Here is a quick video showing the torque converter setup install. You can find these TAV torque converters all over the internet. They are cheap and easy to install. If you are going to be using your mini bike or go kart a lot or you don't want to take it apart very often then I would suggest getting a Comet brand torque converter. Yest they are more expensive but worth it in the long run. Do you want a Harbor Freight tool or Milwaukee! If you look carefully you'll get a sneak preview of another yerf dog go kart i'm restoring and rebuilding.
Dude, thanks so much for this how to. Very thorough and attentive to detail. I also love your different angles showing how it works.
Glad it was helpful!
@@-DIYPRO- Thanks again. I hope you enjoy the holidays and new year.
Cool to see it working, I have be aware of how they work for a while but never actually saw it working outside of a vehicle.
I never knew the sprocket could be placed on the other side. Thank you you creating this video.
Thats how mine are or was mine im giving both away to someone more interested 11 hp tecushas ¿ not sure if spelking is correct but they both go about 32 33 mph will climb 40* hill. Not at 32 it will leave the ground dont want that. I put aggie tires on the front and thats when i started breaking ft end stuff. Then i lost the 75 acers to ride on and welp someobe else can have some fun. I keeping 1 no shocks tho . Bad on the old bac.
Thanks so much. Father son project was successful 1st shot since we were able to double check our work through your video.
Awesome!
Thank you so much for doing this vid. It really helped me out even though I'm mechanically inclined, it was my first TAV install and I had zero instructions about how everything went together. Installed on my BT200X.
this was a great video especially noting a separation between 3/4" and 1" diameter of motor shaft so people don't order the wrong torque converter.
Fantastic video! Thanks for showing how this goes together and how it works.
Thanks
GREAT video showing a torque converter in action!
Thank you buddy. My belt was on backwards and I didn’t even realize it could be
No, Honda did not sponsor this video! Not that they would anyway, didn't realize how clear of an advertisement shot I gave them at the end.
My kids go kart has one and when ur climbing hills the belt slips and way of adjusting it ?
How can we put sprockets on the opposite side of CVT box??
This looks more like a continuously variable transmission than a torque converter, but it’s interesting to see it on an engine as small as this! It would make a killer go kart installation.
cvt/torque converter = same thing
@@DWinnie67 its not the same thing, cvt can come with clutches as well instead of a torque converter
@@vijayvjn6874 true, a cvt can serve as a safe idle clutch
@@johns3655 i didn't mean the forward clutch that new cvt have that are used to disconnect the torque converter at idle or a stop, there is nothing stopping cvt to have traditional clutches instead of a torque converter, calling an apple a red orange just because it fits your mental model of how something ought to work doesn't make it so
@auntysocialist I was on the Baja SAE Team at my university, and even there, we called it a CVT. We even had one person on the specializing in CVT tuning!
Thank you. This IS the type I am installing. I had doubts until I watched you.
Glad it helped.
Bought a new 40 series clutch and driven clutch, in which I mounted onto a tav gearbox , I needed to change to a reverse spring on the driven clutch ,I had a hell of a time getting it apart after I removed the spring clip.I noticed that the bores were a little rough ,and the parts were sticking on the shaft, so I took 180 sandpaper and cleaned it up .Now all the parts slide along the shaft freely ,I'm running a 14hp subaru engine.
Right on.
Good video. Straight to the point no extra talking I am putting one on tomorrow and should just be able to follow it step by step basically
Use the rear pulley to turn a transmission. Back in 1969 they had a scooter called the Tule Trooper mountain bike and it had a 2-speed gearbox. It could either crawl up a tree or do 50 mile an hour.
I'd love to do that on my go kart.

Very nice video! Clear picture and audio. Installing my torque converter next week. Thank you!
Have fun!
WATCHED IT AND LEFT YOU LIKE NUMBER ONE !
Excellent video. Nice clear instructions with good video. Thanks!
I'm just an old mechanic wishing I was still working and having fun like you guys.
One thing I noticed is that you all are calling this a Torque Converter.
I may be out of date but a torque converter is more like a fluid coupling.
This is more like THE CONSTANTLY VARIABLE TRANSMISSION (CVT), it changes it's shape to achieve different speeds.
This transmission is used in some Mazda vehicles, I just don't understand how the term Torque Converter was applied to this.
Little things that get me lol. Next thing you know they'll be calling it Pound Feet instead of Foot pounds
www.mazdavictoria.com/what-is-cvt/
You are definitely a car guy. They all say the same thing and I totally agree but I wasn't the one who came up with the name. For some reason someone called these CVTs torque converters and it stuck with the go kart guys.
@@-DIYPRO- Oh yeah, definitely not criticizing you. I just happened to be watching your channel. I subscribed by the way. I like what you do and enjoy watching. Keep up the great work.
@@OneCupOfCoffee204 a good way to think about it is how the word is used in application, if applied in a small vehicle = torque converter, if applied in a full size car its a CVT. You wouldnt put a fullsize CVT in a gokart but you would but a Torque converter in there.
I just rotated mine to the next 4 holes so I didn't have to cut any of the casing away. I did have to raise my motor mount, which took some time with cutting and welding. I'm pretty sure your idea would be quicker, though.
Hey if it works, right!
Thanks for making this video, please make more.
Thanks for making this video and answering the question that I needed placement of the sprocket can I choose both sides awesome
Right on, thanks!
nice review love it keep up the good work
Thanks!
Good afternoon. What size socket is the driven pulley lock nut? Thanks.
Interesting. Thanks for the video
Thanks!
Great vid bro. Dang i remember my 1st interaction with ine of these.. seemed like the future from my days playin w mini bikes. But that 3 wheeler.. dayum..
سمعت عشرين فيديو ما فهمتها الا من الفيديو ده......ممتاز
What happened to the small brass bushing for neutral position? This kit didn’t come with it? I’ve heard of people using copper pipe to make new bushings.
Thanks for the help. Been meaning to buy one of these for my mini bike predator 212 but never understood how they worked.
Any time!
Will not work on a Colman no frame clearance
The belt on my torque converter keeps ripping. Ill try this out and see if this works. Thanks!
Let us know how it turned out and if it helped.
You have missed the most important part. The brass collar that goes over the engine shaft pulley, so when you're idling the belt isn't wearing on the spinning pulley, The brass collar that goes over it actually keeps the belt and brass collar from spinning until you give it throttle.
I thought the same thing but the 1" shaft and 40 series I guess don't have them.
@@-DIYPRO- that sucks, Yeah that is the important part. I would definitely go out and try to find a collar big enough to fit loosely over that so you don't wear a spot in your belt at idle. This is good information though. I'll keep this in mind if I ever decide to pull the trigger on a 40
ty for video also you mentioned locating the sprocket on the back sid..do i need a different sprocket as i have pulled my hair out trying to see how please enlighten me
You use the same sprocket. When taken off you can slide it through the bore and put it on the back side. Hope that makes sense.
@@-DIYPRO- ty you for replying and yes I have tried this and there is a section that is like a hair thicker in diameter which stops the sprocket from sliding all the way back to the opposite end also the slot is is not machine all the way to the end. Do you have a link or maybe a video or something that shows this please?? I as well as about a million others would be eternally grateful!! Take care Sir and thanks again
I noticed most belts go onto a brass fitting I got the same one you got but you don’t have a brass fitting mine didn’t come with one do I need one on this product????
I thought the same thing and did some research. What I found out is the 1" borre do NOT have the brass bushing. Doesn't make sense but the nice comets and these cheap China ones don't come with them when 1" over bigger.
What type of torque converter is this? I bought one and you cannot put the sprocket on the back side because there is a step down in the driven shaft and it is not channeled all the way across for the key. But I need a shaft that will do that for the setup I am trying to put on a mini quad.
Use an angle grinder and adjust the key where you need
you gotta add the bronze bushing under the belt on the driver pulley! you gonna burn that belt pretty quick
Actually the 1" shafts don't have the bushing nor the 40 series, in case anyone cared about those too.
I thought the same thing and called a bunch of manufactures.
Mech Masters may i ask why? I have a 1" and was having issues with the bronze bushing. I removed it and now the belt locks up on the rear drive pulley. Any suggestions?
@@matthewpayment5224 the bronze bushing is to keep the belt from engaging until you want it to. if you dont have it its always going to want to drive
Very nice!!! Do you know what gear ratio range this torque converter has? Thank you.
I’m glad to know the sprocket can go on the back side because set up won’t allow for the normal way. My question is, will the pulleys not be aligned when the sprocket is on the back causing the belt to wear quickly?
It will still be aligned. You'll be good.
There's no keyway on back portion of the Jack shaft so the gear can't go on back side. The keyway only cut to fit from the backing plate to the threads.
@@212mafia-jernigan6 can you flip the shaft to the other side? I don't have mine anymore but I know mine when on both sides.
What size nut goes on after the driven pulley? I bought a used Coleman ct200u with a torguq converter but that nut is missing.
Sorry, sold the cart so I don't have it anymore. You can always measure the diameter and thread count then pick up that size, one bigger and one smaller since I always choose wrong!
Good product placement!
Me abrió los ojos a buscar ese producto para acoplar a un motor estacionario kholeman diesel para un modesto proyecto.
saludos desde peru
Totally agree.
according too the instuction the keyway washer goes on the outside of the gear not the inside!! but I'm am learnig with you !! Thankyou
Right on!
A+ video tutorial. Thank you so much.!!
You can avoid grinding if you raise the engine by putting 1” risers underneath.
The interference was with the engine oil fill.
@@-DIYPRO- yes if you raise the base you can rotate the CVT plate to avoid the engine. I have done that to multiple mini bikes and go karts. In the case of some mini bikes you might need to remove the stock gas tank which provides a perfect excuse to install a real motorcycle gas tank that looks way better.
@@bodhranlowd I see what you are saying. I'll have to try that next time.
How do these achieve a state of neutral. The centrifugal clutch to me make sense but cvt torque converters not so much.
What things should be considered in torque converter maintenance?
If you are carful you can ad a drop of oil to the spring but most people put too much and it gets on the pulleys, just slips after that. I suggest nothing.
I would like to know exactly what torque converter that is . In my application I need to put the 12 tooth sprocket out behind the engine where u said it could b placed
TY for this vid. Did yours not come with a brass bushing to go under the belt on the driver? I've read that it will help the longevity of the belt.
I did a bit of research because I thought mine was missing but it turns out that on the 1" shafts they don't have them. Even thought this isn't a comet I called them and asked if their 1" shafts come with them and theirs don't as well. Don't understand it because you'd think it is almost a necessity.
How do you put the sprocket on the other side? I have the same tav2 30 series knock off and i can't get it to work.
Have the same question. Assuming you need a different jackshaft but i can't find anything online.
Great video
Thanks!
Very nice video. Tks for doing it. My piece of equipment won't stall. Even at the lowest RPMs, if it's in gear, it's trying to go. What have I done wrong?
Need brass collar for drive pulley
You didn’t have to use any washers to shim the drive pulley?
Are you sure that you got the correct torque on those bolts.
And it looks like you need another spacer on that front pully.
Or take a spacer off the driven one.
Yep, 1/4 turn past max!
THANK YOU!!!
Hey Mech Master! Thank you for all the great videos! I'm wondering, I've heard that the Chinese have like 10 different qualities for every part they make... Have you had experience with different brand clone torque converters? And have you used a Comet and gotten a feel for how much better those are and why? Trying to determine what to get. Is there a clone torque converter you recommend? I see on amazon the two top ones are a Moosun and a Mophorn. Thanks!
I ordered a Moosun the other day for my Manco. I have a buddy that uses them as well. He says to order 3 to make 1 good one and send the other 2 back. LOL
What size is that belt?
Very good video, 👍🏼
So I got one but I don’t need the sprocket in the back what should I do ??
How are you transmitting the torque to the axle? Do you have the axle directly connected to the driven pulley? If you don't need it you still install it and just let it spin, won't hurt anything.
@@-DIYPRO- yeah that’s what I ended up doing it’s turned out just fine thanks for getting back to me
Hey, I was wondering if someone makes a manual clutch like that ?
Somthing where you can keep in a low ratio. Keep the engine at max RPM . Let out the clutch manually
Is the key washer between the plate and sprocket absolutely necessary?
Absolutely, probably not. Is there a reason why you don't want to put it on?
My chain rubs the pulley, or whatever you want to call it, so, instead of placing the key washer between the plate and sprocket, I have placed two washers on the left side of the sprocket and the pulley, moving the sprocket and chain to the right just enough to clear the pulley, but someone told me if I don’t use the key washer on the right. It’ll destroy the bearing.
Well done, thank you!
How do you take the rear pulley off the axle ?
The one end has a snap ring. the other is a nut so it "should" slide off if you take off one end.
Very good vidio.
Thanks
Blackhorse Racing makes the only decent inexpensive ones.
I have a 40 that never skips a beat and just got a 30 series from them also.
These things need to be perfectly staight and have the belt on the correct way.
Not implying the uploader did this, just leaving the advice since that is at least 90% of the time the problem people have.
Can the torque converter be installed with the driven side on the front so you don't have to hog out the converter to fit?
Yes.
Whats the difference in hp with a clutch and torque converter. Faster take off or more high end?
These you get more low end torque. You can always switch sprockets around for what you're looking for. For example you could put this on a Go-Kart with a smaller count tooth sprocket on your axle and I would give you the low-end torque to get up and go and higher speed.
I'm having trouble finding a torque converter that I can move the chain sprocket to the outside position. Do you have the name of yours and where did you buy it.
Once the chain is hooked to the sprocket what keeps the bike from going into motion? It appears that the belt is always spinning the sprocket even at idle.
When there is weight on the machine the belt spins on the pulley until reved up.
As the output shaft spins, it engages a clutch in the driver spindle at a certain RPM, if under a minimum RPM (Idling) it wont engage the driven pully (the back spindle the belt drives which is also attached to the chain sprocket and wheel)
my torque converter is hard to bloom, how can I make the performance of the torque converter better?
There are springs that can wear out. Kart Fab on youtube has done some good rebuilding videos.
Did you not have to touque the bolts attaching to the engine?
Is there a easy way to trouble shoot it not opening up for the second “speed”
Motor not powerful enough for the application. AKA ur too fat or ur buggy/vech is too fat. Or you bought the series 40 converter meant for higher power small motors 8hp+
Thanks
With a 40 chain you'll need to modify it by removing the bottom we ear off the back plate
Good to know.
What does this do exactly? Keep the engine spinning while coming to a full stop?
Exactly, it allows the karts to be stopped and the engine to still ideal.
@@-DIYPRO- Probably so the engine does burn itself out? Wonder if these are needed on the electric motors?
What’s the sizing on the belt??
Where can I get a torque converter for a 16 hp engine. 1 3/4 shaft
You'll need to look more for a CVT that they put on snowmobiles.
Is there a way you could tell me the distance between the two pulleys? From center of engine crankshaft to center of the Jack shaft ?
Sorry someone else will have to chime in if they have a 1 in bore size because this engine I'd put on a go-kart and don't have it anymore.
my motor's output shaft length is short, how can I solve my problem.
At a idle the belt is spinning, does this mean it would drive to go cart forward even at idle?
Is the engine on a kart already? Sometimes when it's not installed it will still spin. If installed on a kart then yes if the belt is spinning then the kart will move forward. First thing I would do is turn down the idling rpm.
@@-DIYPRO- yes its on the go kart.. is there something that let's the clutch free spin? Or does the belt slip over the pulleys at idle? I'm guessing the pulley on the engine has to turn when the engine turns.. just confused on how the belt doesn't try to spin all the time making the cart move if the belt is spinning
Sometimes if there is no load on the engine (like the wheels are up off the ground then it can do exactly what is shown in the videos but as soon as you put it on the ground then yes the pull will free spin until the rpms get higher. Yes sometimes the belt will spin as well but it will not have the force to engage the driven pulley. You can test it out by rolling the kart over to tree or something stationary. Try starting there, that will stop it from taking off in the event of it engaging while just at idle.
What is the min and max transmission ratio?
Not sure, they don't say anywhere, my guess is because it's hard to measure since it's pulleys and not gears
I see you are using a 40 sprocket. I tried too, but chain rubs against the aluminium plate (both sides) could you tell me any tip ? Thanks in advance
I can't remember which chain it is weather its 40, 41, 401. One of them is really fat and even though it fits on a 40 sprocket it's too wide. I'd looks up the specs on which one you have and the others to see which is thinner.
Use a 420 or 41 if you don't want the big fat 40 chain. All will work on that sprocket.
@@Deucealive75 thank you
I just added another washer.
Can you use a double roller chain with this?
Now sure how or why but I guess if there is enough room for another sprocket, then sure why not.
How do I find the same torque converter because I want one for my gx390 but I’m scared that the shaft size is to big so it won’t fit
EBAY
you only have to change the
toothed belt along the time ?
I installed one of these on my predator 212cc and when I drive in the dirt it doesn’t drive even though I’m pressing the gas pedal all the way down it just stops. Why is that?
Dirt, says it all right there. These aren't that great when dirty, oily, or wet.
@@-DIYPRO- I figured it out, the belt wasn’t engaging because I didn’t have a part of the torque converter on right. I will keep that in mind though thank you!
What size is the belt I can’t find them anywhere
So is this like a variatior? Like on a scooter?
What series belt is that
Similar to the comet 40 series.

Do i need a torque conveter or can i just have.the clutch driving the wheels
There are a lot of factors that go into that question. You'll see these torque converters on the bigger go karts that are heavier and need the low-end torque to get it going. Have you just have a little kid Kart then your typical centrifugal clutch will do just fine.
@@-DIYPRO- i do just got a kid 2 seater. It came with a anemic 163cc. Im thiking of putting in the predator 212cc directly to the wheels as i am a cheap lad😁
Good video.why do I go through so many belts?
I had a belt driven motor cycle and the swing arm got bent a little not something you could see but eventually it caused my belt to break maybe something is not lined up right or slightly bent
Will not fit on a Colman mini bike unless you cut a lot of the frame.and why would you do that
Good to know.
now how do you connect to kart
What gearing do i need for optimal speed and torque with a torque converter?
That's a good question because gearing is so important. But no one will know how to answer without knowing what tire size you are running. How tall is the tire? Mini bike or go kart?
@@Deucealive75 in a go kart with 200 cc and 6,5 cv, what do you recomend ?
@@felipeluizfelten How tall is the tire? The tire size is important if someone were to make a decent guess where to start on their gearing. To find how tall the tire is you have to look at the tire and find the largest number of the three numbers there. Or measure the diameter with a measuring tape.
@@Deucealive75 the size is 22/10/8
@@felipeluizfelten With a torque converter I would start at no less than 7/1 gearing. Be sure to get more opinions on this from others with go karts.
You could see at the end of the video that the belt alignment is way off.
That may just be the angle of the video. The spacer/ mounting plate keeps the alignment straight.
ممتاز
I have the same torque converter but I have an issue when the belt starts to retract after letting of the throttle the pulley doesn’t seal up all the way and stays slightly open causing the torque converter to not disengage which stall the engine. Do you have any idea what’s causing it.
Look at other videos. Your missing a brass bushing that runs on belt during idle
Do you know what size but is on the driver I can't find out anywhere
Can you help me that how to buy this comet CVT
Search ebay for "go kart torque converter". Double check that the clutch bore size matches what you have on your engine.
What size of motor is that 13hp
I think it is their 11hp
When I start my engine my belt doesn’t move help me pls
Is it just idling? It shouldn't move until you rev the engine.
is this a 30 series
