How to tell if your centrifugal clutch has gone bad
Vložit
- čas přidán 19. 07. 2017
- My 1969 taco minibike has over 46,000 hours on it and it has the original clutch. The clutch started going bad around a week ago when I noticed it was losing power and other signs I included in this video. Enjoy and remember to subscribe and like. "Comment's will be replied"
Dude I'm dying rn lmfaooooo, "okay I'm on the 69 taco" dude I was damn near crying lmaoooo
I know bro 😂😂. I was like 14 when I made dis and didn’t know anything about that at the time 😂😂🤪
Another really important sign. Take a goood long look at your springs. What causes failure 99.9% of the time in these clutches is the springs due to overheating. If you hold the sprocket end of the clutch and spin it back and forth with your other hand and you hear a screeching sound its your springs. When the springs fail the clutch will engage at a wayy lower RPM and it will bog or fully kill the engine at high speeds. This video is extremely helpful, one of, if not only video going in depth on different scenarios to help identify when its time to switch it out, so thanks! Worth noting- clutches are perfect for ON ROAD riding. They can suffice off roading and hill climbing if you have a jackshaft and have it geared low. The best thing you can do (if you plan to ride on road and off road) is get a torque converter! Perfect for low end torque and with a 10% overdrive will give you more top speed. The greatest thing about a torque converter is once youve got it all installed, and something breaks (90% of tbe time its the belt wearing out) you go on amazon and bam you got a new belt for 6 or so dollars.
On the other hand cen clutches are cbeaper than everything - 20-30 dollars on amazon and it also includes a 40 series or 35 series chain. If youre tight on money by ALL means just get a clutch, they work great for 1-2 years and will work 2-4 hears if you lube up the bronze bearing every month.
Thanks for the video and hopefully the info ive shared will help ppl!
This is the only vid out there that explain centrifugal failure. Nice vid
Excellent and informative post!
Also when you are riding downhill and close the throttle, there may or may not be the (bearing) noise from the centrifugal clutch, but different noises from the CC will be reduced.
Mix a 50-50 mix of lucas high temp grease with atf and that will allow your clutch to work for 2 years longer... hope this tip helps someone. 👍
On the bronze bushing or in the drum where shoes make contact? Where to apply this 50-50 mix?
@@scottbrodie3071 this only works on actual cars 😂 idk what this dude was talking about.
All you need is a dab of high temperature grease on the bronze bushing. Do not oil or grease anything else in the clutch!
That is such a cool bike. This video has helped me diagnose the problem with my Go Cart.
Gage Hill Hey man thanks! Shes a oldie had a 49th birthday on april 11. Glad i can help
This helped me so much bro thx this is exactly what i needed
This video helped me tremendously!!! We're 4 for 4 on the signs!!
So helpful been I knew my clutch was gone
marco alejo glad I could help!
I took my engine off my go kart and it runs perfectly fine at full throttle, but when I put it back onto my go kart it just sputters when I give it any throttle and then kills. I think it’s the clutch or chain but they’re both brand new.
Coaxer could be that or something else but maybe try and adjust the carb idle/mixture screw too.
If I understand you correctly, it isnt an issue with the clutch, it is a problem with your gearing. The engine runs fine when it's off the kart because theres no load for it to pull. When you put it on the kart and you give it some gas, the clutch engages, then has to pull both the weight of the kart and the weight of your body. If you put a larger sprocket on your axle, the clutch will have an easier time getting you going from a dead stop. A larger rear sprocket = more torque which it sounds like you need
Actually that works better then most of those clutches I have seen. Most of the ones I have seen jusy get stuck and won't disengage.
Marc Serina they die in many ways I guess. That must suck when your driving and it locks up on you like that
I have one on a motorized bike sometimes you don't have neutral that's all, i have gotten good at taking them apart cleaning, sanding , oiling them I'm putting them back together.
Fantastic demo, thank you.
wvoider09 No problem glad I can help!
Wow man thanks for the video I have every sign u mentions that my clutch is bad I will definitely will be ordering g a new one!!!
Thanks bro i appreciate the info but may i add something... when you ran the engine without the clutch & chain...of course its gunna not bog out on you theres no weight no tension no real work for it but usually when it does that ill clean up my sparkplug and it really helps but it happens rarely for me just check your sparkplug that may be your engines symptom🤙🤙🤙
Ita fixed now clutch bushing was bad. But yea your right the engine was not under a load
I said the heck with all the disassembly cleaning and oiling and reassembling and carrying lubrications in my fanny pack for my minibiking adventures and explorations I embark upon, I came up with a whole new way of getting my power to the earth below my rubber tires. It’s not a torque converter either! Those are just as much work if not more than a clutch because they have more moving parts and a belt then u still have to have a chain and sprocket off that! No thanks. Plus I heard they’re made for girls bikes mainl hehehahahahe😝. I installed a kickstand under my bike that when it’s down my back tire is actually off of the earth maybe 25-30 mm, ( that’s even w me sitting firmly on my luxurious seat made from my moms old night gowns made from red silk, chaahching🏦💃🏼 idk what she wears now that I snagged it out of her top drawer but who cares haheha. Then I went to my neighbor billy who fixes tailpipes for ppl all day and night in his side yard and had him just attach the sprocket to the engine with this special type of welding he knows how to do that actually comes out of toothpaste tubes so now I just start it up while I sit on it and then thrust my tummy forward like I’m on a bucking bronco and the kickstand goes up my tire meets the earth and hang on tight cuz it pops a big wheelie right in front of my arch nemesis neighbor Jeremy across the street from my house and his super smoking hot sister Jessicahhh aah aahh Lynn and I’m off to the mooon ! Or at least to the park down the street where Jessicaahhh aah aahhh meets me to clean my spark plug off for me before my exploration takes way. Best mod I’ve ever made!#clutchesandtcssuckjermeysball
Just read this and I’m dying 😂😂😂 good story 😂
Shot the fuck out
Shot the fuck out
Quick question if you tight your chain and all and it still keeps falling is it because of the clutch?
hi I’m xian not really a clutch issue. Majority of the time it’s because the chain is old and needs to be replaced. I had this issue and I replaced the chain and good to go after that. Or could be you put the engine on crooked
MustangLover 1970 thanks man
Thanks much needed
Brandon Levy no problem at all man if you need any more info dont hesitate to ask👍
So if start my go kart and it takes off running without hitting the gas,i have a bad clutch? I put it on a jack stand and turned it on and it just keeps running.At this point im lost.
That’s normal usually.. but if it’s going too fast try lowering the idle by turning the screw
@@streetstallion thx a lot man.l ll give that a shot 👍
yes you need a new clutch that happend to me few days ago I turned my go kart on and it took off and I found out I needed a new Clutch
Why does my clutch loosen up while driving
Mines make a grinding noise as well as the three you named
I thought my engine was knocking but that’s the same clunking noise it made,
Gunna take clutch off and start it to see if it goes away
Hi mate, is it typical for a centrifugal clutch to work really well until it heats up, because I start to hear the motor bogging out around 1.5 - 2 minutes from a cold start? Everything is well until then.
Usu Caption Hey there, no it was actually hot I was on a ride before the making of this. Had a new clutch put on almost 2 years ago. Does great now 👍
Thanks for your reply. I've got a small plate compactor which as you know works off a centrifugal clutch too. I think you have answered my question as after working well for 1.5 - 2 mins, it starts bogging the motor down and the plate stops vibrating properly. Cheers !!
Does this go for torque converters as well
Just bought a newer doodlebug about to replace the clutch today. It has a real bad shake until I get up to full speed then it’s fine. And the clutch stays engaged and wants to take off while just sitting. Hopefully this will fix it
Tim C I think it might be good to.. just keep oiling the bushing every 30mins-1 hour of driving and you should be good to go
@@streetstallion worked like a charm. Awesome
Tim C glad it worked out!
My cent clutch appears to be making a clanking noise even when just pedaling my Schwinn Meridian. Motor also bogs out sometimes and even stops completely. The clutch also appears to be pretty rusted despite it only being put on back in January. Maybe the guy who put the motor on for me found some other already-worn clutch cause he said he couldn't put on the one I gave him... Hmm..
Mine keeps over heating it brand new and turn hot red
Shii… no wonder my clutch be ringing like that bell all the time, like a dang lunch bell. XD
I bought an old go kart and swapped a brand new predator 212 onto it. The clutch that came with the old engine fits just fine but only engages at a higher rpm. After im done riding the clutch flings out a black oil or grease and sometimes starts to smoke and get very hot. I hope this isnt an issue because I believe that my clutch hasnt been used in a very long time. Does it just need some breaking in?
Nick 04 try breaking it in for a few days and see if any results change. Let me know if anything else happens
@@streetstallion sure thing
Dude its overload protection its ment to do that it may be old yes but its dying because your putting too much stress on the clutch
Ttv Thraxy that’s true on newer clutches. This clutch was from 1969 and the bushing was gone aswell as the drum being so worn out. This vid is 2 years old and I put a new clutch on it 2 years ago and service the new one regularly, no more problems after the replacement
Would my clutch be bad if it literally bent my dead axle wheel bolts? The bolts that attach to the wheel and to the sprocket that connects to the chain
So mine engages a little bit late and then when you go full throttle you can feel it engaging and disengaging
my colmen ct200u does not bog at full speed but when taking off its a little rough and shaky but i have not checked the clutch much
Thanks for uploading. I have a medium grade clutch on my mini bike. Fairy new, I’ve been having an issue with it overheating when I have the plastic cover on. Is there anyway to help keep it cool? I don’t really wanna run the risk of getting my leg caught in it either.
It shouldn’t be overheating unless you put oil inside the clutch drum which causes it to slip. Although it is normal for Clutches to get hot because the whole bike works because of that it’s under a lot of load especially up a hill. 👍
MustangLover 1970 yes that’s exactly what I did. I put chain lube on the jack shaft chain and it got in it. I just tried running it and it shot sparks so I’m gonna clean it and see what happens tomorrow.
Spencer Tree that is a really odd symptom
MustangLover 1970 it should be ok. I think it just got too hot. I opened it up and everything looks okay.
Spencer Tree oh ok 👍 good to know it all turned out well for you
Just confirmed my suspicions. Pickup up an old mini bike tonight that has all your symptoms.
Did u get a new clutch or restored the old one?
@@streetstallion yes. Mine was the kind of clutch that has the pucks held together with "c" shaped brass clips. Greased all surfaces except the ones that make contact when engaged. Works perfect now.
rlachermeier ok awesome! My clutch was just screwed because the drum and the bushing was shot so I didnt wanna waste time with the original clutch. I bought a new clutch 2 years ago and oil it after every ride. No problems now and works good.
I bypasses the governor on the bike I just got used for a few days. I took the zip tie off, and put gas and some cleaner in it and it started bogging on me and seems like it's not going as fast. I was worried I blew the engine or something, but I'm thinking it's the clutch. Especially now that I'm almost done with the video and saw the noise your clutch was making.
is there any high performance clutches if so where do i get them?
SQEeZEE DUCKY Hi thanks for watching and tuning in! You can find those clutches at gokartsupply.com or gopowersports.com 👍
Stop and add oil 30w right by the lock ring and sprocket. It is a brass bearing need oil every 30 minutes of riding ,a gravity feed drip oil will solve future problems if ur forgetful
David Kaul it’s been replaced over 2 years ago and the new one works perfectly and I always oil it. The old owner didn’t seems to look out for the clutch bearing that much because there was no bushing left in the clutch because it was so worn out
@@streetstallion when u by the motorized bicycle kit oil on clutch bearing is not ever mentioned. Rrrrrrrr is what my bearing did ,I actually rebuilt it after Google on why my bike made rrrrrrrrr sound lol thankfully u tube taught me
David Kaul yea this bike is from 1969 so I never got it new... but yea that’s sound kinda is a big jump scare for sure 😂
Thanks man I thought my engine was pinging
Mine chatters, haven't noticed the bog, but haven't gotten to test it out.. my main thing is it chatters and jerks at a real rapid rate....
Very informative, thanks!
Good job
What does bogging out mean? And my bike i get to like 15 mph and it start jerking and wont go any faster is it my clutch? My sparkplug might be dirty too and i need a oil change but still why cant i go faster that 15 even tho mine goes 35 mph easy
i have a similar problem i have a predator 212 and the clutch goes on its own and screams as soon as it’s turned on is their a simple fix
30$ new clutch Amazon
Can that make a grinding sounds and feel when you first take off
Juan Tellez that’s actually somewhat normal. But make sure the bushing in the center get oil
my go kart is doing this but it just wont go up a hill worth a damn, it has a 126 cc subaru robin motor
Jerry Phillips if its governed I would recommend bypassing the govner thats what i did to my briggs and stratton and now has a lot of power for its age. But thanks for viewing
sint 125cc a bit to big for a centrifual clutch?
Thanks a lot of good information from your video 👍
mine might be going out since the engine boggs out when i try to take off
Why when I turn on my 212cc predator motor it turns on and it turns off making a noice someone help
Hey bro,my minibike is pretty new.. for some reason it wont go no more,it starts but wont move do you know what it may be
What does it mean when it overheats ???
Where's the tach on that hog?
Funny you ask because i just ordered one yesterday😂 should be here next week. The original tach was screwed up because it was just so old
I just got a new clutch yesterday and have only ridden it yesterday and today. I oiled the shoes of the clutch these past 2 times i rode, and the bell i can see has a very shallow groove where the shoes are (less than a millimeter deep). Is that fine? I learned that i am supposed to just oil the bushing and not the shoes area, and when my clutch had no oil towards the end of today's riding, it was very strong and grabby like it originally was. Do you think that shallow groove is of any concern? or is that normal for a clutch to have a shallow groove like that? if not, is that a big problem?
nascarsimracing1 yes that’s fine it’s just the clutch breaking in. Just keep up the maintenance. I can already tell you good at doing that. 👍
@@streetstallion thank you!!!
nascarsimracing1 no problem! 👍
@@streetstallion an update with my clutch, i took it apart and realized, that "groove" was actually just oil buildup from me oiling the shoes, which is the wrong way to oil. I cleaned it up and took off as much oil as i could with a shop rag, and then put multi purpose automotive putty grease on the bushing where the bell and clutch assembly meet. None on the shoes. Now the clutch is strong like it should be, and also is completely silent and smooth!
nascarsimracing1 🤣🤣 glad you found out the culprit. That’s the easiest fix I ever heard 😁👍👍
Yeah bro its because I have a Murray track 2 with a predator 212 on it well originally my back tire comes with a huge a sprocket that covers most of my tire so I have a fast takeoff but no top speed okay I didn't have a problem with the clutch when I had the big sprocket it was smooth no ugly noise as soon as I put on a smaller size sprocket so I can go faster it starts making similar noises on the takeoff and before I'm waiting for throttle it has the ugly Shake 2 it as well I feel like it's the clutch but it's weird because when I put the big sprocket back on it doesn't do it I wonder wht this problem is I'm hoping it's just that I need a new clutch because I really don't want to put the big sprocket back on I want to keep it medium size so I can have takeoff and faster speed I just need to find some better forks with suspension by any chance do you have any advice about this problem
When I squeeze the throttle, my clutch will spark.
Emilio Mendoza WTF
Das not normal😂😂
Same did you find a fix?
This is normal inside your clutch are friction pads when the engine increases ram those friction pads push out and grab the outer part of the clutch this friction creates sparks
@@ricoricua3153 I dought it is. Mine is doing this and when I throttle it makes a terrible screeching and grinding sound louder then the engine itself
Nice helped me figured it out
Cool video
So do u get a new clutch
So my clutch has been bad this whole time
Mine is engaging when idle what does that mean?
Luke Butterfield Hey sorry for the late response I had to go to the ER last night.... When it does that usually something is stuck in the clutch drum causing it to make it go. One other this is that your idle might be to high there is usually a screw to adjust the idle 👍👍
MustangLover 1970 no problem I appreciate you answering quickly! Hope you're ok and thank you for the response and helpful video
Luke Butterfield my pleasure!
U could of stretched or even broke spring that holds shoes in place.lower idle or ur glaze ur clutch.
Good information yo know.
The fact that you can rev it higher without the clutch on it doesn’t really say much, the engine doesn’t have a load on it, therefore it will behave differently
Joe you might be correct. But when i punched the gas it was going down steep hill. When the bike was younger i can rev the motor full throttle down the hill but now it was struggling because the clutch bushing was worn. I replaced the clutch and doesnt do this anymore, the old clutch was from 1969 just like the bike and the engine.
Joe it was also a test to see if the carb was going out to. But yea good thought! I would have never thought about it
MustangLover 1970
Oh don't get me wrong, I wasn't saying the clutch wasn't the problem, I've just seen a lot of guys say that an engine is healthy based on what it sounds like without a load. Thanks a ton man, I definitely learned a thing or two about centrifugal clutches from this vid.
How did you run it without plug connected in the video plug has no wire connected to it
Put it on the clutch
My clutch is sparking a little. Should I oil it. Or is it bolted on to tight?
Emilio Mendoza try oiling it first use a thicker oil like a few drops of gear oil or Lucas oil stabilizer and tell me what happened after and I’ll try to help u troubleshoot it from there👍
My clutch is brand new and I put it on with too much p,ay and it has all of those problems but is it bad if it makes a grinding noise
Pretty much thats not a good noise. try putting motor oil in the bushing that sometimes works
@@streetstallion ok
Any suggestions on a type of clutch to get , mine is also doing the same
Ricardo Garcia to avoid headaches get a torque converter or if you engine cannot use one just get a $50.00 clutch the expensive ones last longer, just oil the clutch before and after using the engine
Yeah and that clutch is in the position to fly apart and funk you up!
Its been replaced an the new one is waaay better than the 50 year old crap
my clutch i noticed i can push it inward and outward is that normal?
Eh… I wouldn’t say so. I mean unless you have a solution so it won’t fall off. My crankshaft isn’t threaded so I honestly put a little jb weld on it to hold it on for the time being 😂 I haven’t rode this bike in like 4 years lol
@@streetstallion its got like a bolt holding it in
@@somthingarageMD yeah your chilling 👍maybe try adding a few washers
I just like how the clutch is backwards
Its not backwards what are u talking about
@@Rivooo yo its walmart boy what you doing on a vid like this you got karts and bikes 2?
the clutch should face the other way for several reasons
where does the 46,000 hours figure come from?
I meant around 4600 🤦🏻♂️🤦🏻♂️ was a idiot kid back then lol
mine makes a hum noise that makes the clutch stop then shut the motor off unless ur reving it up
PurpL nerpL have you ever tried oiling the clutch bushing? That need to be oiled every 1 hour of use
MustangLover 1970 what kind of oil cause i dont think wd40 would be good but idk
PurpL nerpL any oil for engines would be ok but lucas oil stabilizer last a lot longer thats what i use i usually put a few drop of lucas in my clutch
MustangLover 1970 haha holy shit worked i used 10w30 oil worked just fine had to let it sit for an hour or so though
PurpL nerpL happy to help glad it went well!
I dont think your clutch is supposed to come off that quick idk just bought a bike 🤣
My clutch will lock up and then won’t spin the tire and the starter
Oil the bushing. I have a video on my channel
My go kart wont go up hills unless im going full speed. Bad clutch?
David Devine that’s actually kinda normal because it’s under a load. Usually 4hp and lower are prone to doing this. Sometimes to the engine just needs a tune up
@@streetstallion The engine wasn't struggling though, its a 5hp. The clutch would struggle when I accelerate though.
David Devine in that situation yes I believe it’s the clutch
Why does my go cart smoke
It could be a lot of reasons maybe o-rings are bad and oil is coming up through them
Is it normal for my oil to smell like gas
No change your oil immediately your carb is ether running rich and your rings are shot or the float in the carb is bad letting gas in the cylinder
If it smells like if it is just gas and not oil that’s bad but it’s normal for it to smell like gas think about it gas and oil does come into a little bit of contact throughout riding
@@sebashtiangarcia6097 your oil should never smell like gas that means its diluted with gas and no longer protects your engine if it smells like it changes it immediately and find the cause or you'll have engine failure I work on small engines for a living I know what I'm talking about...
