This is in a springer. Guy went in for 1st service. Didn't notice any problems starting the bike

Did they notice it when the teeth came out in the primary fluid?  Cause for concern on other 110's or do they think this was an isolated case?

[hogasm]

Tech said owner didn't notice any problems. It was found when the oil was drained.

Tech said this will be the 3rd 110 that they have replaced this year.

ps    crank end play out 8 thousands

I've been wanting a chrome starter.

Are they replacing the whole engine or the crank?

The more of these things I read the more I am glad I tore my engine down when I did.  I am also glad I am going with a 66 tooth ring gear and matching pinion for my starter.  Much stronger.

The more of these things I read the more I am glad I tore my engine down when I did.  I am also glad I am going with a 66 tooth ring gear and matching pinion for my starter.  Much stronger.

  Just because the ring gear has fewer teeth (66), does not mean it is a stronger setup.  Yes the teeth are larger on a 9-tooth pinion gear/66-tooth ring gear combination, but the 10-tooth pinion gear/102-tooth ring gear combination that came stock on your 2004 SEEG provides more gear reduction and higher torque multiplication of the starter's output.  Having less gear reduction puts more stress on the starter clutch and the reduction gears inside the starter housing, and they become the weak point.

  Tried the 9/66 combination on a built 103.  It destroyed a 1.4kw starter, a 1.6kw starter, two 2.0kw starters (all aftermarket), and shucked teeth off a 9-tooth pinion gear and a 66-tooth ring gear all in about one month.  Went back to the stock starter motor and 10-tooth pinion gear/102-tooth ring gear, and haven't had a problem in three years. 

  I hope this saves you some grief.

  If you are still set on changing your starter gears, Rivera-Primo offers a 10-tooth pinion gear/84-tooth ring gear combination that would not reduce the gear reduction as much as the 9/66 combination.

THAT SUCKS at least it's being replaced

[DCFIREMANN]

We are finding more and more of these cranks that are out .008. That seems to be the magic number. I am not surprised the MOCO replacing the entire motor. Letting a dealer tear it down and rebuild doesn't make sense money wise. I hope the people in Quality Control (yes the MOCO has them) will get to the bottom of this. I know the main reason is the pressed crank assy they are using now. For the guys that are doing the builds on their bikes have your crank assy checked if it is out have it re trued and WELDED!!!!! It will never move again.

The SAGA continues.

DAWG,

Are we talking end play or runout?

Thanks for the info.  I knew I would be increasing the torque but not the extent you described   I will stick to what I have and see how it works out.  I owe you

Not to look stupid, but how is the out of spec crank taking out the starter gear/ clutch assembly?

  Having learned this the hard way is easier to accept if I can spare someone else from doing the same.
