I just bought a 2015 RTL with 45,000mi on it. It looks and runs like new, but when I was digging around with the search feature here, and on a few other sites, people talked about some failures due to the plastic oil pump gears.
Previously, people have had them fail at around 35k or less.
Should I crack open the cover and replace them as preventive maintenance at this point? How many miles does everyone have on theirs?
Plastic gears ........... or nylon gears?
I assumed they were plastic. You know what they say about assumptions. I'm speaking of the OEM gears.
We've only seen failure due to improper service installs (usually water pump related). Not to say that they don't fail naturally. Just not sure how concerned we should be about it?!
I have 87.5K+ on mine with no problems whatsoever with anything related to the engine and only one warranty repair item, parking brake motor replaced under factory warranty. My B.E.S.T. extended warranty expired unused.
Well that makes me a little more comfortable. Thank you both for your replies
Both of the issues referenced in this link were 998 V-Twins. Not sure this relates meaningfully to the 1330 motors.Quote:

I haven't owned my Spyder long enough to have any history on the nylon gears but I do know that they were used by GM in some of the car engines (cam shaft sprocket - metal hub with a nylon running surface) to provide for a quieter running timing chain. Yes they did wear but I didn't experience any failures with the teeth chipping or breaking off even with 5500-6000 RPM in a drag race.
Agree but still plastic, not beyond reasonable would continue to use on new enginesQuote:

Simply an idea.
