Title: Squealing noise when clutch is engaged? Post by kawazacky on 07/05/17 at 17:05:24 Hi guys, Here's my first tech question. Father-in-law's '97 Savage squeals a lot when clutch is engaged, at least at low speed. Seems like it's coming from the belt, but I can't say for sure. At the same speeds, no noise at all when clutch is disengaged (lever pulled in). Previous owner thought it was the tire last summer, changed to a new tire "that wouldn't rub on the belt," and the noise stayed the same. Ideas? Would a belt dressing help? The noise comes in dry weather, not just wet weather. |

Title: Re: Squealing noise when clutch is engaged? Post by batman on 07/05/17 at 17:22:15 Check for loose drive pulley ,it should be torqued to 94 ftlbs .check belt alignment, check for proper tension(don't use the guage that came in the tool pouch the belt will be to tight) you should be able to grab the middle bottom of the belt and twist it 90 degrees using just your thumb and one finger . If your lining up the belt on the rear pulley don't go by the marks on the swingarm ,spin the rear wheel forward and backward by hand ,until the belt tracks in the middle of the pulley.check the rear pulley when you have the bike jacked up ,grab it at 3 and 9 o'clock and wiggle it, if you have a lot of play the bearing may be bad. |

Title: Re: Squealing noise when clutch is engaged? Post by Eegore on 07/05/17 at 18:22:43 Ive had this exact issue, anyone that doesn't own or work regularly on one of these bikes always says its a bad bearing. They are usually wrong. Heres my recommendations: 1: Remove all the belt covers and pulley cover, expose everything. 2: Rub some canning wax on the belt and see if the noise reduces or stops- its probably the belt rubbing the pulley if it does. Wipe off the wax, don't keep a belt lubed. 3: Check the pulley alignment on both front/back no matter what. Do it while having someone on the bike. I found having the belt closer to the interior of the rear pulley is better on my bikes. 4: Check belt tension, use the video in the tech section. A loose belt will yield more long term use than a tight one and its gotta be really really loose to skip teeth. Mess with the bearing last, it takes some work but the belt checks are really easy to do. The tire isn't rubbing the belt but too large of a tire can rub the swingarm. |

Title: Re: Squealing noise when clutch is engaged? Post by kawazacky on 07/05/17 at 18:37:22 The belt-on-tire idea sure sounded bogus to me, seeing that there was no evidence of wear on either the tire or the belt. 5474767E6374110 wrote:

Title: Re: Squealing noise when clutch is engaged? Post by Eegore on 07/05/17 at 19:01:56 Yeah I cant imagine a tire somehow passes through the metal swingarm and touches the belt somehow. A tire expands with speed so if its really close to the swingarm it will rub on the interior right side. If you aren't sure just put some tape inside the swingarm, cruise up to top speed and see if there's any tape stripped. |

Title: Re: Squealing noise when clutch is engaged? Post by stewmills on 07/06/17 at 06:36:29 +1 on the belt tension. I had squeal a couple of times over the years and both times it was a belt that was too tight. On one occasion it only took about a turn on each of the rear adjusters and that was enough to kill the squeal. Remember though, you need the axle nut loosened and the rear tire up in the air for the loosening of the rear adjusters to take effect, then re tighten everything. |

Title: Re: Squealing noise when clutch is engaged? Post by kawazacky on 07/06/17 at 18:31:23 Well I had 30 seconds to look at the bike tonight -- twisted the belt and it seemed like it was loose enough. Will inspect further over weekend. |

Title: Re: Squealing noise when clutch is engaged? Post by justin_o_guy2 on 07/06/17 at 19:18:28 Gulf canning wax from the canning section at the grocery store. Rub a little along both edges of the bottom of the belt. Since you're troubleshooting what you need to see is Change. So, to be sure, move the bike and do it until it is all dressed some. It's okay to wax places you wouldn't wax if you were just trying to quieten the belt and you knew it was the belt. The 05 wouldn't quit squawking, so I waxed. |

Title: Re: Squealing noise when clutch is engaged? Post by piedmontbuckeye on 07/08/17 at 07:57:21 Disagree on aligning the belt and ignoring the marks on the swingarm. Those marks are there for aligning the wheels/tires TO EACH OTHER. Not aligning per marks properly will result in improper, even dangerous tracking! Belt tension is most important as others have correctly mentioned above. Most people make it too tight. Also great advice above is checking the pulleys to make sure that they are tight to their respective mountings. Rather than using wax or belt dressing, use a silicon spray. I use a can of food grade silicon spray - probably purchased from McMaster-Carr. Use it lots in a plastics factory that make plastic food containers. It will not harm anything, and it will quickly tell you that it is probably not bearings but dried rubber to pulley noise - that's what mine was. An application lasts me approx. 500 miles or so. |

Title: Re: Squealing noise when clutch is engaged? Post by justin_o_guy2 on 07/08/17 at 08:21:05 I don't disagree. But I know where to get wax. Not sure about the spray. I even explained Where to get the wax. The swingarm marks may not be aligned. Use them,if they are. |

The swingarm marks, again, are for wheel alignment, and not to be used for belt alignment. I would think that Suzuki would have had better quality control and make these marks reliable for what they were intended for - has much to do with handling safety. The brand of spray can of silicon I use was "Sprayon" and a quick Internet search it (along with other brands such as LPS) is sold at Grainger and even listed as a Wal-Mart product. Using the NON-food grade version is even cheaper. Around $6.00 per can and very easy to apply. Spin the wheel and spray the belt as it goes by! |

Title: Re: Squealing noise when clutch is engaged? Post by piedmontbuckeye on 07/08/17 at 17:04:51 If you align the marks as Suzuki expects and then you have misalignment problems of the belt/pulleys, then you have other problems, maybe loose pulleys, or bushings wore or something else. |

Title: Re: Squealing noise when clutch is engaged? Post by Dave on 07/09/17 at 03:57:33 Check you swingarm marks and confirm that they are aligned. Measure from the chrome caps for the swingarm pivot bolt to the axle on both sides......and see if they measure the same. |

Title: Re: Squealing noise when clutch is engaged? Post by batman on 07/09/17 at 20:37:48 The marks on the swingarm aren't right because your either spreading thr swingarm to put the wheel in or compressing it when you tighten the axle ,either way the ends are flexing which will change the length between them and the swingarm pivot point.If the bearing on the axle are good (2 wheel-1 pulley) and the spacer s are not damaged ,when you align the belt you also align the wheel( and tire if the rim has no runout). |

Title: Re: Squealing noise when clutch is engaged? Post by justin_o_guy2 on 07/10/17 at 00:54:47 The flex changes both sides. And it's not to the width of a hair accurate. No problem. |

Title: Re: Squealing noise when clutch is engaged? Post by batman on 07/10/17 at 11:49:27 JOG the flex may change both sides ,but if you look at the forward brace ,in front of the tire you'll see that the tire doesn't run in the center of the swingarm and the brace is asymmetrical where it's welded to the arms, it's longer on the side where the belt runs ,making the flex uneven. |

Are you saying because the axle compresses (or spacers and hub expands) the distance between the forks that the length of the forks change?... a measurable amount? I don't think you can measure the distance in Angstroms. |

Title: Re: Squealing noise when clutch is engaged? Post by batman on 07/11/17 at 00:00:18 True,but do you trust the marks to be accurate in the first place,We know there are differences in the size of main frames and I doubt we'll find swingarms are welded the same either.Are the marks stamped before or after assembly?I 'm not about to listen to belt noise or risk damage to the belt ,to get a few more miles out of a tire that may or may not be misaligned . |

I can't imagine any compression or expansion of the swingarm side to side could be that significant on the length of each arm. Trig it out, and roughly it is a 2 to 1 (from my memory) would mean that compression of the arms (let's say .010) would only yield a length difference of only a few thousandths. Hardly significant. Besides aligning the rear wheel has more importance that just tire wear. It also affects handling which is far more important. In my mind, also, is the fact that this is a crucial issue so I still would trust Suzuki on the marks rather than just a lightly squealing belt. Virtually impossible to measure oneself unless set up on a stand with a laser measuring device. |

Title: Re: Squealing noise when clutch is engaged? Post by Eegore on 07/12/17 at 17:26:06 "Virtually impossible to measure oneself unless set up on a stand with a laser measuring device." Interesting you say that. I did this on a 95 to check pulleys, tires, bearings. So are you saying to use the swingarm marks to align a tire by making sure the marks are the same, or to just use the marks as a guide? On my bike the swingarm marks are not aligned, but according to more modern technology the wheel/rim is. |

Title: Re: Squealing noise when clutch is engaged? Post by piedmontbuckeye on 07/12/17 at 17:55:21 I am just saying that all of this alignment assumes that the frame and its locating points for the swingarm to attach to are in proper location AND that the swingarm was mfg. so that it is also uniform (i.e. not twisted or bowed or somehow mis-aligned from pivot points out to marks) AND that the marks are properly stamped in (probably after assy was welded and stress relieved). It would be hard for any of us to measure any of this using any techniques that we as users might have. I think it would take a CMM (Coordinate Measuring Machine) that would be large enough to accommodate the whole frame.) Also important would be the steering stem in relation to the rear swingarm. Its angle and precise position. I once as a employee at a Honda dealer changed a tire for someone on a smaller bike and I didn't properly align the rear wheel to the marks and the customer knew it right off by its handling. I corrected to marks and it worked fine then. I am just saying that the rear adjustment and marks are there for rear wheel alignment to the frame, not to be ignored to get belt aligned or to keep from belt from squeaking. |
