INSTALLATION

Tools Required:
8 mm Allen key

1. Slide the drive-side crank arm onto the motor spindle, making sure the splines are correctly engaged.
2. Thread the crank bolt in by hand, then tighten using an 8 mm Allen key. The crank arm should draw smoothly onto the spindle.
3. Install the non-drive-side crank arm, ensuring it is positioned 180° opposite the drive-side arm.
4. Tighten both crank bolts to 50 Nm using a torque wrench.
5. Check that both crank arms are fully seated and rotate freely without contacting the motor housing or frame.
