B
      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.
