Title: squeek when releasing the clutch Post by rijopiatt on 09/09/14 at 13:37:07 2012 S40 with 6,000 miles. On a four bike family ride yesterday, with me in the #1 or #2 position and my son always #4, he kept hearing a squeak coming from my bike. First he thought is was me beeping my horn then later, he seemed to think it was when I would hit a bump- maybe bottoming out. I wear a hearing aide, but when I ride I wear one ear plug instead, so I didn't really hear it. So- today I took the bike thru its paces without an earplug, but no hearing aide either. What his was hearing is a squeaking that I've heard since I got the bike new, but I guess I've just gotten used to and tune it out. It sounds like "nyeeek" and is present when I release the clutch going up or down thru each gear. It is slightly sustained "nyeeeee" after releasing the clutch on the downshifts. I've just thought it was intrinsic to this bike and have never owned another to compare. Comments? |

Title: Re: squeek when releasing the clutch Post by verslagen1 on 09/09/14 at 13:52:55 I'd work thru the usual culprits 1st (speedo, headlight, covers) just to be sure. Then align the belt. But I think the most likely (although extremely rare) throwout bearing. |

Title: Re: squeek when releasing the clutch Post by Dave on 09/09/14 at 13:53:34 "We are the Nights that say Neeee!" Do you get any squeeking if you bounce up and down on the seat? Do you get the noise if you pull the clutch in and out when the engine is turned off, or if the engine is running and the transmission is in neutral? |

Title: Re: squeek when releasing the clutch Post by jcstokes on 09/09/14 at 18:09:59 If you brought the bike new, do you have any factory warranty left? |

Title: Re: squeek when releasing the clutch Post by rijopiatt on 09/10/14 at 10:18:37 Ok- to answer some of your responses. 1. No factory warranty left. 2. No squeaking went bouncing up and down on seat. 3. No noise with engine off and pulling on clutch lever. 4. No noise running and in neutral. 5. No speedometer, headlight or covers loose/rattling. So- I'll find the belt alignment info on the forum and do that check next ( after I finish my new motorcycle jack adaptor plate project) and report back. Thanks everyone. |

Title: Re: squeek when releasing the clutch Post by verslagen1 on 09/10/14 at 12:14:30 The thought on belt alignment is sometimes the belt will run to one side or the other when engaged vs. coasting or engine braking. To keep the belt from squeaking, you have to adjust it to ride in the center. |

Title: Re: squeek when releasing the clutch Post by justin_o_guy2 on 09/10/14 at 12:34:42 Prove it's the belt before you put time into it. You can rub wax or soap on the edges, If that stops or changes it,you might be onto something.might wanna get some on the teeth,too. The front pulley can get a little loose and make noise,but I don't remember anyone who has ever reported a "nyeek" sound,but the cost and pain that problem causes would have me checking it out if I couldn't find what is doing it right away. |

Title: Re: squeek when releasing the clutch Post by raydawg on 09/10/14 at 16:22:30 I bet belt..... I have been down this road myself and have done all the snooping. When playing with different belt remedies, I can get the noise to go awa, or change its tune. My next "fix" will be the Botified Belt to help remove a few members from the band :-* |

Title: Re: squeek when releasing the clutch Post by rijopiatt on 09/14/14 at 20:55:23 OK- I just checked the belt. At the point I started rotating the tire, the belt was in the center of the rear pulley for about half a rotation. Then It drifted to the left just enough to be touching the left shoulder of the pulley for about a quarter of a turn then to the right until it touched that shoulder. That doesn't seem like much movement. Is that worth trying to correct? Also I found that I can hear the squeak when I rotate/back-off on the throttle quickly without squeezing the clutch in all gears. |

Title: Re: squeek when releasing the clutch Post by verslagen1 on 09/14/14 at 22:21:29 If you got a belt that bouncing off both flanges, you got problems with that pulley and that could be your squeak. |

Title: Re: squeek when releasing the clutch Post by justin_o_guy2 on 09/15/14 at 08:21:11 And,before you go spend time on it,you can Prove it Is the belt in a matter of minutes. Or,you can go spend time fighting the belt and hope that is the problem. I'm betting it is the problem,but before I knew,I would not want to get involved in it. Just wax it and see if that kills or changes the noise. How much time have you spent trying to figure it out since I told you the quick,easy way to prove to yourself it is the belt? More than it would have taken to wax it and know for a fact,I guarantee you. |

Title: Re: squeek when releasing the clutch Post by Dave on 09/15/14 at 09:26:28 I wonder if the rear hub damper/bearing are worn out? What else could allow his belt to wobble from one side of the hub to the other as the wheel turns? Grab your rear pulley and try to wobble it.....it should move a little...but not a lot. |
|
Title: Re: squeek when releasing the clutch Post by justin_o_guy2 on 09/15/14 at 10:38:40 Really,Dave? Why not Start with proving that the belt Is the source? I bet it is,but until he KNOWS he can't be sure what he is fighting. Once he can definitively say that the noise is from the belt,then it's time to start looking at why the belt is making noise. Until I hear that the belt has been waxed,you guys can keep solving the problems that are not even isolated yet. |

Trying to wobble the pulley by hand is a 10 second test.....nothing needs to be removed or taken apart, and it might just explain why his belt wobbled from one side of the rear pulley to the other when the tire is rotated. Seemed like a reasonable use of 10 seconds to me. :-/ |

Title: Re: squeek when releasing the clutch Post by Bluesman on 09/16/14 at 08:23:37 I had this thing happen when my belt was a tad too loose. It wandered all over, and made noises both on downshift and engine braking..a loud "whee". Could be it just needs tightening up a wee bit. |

Title: Re: squeek when releasing the clutch Post by thumperclone on 09/16/14 at 09:43:22 im at 4500' when I ride up and over the grand mesa 10,000' I get a squeak then get back down to the valley it goes away temperature swings affects belt tension I use a silicone spray lube |

Title: Re: squeek when releasing the clutch Post by Tocsik on 09/16/14 at 15:28:44 I've been getting front pulley "chatter" or squeaking for a while now, too. Mine happens only with normal acceleration but I don't hear it with generous acceleration; may just be drowned out by the Dyna. I don't hear it on decel. After reading some posts here, I may need to check the front pulley and make sure the nut isn't loose. But, if that's all good, where specifically are you applying the silicone lube, thumperclone? |

Title: Re: squeek when releasing the clutch Post by thumperclone on 09/16/14 at 18:13:29 on the teeth and edges of the belt keep it off the back tire |

Title: Re: squeek when releasing the clutch Post by rijopiatt on 09/17/14 at 14:43:25 Ok- I rubbed beeswax on the belt edges and all their corners. It did not stopped the sound. FWIW, The "whee" sound experienced by one member is closer to my "nyeee" than a squeak would be. I rode about 150 miles today, playing with different scenarios. Again, I hear it when pulling in on the clutch, shifting up or down. I can also hear it if I twist the throttle down quickly (without the clutch) while traveling, say above 40 mph. I also checked for play in the rear pulley, and I can wiggle it. How much movement, if any, is acceptable? |
|
Title: Re: squeek when releasing the clutch Post by justin_o_guy2 on 09/17/14 at 16:53:34 Make sure that front pulley is not moving on the shaft. I'm surprised that the wax didn't change or eliminate the noise.. The rear pulley is rubber,well,mounted,kinda.. There are pie shaped chunks inside there. They Do wiggle. How much is too much? I don't know how to say.. I shimmed mine up tighter with strips of inner tube. |

Title: Re: squeek when releasing the clutch Post by rijopiatt on 09/18/14 at 05:38:03 Today I'm going to check the drive pulley tightness with a torque wrench. Do I need to jack up the bike or simply have it in neutral with the rear brake applied. Also, the Clymer manual says to install a new lock washer-is this necessary? |
|
Title: Re: squeek when releasing the clutch Post by Dave on 09/18/14 at 05:55:35 When you bend the lock washer away form the nut, you can just bend it up in another spot when you lock it down again. I like to double duty this, and I take the nut off and clean up the threads, and use Loc-Tite on the nut was well as using the bent washer. If you decide to tighten up the rear hub....I used rubber floor mat to cut some pieces and a light dab of silicone to hold them in place while I assembled the hub. Dave |

Title: Re: squeek when releasing the clutch(fixation?) Post by rijopiatt on 09/18/14 at 12:03:35 Ok- I just checked the drive pulley with the torque wrench and the nut is torqued to at least 90 ft.lb. from the factory. So, this is not the problem. Since this sound has been there since mile one, is it simply intrinsic to the bike and I've become fixated on it? Are there other things to check or just ride on? |
|
Title: Re: squeek when releasing the clutch Post by justin_o_guy2 on 09/18/14 at 12:46:36 You did fold the washer back up to keep the nut from backing off,right? |
|
Title: Re: squeek when releasing the clutch Post by rijopiatt on 09/18/14 at 14:07:49 Yes I did. |

Title: Re: squeek when releasing the clutch Post by polarpilot on 09/20/14 at 11:41:48 1. Take the bike out on the highway and run it up to 100 KMPH. 2.Pull in the clutch and throttle back. 3. Coast to a stop listening for you squeak. 4. If you hear a squeaky rub a bar of plain old bar soap on both sides of the belt. 5. Squeak or chirp ( mind chirps) should be gone. |

Title: Re: squeek when releasing the clutch Post by thumperclone on 09/20/14 at 12:23:07 there's a fibered stick on isolator(#14789-24B12)between the belt guard and the front pulley cover with bike off and on the side stand gently hit the belt guard with the palm of your hand |
