Remove five handle screws and four gear case screws from housing halves (9). Remove housing clip (16). Remove left housing halve (22). Use a T-10 bit to remove ground screw. Gently wiggle front end to separate gear case assembly (34) from pinion of rotor assembly (25). Lift stator from left housing cavity and carefully remove rotor assembly from the stator. Lift old electronics assembly out of left housing halve, paying attention to wire routing and trapping. To install new Electronics Assembly: Carefully place existing rotor (25) into stator of new electronics assembly. Place stator/rotor and PCBA firmly and squarely into corresponding channels and cavities of left housing halve (22). Insert the rotor pinion into rear of gear case assembly, meshing the gears and seating the rotor bearing. At this point install two gear case screws (9), partially securing electronics assembly and gear case assembly. Put ground screw through ground wire terminal and install onto gear case. Be sure wires and ground wire are tucked back into left housing halve. Place LED assembly, on-off switch and battery terminal block firmly and squarely into the corresponding channels and cavities of the left housing halve. Be sure all wires are routed and tucked down in channels and traps as illustrated above. Re-install speed selector slide (23) and forward/reverse shuttle (17). Carefully place right handle halve onto left handle halve. Check for any component interference or pinched wires. Re-install screws, housing clip and end cap. Check for proper functionality of on-off switch, forward/ reverse shuttle and speed selector. Install battery and check for the proper operation of tool.
