- Here is how to mount the aftermarket 40 series torque converter
Sorry this took me so long to install. This was my first time and I did not practice first!🤪
Here is the unit I installed

OMB 40 series units come with the reverse spring

I think you may be the only one on youtube to install torque converter properly. 👍
This kit is perfect. The steel plate alone weights over 9 lbs. Very heavy duty. The bearing sticks out like that to put it closer to the sprocket. The RED spring on the Driven pulley is already the correct reverse spring and works very well. Comet just paints there spring yellow. Good job Eric.
Amazing. That thing looks humongous but very awesome!! I never would have guessed it can go on backwards either! Thanks for the lesson Eric!
Thanks for the info. Putting a torque converter on a go kart for the first time you helped me out. Thank you sir
You’re the man! I’m installing one on a motor I got for a go kart. Just the information I needed. Thank you!!
Thanks master! Saludos desde Mexico 🇲🇽
Good video! Thanks.
Great educational video
Hi Eric, I'm I'm interested in purchasing one of these 40 series kits, I was wondering in your professional opinion, do you think that the aluminum plate will hold up if mounted correctly as yoube shown? Will be for a 420cc 15hp. Thanks man, awesome work.
just what i needed my secondary is just skipping on top of the pads and not engaging i am currently waiting on the reverse spring but the last tracking i have for it is passed through the usps jamaca NY international sort center
Do you have a video of this running? I’m curious as to how long the belts last as one side is generally slanted in more than the other.
Can you mount a sprocket on the backside of the the mounting plate behind the engine? Or does it have to be between the mounting plate and the driven pully?
Can you use this on a 212 predator? I currently have a 30 series and break belts often…
Question maybe you can answer. Yerf dog go kart worked before breaking swing arm. Replaced it with identical swing arm and also identical sprockets and chain. Put it back together and belt slips...won't propel the cart. Driver and driven unit are used but were working before.
I would need to see it. Send pics to help@ombwarehouse.com and I will take a look
Hello, I have a question. I've read that the 30 series tq is good up to 8hp or there about and a 40 series tq is good for up to 16hp or so. My question is would there be any performance gains by using a 40 series tq on a built 212cc predator engine putting out 15hp? I realize you would need to put a sleeve on the 3/4" shaft to bring it up to 1" for the larger front pulley to be used.
The 40 series units are very heavy and the snowmobile guys have been known to break cranks. There is a 40 series driver available for 3/4" cranks www.ombwarehouse.com/comet-44c-magnum-drive-clutch-3-4-.html but I do not recommend using it unless you add an outboard bearing and support for the weight.
I have seen 30 series converters used on 16 HP engines. There are some modifications that must be done, but they will support the power.
The 1" drivers use a 1/4" wide key and the 3/4" cranks and drivers use a 3/16" key. That makes it very hard to adapt!
Great video. It is indicate for what power?
A40 series can handle up to 25 HP when geared properly
I got a 40 series china made. 420 predator turning ccw looking at shaft,Do I need the ccw green spring on my driven? Thanks
Where can I buy a stage 4 clutch and torq converter for a trail master 200 hurricane
My driven pulley bolt is too long for the amount of thread I have. Did you use a different length bolt?
No, I did not, but we have to work around Chinese tolerances. Get a shorter bolt at the hardware store and you will be fine!
hi, I also fitted the same kit, when I walk 2 km I touch the belt and it overheats why?? yours is the same i.e. does it overheat??? or is it normal?
On the driver/driven alignment the driven moving sheeve should be matching the drivers fixed sheeve at full engagement. This will cause a bit of misalignment when not active. Does that seem right or am I losing my sh!t?
I don't know if you are losing your stuff, but I can tell you that does not matter with these units. The symmetric belt is forgiving. Also consider that the original Comet units used the driver mounted conventionally and the driven had the hub inboard...same thing as what you see here, just in reverse! Trust in the Goat...you will be fine!
You forgot to show the versatility of adding a band brake unit! Thanks for the good quality video, keep them coming Senior~

Hi Eric, what can I do to stop my primary from grabbing the belt @ idle tried a new belt same issue idle is set as low as I can go duramax 440, I put into a b200r coleman thanks I'm puzzled
We can change the springs in the driver to the red springs to get the driver to engage at 2000 rpms

Hey, I have a question that I cannot seem to find an answer for anywhere. I want to install a 30 series on my go-kart, but the problem is that the sprocket needs to be on the outside instead of the inside. Is it possible to place a spacer where the sprocket would have been on the inside and mount the sprocket outside?
Nope! That will put too much pressure on the plate and it will break!
@@TheGrayGoatGarage If i weld a piece of metal to the cross bar and add a bearing that goes on the shaft would that help hold it up and prevent it from breaking?
Can you use a belt with the set up instead of chain?
I am not sure what you mean by that. The torque converters use a belt between the two clutches and then a chain to the axle sprocket. I am not aware of a pulley for a belt that will go in the torque converter
Can you put the 40 series driver and driven pulleys on a 30 series mounting plate
Of course not, the mounting plate is half the size on a 30 series.
I installed the same kit just the way you did and did not put a reverse wound spring and my golf cart only does 10 miles in hour and rpm go really high. Is this because I need the reverse wound spring? Please let me know and thank you
Yes. Without the correct driven spring as soon as the driver clutch engages the belt the driven gets yanked open.
You might also consider a larger sprocket. I had the tiny sprocket that was included and got 6-7mph on my golf cart. Upgraded to a much larger one and am getting over 30mph now.
@@TimothysTractors yeah i was stumped for a while but then i put a bigger sprocket on a few months ago and it goes about 32
What about when u use a jack shaft that is with the motor mount.
That is awesome!
@@TheGrayGoatGarage I can’t seem to get them lined up centered.
You should saftey wire those bolts
That is a great idea, I have just never had any issues with those bolts loosening
Can I have the cover dimensions please? Basically plate to outside of cover. Thanks. Good vid.
I am sorry but I don't have that measurement and do not have the parts here to get them measured for you. I work offsite from the warehouse. My apologies
@@TheGrayGoatGarageNo worries. Cheers.
Hi I know this is a very late comment but how did this hold up thinking about getting one but dunno if it’s good enough to put down money for it
We sell a lot of these with very few issues. As long as it is installed properly it will easily hold 25 HP and last a long time. The other option is to spend $400+ for genuine Vomet parts!
Comet!
Thank you!
I bought the same one and my driven pulley goes the opposite way how do I fix it
If you are you referring to the reverse spring in the driven, we have that here

Can you attach a go kart transmission with reverse gear?
Anything is possible! Just not easily
Most reverse boxes would use a driven unit in the input shaft
@TheGrayGoatGarage the one I'm looking at has been tested for the 30 series torque converter but not the 40 series.
Can you put this on a 12 hp Kohler lawn mower motor
If the engine has a 1” diameter crank, yes, you can
You are showing a steel and aluminum back plate. The unit comes with an aluminum back plate. You are not using the aluminum one that comes with it, why? Where did you get the steel one that you are using? Did I miss something you said or meant?
It does not matter what plate it comes with. The installation is the same. I feel the aluminum plate is stronger and I prefer it over the steel plate

@@TheGrayGoatGaragethank you for getting back to me so quickly. Your input will help.
Is this going on a mini bike?
Haha. Nope! I don’t care for big block engines on Minibikes. I would rather have a rowdy small block!
@@TheGrayGoatGarage I figured as much, I just assume you are always working on mini bikes.
How do you know if you need a reverse spring ?
You have to look at the buttons on the driven unit and make sure that when the driver grabs the belt the driven unit is not yanked open
Send me some pics to help@ombwarehouse.com and I can verify for you
@@TheGrayGoatGarage ok will do tomorrow after I receive the new driver and driven pulleys. I will send you what I ordered. Thx
@@TheGrayGoatGarage email sent
Ok
mine keeps burning the belt any suggestions? 😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢😢
Yep! Change your gearing! Need to know more about what the setup is. Email me some pics to help@ OMBwarehouse.com
Engine is too powerful lol.
A 420 chain on such a big engine is a bad idea. The 420 chain is for a maximum of 125cc engines.
How do you figure? 😂
I think you meant to say CVT (transmission), not torque converter. Torque converter is type of fluid coupling unit, which acts a lot like a clutch would. While CVT changes the ratio between input and output shaft rotation speed.
PS. Keep up the good work
These units are commonly referred to as torque converters and have been for the last 50+ years. If we called it a CVT nobody in the go kart or MiniBike world would know what we were talking about!
@@TheGrayGoatGarage And they are still mechanical torque converters. There are some really big ones on DAF cars from the fifties, they ran two one driving each rear wheel.
That belt looks too tight and your clutch is on backwards
The driver unit can work in either direction. It does not matter which way it is mounted on the crank.
The belt is the correct length for that application
10 tooth 40/41/420 sprocket not 12
Hi Aaron
I have not been able to find a 10 tooth 420 chain sprocket with a 3/4” bore
Your description is wrong you said it's a 12 but it's a 10 tooth Check out the description on OMb OK bub
I think you should post a how-to video in great detail to perfection, then once you have done so, then you can be a critic on minuscule topics of someone else's video. Ok bub!
