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.

Definitely the best how too video on KZbin. For anyone doing this I found that the perfect thing to pull those seals out is just a little 1 gallon paint can opener.

[@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.

[@joeyelswick1796]

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. 👍🏻

[@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!

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

[@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

A great video. I just don't know how you can keep track of where all the parts go. A good job done.

[@nickyborrisino]

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.

[@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!

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!

[@sixstring7855]

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.

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?

[@jfssparky]

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

[@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?

[@chrisstaffords5569]

You just saved me hundreds of dollars. Thank you

[@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

[@bradthebad01]

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.

[@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!!

Good video but for the few segments off camera that lacked the visuals to see where parts were going back. I know it’s hard to do these and not get in the cameras way, but for the novice that needs to see the details it would help if you were a little more cognizant of this detail. Otherwise great instruction! 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.

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 ......

[@catfish307]

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.

[@larryprater1022]

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.

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?

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.
