Keep the vids coming. As a lifelong Kinesthetic learner, what you are showing makes complete what I have read and observed in the WSM. I have no near future plans right now to tear my 2023 X1100C apart, but your vids showing the internals really helps complete the understanding of how it works.
Thank you for the support! I agree, the manuals have good information, but if you haven't had it apart the cross sections are a bit confusing. Once you see it then it makes much more sense!
Hello. Thanks for the videos! They are very educational especialy this one. I have purchased used x900 and had HST repaired. Pre owners never changed oil for 32000 km and some of the pistons literaly melted. New parts with pistons are very expensive and used parts is nowhere to get. Something on ebay but... I wouldnt risk it. Would you be ready to sell me and send some used parts if I find some new issue with it? It would be really incouraging. Best regards from Slovenia, Matej
Great video. Crazy question... i am trying to rebuild the hdrostatic unit on one of these and i need a few parts. I need a couple of pistons from the larger driving block on the hydrostatic unit. I would be happy to buy them if you still have them kicking around. Thanks!!
good day . i was waching your video , seen your pile of broken parts . had my pump apart . did not find any thing wrong in it , end up pulling some of the valves apart to see if any springs where broken . i have a small peice i can not find where it goes . i would like to know if you still have your broken pump parts from the rtv x900 i am looking for the steel plate that holds all the valves .
Yes, both charge pressure and relief pressure. Check fluid level, filters. Sometimes the rubber hose can collapse on the hydraulic lines ans not allow fluid to move. Squeeze them to see if they are soft and squishy
@@SearlesStation thank you for your reply My charge pressure was 0 psi in neutral and high idle . I removed 2 separate relief valves and saw no scoring or anything bad . All components in place and moved freely. I did replace filters and hoses looked ok but will check that again . I had the charge pressure port in the back off and open and started it and hardly any fluid came out . Bearly dribbled .
nice video, out kubota x900 would not move. the trans low pressure had no pressure, the problem was an oil leak. that cased the hydraulic oil tank under the passenger's seat to be too low to supply oil to the transmission pump. the hydrostat is supplied from the hydraulic tank.
Hi there Our RTV X1120D 2018 suddenly stopped drive. Tries to move but no real torque transfer. Oil hydrostatic type issue. Both Gbox & hydro tank oil levels good. Unloader valve moving & can hear/feel it doing something when activated, while pulling on main control rod. Any ideas. Other than your video on how the gearbox works is there something on how the hydraulics operate & there controls.
Possibly an axel? Does it move in low or reverse? Or, Does it work in 4x4? If yes, lift the back off the ground and see if the tires spin. (Typically the passenger side will spin first) Perhaps try the differential lock to see if the driver side rear spins. If none of that works, it might be in your hydrostatic area. You can pressure test it or have the dealer pressure test it to see if it's pumping.
Can you PLEASE explain why did that transmission have a great hole right where the 4 wheel drive shaft came out and it appeared to be welded, I’m aware you purchased it and it didn’t happen to you but just thought you might know why that has happened. Reason I ask is, mine blew a hole exactly in the same place and Kubota Australia replaced the housing free of charge it’s not under warranty either, they actually done all the work and didn’t cost me anything, so just wondering are they hiding a known fault. I actually did hear from kubota delivery drivers that said it’s common when they are in snow and the wheels are spinning then it hits hard ground that’s what causes the housing to blow out under pressure. Have you heard of that happening.
Yes, there is a flaw in the casting and how the bearing sits in it. It wears and then breaks! It's very common and it's good to hear they are taking care of people on that. It sounds like the new casting has the issue fixed.
Thank you for sharing. I am fascinated by the Kubota RTVs and hope to own one someday. I wonder if the D1105-T made by Kubota will fit. People will RTVs crave more speed and HP. The D1105-T would do it.
There is a shock that dampens the return to neutral on the linkage. My guess would be that, that shock is bad and not slowly returning to neutral but the spring is pulling fast. Have someone step on the foot pedal while you watch that shock or just take it off and see if it is any good.
@@SearlesStationhello it’s been few months since I asked for help. I finally got my RTV running. I finally figured out the issue. My issue was it wasn’t going for or backwards and it would be full throttle and not move an inch. I replaced the two transmission filter is the way back and Waalaa it moves now and runs awesome. It’s been sitting for over 13 years about give or take. Also the fuel filter
Hi. Got a question you may be able to help me with. I have a 2018 1100c I just bought used. I decided to do all the preventative maintenance since this is new to me. Today I tackled the HST. I changed out both filters with new Kubota filters. After I changed them out I took it for a test ride and things were fine. I then checked the fluid level and found it to be way overfilled. I decided that I would loosen the big filter and let fluid drain from that since that filter seemed to leak fluid the entire time. After what i thought was enough fluid removed I put the filter back on. Now I have no transmission. I did all the preventive things I found on the internet that included lifting the wheels off the ground and running it till the wheels spin. Once that happened I took it for a ride. It was very sluggish and when I got it up to speed and lifted the gas pedal it was like someone hit the brakes hard and then it would jerk forward. I suspect either there is air in the system or the pumps aren't getting fluid. Nothing I have done helped. If it sits for a while it won't move until I raise it up and do the pedal thing until the wheels move. I even reverted to putting the old large filter back on to see if that changed anything. (it didn't). So before I call a dealer I am wondering if there is a trick to purge the system of air or a way to see if fluid is getting to the pumps as they should. The fluid level is currently correct. Any help is appreciated. Lou
With the hydraulic transmission there is no coasting like a regular vehicle. If you take your foot off the pedal it does come to an immediate stop. That is normal operation. There shouldn't be air trapped in the system after a few moments of operation. It should clear itself. Which location are you checking for fluid level? The orange/yellow cap under the bed is basically for the gears only. The tank under the passenger seat is the operation fluid. If that one is low, that could be your issue. Lift the seats, take out the tray and you'll see a rubber plug on the passenger side. Check that, or let me know if it's at a correct level.
Funny that I just got your response. I just returned from the kubota dealer and when I inquired a kind man said "did you check the tank under the passenger seat". I did and it was almost completely empty. I put in 1 1/2 gallons of udt2. Started in up, let it run a few minutes then drove away. Problem solved! Based on how hard it was to open the filler plug I guess it has never been checked or topped off. Thank you for your help.
The unloading valve releases the pressure built in the hst. If the pressure isn't released, the gears are bound so it is difficult to shift out of gear to another gear. I do have a video on the unloading valve.
@SearlesStation thanks. I have 2015 x1120d it stopped moving in forward an reverse. I found the cable this to unload valve broken do you think would cause this
@@wisconsinbigcheese6309 I don't think it would unless the valve is depressed. Where are you in WI? I'm in southern MN by New Ulm. I'd take a look if its not a hassle to bring it this way
Appreciate you uploading video! Why do you need a transmission. Is it possible to hook up drive motor to a drive shaft directly? Have a hydraulic pump hooked to engine. And go directly to a drive motor to drive the shaft? And do away with the transmission.
I have a 2015 RTV x1100c and it has stranded in the field. How can I disengage the transmission to tow it back to the shop? Or can I just pull it back to shop without disengaging? Thank you for any help
You should be able to put it in neutral... Press the brake hard and try to shift it. If that doesn't work, there maybe be an issue with the gears, if that's the case it may not move. Pull the orange/yellow dipstick and look inside to see if you can see any gear damage.
It's not hung in gear the fuel shutoff solenoid is bad. I just wanted to make sure if I could Pull it back to shop without disengaging hydro. Thank you
You have found you calling lol😮. So many of us want the Kubota reliability with the heat and air but just hate the no power or speed. 30 mph with power is all we need and don’t lose the reliability factor. Make more videos ,machine some custom parts show us the available of what engines with more power would fit without problems . Make a front locker for them . Open a shop we will all ship our machines to you for modifications you will be a billionaire. Thanks 😊
After releasing throttle on a downhill it will stop very slowly or even will not. And I a missing some power for acceleration ur uphill. I have set a linkage to hidrostatic motor that it does not turn wheels when in high gear and lifted. Any idea what it wrong. Thank you.
These will come to a stop or very slow down hill. That's how the hydrostatic system works. If it's in gear it will only move if the throttle is in acceleration. They do lose speed up hill. I have a video showing the uphill speed. Check that out
I saw your video and I expect to come to a stop. But mine would not. My friend drowe it yesteday and he said it should brake much more than it does after relasing power becouse he owns one and it does so. Can I try to adjust something? Thanks
Your pressure relief valve may be stuck open. That would allow for loss of acceleration as well. This video talks about hard shifting because the valve isnt being pushed, but yours may be always pushed or bad. th-cam.com/video/q-C3KzQ6NwA/w-d-xo.htmlsi=u67twtgdW27JuLPM
When I have it on flat or lifted rear wheels and in high gear it will not move. It even shifts good without pushing brake. But I lack of acceleration after 10mph. It will creep to 20.
Check the hydraulic hoses for collapse or softness, that can restrict flow. Your hydraulic pump or motor may be bad, the relief valve may be bad, their definitely seems to be something wrong with your hydraulic system. Change fluid, filter?

Just looked through my parts. I really don't have any that would be good. They are all worn pretty well.
Did you ever get the rear pumps replaced? Didn't see the next video available.
I swapped for a good used one. This one was too far gone 😪

My Kabota will not stay in high gear. It makes a popping noise. Any ideas?
Which model do you have?

Hi there
Our RTV X1120D 2018 suddenly stopped drive.
Tries to move but no real torque transfer.
Oil hydrostatic type issue.
Both Gbox & hydro tank oil levels good.
Unloader valve moving & can hear/feel it doing something when activated, while pulling on main control rod.

Other than your video on how the gearbox works is there something on how the hydraulics operate & there controls.
Forgot to mention tipper body seams to work correctly so maybe pump all OK. Just hydrostatic drive fault.
Possibly an axel? Does it move in low or reverse? Or, Does it work in 4x4? If yes, lift the back off the ground and see if the tires spin. (Typically the passenger side will spin first) Perhaps try the differential lock to see if the driver side rear spins.
If none of that works, it might be in your hydrostatic area. You can pressure test it or have the dealer pressure test it to see if it's pumping.
Do you rebuild the pumps for a 2005 rtv900?

If the rtv900 is slowing down faster than usual, how do I adjust that? It's the not the brakes

My 1140 CPX just had something break in the transmission. The motor works fine, but nothing is turning outside. What should I do? Is it worth fixing?
It really depends... Does it work in 4x4?
The 4wd has been broken for a while but the drive shaft does turn when I engage 4wd. Nothing to the back end
It sounded like something broke when I was going up a hill. I thought it was a u-joint at first, but it's definitely in the transmission
