I think that guy is the "real" spawn of Svengoolie...
My neighbor gave me a John Deere L128. The trans leaks fluid. John Deere told here to buy a new one. Hopefully it's the seals. Wish me luck.
I`ve been a mechanic for 43 years and never heard of a roll pin punch. Learn something every day.
You can make some outa old punches if you have some.
Must be a Canadian thing.
We are a family of machinists, mechanics, and engineers in Ohio.
No one had ever heard of one.
A few will be made shortly!
Proper terminology: Pins=Pistons, Little washer=Swash Plate, Thing The Little Pins Are In=Barrel, It's basically a hydraulic piston pump with a piston motor for the output with two cross port relief valves to make up a hydrostatic transmission. That you for this video. I was just looking for fluid change procedures and came across your video. It seems Huskvarna went out of their way to make these mowers as close to disposable as possible but where there's a will there's always away. Thanks again.
I don’t even own a Tuff Torq but I watched the entire video. I just like to watch Taryl’s instructive and entertaining videos. 👍
Same here ☺️ but it was a great video 👍
I love Taryl's videos. He explains every step of the process, taking nothing for granted. His videos are exceptional.
Is butt-head of your distant cousin?
I'm glad that this transmission can be completely rebuilt, and not a throwaway.
JUST finished doing this on my K46 from a Husqvarna 20/42. Took 3 years for it to completely die on me so i picked up the kit out of the US because NOT ONE DEALER IN MANITOBA could source the part number i needed. Took 3 weeks to get here and $750 CDN later on the rebuild kit and it works! Took a bit to get it all bled out, but just cut 2 acres with it and it will actually go up a slight incline without issue now. My symptoms were a nasty whine from the tranny as well as no power at all. Just crawled like a turtle and then died. Changed the drive belt multiple times thinking that was the problem and no joy. It was always the pump, motor and case. I'm pretty mechanically savy, but this video certainly helped me. Thx Taryl
Taryl this video is a GOLD MINE of knowledge!!....................THANK YOU FOR SHARING YOUR KNOWLEDGE!
Taryl Makes The Best Video's of Anyone
So input pulley and belt, drive the drive pump with the springs and pump plungers, they bear on the swash plate. The Swash plate is sprung to a flat position meaning no pumping, if you rock the swash plate either way the plungers start to stroke, pumping oil one way or the other for forward or reverse, the amount of tilt on the plate varies the amount of oil the drive pump delivers. This feeds the corresponding plungers in the output pump driving the stack of gears going to the differential. The output pump plungers drive against the ramp which can be put one way or the other to reverse operation of controls. Pin pushes valve faces apart to provide a positive neutral. Filter is on suction from sump. Interesting stuff thanks Taryl. Seems like changing oil and filter on a regular basis saves the day in most equipment. The two dampers for forward and reverse selection initially dampen the transmission take up by allowing some of the oil going to the output pump to press the piston back against spring as the rest of the oil heads to the output pump driving section, causing a slower take up. Should wear gloves oil is not good on hands long term, so should I😀
Great video Taryl. The trans I rebuilt is now working perfectly. Instead of buying a rebuild kit for £300, I had both rotors machined, removed approx 5 thousands of an inch from each one. I then cleaned out the crankcase thoroughly with petrol, reassembled, added fresh oil, refitted trans to the mower (a Countax) and it works a treat. Many thanks from England😊👍
which specific piece do you machine? Is it the round "motor" that holds the five pistons?
@@bwp253 hiya, yes, what happens is the surfaces becomes scored, these micro grooves cause pressure drop as the oil squeezes out through the grooves. Taryl shows this in the video.
Taryl, love your humor! If you take it down to that level, to save a bunch of cash, you can block sand the 4 pump and motor surfaces with 1500 grit wet sand paper using the motor/pump rotors as the blocks, only takes a few minutes each to flatten and refresh both surfaces. It doesn't take much grooving (.005" or less) of those surfaces to lose pressure.
have you tried this successfully? I saw it on another video and was wondering if the surface is planar enough at the end. Trying to save the $400+ that a rebuilding kit cost!
@@bwp253 Absolutely, i have a granite surface plate I use the edge of. Just cut in half and laid the 1500 grit on the plate, kept spraying plate and paper with water and worked the parts back and forth with even pressure until all groves were gone. had to remove the locating dowel pin from the aluminum body to get more room to work it.
PS that isn't my post above with my name on it, I posted a much longer step by step procedure describing how I do it from removal, disassembly, resurfacing, reassembly and re-installation, don't know what happened to it YT is screwy sometimes.
@@bwp253 Found that post, see below.
Taryl is still the greatest, thanks Lewis
The Sound Effects are brilliant and help me to better pay attention to this video. I'm going to nominate you for The Academy Award for Best Sound!
You deserve your own TV show man that's how good I think you are
Thumbs up thank you Tyrell. I really needed help with that one and very entertaining. Not boring at all.🎉
This is the best ''How to video'' on TH-cam......
I don't own a riding mower (yet). I don't plan on rebuilding the trans (ever. Hopefully), But at 5am on a Saturday morning I watched this entire video because Taryl is informative and entertaining!!! Going back to bed now!
I had a john deere D110 i purchased for $75.00 trans would not move not even in neutral. I pulled the transmission out after watching Taryls video and found a $4.00 bearing demolished. Replaced the bearing and the trans worked great! Thanks for the great video!
Taryl, for turning the pump to prome it, I cut a small 3 in section of 1/2" copper pipe then slotted each end and used a 10 mm socket to drive it with my drill driver. Secured the pipe ends with worm gear clamps. Like your videos. Thanks
As a Mechanic for over 40 year's it's easy to tell Teryl is a very seasoned Mechanic.
I had an oil leak in my JD D125, due to a rock being thrown up from the blades. It caused a graze with a tiny hole in the aluminium casing below the diff section. I contacted my JD dealer who said, the only way to repair it was a replacement Tuff Torq transaxle at Au$975.00. Thanks to Taryl's video series and a tube (actually two tubes as it's an epoxy mix) of JB Weld, the whole job took less than an hour and cost less than Au$20.00. I also fashioned a steel 'bash plate' to go under the transaxle, so, hopefully, it won't happen again. Thanks from the real deep south, South Australia, there ain't nothing souther than us.
Seeing how hydro transmissions work was really interesting.
Easy To Work On Once You Do One Wouter
VERY, VERY GOOD VIDEO , WELL EXPLAINED AND CLEAR FILMING . THANKS FOR POSTING THIS.
Thanks Taryl...great video and a big help when doing this job.
This is one of your very best videos. These hydrostatic transmissions are really not that bad to service if you see a thorough demonstration of the servicing procedure. I've watched two other videos prior to this one and yours is really excellent, covering all the details and explaining some of the important details of the design of the parts and how to avoid errors in the reassembly procedure. These transmissions are really expensive to replace (practically the cost of the tractor) so servicing one that is working but no longer delivering the original amount of torque and speed is going to save people a lot of money if they can spend the time to do the rebuild.
I was just given a Cub Cadet GTX 1054 (2011 model) that I now know how to service. Probably the best service film I've seen ! Thanks from BERMUDA 32N64W.
A great tutorial
My john deere L110 (15 years old) has a new lease on life
Thanks
I could watch all day ,you are clever also funny
Thanks for the video! I put this project off for a few years since I burned up the K46 in my JD LA175 from pulling an aerator. It really wasn't that bad to do and people told me I was nuts for taking it apart. It just takes patience. I kept thinking what a waste it would be to just scrap the tractor with a good engine in it. Well, it's back in and no longer wanting to lay down on me after a half hour of use. Once again, thanks!
Daryl you should have your own TV show so you can show us how to work on our lawn mowers a lot better I think you're a great mechanic
Ty for taking your time to teach me this I wanna get into small gas engine transmissions
Taryl is the best and I do believe he CAN fix all!!!
This was great. The acting, script and comedy were excellent. You Guys are good actors.
It’s called a metal block ..... who cares what it’s called..... that’s where it goes..... that’s all you need to know… Priceless! :)
You dont need to replace the revolvers and The center case if them has groves. Just buy some wet sandpaper ( 320-1200 grit on the revolvers, 400-1200 om the case). A sealkit, breakcleaner, Some new motoroil and a piece of glass (minimum 4-5mm thick). Lay the glass on a surface that dont flex and dosent have any groves and etc. Place the sandpaper on the glass with some oil on. Start with the revolvers and move them in 8’s. Start with 320 grit and end with the 1200 grit. Wash them clean with brakecleaner. Do the same with the Housing but start with 400 if its deap groves. If its just small groves start with 600 grit. If you dont can sand in groves just move back and forth. Inspect all the springs in the revolvers. Inspect the pins on the revolvers so them dosent have any holes on the top. Reacemble everything again. Fill it with right oil and Mowe your lawn!
Have Done this about ten times with good result.
Sorry for my bad english. Im from Sweden and misses som english lessons in school🙄
I done this with lapping compound and wd40. When you get to a mirror finish, one light swipe with wet scotch bright to give it the smallest crosshatch.
Great video! Helped me rebuild my Husqvarna hydro. But I came across an idea that helped me with the reassembly.
I put a rubber band around the spring-loaded pistons before installing the motor and pump blocks to hold them from falling out. After installing, I used some hemostats to hold the rubber band, then used a pair of scissors to cut the rubber band and just pulled it out. Simple and makes the job much easier. If you don't have hemostats you could use a pair of needle nose pliers.
I really enjoyed watching this one Tayrl/Junior/Crew.I guess Amsoil has really saved my K-66 from leaking seals.I put in Amsoils Hydro/trans oil,5W-30.
I done this just after break in.
My LX-288 is 20 years old and not a single leak what-so-ever,mowing 15 acres of lawn every week.
That's cause it's 20 years buy a new one and let's talk in 5-years.
@@edgenet1 My newest tractor is 10 years newer then my LX-288.
In the summer of 2010,I bought a X-534 with the K-72 C in it.
I've done the same thing to this one,right after break in,I installed Amsoils 5W-30 hydro/trans.oil in it.
After using this tractor for 10 years,no leaks at all.
the sound effects on this channel are a great touch! i love the "boing" every time he says spring.
I like it when the seal barks
it was annoying
I’ve watched all your vids. In my opinion this is your best one. Very informative details such as the roll pin punch, rag trick and the seal theory. Impressed with your knowledge and the support from Tuff Torq. Thank you Taryl and co.
This is an awesome video. It’s so much fun to watch somebody that really knows what the hell they’re doing. I love it. I had to do this very same thing to the transmission in my LX279 about four years ago and I did have a video on TH-cam from some guy showing how to do it but it wasn’t as good as this video. I wish I had this video back then. Pressure washing the transmission before you crack it open is a must, it’s so nice to have everything clean when you’re taking it apart
Great respect for both the design engineers and the service personnel for jobs well done.
Your repair job was quick, serious, straight to the point and thoroughly captivating to say the least. I know you're having fun doing it! Good luck.🔧
Thank you for all of your lessons you are a wealth of knowledge, I am in my first year of trying to be a small engine mechanic ,I do struggle with the electrical part of the small engines i cant thank you enough for all of the efforts you do, keep making the short films they really make the day feel good
Great job and video. Everytime I see parts...it reminds me of people behind it. Machinists, draftsmen, engineers, inspectors, machinery.🙂
Kudos from Eliminator Performance Small Engine Repair in Ontario, Canada. One of the best well organised and edited transmission rebuild videos we have seen. Keep up the great videos and keep safe and healthy.
More mysteries of the order revealed. I have rebuilt 2 in the past and it is intimidating, but do able. Now we have a how-to video to study before the operation,
and keep open as we go!
I just realised its 3:30 in the morning.. I been watching Taryl's videos for 6 hours straight😲🧐. Your videos are hilarious and informative.
Agree just dropped my transmission for a broken axle. No fear with this guy.
Thank you Taryl, This is the only video i have found that explains why the mowers forward and reverse are backwards. Thumbs up
great transmission video, when you open a transmission like this you better know what you ar doing, AND TARYL KNOWS HOW TO PUT IT TOGETHER AGAIN
Thanks Taryl, this was the best video I've seen on the Tuff Torq. Awesome job there buddy Now! Now to find my model # on mine.
So glad you explained this rebuild so well , thank you.
It is amazing to see you open up that clockwork nightmare, explain it in gut wrenching detail and reassemble it into a function state. Thanks for your efforts, and may I NEVER have to do that to my mower lol!
just want to say you are a great mechanic I am retired now and used to rebuild mack transmissions and rear diffs it is a pleasure to watch you work.
TH-cam's informational highway just went to the next level. Great video.

THANKS TARYL , youre my no 1 go to when i need to see how to repair a riding mower ,and (THERE IS MY DINNER) yes iam subscribed ole friend
Outstanding Tuff-Torq rebuild video! Thank you for sharing!
I'm glad I have sunstrand in my 20 year old simplicity! So far It's been bullet proof! Great video by the way!
Brilliant video loved every minute of it gives me the plus learning at the same time, thank you❤️👀👀👀👀👀👀👀👀👀👀👀👀👀👀👀👀👀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Very interesting video. You should be teaching these high school kids a good trade like small engine repair! Thanks !
Very Helpful!!! My K58B was a little different, but most everything applied to it except extra rotor pump on bottom of Hydraulic pump, and the small roll pins that have to be removed and reused to locate it. Thank you very much for your video. Most folks dont realize just how much effort goes into making a video like this.
Hey Taryl ! Remember when you first saw "Deliverance" wasn't that The Best Love story You ever saw?
Love your videos!!
Thanks for the info! Dude you are very neat and organized!!! I like the way that you clean off the crud and junk before you open a system up for service. I see people just open them up with dirt and all kinds of junk around it. I’m just a regular guy and I like to work on my own equipment. I’ve gotten burned letting strangers and shops work on my stuff. You normally don’t find out until you get into it yourself. I take pride in my work. Done right done once. I had my mower tipped up and leaked some trans fluid out. I think I need to add some fluid to mine. Gonna start that task right now. Gotta figure out where the fill line is on mine. I saw the fill cap. I have a Cub Cadet SLT1550. Thanks again.
This video is just amazing. Your detail and teaching ability is unbelievably good 👍
...and he hollers at people like Joe Biden...
More leaks than the supreme court...
Thanks for this great presentation and great what if scenarios. Plus imparting your general knowledge!
Another job well done. Sometimes I save some time & money by purchasing a junk mower with the same trans and just swap. There are lots of mowers with rusted out decks that drive just fine and most people are willing to give them away or for very cheap. Not taking anything away from the excellent job you did, just giving an alternative. Keep up the great work.
Taryl, this video is pure gold. Bravo, bloody good show ole chap.
Thank you great breakdown. I have a hydraulic system on my narrow boat (UK)and you have given light on something I knew nothing about.
Cheers Bud.
DIG IT OUT!!
That's what she said!! 🤣🤣👏👏
Thanks for the video. I just had a broken axle shaft but your video made it much easier to fix..and some valuable tips when reassembling it.
Too easy to watch great videos and excellent information.
very well explained Taryl, Thanks from Canada! Awesome vid gives me enough info to do my own Tuff Torq transmission
Taryl thanks so much for the video made rebuilding the k46 a snap
Man, that was an interesting and informative video. Refreshing to find a company like Tuff-Torq that sells parts to fix their stuff with!
Best movie with action, suspense and drama
You're a smart guy Taryl. Thanks for this viewing of the Hydrostatic Transmission, first time I seen the insides. Great table and stand you have friend. Surgeon told me how many individuals get Carpal Tunnel by using your hands as a hammer like you did to loosen that one bolt. Be care with that bud.
Appreciate the video! Could not have repaired it without this info!
Congrats you guys are almost at a 100000 subscribers I've been watching since the beginning love it keep up the great work
Thank you for taking your time to show us hotdogs how to do the job right I love all yer vids be safe
Taryl, you got some knowledge and know-how there buddy. I can watch this even though I would not attempt to rebuild one.
Great idea puttn that tape on there. U are the boss when it comes to mechanical aptitude and ingenuity.. vids are hilarious
I appreciate the video, not sure if I'll ever own or work on a hydrostatic transmission but it's still interesting to watch and learn.
If you buy a new lawn mower best to take the rear wheels off and put anti sieve on the axle in case you need to take the wheels off later. Saves a ton of work if you have to take them off later. Just a tip
Applies to truck hubs as well. We had brand new 8 wheelers with brake drums. First time hubs came off was 24 weeks some needed smashing of, the extractor bolts would just pull their threads. When new pull off all hubs and copper slip mating surfaces lightly, saves time and money down the line. Funny how things are the same across all fields we can all learn.
Finally! I have been trying to find some info on this transmission and having no luck. John deere says no repair but we will sell you a brand-new one for 1100 dollars.
Was slow to move in reverse and then just stopped while cutting in forward. Could feel it slightly load up when switching forward to reverse and back but no locomotion.
Thanks for this👍
Did you get it fixed?
I have an inlaw that uses the very same dentist,great guy excellent prices....thanks for the info/video bud
***NOTE**** The direction of that swash plate on the drive side can vary among the different K46 models. Early 46BC and 46BD models swash plates are installed in the opposite direction to the model shown in the video. You can confirm this by looking at the parts diagrams on the tuff torq website. Also keep in mind the diagram is "up side down" relative to how most would service the trans. Best to take a photo of yours before the tear down. That's what saved me.
Another very informative video Taryl. Your a wizard at giving out useful tips. Pity your not doing some car maintenance.
Where you goin, City Boy???
I'm going to watch Taryl do yet another fix I wouldn't ever attempt.
Great videos, man!
I learned something and thanks! have gone through three of these with success, maybe because I also ordered what Sundstrand calls slip rings for both set of pistons. It will run you 1995 dollars $55 bucks
I live 3 minutes from the Tuff Torq factory in Morristown. Had no idea they made these transmissions.
Good video Taryl thanks now I know why mine doesn’t want to go backwards some times. I replaced the oil and that helped a lot but still acts up on some of my hills (small) sometimes. Excellent video!
on some tractors, you can get a buildup of dead grass that keep the pedal, or lever, from going all of the way to engagement.
GREAT video that helped me alot. Thank you. Have you ever replaced the outer axle bushings? I did. I used a long 3/8 steel rod to drive out the old bushings from the inside and a large drill press as a press with flat washers of the correct thickness and diameter to press the new bushings in to the correct depth in 3 steps. The 1st step was to press the bushing in to the same depth as the outside of the transaxle housing. The 2nd step installed the bushing to the same depth as the bottom of the seal pocket. The 3rd step pressed the bushing another 0.0875 to the correct depth in the transaxle housing. I froze the bushings for a couple of days before I pressed them in and was surprised how easy the bushings were to press in. I had everything ready before I took the bushings out of the freezer one at a time to press them in. I used micrometers to measure the diameter and thickness of the flat washers. I hope this information is useful to anybody who replaces Tuff Torq transaxle outer axle bushings.
This is a really well done video. Clear and concise. The details are what will save the first time home repairman from making mistakes. SALUTE.
There is a guy selling the whole transaxle unit labeled as a K66 for $2000! He started out selling them for $800 about 7 years ago but now it's up to 2K.
This will hopefully save my friend from spending way more than he needs to. With a bit of luck the seal and filter kit will get his running again. I have it at my house right now. Sucking out the oil and refilling it didn't fix it. I suspect the filter is clogged.
My friend just got a brand new John Deere E130 for less then $2000
great video on this transmission, I've seen other brand tractors like husky and people say there hydrostatic too but there not this style is because it does have a hydraulic reservoir. Thanks for the video.
i rebuilt one of these last year it was a learning curve. got it running but the owner wouldn't buy a new belt. so they took it to a professional shop and he charged them100 bucks to install a new belt and it still runs great.
This video is invaluable.
Taryl a empty 5 gal bucket works just as well!! Perfect fit!! Nice video's you put out!!
Great job Taryl. Keep em coming!
You guys are the best
Hey Taryl, great video very helpful thanks.
Nice job! Enjoyed that, thanks all 👍
