Remove wheel and unscrew lock-ring holding sprockets in position, withdraw sprockets. Use a broad blade screw-driver to prise out the spacer (item 12) from inside the rotor (item 8). Remove rotor body (item 8), turning anti-clockwise at the same time so as to prevent pawls being dislodged. Remove pawls and springs and clean with meths or white spirit to remove old grease. Wipe out old grease from inside ratchet. Do not immerse hub in degreaser, as this will remove grease from bearings.
Assembly Procedure:
Smear a thin layer of grease around pawl locations in rotor body and ratchet in hub. Insert springs into body, carefully re-place pawls into seatings. (The grease will help to retain them). Make sure springs are located properly in pawl and body. Slide rotor body assembly onto spindle. Using a small screw-driver, ease pawls into ratchet whilst applying a gentle pressure to end of rotor body. When fully engaged rotor should spin freely in an anti-clockwise direction with the pawls clicking lightly and evenly. The rotor should lock up immediately when turned clockwise. Replace spacer (item 12) with ‘0’ ring installed. Apply a light film of grease to rotor splines and clean sprockets and refit. Replace sprocket retainer ring and tighten to required torque 40 Nm (30 ft.lb.).
NOTE: If all steel sprockets are used slight marking of the rotor body may occur but this will not impair the function of the product It is not recommended for HOPE hubs to be built radially.
