clutch noise

When pulling the clutch lever in on my 84 vf1000 it makes a knocking noise on the clutch cover and can be felt with the hand. At first I just thought it would be a sticky clutch as the bike had not been used for some time, but with the cover off I can see where the clutch has been scuffing on the inside of the cover, can't quite work out what is causing this to happen, any ideas you guys?? Was going to take clutch apart but mr honda has fitted a weird nut that needs a special tool which my dealer wants £30+ for, has anyone found a clever way to get this nut off without the tool or am I going to have to spend some hard earned cash:frown:

 

Bump!

I'm having the same problem right now, please help me bring life to this ancient tread.

 

Just read somewhere on here or VFRD in a recent post about how to make your own tool for disassembling the clutch basket. As I really didn't have a reason to absorb the info I don't remember anything more then they used an old disc or part of, to hold things stationary in order to remove the Nut.
Definiatly shouldn't be rubbing the case cover.

Goodluck!

 

May be due to some normal wear if that close of a tolerance. Pulling the basket off and inspecting the bearings and torque may be in order and check the end play on the primary shaft.

 

I'm not familiar with these setups - my history is mostly dirtbikes with cable clutches, having said that, could it be a clutch slave cylinder issue...??? If the slave piston isn't fully retracting, perhaps it's forcing the pressure plate to engage the clutch cover... If the tolerance is already tight, it may only take an 8th of an inch extra movement to cause issues but not be so much as to stop the clutch engaging enough for normal riding...

Just thinking out loud here, happy to be put back in my box at any time... :smile:

 

Just dug into my clutch. I was able to remove the weird nut with a hammer and punch - was not that bad. Everything looks good except the basket wobbles on the needle bearings. I believe there is just enough play to cause the knocking, and the basket to wobble and rub the inside of the clutch cover. New bearing and sleeve on the way.

I have spent the last 30 minutes looking for something to use as a drift to push the old bearing out.


Frustrated because I could not find anything in my garage, I sat the clutch cage on my bench, and the bearing just slid out!!!!


I cleaned the bearing and the sleeve and placed them together. Just by my fingers alone I can feel a little slop. I can also feel just a slight grinding when I spin it with my fingers.

 

Just replaced the needle bearings and the bearing sleeve. They are a little tighter but there is still slop. I'm beginning to believe a little slop was built into it. I'm exploring a different cause of the ticking of the clutch against the inside of the clutch cover when the lever is pulled. After a close look, and recalling the engine had previously laid down, I believe the cover may be simply dented in. I took a grinder to some high spots inside the cover and gave it another test. This time it's a little better - but not gone. I know the clicking will go away once I remove enough metal.

I can not detect any play in the transmission main shaft ball bearings. Can anyone explain why there are springs on the back of the clutch basket, and why there seems to be two sandwiched gears that are slightly offset behind it. Could a failure here be causing the whine?

I know old engines make more noise however this is not the first 1st gen engine I have ran. The whine is NOT normal.

 

Figured out what was causing the knocking... And no it was not out of sync carbs.

My donor engine took a slide in it's previous life. I did not think too much about the scratches (gouges) on the clutch cover when I first got it, figured it would be cosmetic only. I cleaned up the outside of the cover and painted it to make it look better. I finally paid attention to the cover and noticed it was visibly dented inward. I did not want to attempt to bend it back out for fear of causing a crack. So, I took a grinder and knocked the hell out of the raised reinforcing ribs on the inside of the cover. Put it back together and fired it up - No more knocking!!!!
