Transmission with more slap than my ex!

[Fetishkat]

Guys, advice please.

 I seem to have some slack in my transmission, gear change is fine, clutch feels fine, but when I let the clutch out I get judder and it feels like free play has been taken up. 

Is this a problem with the clutch basket?

 

Cheers

Could be cush drive 

[Fetishkat]

Hi Fazz, yeah I wondered the same because of the feel but all seems good back there.

[Dezza]

Has something worked loose?

[Fazz711]

Could be loose sprocket nut? Or loose clutch hub nut?

Does it chatter on tickover from the clutch?

[Fetishkat]

Hi JR, no there’s no chatter 

I think I’m going to have to delve in to the clutch and have a look see.

Springs in the backing plate might be rooted. does it rattle badly at idle?

[Fetishkat]

Had a root about in there last night, there was about 1mm of play with the main clutch nut even though the lock washer was still doing it’s thing. Doesn’t seem to be anything else amiss apart from a few marks probably caused by the movement. 

Would that have been caused by the clutch plates wearing? They are still within tolerance and the steels look perfect. 

Thanks for your help chaps

any ridges worn on the fingers of the basket? assuming that your cush drive is tip top, your sprocket nut is tight and you chain adjusted correctly, and just ruling out other odd issues like checking that all your engine mounting bolts and nuts ate tight, then youre back at the basket, nut needs to be tight and then lockd in placee, if it moves and is only held in place by the locking tab, then get a new locking washer, take it all out, check the lugs that engage the oil pump, the rivets that hold the basket,  the springs and bobbins on the back of the basket (gsx achilles heel) an if they are ok, tighten the nut to the correct  torque before locking it with the tab washer, there should be no movement at all on the nut.

Yes the clutch but needed to be tight, very tight 

If I remember most of the time you will need, or it helps to have the clutch holding tool to get the right torque or the nut may come undone.

if the nut winds off enough the helical primary drive will provide sideways loading and unloading as you open and shut the throttle, each time helping to unscrew the nut a little more. the danger is that if the basket moves enough theres the risk that the gear driving the oil pump will disengage from its slot and you lose drive to the oil pump. youd know about that pretty soon though........
