Good Job explaining the process for taking it apart and reassembling the pieces showing the pictures without a lot of unneeded boring video and nice recommendation on the moly lube..I went and bought a can and I'm spraying the parts as I type.
Excellent job on this!!! Thanks for taking the time, it was very helpful and allowed me to explain the functionality of the drive and driven clutches to my son.
Thanks so much for making this video. I am currently fixing up a Skidoo Boizzard 5500 with a Rotax 503. My next project is to do this procedure you have outlined. Thanks!
Thanks for the video. My 12yr. old and I just started the build of a Manco Dingo(basket case) that we stumbled across. this is our first cart with a torque converter.
Good video. I noted the 2 bronze guide bushings you spoke of. The new aftermarket one I bought uses steel bushings now instead. These stick and gall the sheave shaft. I replaced with original Comet bronze bushings. Should be much better.
I'm pretty sure you just saved me not only money on buying a new torque converter but from having to sleep on the couch for a week because of buying a new one haha, thank you so much for this video.
Just wanted to say thank you for all the videos and info you have put out there. Great job and ive learned alot from what you have provided so thanks again.
Don't know if you'll be able to answer this but I have a dilemma. I'm converting my 40 Series TC into a jackshaft but I need the drive sprocket mounted on the OPPOSITE (back/inside) side of the main plate on the rear shaft. Im simply using a centrifugal clutch on the crank, chained to the jackshaft, and from there to the rear axle. The final sprocket is fixed in place on said axle. I can not find a video or explanation of what shaft/bearings I need to make this work and whether or not I NEED a pillow block bearing for extra jackshaft support. Love your videos and happy Veteran's Day. {Mounting a Honda gx340 on a chinese quad for a ride to work because its getting cold out}
Thanks! I know that this video will be helpful to those that have a 40 series torque converter. I don't expect a lot of views, but those that need to see it will get the benefit!
glad this is short and informative, cause i'm going to sit my 6yr old grandson down to watch this and make him do the work. with my help of course, cause his attention span isn't long. seems to take to fixing things with great enjoyment. thanks for the tips, oh we're going to work on a Yerf-dog go cart
I just cleaned my comet 40 thanks for the video saved me some money! I get a lot of smoking from my belt which just messes up my drive pulley not sure why. Any thoughts on why that could be happening?
Hmm doesn't sound good. Are you using the correct belt for the center of Jackshaft to center of engine shaft distance? (Google comet 40 series belt chart). Also what is your tire size and gear ratio?
Great video so thank you. Question, im new to these,,,when starting to go and before full rpm it feels like pretty nasty shaking going on,,,bad enough i thought the motor was loose,,,is this common cause of these needing serviced? What i have now doesn't look bad at all but i know guy i got it from had it sitting in pretty nasty garage (moisture,etc). Thanks for any insight
I like your video.it very important to do step by step and explain all the little detail parts. I like how you did it and showed how to put it back together I haven't seen your other videos. But this is my first time breaking all this down so the little Details Matter. I don't want to mess nothing up I want to thank you. I might message you if you have time just to pick your brain if I can for help
Very good video it helped me out to let me know what type i had and will for sure help with rebuilding. The sleeve in the middle is broken so if you know where i can get the part i would appreciate it very much. Thanks Dave
I'm not sure what you mean by sleeve. Maybe the brass bushings? Drive or driven unit? Either way, the only place to get parts for them is mfgsupply.com and if they don't have it you are SOL and need to buy a new unit. Common replacement parts are the wear tabs, springs, and roller weights. Other stuff may not be available.
Great video.glad i sub to this channel,T-MAN referred us to it.Look forward to seeing all these vids on gokarts.Got my own to work on a 2004ish murray.needs work.Thanks for the videos.
Just bought a 40 series set. How do I know which way the driven clutch needs to be mounted (inboard or outboard). I bought a reverse wound spring but not sure if I need it. How do you know which way the driven clutch is supposed to turn to work correctly? Any help is appreciated
mfgsupply sells parts for the 40 series torque converters. Worst case scenario, you can get a whole new unit. Take pics and go to diygokarts.com forum, lots of good info and advice there.
+KartFab sorry for the late reply but thanks a bunch! - i opened it up and one of the springs just came off. re-twisted it and it works fine! only problem is that it comes together when i open my motor's choke. not sure how to fix that though,
my driver had 4 brass rings, 2 under the snap ring that I assume the belt rode on, one above the snap ring and then one at the other end of the spring. Seems to me that the one extra ring above the snap ring would stop the sheave from movin in all the way, so I opted to leave it out. did I figger wrong kartfab? its a 1980 manco 8 hp 3 wheeler
Some versions have no brass rings in the middle. The middle brass rings keep the vehicle from creeping forward when idling. If you mess with the ones that the spring uses for proper tension, you mess with all sorts of things that shouldn’t be messed with.
Just bought a $100 go kart with a blown out spring (It's hanging out). Also no rubber clutches, all are gone & one where the clutch foot has a welded screw. The go cart pulls and gets to speed with me on it. I'm 200lbs. It's an old 2 seater mango fox with a 6 5 Tecumseh. I wouldn't mind keeping it broken if that's what's "throttling it down". I have a Perfect condition 30 series Comet Torque-A-Verter from the same era(homemade 4wheeler my uncle made...long story). But should I save it for when then one goes & they are older?
Man that sounds bad. Post up pictures on www.diygokarts.com and people can help you there. Less back and forth. Honestly it could be something simple, but it’s easier to just take a bunch of pics and get the forum to look at it.
Just out of my own sheer curiosity, could one mount a torque converter driver on a jackshaft instead of the PTO from the engine? One would run a direct drive from the engine to the jackshaft and the TC works from there. Is this possible to do?
they do this for some disc clutches (see here www.buller.net/Category/bully_468su ). Yeah i would assume its possible but why? It would just take up a lot of space and be one more thing that can go wrong + you have to buy an additional jackshaft and bearings in addition to the one you already have to have for the driven unit, so thats two jackshafts, +bearings + sprocket or whatever else that will probably break or stretch from the drive unit to the engine.
debating on either doing a 2 speed jackshaft or having the TC on a jackshaft. I had gotten the idea from fab forums' mini chopper build, where he made a primary off the engine and ran a 2 speed jackshaft. I liked the idea, but would rather use a torque converter instead, while still keeping the primary for aesthetics mostly.
+Robert Cataldo you can look up a table on that, but real world I just impact it on with a drop of blue threadlocker. Doesn't take much and you don't have to worry about it backing out with threadlocker.
Can you clarify the three spring holes? You say middle is stock, one is for speed - is that top speed, or hole shot speed? Also, you said one is for off-road only. I have an off-road kart and I wand hole shot speed - which hole should I use?
As in the alternator? Starter? You are a bit vague but if you mean taking off all the components that generate electricity and just use the engine it’ll work just fine.
The driven unit is "driven" by the drive unit. Basically pulling the belt more and more towards the center of the driven unit. RPMs, roller weights and roller springs and load determines when the drive unit engages. The driven unit spring can be tensioned to resist the drive unit and engage at a higher rpm, or tensioned to engage sooner, so they both work together.
Do you do these on the side? I have one that needs to have cleaned.... If so can you let me know what you charge...I would send you a return shipping label
bartp27772 bart, its not really worth my time to do this, however, check out diygokarts.com and ask in the general discussion if anybody would want to do it. You may get someone to do it for you. Pictures work well too.
Hey I have this kind of torque converter in a of road go kart the guy I got it off of didn't give me all the parts like the Jack shaft can you send me a picture of yours to see how it is supposed to go thank you in advance
***** cool, didn't think I would get a response so I went with immature comment. Now with grow up comment. Is there a certain amount of times to spin or preload the spring when reassembling the driven??
Yes, but it would be extremely difficult to pre-load the spring beyond where it is supposed to load. Just look at the spring end positions on the video at 6:15, and make sure the wear button is resting against the correct slope of the cam
Good Job explaining the process for taking it apart and reassembling the pieces showing the pictures without a lot of unneeded boring video and nice recommendation on the moly lube..I went and bought a can and I'm spraying the parts as I type.
Thank you! Extremely helpful in getting my 40 year old Heald Hauler back up and running!
Thank you for being the only video showing how a reverse wound yellow spring is to be oriented , huge help bless you
It’s a sacrifice I gladly take on.
Best video ive found! No other videos ive watched actually show the correct clocking on the driven! Ty!
Too many noobs out there. I’m old school and too legit to quit.
Excellent job on this!!! Thanks for taking the time, it was very helpful and allowed me to explain the functionality of the drive and driven clutches to my son.
Working on a build,was told reverse wound spring.Your video is perfect,thanks!!
Great video, still helping people years later.
Thanks so much for making this video. I am currently fixing up a Skidoo Boizzard 5500 with a Rotax 503. My next project is to do this procedure you have outlined. Thanks!
I was about to buy a new converter set, but now thanks to your video I know I don't have to... Thanks a lot
Good tutorial - to the point and very practical.
great video, I bought a pulley set and then learned that I needed the yellow spring, so I'll try to change the spring over
Great video! Did this on my 10HP Snowdog and it makes a huge difference.
Thanks for the instructions ...helped me save a few bucks and made my grandson HAPPY
+Greg Sullivan glad to hear it's fixed!!!
Now I see what my clutch is suppose to look like, now I can see why the sheave is pertruding out so much. Great video!!!
What a relief your video will save me no telling how much
Good vid refreshed me on how to do these havent done one since the 70,s
Great video for maintaining Comet clutches.
Thanks for the video. My 12yr. old and I just started the build of a Manco Dingo(basket case) that we stumbled across. this is our first cart with a torque converter.
Dingos are the best! I have owned a few of them. They are heavy duty and made to last!
Good video. I noted the 2 bronze guide bushings you spoke of. The new aftermarket one I bought uses steel bushings now instead. These stick and gall the sheave shaft. I replaced with original Comet bronze bushings. Should be much better.
I'm pretty sure you just saved me not only money on buying a new torque converter but from having to sleep on the couch for a week because of buying a new one haha, thank you so much for this video.
haha i know that feeling, thats why i started a youtube channel so i could spend my youtube money on torque converters!!!
Great how to and no supper loud music good job
Just wanted to say thank you for all the videos and info you have put out there. Great job and ive learned alot from what you have provided so thanks again.
Excellent video. Very professional with thorough explanation. I have my CVT cover off and I’m going to give it a go.
Very helpful! First time trying this on my trail wagon. Thank you

Whatever works. Check out my mini bike big block conversion video
@@KartFab looks great but i dont have a welder...
Great video! Awesome job explaining the process step by step.
So the reverse spring for the driven is if you plan to spin the driven counter clock wise correct?
AWESOME vid! Very informative! Thanks for taking the time to record the procedure. Im sure youll gain ALOTTA views! Keep up the GREAT info!
Thanks! I know that this video will be helpful to those that have a 40 series torque converter. I don't expect a lot of views, but those that need to see it will get the benefit!
Proper cleaning maintenance is way cheaper than replacing a neglected torque Converter . Use GENUINR USA BUILT COMET BRAND PARTS .
I'm doin this right now on a old manco 3 wheeler, just what I needed. thanks
Great video. Thanks for taking the time to help us.
Glad it was helpful!
Exactly what I needed to know, thanks for taking the time to make this video.

Hmm doesn't sound good. Are you using the correct belt for the center of Jackshaft to center of engine shaft distance? (Google comet 40 series belt chart). Also what is your tire size and gear ratio?
thanks friend for your video a question what is the measurement of the belt
Hi great video,which hole is best best climbing hills,thank you
Middle hole is best. If you have issues still, then the hole that gives the most pre-load is the one to use.
Great video so thank you. Question, im new to these,,,when starting to go and before full rpm it feels like pretty nasty shaking going on,,,bad enough i thought the motor was loose,,,is this common cause of these needing serviced? What i have now doesn't look bad at all but i know guy i got it from had it sitting in pretty nasty garage (moisture,etc). Thanks for any insight

Watch the video through the end. Your answer is literally In the video. Towards the end
Any advice on new springs and parts? I have one that I believe some components may be broken. Any advice would help. Thanks!

Do lube the same areas on the 30 series too?
Great tutorial, thank you for putting this together.
What is the difference in the colors of the big springs?
Excellent info, well presented...thanks.
What would u recommend for off roading go karts a regular centrifugal clutch or a torque converter
Centrifugal clutch with jackshaft reduction, or a torque converter would work.
Just bought a $100 go kart with a blown out spring (It's hanging out). Also no rubber clutches, all are gone & one where the clutch foot has a welded screw.
The go cart pulls and gets to speed with me on it. I'm 200lbs. It's an old 2 seater mango fox with a 6 5 Tecumseh. I wouldn't mind keeping it broken if that's what's "throttling it down".

ok good luck with that. Let me know if it pans out. I see no point in doing what you are proposing, but i do the same kind of things just because.
Love it! Thanks! - Going to get started on my kids kart right away....
Great video. Well explained and very appreciated!
I’m trying to find some info on replacing the sprocket on the series 40. Any tips?
awesome video man. what do you torque your 3/4 crank bolt to?
+Robert Cataldo you can look up a table on that, but real world I just impact it on with a drop of blue threadlocker. Doesn't take much and you don't have to worry about it backing out with threadlocker.
Great video and we save money too! Thanks so much!
Thanks for the great info, will try it to keep from jumping on take off.
Well put together video . Thank you for posting this , it helped out big time : )
No prob.
Great video, it really helped me out.
There... I did one thing for you. I hit the thumbs up. Good lesson.
Can you clarify the three spring holes? You say middle is stock, one is for speed - is that top speed, or hole shot speed? Also, you said one is for off-road only. I have an off-road kart and I wand hole shot speed - which hole should I use?
+RamjetAlpha1 the one that provides the least spring tension
can i use a 30 series driven pulley with a 40 series converter ?
+TheOg Boosjukie No. 30 series has a different diameter, less hp rating, and is assymetrical. 40 series is symmetrical and has a wider top width belt.
Awesome video!! Helped out a lot
do you know if a generator engine would run without the electrical parts
As in the alternator? Starter? You are a bit vague but if you mean taking off all the components that generate electricity and just use the engine it’ll work just fine.
Great video, this was extremely helpful, and saved me lots of time, and money! :D
Glad to help!
Excellent! Thanks for teaching us stuff!
Makes me want to take apart my perfectly clean 40 series.
Great video! Thanks!
I’m so glad I keep my stuff inside😂
Awesome video!!
Is the driven clutch engaged by tension or speed?
The driven unit is "driven" by the drive unit. Basically pulling the belt more and more towards the center of the driven unit. RPMs, roller weights and roller springs and load determines when the drive unit engages. The driven unit spring can be tensioned to resist the drive unit and engage at a higher rpm, or tensioned to engage sooner, so they both work together.
Great thank you. Very intuitive.
What parts need to be lubed on the 30 series?
The part in the middle and the part that the weights rub on.
How do I know if I need yellow (reverse wound) spring?
Great video! Thanks for the help!
no problem
Thank you helped me a lot.
what do you use to lube them?
Which torque converter would fit on a 13hp Honda GX390? just wanted to know as I am going to start a project ?
Thanks for this, super helpful!
Do you do these on the side?
I have one that needs to have cleaned....
If so can you let me know what you charge...I would send you a return shipping label

Huge help! Thanks
Hey I have this kind of torque converter in a of road go kart the guy I got it off of didn't give me all the parts like the Jack shaft can you send me a picture of yours to see how it is supposed to go thank you in advance
Go to the diygokarts.com forum and post up this question there many people could send you s pic and you could post pics up there.
Okay thanks
on the driven unit I have one of the rubber stops missed should it still work
It may cause damage. Just order a new wear tab.
Thanks do you know a good website
Very cool thanks for the info
keep in mind, there are three holes, just put it in the middle..... hehehe. 10 year old me laughs
heh heh i see what you did there.
***** cool, didn't think I would get a response so I went with immature comment. Now with grow up comment. Is there a certain amount of times to spin or preload the spring when reassembling the driven??
