Driven Clutch rubbing on Idler Chains ??

[tshea]

Purchased a 2000 conquest recently and am on a slow learning curve - lots of experience with amphibious airplanes but none with vehicles. Though lots of grease appears to be a common thread - anyway - as the title says - at certain speeds and rpm's the driven clutch rubs on the idler chains - makes a ting ting ting noise. Would changing the spring in the driven clutch fix it ?? From what I have researched on this site it appears that the driven clutches may only be good for about 400 hours and mine has 500. Shimming the driven clutch is an option but sounds like a band aid solution to me

Any thoughts or ideas would be appreciated.

Thanks
Todd.

Sounds like your driven needs a new bronze bushing in it.

As drew wrote bronze bushing probably wore, also check that all the plastic slides are in place and or the snap ring on the end has not let loose.
There should be 2 shims between the clutch and the step on the input shaft.

Thanks guys - I am assuming its just a standard oilite bushing ??

That's what I would do. Just measure it up and use an Oilite or Symmco plain sleeve bearing.

Congrats on the conquest, they are an awsome machine. If you find nothing wrong with the clutch try pulling the brake caliper on that side and remove that primary chain. Check to see if there is any up or down, in or out movement of the rotor, there should be none at all. We will discuss possibilities based on what you find. Good luck! RR

I just replaced the clutch on my 04 Bigfoot (500 hours)...the bronze bushing was very worn causing excessive belt wear and belt flapping noise. Take a look at to see if there is any wobble in your secondary clutch while reving in neutral....if it does then likely the bushing is toast.

I couldn't get my bushing out of the clutch (my clutch (127-129) was the version that has a retaining ring holding the bushing in) so I ended up buying a new clutch from Argo.

Now this new clutch contacts the brake pad assembly occasionally and I ordered the spacer washer from argo but after a week of riding it no longer seems to be an issue.

With the new clutch the machine is running great....feels like a brand new machine!

Took the driven off - only one bushing - added a second one and all is well now.
Thanks guys for the help - stand by for more questions
