Noisy Clutch

Hi Everyone,

Happy New Year!! I hope you all had a good holiday

A strange new rubbing sound has started coming from my bike - im pretty certain that its coming from the clutch side. The noise gets quieter as engine speed increases but it still sounds pretty rough. I stripped the clutch down yesterday but cant see anything visibly wrong.

Any ideas?

Bargos.

Well I had a closer look at things and when I removed the centre of the clutch I noticed quite a lot of heavy scoring on the back - it looks like something, perhaps a fragment of clutch plate or gear got lodged down there. Ill put it back together and let you know whether that sorts it.

I'd be interested to hear how you got on with it as I've just stripped a friends clutch to find the source of an odd noise that sounded like mains but wasn't. (cos they've been done). Turned out to be wear in the 2 needle roller bearings and the inside of the clutch centre cog that they run in. Leisure trail wanted the thick end of £250 for a clutch basket!!! So I'm still searching for a solution. Maybe get a machine shop to bush the cog??

Hey Skip,

I wont get around to it until this weekend...ive got to rework the clutch centre as, in my impatience, I broke a couple of the 5 studs that you screw into to hold the pressure plate down - if the clutch costs £250 then it will be worth spending my time on fixing my cockup as I estimate the centre costing the thick end of £100.

I reckon you're right and that you could get a machine shop to engineer a bush that will push into the clutch centre. This will be better than the original Honda solution as it wont wear directly into the clutch body.

£250 sounds like a lot of money to me - if you can get the part number from somewhere I guarantee that another Honda will run the same clutch as the CRM and that you may be able to pick one up from a breakers.

Good Luck!

i had to buy a clutch basket from leasure trail last year and it was about £65, and i thought that was bad! check it out again it can`t be £250.

The kind of thoughts that keep me awake at night...

I dont think that my repair job is going to work - I will have to speak to LT to get a price for a new clutch centre.

Lesson learnt - more haste, less speed and patience is a virtue

Just checked with LT an dthe hub costs around £65 all in.

Hmmmm...that would be somewhat annoying!! Lets be sure we're talking about the same thing. I have wear to the needle roller bearings that the whole clutch spins on, and so consequently wear to both the top hat section sleeve/bush at the back, and this is the expensive bit - wear to the inside of the cog which is permanantly attatched to the clutch basket (which I've now been told by an engineering firm cannot be bushed!!). The part is numbered as 7 I think on the exploded diagram on this site.

Yo Skip,

The hub is the centre of the clutch, ie the part that has the 5 studs that you bolt the pressure plate to.

What reason did they give for being unable to bush the basket?

Did you get a part number for the basket/part that you need to replace?

Hello Bargos,
Engineering co said that to put in a reasonable sized bush would take too much out of centre of cog, so weakening that part. Couldn't do it with any guarantee of whole thing collapsing.
However I've bought a secondhand one from tony in leeds whos advertising the frame for sale - dont know what else is available, whole bik

e pretty much I think.

Hi Skippy.

I see - sounds like you are sorted now anyway.

If you remember I thought that maybe a piece of clutch plate or gear cog had got behind the clutch hub and was making it rub, due to the fact that the back of the hub had some quite bad scoring on it. Anyway my new clutch hub arrived this morning (to replace the one that I damaged) and it, too has some scoring on the back!!! I imagine that this is some kind of engineering finish that they do at the factory, so now I am back to the drawing board as Im starting to think that maybe the balancer shaft is on its way out, oh what joy
