Where can I get a repair manual for a hydro gear transmission 355-2400? I have one to repair and would like a manual that has the torque specs and rebuild procedure. Thanks
Best instructional video I’ve ever watched. Thank you for doing such a great job. That barking dog was driving me nuts!
cool hydros same size motors as commercials. I have a cub cadet tank which was a very early 2006 version of these hudros - the gears as it has a separate case for that. These are sweet. Btw my 14 yeard old mower with 1500 hours hydros are still working. Change that oil and them filters.
Fakin dog!!!
Yep bailed at 12 min.
Thanks I worked in a hydraulic and jacks , pumps and a machine shop and I rebuilt the jacks abd the speed reducers for belt lines and wheel units for mining equipment and the video is a very good one I also like the one of resurfacing the motors and housing and smoothing up the surfaces are great videos to help with the expensive world of having a little something on a poor mans budget thank you for your help and taking your time. 👍🏻
Definitely the best how too video on KZhead. For anyone doing this I found that the perfect thing to pull those seals out is just a little 1 gallon paint can opener.
Great video, thanks for taking the time to make and post it. I have a Kubota with ZT-2800s but after 6 years of service they are still running like new. Greetings from Australia.
Enjoyed the video and the presentation. You're an excellent mechanic and do (high) quality work. Thank you!
Never mind man I figured out what I did. I ended up purchasing a new cover or cap for the pump and its twice as thick its heavy duty big time but I put it all together and Boom it didn't work so I remembered what you said about the cover being on the wrong way so I flipped it around and it started working really awesome! It was sucking the oil from the reservoir tank faster than I could pour it in. Thanks for the video it helped.
This is the second video on repairing this pump and also the best.
You did a great job. Ive worked for transmission shops for quite awhile and just bought my first zero turn. Im not feeling too nervous about it going bad on me in the future thanks to your video. Also, if you use "Right Stuff" rtv you wont have to wait overnight to add the fluid. It cures VERY quickly. We use it in the shop for this reason. It also bonds very well to metal surfaces to the point that it cant be peeled off. It needs to be ground off with a wiz wheel. Its not cheap but well worth the price. Great Video!
That is an excellent video. I gave up doing the bigger stuff a few years ago and really enjoyed seeing you complete this job. Thanks for the great video's.
The bigger repairs, and larger equipment is where the money is.
That looks fun. I'm going to look for a junker so I can bring it back to life. Excellent video. You clearly know what you're doing. BTW, I came here after watching you sand down the hydro component which was very satisfying. I like learning stuff like this for some reason.
Spot on bud! Excellent tutorial on the ZT-2800 hydro. Very Well explained, and a very good video to boot. Been into to many of these over the years, hard to believe at times alotta dealers won’t repair these anymore! Throw it away and buy new. Crazy! Anytime I can cob these of junk mowers it’s well worth the time especially when parts cost what they do anymore. Just got done with one of these ZT units out of a hustler Fast Track. By- pass shaft busted in half. Great job! And take care!
Nice job! That’s one of the more complicated projects I’ve seen you tackle!
I'm sure it's hard to film the more in depth jobs due to being tedious and getting it done right. Filming is distracting and you don't want that when doing something as time consuming and precise as this job, especially when you only want to do it once lol
Great video I don’t have any issues with my mower but if I ever do won’t be hesitant to tackle that job, have done many Chrysler 727 transmission modifications for my 1/4 mile cars.
My former boss mentioned these units having a filtration system of them, ours are John Deere. Glad he is so observant and really is into small equipment like this. He saved my employer big bucks servicing this.
Great video very informative thank you so much, may the good lord bless you and your family with divine showers and keep the vids rolling.
fantastic video. Thanks so much for posting this. I feel much better about buying a z turn with 2800s now.
Great video from start to finish. I have the exact model with the same issue . Makes me wanna tackle the problem Myself ! Thanks .
My compliments and much thanks for a very well produced video and beautifully explained process. I'm about to dive into a similar operation on a Jazee Country Clipper and will do so with far more confidence in being able to pull it off now that I've watched you do a couple. Cheers.
You are one heck of a mechanic, great job!
Excellent instructional video! I really enjoyed it. I didn't fast forward at all. Now it's my turn to take one apart in order to repair the leak it has. I have a 36" Hustler Fastrak Commercial mower with ZT-3100s.
How many hours on your mower before you notice a leak?
Problem turned out to be the input shaft bearing. 630 hours
That's not bad I had a seal leak on zt3400 at 60 hours
I hit a small stump and my forward control stopped working but the left side control always sounded louder than the right when it turned now its highly noticeable....Thanks for the vid ....It gave me the confidence to attempt the repair instead of spending $1,000.00 in repairs
Great video, excellent detailed assembly.
Great video! Also, I used a pair of inverted snap ring pliers and they popped the charge pump orings right out.
Great video! Brought back alot of memories of my days at hydrogear putting those beasts together!
So did your job move off shore??
@@REVNUMANEWBERNnope...i found work elsewhere!
What would the torque be on the case cover bolts?
Someone in another YT asked if the different trans levels were interchangeable, I'm assuming in bolt mount locations? Are any identical in mounting points??
@@REVNUMANEWBERN if memory serves me correctly some of mounting holes would line up across the different product lines. Otherwise I would assume the units aren't interchangeable.
Great job my friend, I am looking at Zero Turn mowers getting a feel for these hydrostatic transmissions.
O HELL YEA i never seen inside of one of those ive got a bad boy to it was great watching you save a $1000 bucks and now i know how to rebuild them . ive got a zt pro from 2010 still runs great i never had any problems before thank god ! be cool thanks dude !!!!
Bob, that is one of the best videos I’ve ever watched.
Lindsay Spotts Welcome to the club I met someone today at the garage sale that knew me from KZhead it’s a small world after all.
Very informative! Thank you! I have a Worldlawn mower with 3200 trans in it. The reverse on the right side gradually got worse over this past mowing season and during my last mow of the season, it quit all of a sudden. I'm hoping that its the same issue as yours.
Great job Bob.
A great video. I just don't know how you can keep track of where all the parts go. A good job done.
Man nice video. I love learning something new wish I would of kept my old one to redo. Vid I seen before replaced the old center on a cub $200 then, more now I bet and all I needed was sandpaper thx for the rebuild
Best to take it to the shop for this project
Nicely done, mate.
You just saved me hundreds of dollars. Thank you
Great video, thanks for all the info
Great video! But I must say I didn't need Fido's constant input.
Nice thorough video! Thank you!
Outstanding!! Yeah that's my fear is repairing one and it not work right.
Thank you for your video and the way you explained ya way throu it all. . i think your link will be alot of help wen i tare mine apart. . thank yoh again.
Great job, very informative, thanks
Great breakdown video 💪🏽
grateful for this video. thank you !
Great video thanks for all your time.
You have the best video on how to do this. Other shit vids leave all kinds of important pointers out. Lol. Nice job. Helped me tons😊
AMSOIL hydro oil for me. Thanks for the fix!
First off I wanted to thank you for the great video that you put out really enjoy watching you work on those things I’m actually tackling similar project the sinner section I got a sand and redo I had the fan bearing go out so I’m rebuilding it question I have for you because I took that bottom plate off underneath and I didn’t market which way it needed to go back on and you mentioned in your video that it was a critical piece to putTo be put back on the same way just checking to see if you know how I could find out
Easy to understand, thanks
That barking dog in the background is a pain in the ass!
Jay Curtis Like so many neighbors, they don’t even hear it they are so used to it.
True story.
I am using this video to check my hydro on a 36" Hustler Fastrak.
Great job, Bob. It looks scary, but if you take your time, keep track of all the bits and kibbles and have a schematic to use as a guide it's easy enough and at $800 per side new, definitely worth the time to fix it yourself. Did you have to buy any new parts? It looks like you were able to save everything and just repair that valve. Bad Boys are pretty popular in my area, too. Thanks, Bud!!
Father law has several of these units and likes them the best over all the other makes
thanks for this video . I have this problem with mine, it's a toro mx 5060
How many of these have you worked on to achieve your level of competence, expertise and easy manner? When parts begin falling out of something, my heart rate goes up accordingly, when springs jump everywhere, I get nauseated. You make it look easy - which I'm sure it is not. Great job and THANKS!!! PS: Since you had unit taken apart, surprised you didn't go ahead and replace the power input shaft bearing (6203 bearing) unless they never wear out. Comments?
Excellent work, nice machine too. I wonder how or why the valve worked itself loose. During manufacture maybe?
Nice job buddy
Mr. DoubleWide6, thank you for this excellent brake down and repair. Learned so much that I have the confidence to repair my failed Troy-Bult 50" Zero Turn. I'm hoping the repair is as simple as a loose check valve, but, if additional parts are needed, I appreciate the sharing of your part source. I have invested far too much in this old ZT mower. To have the transmission go was a huge let down. Discovering your KZhead channel has breathed new life into my project with the hope that a DIY repair can be done for short money and not a $1500+ new transmission. BTW, where did you obtain the repair manual and exploded views of the assembly?
how can you reuse those rubber caps after you poked a hole in them to get them out and did you get a rebuild kit to replace all the other seals. thanks
Great trips for another’s hack job trying to fix something and actually making it worse. Would have been hard to catch the problem caused by another inability to rebuild this unit without this video!
What precautions did you take to prevent this reoccurrence? Also, I was hoping to see you change the oil in the transmission, I have never done mine and it's 21 years old. Thanks for the info.
Have same machine 2006 it's a beast with the Briggs and Stratton engine
excellent video! Thanks
That is a gerotor style positive displacement pump. It has a greater capacity than a normal gear pump in a much smaller space.
Nice to see you got it fixed. I have a Bad Boy identical and can’t figure out an issue I’m having trying to engage the blades, the pro clutch engages but the engine bogs down and dies. I have to try 3-4 times and feather the clutch off and on real quick to keep the motor running until I can finally get the blades turning. After that it runs fine.
i have the same problem did you get yours fixed?
I never did figure out the cause but it has got better over time. Right before my problem started I had pulley go bad so I replaced it. In the process I cleaned and repacked all the spindle bearings and greased them really GOOD. I'm wondering if I overdid it with the grease and the added weight in the spindles was causing the problem. I can engage the blades now and don't seem to have the problem with it killing the engine.
@@catfish307 thanks
Crap in the carby emulsion tube Main power jet.??
I have that exact mower, 2008 26 ZT pro and I have had nothing but trouble with it. I bought it with around 50hours on it and at 100 hours, all the spindles went out, at 200 hours the charge pumps started to leak and I replaced those and the spindles again and deck wheels. At 300 hours the Briggs 26hp engine started getting really hard to start, and now at 400 hours, the left Hydro will not work at all. I only use it for my property, so 4 hours per week during the Summer and change the oil every year. I bought a 2020 Hustler X One yesterday 60inch 27hp kawasaki. I'm going to sell the Bad Boy after I replace the Hydro on it.
Great video, Thank you!
I didn't find this video until I put the unit back together and on the mower. The problem I had came back. Those valves will be the issue because that's the only thing I didn't check. Time to do it again.
Awesome video! Helped me allot
Good job.
well done and thanks
Great video.
Watched your video and it was very informative but the camera did not pickup how the by pass pin goes on the center section for install. Could you inform me how the pin goes on the center section?
interesting how it works. But cost wise, how much difference in this somewhat complex repair vs simple replacement? Also no lock tight on check valve nut? The loose nut was a manufacturing defect.
Hey I got a new seal kit for ZT-2800 Hydro-gear trans and the seals in the charge pump now have 2 rubber rings but the new ones have 3 rings on the rubber. Do you know if its a design upgrade or have you heard anything or read it anywhere? I bought a kit because someone put the wrong o-ring in it and it leaks but it was working fine now after a new o-ring it barley moves at all on jacks stands I did notice you said to be careful how you put the cap back on. If you have any knowledge on those O-rings/seals let me know. Thanks and BTW great video!!!
Can u put the seal under ur fan on top with in in the mower?
Great video man. I have a question. What would make the wheel and axle move in and out? It just stopped moving one day just in one side and when I jacked it up the wheel I can move in and out. Is it repairable or do I need another transmission?
Thanks
I watched this video as a guide to take my drive apart. It would not go forward or reverse and I figured that I might as well try because it's totally screwed at this point. Well I have not found anything wrong inside. I was hoping that I had a loose valve like you did but both of mine were tight. I have not taken them apart to see if there is anything wrong but from what I see they are fine. My drive has the polished areas from the piston blocks and like yours I can't feel any grooves. Right now I'm at a loss as to why my drive wasn't working.
try belt issue or tensioner
Great video --Thanks
Fantastic video! I have an Ariens XD 52 with hydros made by the same company. Unfortunately Ariens markets them as "maintenance free," and they don't have filters. I don't have the the cojones to crack the case like you did. But great job and I enjoyed the video.
Thanks for the video it is very helpful. I have a question, the service manual and parts manual indicates the check valves are different item 24 and 25 and there’s not a part number for them. One of mine had a bad o-ring. I didn’t see or hear if you mentioned that they are different. If not different great but then where would I find a replacement valve or o-ring?
Awesome thanks so much.
nice man for the video . do you know what kind of oil do i have to put in the gearbox for murray mrd 300. im really stranded
Nice work, Bob. I have a question maybe you can answer. I had to replace the bypass rod seal and did it with the unit on the machine. No big deal. I put it back in like you showed, c-clip on and lever but now that unit does not work. So... my question is when you pull the bypass rod out, can that little piece that you held in with grease when you were putting it back together get lost? It's just weird that there's no pressure. TIA, Joe
Hi i have a question i have a Husqvarna and i noticed that when i mow on a uphill the right side transmission quits working and i have to leave it to cool off do you think that replacing the oil will help? This only happens on hills on level ground works perfect
I enjoy watching your videos. When you were referring to the bypass, is that actually called the dump valve? I've been trying to get the Skag back to moving in the neutral position if you will. I finally found the correct brake adjustment rod after being sent the dump valve rod twice now. After I gave Skag the length of the rod it's finally on it way. I changed the oil in the hydro's and the filter and oil seemed as though they have not been changed since 2006. I had to take the old screwdriver for some extra leverage on one of them. Anyway, so when I was making sure there was no air in system I noticed the left side hydro kept moving when its supposed to be in the neutral position. I have not looked the reason behind it up yet.
Hydraulics changed the earths surface worldwide. If it cost more, must be the best.
Doublewide6, just a quick question I have a Ariens Sport Zoom 1232 zero turn riding mower using the Hydro Gear transmission mfg. 2003. I did the rebuild the right unit. All when well with the reassembly, but dummy me left off the internal "Oil filter" cover. I made the discovery after it was all together. I did the process to purge the air out after a couple of cycles it still will not pressurize to turn the wheel shaft.. My question leaving off the internal oil filter cover cause it not to purge out the air in the casing?? Appreciate your comments. Thanks,
Great video, good job!!! Couple questions: when you buy a new Center Section, it comes with new motor/ pump too?? Also, can you open and fix/ tighten those By-pass valves?? You don't have to replace them?? And one more: correct torque for the cover bolts??? Thanks a lot, youtheman=))
Apparently you need to sand down the motors on a very flat piece of glass.
great video i want to ask do you work on mower shop
Can lip seal on bypass rod, top of unit be replaced w/o splitting case?
great video but loose the cap next time as it obscures what you are doing on some parts of the transmission. That being said, really appreciate the trouble you went to make and share this informative video.
I have a 2017 badboy 54inches MZ Maverick. The left transaxle is very slow. Sometimes it will not move. It has the same problem in forward and reverse. Should I replace the same thing you did? Or should I replace something else?
You seem to be pretty knowledgeable on these hydro gears, maybe you have an idea because I can’t get a good answer from anyone. I’ve got an Ariens Ikon 52, only 2 years old with 140 hours. When you’re driving straight ahead and then try to advance the left handle a little bit it will start jerking and not want to turn right?
nice job keep up the great videos.
I know im necroing this from a few years ago, but i got one of these for pretty much free and the one part I cant source is the stupid retainer cam stop for the brake lever shaft. I noticed you didnt have one on yours. i assume its to help support the aluminum on the cover. let me know what you do in that situation and have you ever had to makeshift that part. Thanks!
Love these videos. It gives more and more unqualified people the confidence to remove, open, botch, and then very quickly sell their broken transmissions to unknowing buyers as good useable units.
I have I think the 3400 pumps on a 2014 Hustler Raptor sv 60 inch and both of mine sometimes seem to go into neutral, more when going up hill. Mower only has 200 hrs and has been serviced every 100 hrs changed fluid and filters. Could mine be the check valves also? Was that a common problem? Or do I need to look into something else. Fluid that came out was always clean no shavings or anything.
Regarding the gerotor cover installation....if you install them in the wrong direction the unit will not work. Ask me how I know.... You have saved me $800 though!
how many hours had you done , before you had any problems? thanx
