Step 1
Move to the "Motor Drive Side" of your XD FS eBike
Goto the Tensioner Sprocket located on the lower pivot bolt and closest to the motor.
Remove the bolts outlined in the second picture with a Phillips Screwdriver and 6mm Allen Key
Gently rotate the chain guide to allow access to the tensioner sprocket

Step 2
Remove the spacers and other hardware in front of the sprocket.
Slide the sprocket off of the spindle. Note that to do this you may need to push up on the tensioner to create additional slack in the chain.

Step 3
Take the sprocket aside.
Unthread the lockring by hand. Check the threads on the sprocket and lockring to ensure they are clean and undamaged.
Reinstall the lockring on the sprocket. Get it started loosely by hand, then further tighten with a flathead screwdriver and a hammer

Step 4
You can now reinstall the sprocket onto the bike. Ensure the black face - not the lockring - is facing outwards when you do so!
Reinstall the spacers and bearing covers you removed during the installation process.
Reinstall the remaining bolts and chain guide. For the large aluminum bolt please torque this to 28Nm/20ft-lbs if you have a torque wrench to do so!
