Weak Tuff Torq transmission fix

[@ericpigg2689]

Good on you to make it right before you sell it. I try to do the same thing, and I will even buy them back for a full refund if they do not last a full season. Had to do it recently. Sold neighbors a Deere LA 145. Their back yard was probably too steep for that trans, and I told them that, but they liked it, and they liked my price, so it was sold. They mowed with it 6-8 times before the trans bit the dust, so I just offered to buy it back, and I am working out a deal with them. I am in the process of parting it out to recoup some of the money I have in it. I do not mind doing people right. It is a side job/hobby for me, and I have won on so many, I do not lose too much sleep over taking a loss from time to time.

[@davessmallenginerevival2847]

Thanks Eric. Some viewers say I put to much work in these mowers if I'm selling them but my thing is that I don't ever want them coming back. I won't lie it's happened a couple times but not to bad considering I've been doing this close to 20 years. Keep doing what you're doing bud

[@GardenTractorBoy]

Sometimes the wheels seem to rust solid to the shaft on the axles. This was reallly interesting, we have never had one of these apart before so thank you for going into a lot of detail. Great job fixing this, it works well

[@davessmallenginerevival2847]

Thank you Joseph. It was my 1st time trying to fix one , sure glad it worked out. Now I'm ashamed of how many I threw away in the past

[@nashguy207]

Great video Dave. You did a real nice job on this Tuff Torq. Seems to be working great!! Keep up the great videos!!

[@davessmallenginerevival2847]

Thanks Bob. It seems I'm really taking on the hard cases lately don't it. Happy 4th my friend

[@Dirtywhtboy87930]

Is that the K46 ? How long did it take to get your order of seal kit and oil? I watched Tyrell’s video last night. Might crack mine open later this year.

[@Dirtywhtboy87930]

Did you order from tuff torq, or another supplier?

[@stevoj8959]

Nothing more intimidating than diving into a transmission. Lucky it was nothing serious and it works great. Got me thinking I might do mine now to get some more jam out of it. I have over 400 hours on my Ford so I can see the filter being a little plugged. Glad you did this video. Thanks Dave. Stevo

[@davessmallenginerevival2847]

Hi Stevo. Yes it was intimidating for sure. Some day I'll have to get the courage to go into one deeper. Thanks buddy

[@jefft8138]

DITTO on right wheel removal. I heated, I oiled, I hammered, I even took two car screw drive Jack's and leveraged them between the wheel and tran housing - the entire axle shaft popped our of the transmission rather than the wheel sliding off.

[@rw3dog]

Nice job Dave. I just sent a link to your video to a friend of mine that was telling me his JD was loosing power going up hills. It’s amazing that little filter can cause the problem…

[@davessmallenginerevival2847]

Thank you very much. I've thrown a lot of hydros in the scrap pile and all I had to do was a fluid , filter change. Kind of embarrassing. I learn a lot from Tayrl fixes all. Happy 4th my friend

[@daveschooley8514]

I’ve changed the oil and filter,still won’t climb hil after 15 minutes, what’s next, repair kit?

[@nighthawk7921]

NICE VIDEO ... It is AMAZING what a NEW FILTER and NEW Fluid can do to these Tuff Torq Transaxles. The Internals of this one look exactly like the Tuff Torq K57R. on my YTH24V48 it has the Tuff Torq K57R transaxle in it and your filter system and spring setup are just like mine. I think ALL the Tuff Torq Vids Taryl has done are on the K46 Transaxle. The K57's are a little different ... Tuff Torq say they can handle 22 inch 5 lug wheels in the rear with 255/188 Nm/lb-ft axle torque, which is not alot more than the K46's, but it is more. Alot of these also will have the heat treated steel gears as well. AND one big bonus to the K57R Trans is they are ALOT faster than the K46.... at least when they are working and running correctly. :)

[@davessmallenginerevival2847]

Thanks for the info. I couldn't believe how much faster it was. The guy that bought it really liked it

[@therealdiehl4671]

A friend of mine who works on these, told me, he has fixed a number of failures caused by those caps cracking and spew fluid out. The fan blows it all around and makes a mess. The fluid gets low and the mower won't go. He replaced the cap, top of fluid, and they were back in business.

[@davessmallenginerevival2847]

I found that to be true also

[@ColinWatters]

Yes the cap on mine split. Took ages to figure out where the mess was coming from. New caps have a solid metal disc so hopefully won't happen again.

[@butler386]

Glad you got it all put back together correctly. Looks like quite a task buy you made it look relatively easy. Hope you can get some good money for it. Thanks for the video.

[@davessmallenginerevival2847]

Hello Mr butler. Thank you. Well I'm going for $900 but I'm waiting on a specific idler pulley for the deck and they just told me another 3 weeks 😡 I've already waited 2 weeks..... frustrating

[@imanenigma3348]

Thanks for the video mate, I work at a school here in Australia and our Husky has lost drive and there are a few funny noises coming from the tranny. I know it won't be as easy as yours, I'm thinking busted axle or diff gears but after watching your video we have nothing to lose, none of the mower shops were interested in buying it for parts, 500hrs and the Briggs is good as gold so with some luck I may be able to fix it. It is a second mower anyway we use for the gnarly stuff and keep our new one for the big areas. It's a Ferris and as they say "Save Ferris"

[@davessmallenginerevival2847]

Thank you , I hope the video has helped you. Not sure what the funny sounds could be , hopefully an easy fix

[@ellieprice3396]

The latest recommendation I received from a small engine shop is to use 20-50 non detergent oil when changing. It's necessary to "bleed" the transmission in many cases. It means getting the air bubbles out of the oil but I'm not sure how this is done.

[@haneyoakie14]

So clogged filter = lack of fluid flow = misbehavior of unit? Caught in time means fluid and filter change yields return to proper performance?

[@davessmallenginerevival2847]

Yes sir

[@haneyoakie14]

The Tuff in Tuff Torque refers to getting the fill cap off, not the actual toughness of the unit?

[@davessmallenginerevival2847]

And cap back on also😆

[@billsmith1770]

my jd lx176 wouldn't pull when hot . tried straight 50 weight , then trans "medic" in a can , even added restore for engines . swapped in a 5 speed , but later tore down the hydro , block sanded the surfaces you spoke of (may have gotten the wedge turned the wrong way) and put it on the shelf . the filter might well have been the original problem , but the additives definitely clogged it . i keep wondering whether i got it fixed or not . curiosity may get the better of me one day , and i'll reinstall the hydro .

[@davessmallenginerevival2847]

Hi Bill. Your trans probably works since you went through all that. Taking the pump out is intimidating for me but I'll probably try it someday. To think of all the hydros I threw in the scrap pile when all I had to do was a fluid and filter change,,, unbelievable. Happy 4th buddy

[@Dirtywhtboy87930]

The pan sealant you can use the silver from tuff torq or any RTV sealant, like blue or red, black. Must let dry partially to a skim coat then it’s ready to set the pan. Just for others FYI.

[@haneyoakie14]

Looks factory new solid now!!

[@davessmallenginerevival2847]

Thanks Tom. I'm just happy I could actually fix it

[@dakotamcneely5779]

What goes bad in a hydro gear drives? I cleaned them sanded the revolvers and center secrion smooth..mower still fails on left side after 20 min. Also put in new center section and no resolve. Does the case wear out of spec?

[@mr.astrophysics9115]

Tuff torq K46 k57 k66 are all excellent transmissions very strong but what I have seen and heard not many actually service there transmission like after 50 hours of use on a new transmission you're supposed to change the oil many don't do that and leave the brake in fluid in and just add to it..also they don't allow time to brake in the transmission when it's new and when you don't do these things expect trouble and many cases won't take very long for it to fail

[@davessmallenginerevival2847]

Most owners aren't going to do that. Some it seems change the engine oil once and then add or run it low till it seizes and wonder why

[@pierrebroccoli.9396]

With regards to the oil service, we are told that there is no need on the transmission for the life of the mower but like cars with their auto trans now days, it is good to service the oil and filter on occasion and pay no heed to the B.S. the manufacturer states. All they are interested in is you trashing your mower / car and buying anew one.

[@DIYVariety]

Turned out that you got lucky could been lot wost hey dave.bthanks bud

[@davessmallenginerevival2847]

I'd rather be lucky than good 😆

[@ColinWatters]

It can be very hard or impossible to get the wheel hubs off. Fortunately you can replace the axel oil seals without removing the hubs but you have to take the half axels out of the case. Not hard but a bit fiddly.

[@mr.astrophysics9115]

The casing is Cast Aluminum Alloy very strong and durable

[@GrampiesWorkshop]

How's she goin'? Good for you Dave to tackle this job. It sure looked like you could have ended up in serious trouble but since you had a back up Tuff Torq it was the thing to do eh. And you got it done!!!. Sure looks like a lot more speed. Nice job. Thanks for sharing and take care!!!

[@davessmallenginerevival2847]

Thanks Mike. Right, a guy could dive in farther but right now that's a little intimidating. Thank goodness I didn't have to do that. I was surprised how fast it was but when the deck goes on the weight may slow it down a little. I've been waiting for an idler pulley for the deck for 2 weeks, now they say 3 more weeks , it's frustrating

[@ab-shop]

Ciao Dave! It's a great video! Very very interesting trasmission! I don't know well how that Tractors are made, But that trasmission Is to increase the torque that arrive to the wheel? Thanks for your nice video Dave!! See you soon, ciao!! Alberto

[@davessmallenginerevival2847]

Thank you Alberto. Yes it's a hydrostatic transmission

[@Panther7108]

Hey y’all. Just came across this video, been doing some research into these hydrostatic transmissions. I have a Cub Cadet LT46 and halfway through cutting my yard, the transmission wouldn’t move in forward or reverse. I let is sit for about 20-25 minutes and I was able to take off again for a short period when it happened again. Yet again I let it sit for a bit and was finally able to finish the yard up. The mower only has 48 hours on the meter, what could the issue be?

[@davessmallenginerevival2847]

That low of hours I would think it's still under warranty but if not then I think it's not good because it's got to be a factory mistake of some kind. I don't really know what it is but it's definitely a heat problem because when it cools down it works again.

[@longracing25]

How did it take off with no priming on the bench,...or running before? You just hoped on and took off??

[@loggerjohn01]

Hey Dave. I'm finally catching up on some videos. I've had no internet all weekend. That's going to be a big project. I aways wanted to know what the inside of one of those units looked like. Better you than me doing it lol. This was interesting. Take care

Maybe silly question. How can you tell which Tuff Torq transmission you have. I've got a XT2 cub cadet. Any idea where the identification plate is on the transmission?

Should be a tag or it's also stamped, if it's a tuff torq , if not it will have different markings
