GY6 / 150CC CV Belt Removal, Clutch Replacement & Springs

A very good video demonstrating how to remove/replace a Chinese scooter's CV belt, clutch and clutch springs using ORDINARY hand tools. The Clutch on this scooter had a broken pulley, which is why it "appears" to be more difficult to remove the belt. On a fully functional clutch/pulley, this removal would be a fairly easy task. Keep in mind, this video shows how to remove the clutch pulley if you DO NOT have an impact wrench available, otherwise you would use one!

Man, just wanted to say how much I am enjoying your GY6 series. Ive just acquired a super low use, 1000 mile 6 year old 125CC scoot that has been standing in a container most of its life. It revs a whole bunch but wont go over 40 MPH. I suspected a problem someplace in the CVT and by watching your videos, I've gone from never seeing one of these engines to knowing all about them before I even break out the tools. You are a legend sir, thank you from merry England.

[@electronicsNmore]

Those fins are not sharp. If you do it carefully, position the belt properly, and make sure the belt is ALL THE WAY DOWN in the clutch pulley, you will have no problems at all. I have done is many times before with zero damage to the belt. I have the same exact kevlar belt.

Flip flops are excellent for crowd control. They see the jandal they step back.

[@megadawg342]

It ended at disassembling the clutch. What happened to the re-assembly? And what springs(Yellow, Blue, Red) and why those were used. 1500RPM YELLOW Torque Spring combined with Blue 1000RPM clutch springs is what I like. BTW,.. there is no such part called the Variator Spring, it is called the Torque Spring.

[@Kjell-ErikAndersson]

[@electronicsNmore]

No need to. You can do it if you want. LOL What you do not seem to understand is the reason why it seemed difficult to remove, was because the clutch was DAMAGED and would not open fully. Ordinarily it would come off much easier. You have to be crazy to remove the variator fan just to change the belt.

[@iflyquadsfpv9633]

I have new TVS Jupiter and it is just 4.5 months old and just 2550kms total run. 2nd free service is done. Tyre pressure is ok. Engine oil and gear oil is just changed few days ago. Rear tyre is freely move. My problem is that the scooter is always start to vibrating around 45 to 50 km/h speed and if two persons are sitting on scooter then its vibration increases and start from 35 to 50km/h speed. After 52 km/h speed no more vibrations. Vibrations coming from handle, floor board and slightly from rear side when pillion also sit. Is it required to use sandpaper in clutch cover, clutch shoe, rear tyre assembly and rear brake shoes and also clean the clutch cover and greasing the rollers in clutch and variator? I see some videos on internet to use ragemaar/sandpaper in rear tyre's internal assembly area, brake shoes, clutch shoes and also clean the clutch area and greasing all rollers of clutch and variator but it is not mentioned in TVS manual book and also service centre guys had never done it. I told this vibrating problem to TVS service centre during free service but they just tight the all screws. What you think, what is the actual problem of vibration around 40 to 50 km/h speed. Is this a problem of clutch shoe, Variator, rollers or something else? What is the solution? Please help me.

I pit a new clutch on and wheel still turn with the clutch (locked up) any ideas?

[@vproduction]

hey boss, my scooter is accelerating poorly but OK when speed is over 50km/h. I've changed the carburettor and drive belt but now I think the clutch is wearing out as there is a huge clearance between the pads and the drum's inner wall. do u think the pads are not grabbing onto the drum hard enough at lower rpms? can u see if my clutch needs replacing or should I change in some lower rpm springs so it locks in hard earlier ? please see the pics postimg.org/gallery/62lq7j2e/

[@electronicsNmore]

Hi there. VERY nice quality images. Everything looks fine to me. You still have plenty of pad thickness. It would be a good idea to clean the pads and inner lining with brake cleaner before reassembly. I use 1500rpm springs and 15gm rollers. If you also live in a hilly area, That combo may work great for you. If you live in a flat area, then you can use heavier rollers(up to 18gm).If the engine sounds fine as you are accelerating, but you don't accelerate well, then your transmission is the issue. Make sure the clutch pulley opens and closes smoothly by hand(ALL the way and back). Also inspect all the clutch springs. I would replace the large contra spring inside the clutch assembly also with a 1500 rpm. Also inspect your variator assembly for wear(remove it). Thanks For watching! Be sure to share and rate a thumbs up.

[@petriadevilliers5156]

electronicsNmore - Thanks for the great tips! I was wondering (I'm a novice, so please excuse the stupid question) does jour 1500rpm springs give you a higher top speed? I'm busing rebuilding a Johnway 125cc.

[@electronicsNmore]

No. All the 1500 RPM springs do is determine when the clutch begins to engage to turn the rear wheel. If your looking for higher top end speed, replacing a worn belt can give you higher top end speed. As the belt wears, it gets narrower and does not ride as high in the pulley. You can also try using heavier rollers in your variator. You will also have better gas mileage, but you will have slightly less power up hills. Making sure your caburetor mixture screw is properly adjusted, can help also. Thanks For Watching! Be sure to share, and rate a thumbs up.

Hello, I need help with my scooter Keeway Silverblade 125, i bought it two months ago, and i drove on it maybe 300km when something went wrong. When scooter was working properly it could get to 9000RPM, but now around 6000RPM it looses power and something starts squeeling from variator. I tried to replace rollers in variator, i replaced springs in clutch and "big" spring but all it did is that it doenst squeel so much. But the main problem is still there when i hit 6000RPM i can´t accelerate anymore and i have to release gas, and when it drops down a little the scooter is again behaving fine until i hit 6000RPM. I am thankfull for any reply.

[@electronicsNmore]

I'd never run it at that high RPM. Higher RPM = SHORTER engine life. Replace your belt.

[@Majky684]

@@electronicsNmore I forgot to mention I also replaced belt, and nothing changed. And I also forgot to mention that when I hit 6000RPM and don´t let go of gas, it will go down to 5500RPM and won´t go over until I release gas and re engage it.

An impact wrench and cheap Ebay impact bits would have done basically everything here.

I have many people that email me private messages, so it is very hard to help everyone, but it does sound like either your belt is worn(and is slipping), or you need to replace your clutch assembly/springs. You can buy them on Ebay cheap. This info only applies if the engine is running perfectly. If your engine is cutting in/out, then you may have a carb problem or timing issue.

[@gregschille1388]

Why are you rigging up all that stuff to hold clutch in place while your trying to loosen the nut ??? Dude all you have to do is hold the rear brake on and you can loosen the bolt. Impact is ideal to loosen the nut while holding the brake in.

[@electronicsNmore]

If you have an impact wrench, then yes, you can hold the wheel using the rear drum brake. Without an impact wrench, you hold as shown. Even if you have an assistant squeeze the lever, the rear wheel can still move. The rear drum brakes aren't the best.

[@gregschille1388]

@@electronicsNmore"Rear brakes aren't the best" ! Replace the brakes asap. Rear brake lever is on left side, same side as clutch. I was able to hold brake in and hold impact on nut at the same time. I'm sure you could do the same using that pipe in your video to extend your ratchet length. Hey,, just thought you might mention this to your viewers as another option to securing the rear wheel when removing the nut on clutch. If your brake can't hold then definitely replace the brakes on rear before riding next. I'm sure you would agree with that. Take care , wish you well.

[@electronicsNmore]

What?

[@electronicsNmore]

Could possibly have a film of oil on the lining inside of the clutch or pad surfaces. Clean with brake cleaner. You may also have a faulty clutch or the springs require too much centrifugal force to allow them to push outwards against the lining to engage.

[@ormonddude]

Have you ever considered lubricating the shaft with antiseize before installing to prolong life? not much or it could get on the belt and make it slip just a little antiseize on the spring shaft so it continues to function?

I tried taking off my belt like this video and the other CV belt removal by squeezing clutch assembly. I can't get the belt pushed down all the way and I am wondering if it is faulty? I am also noticing the rear tire doesn't spin freely when on the center kick stand and when I try to push the scooter when not running it is very difficult. Another sign the clutch is bad?

[@electronicsNmore]

Aaron Woolhiser When the scooter is on the center kickstand, the rear wheel should spin. If it does not, then the clutch or gears in the rear wheel are bad. Some new inexpensive belts are made slightly wider making them very difficult to install using the method shown in this video. After the belt is pushed all the way to the bottom of the clutch pulley, you may need to take a small piece of 3/4" thick wood and tap the belt further down into the pulley. Doing that will help get the belt around the variator.

[@mr0x013]

better first remove variator then remove belt and then remove clutch

[@tilligetbig]

how tight does the variator bolt go back on?

[@electronicsNmore]

If you do not have an impact wrench to reinstall the nut, then you should gently clean the threads on the crankshaft and inside the nut with a wire brush , wipe the threads clean with rubbing alcohol on a cloth, then apply medium strength thread locking compound(Loctite) to the threads before tightening the nut back down. Doing this will prevent the nut from loosening under high RPM's. You can use an oil filter strap wrench to hold the variator when you tighten it. Make it tight, but do not get carried away.

[@tilligetbig]

electronicsNmore I have an impact wrench but when removing I drew a line on the nut and washer (which both come off when removing) so now for re-install I don't know how tight to put it, so just hit it with a impact gun a little and that's it?

[@electronicsNmore]

Don't worry about it. Hold the variator with one hand tight as you can, and use the impact wrench to tighten it down. Not super critical, but make sure it is tight. If you are paranoid, use the Loctite medium strength blue thread locker.

electronicsNmore Thanks. What weight does your scooter have ex works? And do you have to use heavier rollers with the 1500 rpm springs?

[@nathanielbrown1056]

hey bro I love your vids very good instruction. I have a roketa 150cc and am tricking it out I.E new racing clutch 1500rpm springs, new variator with 14 g rollers, and I am wondering about what you call that part that was faulty in this video? I would like to get a spare just for when I do encounter this problem. Its not the clutch it is those two disks that hold the belt . WTF is that part of the clutch called lol! thanks, and you are awesome for actually replying to people scoot on bro!

[@nathanielbrown1056]

+Nathaniel Brown i see you call it the pulley, but when searching ebay for a 150cc pulley it does not show this part unless you purchase a full assembly.

[@nathanielbrown1056]

+Nathaniel Brown is it called the Performance CVT sheave???

[@kevinroberts8257]

where's the best place to order the clutch assembly for cheaper then your local parts store?

[@electronicsNmore]

Hi Kevin, You can buy a complete gy6 clutch assembly on Ebay for around $35.00. Thanks For watching! Be sure to check out my video playlists, and don't forget to rate a thumbs up.

When I start my scooter it seems it is in gear. I have to start it with it up on the kick stand. It will not idle. Is that the clutch?

[@electronicsNmore]

If you start the scooter, and it is ONLY idling(Normal RPM 1200 or so), and the rear wheel is spinning, you need a new clutch. Thanks For Watching! Don't forget to rate a thumbs up.

What is the advantage to changing the large spring to a 1500 rpm spring, verses the factory spring?

[@electronicsNmore]

Hello Dave. The large spring(Contra Spring) is what adjusts how the clutch pulley opens, which affects the gear ratio between the variator & clutch. The spring determines the level or torque. The 3 smaller springs determine how much force is needed to allow the clutch pads to push outward and engage the clutch bell. I think factory uses a 1000 for the contra spring.

[@haywireinohio]

Mine is all stock and seems to get sluggish in the high end of the throttle I don't know if I need to rejet the carburetor or what

[@electronicsNmore]

Dave Hayslip Check the valve clearances and make sure the timing marks line up. I have a video for that. Could be a carb issue if the valves & timing are OK.

I love the flops!

paul trainer That is all I wear. When you live on a tropical island, that is the usual footwear.

Hello, I've seen your video for diagnosing sounds from the engine, and I believe my clutch has gone bad. I have about 12k miles on my 125cc scooter, and when riding it yesterday it starting banging really hard once around 35 mph. I noticed after inspecting my wheel turns without throttle, and I have been getting a decrease in performance lately. In addition, where is the best place to buy parts from in your opinion?

[@electronicsNmore]

Jake L You need to remove the CV cover and look at everything.

[@ZenWoodworks]

electronicsNmore clutch it sticking and I'm having trouble getting off the belt, and the clutch is also warped. appears to be similar problem. where do you get your parts?

[@electronicsNmore]

[@chisme121]

nice informative video., and nice flip-flops lmao

[@mirakel64]

coud you explaint te me what locktide is?

[@electronicsNmore]

Loctite is a thread locking compound. I used the red high strength type when I re-assembled the variator nut or clutch assembly nut. If you have an impact wrench, then you do not need any loctite. You can hold the variator fan using a strap wrench, then tighten the nut down with a ratchet. The loctite ensures the nut will never loosen at high RPM. 4 years I have used it, accumulating thousands of miles, and never a failure. Thanks For Watching

[@patrickwood347]

Great video! I'm having clutch area noise and bogging down at certain speed. Have you this this type of problem with this CVT? I've already been through carb and ignition troubleshooting. Thanks!

[@electronicsNmore]

Bogging down at higher speeds is usually a valve adjustment issue, bad timing(marks not lined up as shown in my valve adjustment video), or a faulty spark plug/ignition coil/CDI.

[@patrickwood347]

Thanks for the fast reply! It is at low speed. It feels like it wants to "shift" but can't.

[@electronicsNmore]

Patrick Wood Probably a faulty clutch/variator
