Please find below the pics of my old Clutch bell.

[ATTACH=CONFIG]167945[/ATTACH][ATTACH=CONFIG]167946[/ATTACH][ATTACH=CONFIG]167947[/ATTACH]

The problem with this bell was.... When I used to release the clutch in Neutral, I can hear a strange sound. After removing the bell we found, there was a PLAY between the bell part and the gear part (2nd img). I dont know how to explain this.. But if you hold this bell and twist it otherside.. I mean Aluminuim on different side and Gear part on different side...They were moving a diffrent bit...Thats what I call it as PLAY....

As you can see in the second image..... back gear is connected to bell with the help of Revet. Between this revet there is a Rubber, which were worned out. He simply replaced those rubbers and fixed the Revet with the help of Lathe work. NOW THERE IS NO PLAY IN IT.

This was done earlier too....but it only lasted for few months....So we decided to change the bell it self....

May be today or Tommorow we will be fitting it back...the same old repaired one....Once I get the spring we'll install the new one....

I'll keep you updated on this....

Coming to your Bike...Id suggest to remove the bell and take it as a sample...it will be easier to buy...Clutch bell for V2 will cost 1600 and V1 1000 rs. Do you have pic of your Clutch bell??

Also, when you go to buy this...Take clutch hub center, both the plates along...Just to make sure you're buying the correct bell...

I did suffer the exact same problem on my fz.
Bike sounds good with clucth lever pulled but when released and on neutral the sounds like a tractor(dhak dhak dhak ).
When clutch was opened for inspection freeplay was found.Did lathe work and there is no free play now but still bike doesnt sound that good and after the lathe work strange noise(kat kat katttt) kind sound is heard on low rpm and on 1st and second gear.Clutch bell of fz was coated 5000 nepalese rupees(3000+)
Indian rupees by the svc so making gugad with the rebeted clutch bell.

Re: Yamaha R15 v1 clutch bell problems

Update on this...

I got the same old repaired Bell fitted for the time being (till I get the spring). I can barely hear the sound that used to come earlier. I know this repaired one will not last for long, as this is second time. I'll follow-up with Gurukul guys to get the spring for the clutch.

Tanmay@ Y don't you try to repair your bell. This stop the further damage that may occur. Once you're able to arrange the funds, change the bell... Just a suggestion.

Also, I can now confirm MINE one 38B1 series.... Again thanks for this information....

I ran it for like, 4-5k after I go it in second had, don't know how long it ran like this before but with me that is super hard cornering thing we are talking plus two slide offs but it is still the same, haven't got any worse, it is pretty recent that i heard about this problem and identified it. Only problem I have because of clutch bell is vibration it causes which increases linearly with rpm, reduces front end feel a lot even on totally stand up up braking. I don't mind noise at all.
So if I have to change it now, it would take 3-4 hours if I move really fast, that too working with the engine oil which I hate. I might have funds in few days, enough to get this. I know each part, the procedure, dis-assembly diagrams and time. It is going to be swift job.

And regarding that play between primary meshed gear and clutch bell.
I think I understand another problem of me here. That rubber seems to be acting as a damper. When I got the bike, I had a weird problem. Say bike is in gear, leaving the clutch engaged whenever there was a crack-opening of throttle, there was a jerk and then the power delivery was pretty linear. Understand it as a chain snapping, it is loose when coasting and then snaps up under power and that is why bike jerks. Go in first-second gear, leave clutch engaged and start coasting, now as you open the throttle it jerks a bit like a power off to on transition and then its all normal, hope you get it. Now I thought first it might be due to the chain tension but it was not, I even changed the sprocket dampers but it didn't help. Now I think that jerk is because play where you found and those rubber bushings in there. It only used to happen in first 2 gears where more torque is available, 3 jerked a bit but 4-5-6 where quite smooth. This play explained all of it.
First time i tried cracking open throttle, the bike was leaned over serious and it nearly made a scene out of me.

Hope this helps anyone having same problem.

I got what you mean to explain. I have a small question for you. Are you going to perform DIY for changing bell? I mean its not as easy as we think. I'm not sure about your experience in this and availability of tools. About me.... I spend most of my week offs (working in BPO, so two week offs

) at my friends Garage. Actually, he was my classmate. I know each and every detail on this, but still when it comes to disassembling something in engine, I prefer professional. Changing plastic parts are easy... Like opening screws and replacing it. But you need to be more careful while replacing engine parts.... Coz a small mistake might reduce the size of your wallet. Especially, when we perform a task in tight budget. Please do post the pic, when you change the bell.

Yeah man I willbe doing DIY. When I bought the bike it was completely thrashed out, I restored it fully now it is almost as good as other v1s and even more appealing in looks due to facelifted rear.
I have been around bikes since I was born, worked on my first bike when I was 16, it was a yamaha rx100. Restored that thing with my dad full time for 15 days or so made it brand new. Now I am 20 and almost in final year of mechanical engineering, we also made a car for SAE team which I will be driving in february.

Though my main passion is motor racing, I keep working for some cash during my vacation at my dad's friend garage. It is not only for cash, its fun for me.
Plus I have all the tools I need. I have changed a bell once, it was of the rx100. No bells change since then, but lots of plate changes after that. Hopefully this skills will help me to prep up the bike when I hit tracks.

will post here when I start the job , maybe even a DIY.

What u mean by Cracking open throttle.is it a joint pipe b/w throttle body and air cleaner box. Mine was also suffering with the same problem. Not giving smooth power delivery.

Then i v change the joint pipe.

Me too having same clutch bell sound problem.
What happen if we rigidly fix the bell aluminium part with gear steel part. This type of setup also exist in old bullet model .

No, cracking open throttle I meant as in switching the throttle on. That initial transition from no throttle to 1%.

Can't say for sure but bullet is made to stand upright, this thing if for corners. Imagine fitting rigid setup and leaning in corner and cracking open throttle and it will jerk. Now that in enough to make rear slide with just enough gas. If you don't lean hard, try it. It is a 'no go' for me.

Re: Yamaha R15 v1 clutch bell problems

Update on Repaired Bell:

The repaired bell is not making any sound, as it used to make it earlier. As I mentioned in my previous post, this bell is not going to last longer. I\'m still waiting for Clutch spring, I\'ll change the whole set and update the post with pic.

Thanks,

Hiten

Re: Yamaha R15 v1 clutch bell problems

Was facing the clutch bell thud thud noise issue .
Ask svc they recommend only change clutch bell solve the issue & disappear noise.it cost around 1.3k.
I performed a DIY at home to change clutch bell rubbers.

This part is making noise as it have little check/ gap between steel gear & aluminum bell.

So disassembled it , open rivet , there are some rubber as seen in pics below

Tried to find same rubber in marketbut not found anywhere , then a mech show super splendor 's clutch rubber which will fit in r15 bell . Fitted the super splendor rubber and the thud thud sound gone completely

Re: Yamaha R15 v1 clutch bell problems

Hi,
I own yamaha fz v2.0, I have run 12,000 kms now
I suffered with this clutch bell problem since few weeks
yesterday I had given bike to 6th free service in Pacer yamaha, Hebbal, Bengaluru
they charged me 700rs for clutch bell resetting (350+350=labor+lathe work charges)

But i dont understand why does this problem arise 1st of all and why do service center guys charge labor when i am running in free services still ?

Can anyone help me....

Re: Yamaha R15 v1 clutch bell problems

For those who are wondering what is that lathe work. Here is a video how new rubbers are replaced. I believe its due to low rubber quality used causing issues, which is aggravated with hard engine braking, high rpms at low gear etc. The geared primary wheel is coupled to the aluminium clutch basket via rubber dampers/bushes. This acts as cushion between engine and gear box. Back plates is to hold the rubber bush in place with Rivets. These rivets does not transfer any power to the gearbox
