Title: Rear Axle - right side Post by Jaygee on 09/01/17 at 19:18:43 I have a squealing drive belt, so I checked the rear axle alignment against the alignment marks and found the two sides were not quite the same. I loosened the right side rear axle nut and adjusted the alignment, but when I went to re-tighten the nut it won't tighten! It turns, but is not going tight. What gives? |

Title: Re: Rear Axle - right side Post by Gary_in_NJ on 09/01/17 at 19:35:05 Place a screw driver in the hole in the axle and then drive the nut |

Title: Re: Rear Axle - right side Post by verslagen1 on 09/01/17 at 19:45:22 check the other side of the axle... does it turn too? |

Title: Re: Rear Axle - right side Post by batman on 09/01/17 at 20:12:42 It could be that someone over tightened the nut and striped the threads,take the it apart and look at at it,it should only be torqued to 65 ft/lbs. |

Title: Re: Rear Axle - right side Post by justin_o_guy2 on 09/01/17 at 21:43:31 Yes, the other side is turning. Two wrenches required or an impact And pulse the trigger. |

Title: Re: Rear Axle - right side Post by Jaygee on 09/02/17 at 07:04:05 Ok, feeling like a real dummy! :-/ I was tightening the 17mm bolt and didn't notice that the 24mm nut on the other side was turning with it! Wrench on both sides - problem solved. |

Title: Re: Rear Axle - right side Post by Eegore on 09/02/17 at 08:20:37 Just an FYI those marks are good for individual adjustment but they don't have to match. |

Suzuki put those marks there for a reason. They are there to align the rear wheel with the frame/front wheel. So...unless you assume Suzuki really screwed up, the axle is only properly adjusted when the marks DO match up on both sides! I worked at a Honda dealer for some years, and never once did we run into a bike where the marks were put on incorrectly by the mfg. |

After aligning the rear wheel correctly by the marks, and making sure the belt has proper slack (1/4 turn on bottom of it) I have found that the best thing to do to get rid of the squealing is to use your wife's spray cooking oil (brand name is PAM). It works great and after thousands of miles, I can detect no problems or issues. |

Title: Re: Rear Axle - right side Post by Eegore on 09/03/17 at 10:06:28 I have three 1995 versions of this bike. The tolerance is close but there are variables, with 3 bikes only one has an almost exact match on both sides and we use a shop with laser setup to align the rear pulley and belt now. I believe that bike is .3294mm forward on the left. We had to custom contrast paint the pulleys for the machine to make accurate readings. Maybe all other bikes out there are set up to have an exact match on each side but I can guarantee two of mine don't. I have another swingarm coming in, I can have them all put on to one frame and see what measurements we get. |

I have never seen a manual (either owner's or service) but I don't think any of them say to use the swingarm marks to align the pulleys! I would bet that they say that the marks are there to align the wheel to the frame, not the pulleys to the belt or to each other. Also, .3294mm is equivalent to .0129" or slightly under 13 thousandths of an inch- almost imperceptible to the eye except in certain situations. The swingarm marks are made for visible eyeball setting, not micrometer measurements. Again aligning the belt is different than aligning the wheel. |

Title: Re: Rear Axle - right side Post by Steddy58 on 09/03/17 at 15:58:05 I got the marks lined up identical and when I took it to the mechanics for its annual test he said everything's OK but the wheels are out of alignment and he told me not to put too much faith in the marks |

Title: Re: Rear Axle - right side Post by Eegore on 09/03/17 at 19:55:21 Right .3924 is the bike that has lined up swingarm marks. The others do not but reflect an aligned front/rear pulley. Just an observation I have had with my bikes, but I have yet to place different swingarms on the same frame. |

Title: Re: Rear Axle - right side Post by gizzo on 09/03/17 at 20:55:47 I've worked on more than one bike with misaligned chain adjusting marks, too. Looking at you, Royal pain in the ass Enfield, Daelim, Suzuki and others. My Ducati doesn't even have any marks and I'm good with that. |

Title: Re: Rear Axle - right side Post by Armen on 09/04/17 at 07:09:50 FWIW: Many belt drive rear pulleys have one cast shoulder, and one pressed or screwed on shoulder. The cast one is always on the outside of the pulley. If a wheel/belt was set up to load the inner ring of the pulley, it would be pushing against a lightly pressed on piece of sheet metal. Not good. The way I do belt adjustment: Jack under the bike. Rear wheel free to spin. Get the slack pretty close. Play with the adjusters so that the belt is fairly centered. Turn the adjusters so that as the wheel is rotated, the belt slowly migrates to the outer (cast in) shoulder. Not so much that it is scraping against the edge. Double check the belt slack. Torque the axle nut. Recheck the slack. PS: It's is usually easier to keep the adjustment if you have the axle nut on the right side of the bike, not the left. (ask me why ;) ) |

That also allows you to perform another often overlooked task. Centering the brake shoes. Have someone apply the rear brake while the wheel is spinning. That will allow the shoes to center themselves in the drum. Then tighten the axle while the brake is still applied. On some bikes it makes little difference, while others will have a marked improvement in brake feel. |

Title: Re: Rear Axle - right side Post by Armen on 09/04/17 at 13:10:48 Hmm, Fast, Never thought about that. Not sure how if the drum rotates on the axle, that it would make any difference. Have to try it. Actually, nut on the right is for another reason. Most people tightening the rear axle nut will be using a wrench or torque wrench that is fairly long, so they'll be turning it above the nut so as not to hit the ground. If the axle nut is on the left, and the wrench is at 12 o'clock, as the nut is tightened, the axle can migrate toward the back of the bike as you tighten. This will change the belt or chain tension. I've watched people redo the chain slack a half dozen times wondering why it changes every time they tighten the axle nut. 99% of the time flopping the axle so that the nut is on the right side makes the problem go away. Tightening the axle nut works the axle against the adjuster, which holds it in place. |

Title: Re: Rear Axle - right side Post by Fast 650 on 09/04/17 at 23:28:15 It made enough difference on a Honda that I used to have, that if you even loosened the axle nut and tightened it again with no other changes, I could feel the difference in braking. My other bikes, I could barely tell any difference.I think it depends on how stable the shoes remain as the cam spreads the shoes. If they have a bit of wobble as they spread, centering them allows the shoes to align to the drum for the most contact surface. |

Title: Re: Rear Axle - right side Post by Armen on 09/05/17 at 02:44:37 Thanks Fast. I'll try it. |

Title: Re: Rear Axle - right side Post by Jaygee on 09/05/17 at 09:41:35 My axle is now set to the same marks on both sides and belt is now running perfectly centred. Squeal is gone! Thank you - this forum is fantastic! |

@Armen, I have been battling this issue today. You've just confirmed my suspicion. Tomorrow I will flip the axle and put the nut on the right side. I have aligned the wheel 4 or 5 times previously with no problem, until today. I might not get sleep tonight because I am so excited to have potentially solved the mystery! What a pita this was today! Before anyone asks, I have done the double wide spacer mod and am running the Kawasaki pulley. I think I may have read every axle alignment post on the forum today and tried each alignment "technique" twice. Hopefully this post helps the next person. |

Title: Re: Rear Axle - right side Post by srinath on 07/14/20 at 06:25:10 On some bikes like my GS500 I prefer to run the axle nut to the right - so if you crash it hard, it is protected by the exhaust. Cos if you install it the way it was from the factory and was on the left, and you partially damage it in a crash, you will ahve a real tough time taking it off. But the savage has the shock on the left protecting it and exhaust and shock on the right. Cool. Srinath. |

Title: Re: Rear Axle - right side Post by Armen on 07/14/20 at 06:26:13 JDV, Let us know how it works out! |

Title: Re: Rear Axle - right side Post by ohiomoto on 07/14/20 at 14:39:33 I put something like a wrench or rag in the belt and rotate the wheel until it binds before I tighten the axle. Works for me. |

Title: Re: Rear Axle - right side Post by Jdvt600 on 07/14/20 at 16:59:54 Okay well I just finished. Long story short, after flipping the axle bolt to the right side the belt still makes a loud whine or whir and pulls to the left while riding. After riding, I put it back on the lift and rotated the wheel forward and reverse, without touching the adjusters or the axle nut. Bam! The belt tracks back into the center. Now, I didn't use the scientific method yesterday, it's possible and likely that the belt would have tracked to the center if I rotated it. I'm pretty sure though that I did, and it was sticking to the left. I'm of the same mind as @Serowbot, if axle is square who cares about the belt. Let it live. But the whirring sound was pretty loud and more noticeable then I've heard before. I noticed it whirring yesterday while trying to tune the carb... I also wasn't wearing a helmet. [ch128064] It's possible the lack of helmet, combined with the high temp of 107 yesterday (potentially causing the belt to move outside even more than normal temps) is what drew my attention. It's also possible that a few weeks ago I flipped the belt (didn't mark it). But the teeth look evenly worn and I'm not sure flipping the belt would cause it to whir like it is. Yesterday, after aligning and torquing, the belt would still pull to the outside, on a lift, off the lift, on the road, riding in a box, with a fox, with a mouse, in a house. here or there, anywhere. So, for now, I'm chalking it up to high heat and inadvertent movement during torque. At least the belt tracks to the center on a lift and measures evenly to pivot point of the swing arm. ¯\_([ch12484])_/¯ |

Title: Re: Rear Axle - right side Post by Armen on 07/14/20 at 19:02:23 Maybe put a straightedge along the outer edge of the rear pulley and see how it lines up to the front one? |

Title: Re: Rear Axle - right side Post by justin_o_guy2 on 07/14/20 at 19:37:08 A light piece of strong twine. Under the belt on front pulley, roll to front. Work it back to rear pulley Adjust it in and out so it just exactly rests touching both sides of the front pulley and see how it lines up on the rear |

Title: Re: Rear Axle - right side Post by verslagen1 on 07/14/20 at 20:56:41 probably your pulley bearing is worn out or you assembled something wrong. check out the double bearing mod. |

Title: Re: Rear Axle - right side Post by norm92de on 07/14/20 at 21:19:42 I have found that as long as I put the axle shaft back on the bike all is well. But forget to do that and all hell breaks loose. :'( |
