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

[@heavydownpour560]

Best instructional video I’ve ever watched. Thank you for doing such a great job. That barking dog was driving me nuts!

[@johnmcook1]

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.

[@rtaggs8178]

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.

[@ButcherNumber1]

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!

[@untame7676]

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

[@techman1274]

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.

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. 👍🏻

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.

[@robertvalente8217]

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!

[@watermanone7567]

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.

[@CincinnatiDJL]

How many hours on your mower before you notice a leak?

[@hooklinetinker9680]

Problem turned out to be the input shaft bearing. 630 hours

[@michaelcolford6817]

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 KZbin 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?

[@johnmills5398]

Enjoyed the video and the presentation. You're an excellent mechanic and do (high) quality work. Thank you!

[@daniellee3791]

When removing the check plugs, it is vital that you put them back where they came from. That’s a vital step you skipped.

[@williamnewsome5169]

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?

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.

[@dpgoodall]

Nice job! That’s one of the more complicated projects I’ve seen you tackle!

[@staind288]

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

[@416dl]

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.

[@iconiccreations2492]

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.

[@LegendLength]

try belt issue or tensioner

[@markcoplon1773]

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,

[@lccurtis6548]

I don’t know if you check the comments on a post this old I hope so. I have a ZT 2800. It failed on one side. I took it apart and found the center section completely destroyed. The motor block springs broke into pieces and ruined center section. I replaced it and the piston blocks. Put it together and ran like a champ for 5 minutes now it does nothing what could I have done wrong?

[@aleblanc3547]

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!!

[@tonym6920]

You are one heck of a mechanic, great job!

[@billyrayband]

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.

Great video from start to finish. I have the exact model with the same issue . Makes me wanna tackle the problem Myself ! Thanks .

[@duncang01]

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.

[@Smalltechguy]

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.

[@jasonruch3529]

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😊

[@2491kridge]

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?

[@jrx2662]

my left side does not move front or back, but when I lift it up off the ground, then it moves front and back, do you have any idea's what it could be? thanks

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?

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!!!

[@jerryf2426]

Aircraft Mechanic> Did you know that snap-rings should only be installed with the sharp-edged side toward the direction of removal. When stamped out there is a sharp-edged side (the down side when stamped ) AND THE ROUNDED EDGED side ( the side the stamp strikes).

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

[@rclayton80]

I'm hung up on the bypass pin. I can't see what it is or where it goes.

[@redblue40rc33]

It bypass's the transaxxle preventing the tires spinning.... Located on the rear, L shaped rods with a safety clip....pull both bypass rods outward....if your facing your rear of mower, look down on both sides and they be right there kinda close to tires ......

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?

[@catfish307]

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.
