Replacement sprocket for the permanent fix is not yet available and cannot be ordered.......The currently available part number is NOT the final fix
Something's not adding up to my way of thinking.
Part # 705503239 is the currently available sprocket, according to the BRP parts catalog.
The catalog shows that 705503239 was used starting in Sept 2020. That means it was not used in 2020 models.
2014 and 2020+ models apparently do not have a fretting problem.
The part number changed from 2014 (705501986) to 2015 (705502134) so who knows what changed in the material used?
According to the BRP parts catalog the *2134 sprocket was used up to Sept 2020.
If there was a significant difference in the sprocket material from 2014 to 2015 was that the cause of the fretting? If so, why don't we see reports of fretting with the 2020 models and why are they not included in the recall?
That's why, as I stated in another thread, I'm thinking the output shaft may be the cause of the fretting. But if so, then why don't we see reports of fretting with the 2020+ models since the output shaft part # is the same from 2015 to 2022? Or did they (or Rotax) make a change in the output shaft in 2020 without changing the part #?
My observation has been that quality control over documentation has not been one of BRP's strong points. Maybe one of the reasons they are taking so long to come up with the permanent fix is there have been material or manufacturing changes in the sprocket or output shaft that were not identified by part # changes. Maybe they simply do not know what sprocket material is in the sprocket of every Spyder since 2015 and so have been unable to pinpoint the root cause of the fretting. And if they don't know the root cause, there is no way to define the fix.
All of the above emanates from my years working in quality assurance where I came up with the following mantra; QA-QA-QA -- The Questioning Approach of Quality Assurance leads to the Quintessential Answer!
