Why spline lubrication?
« on: November 19, 2025, 04:11:56 AM »
Especially BMWs seems to require spline lubing of the clutch shaft splines as well as final drive splines. But we never hear this about cars. Well, at least I do not. Anybody know what this is required (more) on bikes than cars?
Current bikes:
2018 V9 Roamer
1982 XV750/1100 mongrel
1990 XT600Z
2001 NT650V in bits

One thing is that automotive driveshaft splines are in an oily environment

 The lube is more to inhibit corrosion than to provide lubrication.
