Dry vs. Wet Torque, Thread Locker & Wrench Selection
All values are dry torque. Oil drain plug is wet-threaded — use a new crush washer every oil change. Greased pivot assemblies use the lower end of each range — confirm free rotation. Medium-strength thread locker on sprocket bolts, disc bolts, caliper bolts, and flywheel nut. Clutch hub nut requires thread locker plus staking. A 10–80 Nm click-type wrench for most service; compact 5–25 Nm wrench for DOHC low-torque fasteners. Calibrate all tools annually.
