Otherwise, Steel ball 4.5 (a) may move from the place
where it should bes, and it is difficult to join Gear
assembly of rotor side to that of Drill chuck side.
See Fig. 14.
3. While turning Gear assembly of Rotor side,
so that Spur gear 13 complete ( j ) can engage
with the gears in Gear assembly of Chuck
side, insert the protruded portion of Rear
housing (s) to Front housing.
See the left photograph in Fig. 15.
