Nasty Clutch Noise:- With extra added fail, now abit of win!

I have a noise on the TDM, it only happens when I pull the clutch in sounds like a ticking.

I seem to remember when taking the clutch apart last (about 2 years back) That the way it worked was a rod with a disc end pushes against a bearing and somehow separates the plates. I'm guessing this bearing has gone anyone have any other ideas?

Video is uploading.

Also any idea what that bearing is called clutch thrust bearing rings a bell.

Also how long would it take to do or any ideas on the cost (TUG/Ben)? I CBA to do it myself. Laughing

I beleive its called a thrust or release bearing.
The one on my car makes a horrific racket, then stops when the clutch is pushed in. I think its a sign its getting old.

It could also be a notched clutch basket.

Where the tangs on the friction plates engage into the "fingers" of the basket, they can start to nibble their way into the metal. This can result in a clattering sound which goes away when you pull in the clutch.

If they aren't too bad, you can remove the basket and file/dremmel them back square. If there is a lot of notching, doing this would leave the whole thing too loose.

Not worked on a TDM but a thrust bearing on the pressure plate should be pretty simple to replace. Just a case of draining the oil, taking the side cover off, undoing the circle of bolts with springs under them that holds the clutch together and the pressure plate ought to lift right off. I'm not sure how the release mechanism is arranged on your bike though.

The bearing would normally just pull out by hand (or drop out if you turn the plate upside down and give it a sharp tap). If the bearing seat has worn, it's trickier. Either degrease and fit using bearing fit compound, replace the pressure plate or live with it.

Could also be the bearing in the clutch basket. If you have to take the basket off for either bearing replacement or to re-dress notches, it can be a pain to undo the centre nut because the whole lot is mounted on a rotating shaft. You either need special tools to hold it still or an impact wrench.

Bearings on the way usually make a rumble sound, so i would go with Stinkwheel on this and say it could well be either the tangs on the friction plates or the clutch basket.

Thumbs Up

Is it worth leaving it till it gets worse or sort it before it properly goes tits up?

It doesn't affect the bike other than the sound.

I would investigate sooner rather than later.
Its an easy job - drop the oil, remove clutch cover, then remove clutch.

part 3 is the thrust bearing which is the most likely cause, if the basket has notches you may feel some clutch slip or it failing to disengage. Could also be the cush drive (springs on the back of the basket). if the bearing looks fine, and there are no notches on the basket, then you need a new basket.

Dont even normaly need to drop the oil to take the clutch cover off on most bikes.

Doesnt the TDM use a seperate oil tank/ dry sump?

hmmm.. i doubt its the springs on the back are gone as it should be ticking all the time. How many miles has the bike done? how many since a clutch plate swap? If the bike feels fine, no slip or clutch drag then its almost definitely the thrust bearing. The thrust bearing has a lot of force going through it so I would advice changing sooner than later (if it disintegrates you can fuck up a lot of components). Does the clutch lever need adjusting quite frequently?

Being brutal with the down shifts etc. will most likely fuck your gearbox before the clutch, however it is not impossible for it to notch the basket.

Changing the bearing will be an hours labour + oil + bearing (few £) they will advise you to change the plates and springs while your there which will cost an extra £100 purely because they can check the condition of the basket and with all those components changed the clutch will last 10,000 miles where as if you keep the old plates and springs they may need doing 600 miles down the road which = unhappy customer.

Definite answer is to take it apart and you'll see whats wrong with it, if you refuse to take it apart, its more than likely the thrust bearing.

I doubt the bolts that hold the clutch springs could come undone on account of the tension from the clutch spring.

When you pull the lever in and the two sets of clutch plates seperate, you are creating a rattle-sized gap inbetween them.

Could just be that. Maybe combined with a slightly worn basket.

Pop the clutch off and have a quick look Cool

No need to drain oil, just tilt the bike over a bit and it won't go anywhere.

Going to tonight, Can't seem to find gasket for it so am hoping the old one will hold.

IT feels perfect now, I do half expect to see my clutch basket fuckered though when I open it

Poorly poorly basket. Shame, as the basket fingers look pretty good.
Weird you can't find the broken bits of plate and basket. Surprised

Simple enough fix tho Thumbs Up

By the looks of the picture, that hasn't only just happened. The broken edge of the basket is all smooth and rounded.

I reckon there's a rair to middling chance the bits have long since been chewed into oblivion by the gearbox.

I think I'd still be dropping the sump to have a look though.

At a minimum you'll need to drain the oil and do a filter change. I predict a haze of minced clutch plate mixed through the oil with a sparkly sheen of aluminium power floating on top.
