Clutch application noise revisited

[dan filipi]

I had that wrong.
The plates come out assembled and can be removed with engine in frame.

Dan, over on NGW one of the members recommended draining the oil out of an engine and replacing it with diesel. Let it sit for a few days, then run it for a few minutes and let it sit again. Run it again to heat it up and drain it. I did this to my bike and you would not believe the nastiness that came out. It looked like the worst old oil you can imagine. It may help remove some nastiness from the clutch. Definitely easier than pulling the clutch and it only costs a gallon or so of diesel.

Hmm, straight diesel no oil?

I'm thinking on something to try....drain the oil and pour it all in through the stator cap hole.
If it is in fact dry plates, this should immerse the clutch in oil and with lever tied back the plates can't help but get soaked good.

After 1000 miles the plates are all soaked. I'd use atf long before I'd consider diesel. Probably best to pull the plates. Matbe PO got them out of sequence or something.

Pour the oil in slowly. There is only a small opening in the rear cover between the alternator and clutch area.

I've never been keen on flushing an engine with anything so I'm going to try this first.
It's not like I need the bike right away so I can give it plenty of time to soak.

I'm wid Slab on this. At first, it sounded like splines jumping on a shaft, then it got a little quieter. I think it is clutch chatter, too. After riding as much as you have now, there is no soaking to be done that hasn't already been done, imo. A little ATF in the oil might show a small change...if it does, then I think you're only option is to pull the clutches and see what the heck is goin on in there. Perhaps the steels have dug into the basket, and that's whats chattering. Whatever it is, I bet it don't get any better just from riding it. May not get any worse, either, but.... :headscratch:

ON auto transmissions, you can sometimes hear that exact same noise on take-off, and it is ALWAYS at least one clutch disc with stripped splines on it. Bike clutches are somewhat similar in that they are multi-plate, wet clutches. Only takes one that is messed up to make a noise.... :Awe:

 

[joedrum]

hmmm thats sounds very right to me

 

[dan filipi]

Maybe I'll end up pulling the clutch in the end but for now I'm taking the lazy approach.

I couldn't pour oil in through the stator cap so pulled the starter and went that way.
At this level about 1/2 the clutch is immersed.
It took almost a quart before spilling out.
I put in the old atf/gas mix I had from the carb soak experiment.

Clutch lever is tied back.
I'll rotate 180 each day for a week or so then spin the starter to pump this out to the crankcase and drain.

 

[joedrum]

seems like good approach and let lazy work

 

[Steve83]

I would rotate it in gear with the rear wheel locked, and maybe less than 180 degrees, in case less than 1/2 the clutch is actually immersed.

In gear tire stopped, clutch pulled, and rotate engine?

 

[slabghost]

Sounds right. That way clutch is disengaged and turning into the cleaner mix.

 

[Steve83]

The engine turns the basket and friction disks, the wheel will turn the steel plates when in gear. Turn the engine maybe 1/4 to 1/3 turn every day, then give the wheel a turn or 2 in 5th gear. Just wanna be sure all surfaces get soaked.

 

[dan filipi]

Gotchya :thank_you:

 

[dan filipi]

It's been sitting for 3 days clutch pulled in and I've been refilling it through the starter hole each day then turning motor a bit less than 180.
Giving the wheel a spin also.

This weekend I'll drain this solution out and fill with fresh oil.
Maybe I'll get lucky and the noise is gone.

 

[slabghost]

Fingers crossed here!

 

[Steve83]

Yup. here, too! :beg:

 

[Andyb]

Anxiously waiting the results, here, Dan.

 

[dan filipi]

All put back with fresh oil and filter, no change to the clutch noise : (
Oh well, at least a little bonus is with fresh oil and filter the warm oil pressure it at spec so the bottom end is in good condition.
