Yamaha Vino 125 Starter Clutch Replacement 

Clarifications and Corrections: This is an extremely helpful video, first. But it could have used an edit to correct a few things that could lead to headaches, including one missed maintenance step and one major dis-assembly that goes too far for most situations. I’ve outlined a few places where more information is helpful and to make his vocabulary mesh with actual Yamaha part names. Clarifications: 14:13: “First the nut comes off then there’s a - this washer” which he later calls “big thick guy.” That’s the one-way clutch on Yamaha parts fiches. The next part, a dished disc with “fins” visible is the fixed sheave. 15:13: The “small ring” he takes off next is a spacer between that fixed sheave and the next smooth dished part, the “primary sliding sheave.” (Some tuners get rid of this spacer to bring the sheaves closer, allegedly to alter the position of the belt and get more start-up torque.) 15:40: MISSED MAINTENANCE ITEM: “There’s a small cone that you have to need to grab and pull with you…because it is a P-I-A to figure out how to get all this back in there.” No, it’s not, but yes, take it out whole. But you MUST lift off that rusty cam (that he calls ‘cone,’), which serves as a back cover of the sliding sheave. It holds weighted rollers that he mentions (later, he becomes confused about how to put them back). Be VERY diligent about recording their orientation in their tracks of the sheave before removing them to inspect them for any flat spots. These rollers get ‘hurled’ outward by centrifugal force as the sheave spins, and it’s crucial that they do so smoothly and evenly. Look for flat spots on their surface and if they have any sign of that, Replace them for about $10 (or if you’re a tuner, get custom ones that are slightly lighter and alter how and when the sheave grabs the belt.). Clean the sheave and cam and make sure there are no burrs, pits, etc. that could affect the roll of these weights. (Put the weights in the sheave and tilt the part and you’ll see how they roll out to the edge) OVERKILL?: 16:16: “There’s two parts to this part and you want to buy them together” is not quite reight. You can get them separately, though many parts outlets sell them together as one "assembly." “This part” is the problematic Starter Clutch that is the goal of this repair. The one behind it is the Starter Wheel (right now locked in place by the idler wheel). Unless the Starter Wheel has stripped or broken teeth or a pronounced wobble, it’s probably just fine. It’s much stronger than the clutch assembly, so when push comes to shove, it’s the clutch that fails, not this heavy wheel. His looks factory new. So, save the $$ here and don't risk stripping bolts to remove the idler gear to get at the starter wheel. (Caveat: You may HAVE to buy the clutch/starter wheel together from some parts outlets. If so, your call on whether to use only one part of it or go ahead and pull the starter wheel by pulling off the idler wheel. Those bolts are TIGHT and easily stripped). STOP/PAUSE DISASSEMBLY and turn your attention to the starter clutch itself. 16:27: “This thing - there’s the problem, there” YES. But it’s worth freezing this frame to take a close look because he moves on quickly in his quest for the starter wheel. This is a spring-roller clutch, made to allow movement one way, but impede it in the other. That barrel roller that falls out? It’s supposed to spring back and forth to either allow or impeed the clutch's rotation. It’s worth looking carefully at these three spring mechanisms on the interior ring of the clutch assembly. Yours may not be so bad that the barrel falls out, but you may find that one or more of the barrels/rollers gets stuck and doesn’t spring back into place and/or is heavily scored. Do this to confirm that this was your problem part. (You also can remove them, clean and dry lube them, and see if that solves the problem). See: : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nRVaVJ4xx7s.html WHILE YOU”RE HERE: You’ve done this much labor, so it’s really worth looking at the other side of the belt drive, the clutch or ‘clutch carrier assembly.’ Removal is basically two (tight) nuts, the innermost of which is 1.75 inches wide or wider (I think about 41 mm). They’re both stubborn, but it’s worth seeing how much surface you have left on your clutch, and/or replacing it before putting the drive side of your bike back together again. It’s the most expensive part, around $112, but if it fails, you basically are doing all this disassembly again, and buying another gasket probably.

Thanks for the content

So nice

Great video - saved me a lot of time. Just be sure to put the big case gasket in place BEFORE putting the belt on the pulleys!

Sorry, I think I missed somewhere, What year is the Vino.? overall, for the clutch replacement vin. little edit here and there, chop snip. there or so, would be perfect, thanks for sharing ..If you so happen to inspect your belt remember it is directional, arrows point to towards variator. if warn bad, replace or just reference your belt slopping.

Lay your scoot on the right side on the lawn and no need to deal with any oil what so ever! Just be careful to not get any debris in the 2 ports that are revealed once you remove the clutch cover.

Hey just curious what size belt you use? I have a 2004 vino 125 thanks for your help!

Was your starter motor spinning the drive belt at the time of the problem? My Riva is having issues starting (initially I thought it was the Bendix, but the starter motor spins the belt, so I'm not sure now..?)

Just got one of these Vino scooters, a late 2001. It has the same starter whine as in the vid but does it when it's cold and/or hot start attempt which it just spins. Starts on a kick start. So, if it spins with this whine, it's the starter clutch and not the starter? Shoulda watched this vid b4 I went and bought a starter motor assy.

Hello, do you remember where you got the starter clutch from?

Hi man. Have the same sound when i press the start button haha ibhope it is the same which ia the starter clutch needs replacing and not the starter motor?

So did it start up hot ? I have the same issue with a riva 125.
