My apologies Idaho....when You were talking about the part numbers for the 2014 to 2019, I took that to mean that they all were part of the recall, which of course you did not say. Now with the first part of 2014 not part of the recall but from there on up being part of the recall, was there a part number change DURING 2014 as the latter ‘14’s ARE in the recall? What changed DURING 2014?
The recall should be encompassing by part number installed AND possible years / models year production, AND any pulley / sprocket that has been replaced where the affected part number sprocket / pulley has been installed. Also, the recall may affect various part numbers of sprockets / pulleys.
Posts and information indicates the number of machines that fail the initial inspection clearance check is very low. That may or may not be, since the inspection requirement does not require disassembling the parts to allow cleaning, followed by a clearance inspection with no debris limiting movement. Realize the debris particles from the fretting corrosion, are the byproduct and reduces clearances, until enough wear occurs, resulting in extreme wear.
Could it be possible that BRP / Can Am is recording the number or percentage of units found to be worn as a means to have the NHTSA recall rescinded? I am not sure if that is possible.
It will be interesting to see if Can Am does offer up a true solution. I still suspect they will have a difficult time designing a reliable pinch style or clamped replacement. Possibly they will design an exotic multi part sprocket / pulley with an elastomeric damper between the inner and outer portions (bad idea if they do).
Time will tell. No doubt they are likely testing prototypes of ideas, while lawyers are deciding the liability if failures continue, whether inspected items, replacement items or this mythical new part, or even just sucking it up, and telling all owners there is a mandatory clean and relubricate the spline task.
Would almost be comical if they retained the existing design and parts, but modified them by adding two lubrication ports and two lubricant vents, where you simply use a grease gun with proper lubricant to easily lubricate the splines without disassembly (except body panels if needed).
Kind of unrelated, but after reading about Harley Davidson losing their battle regarding proprietary equipment and software that does not allow independent shops (non dealers) to correctly work on these Spyders, plus other BRP products, these sprocket/pulley issues may be a secondary concern. Again, time will tell...
