(g) Mount the components assembled as described in Para. (f) onto the components assembled as described

 in Para. (e). At this time, ensure that colored leadwires soldered to the Terminal [27] are properly aligned 

with relation to housing (A) and housing, (B).  (See Fig. 16)

(4) Other Precautions on Reassembly

(a) On completion of reassembly, set the Shift Knob [16] to the "H" position, and confirm that the spindle 

rotates smoothly when the Drill Chuck [8] is moved by hand.  Also, before turning the switch ON, confirm 

that the Cap [9] can be properly aligned with the clutch number positions, marked on the Housing (A),(B) 

Set [3].

Confirm that the Drill Chuck [8] rotation conforms with the setting position of the reversing switch.  When 

the reversing switch is set to the (R) side, the Drill Chuck [8] must rotate to the right (clockwise) when 

viewed from the rear (the end opposite from the drill chuck).  

Also, confirm that the rotation speed of the Drill Chuck [8] changes properly between high and low speeds

 when the Shift Knob [16] position is changed.

Check the run-out of the Drill Chuck [8].  With a  6 mm test bar (Special Repair Tool J-223-2, Code No.

305713) mounted in the Drill Chuck [8], ensure that run-out is not more than 0.5 mm when measured at a

 distance of 50 mm from the end of the chuck. 

(b) (+) Tapping Screws D3 x  8 [18] 0.59 - 0.78  Nm (   6  -  8 kgfcm,   5.2  -  6.9 In-lbs)

(+) Tapping Screws D3 x 14 [4] 0.98 - 1.5  Nm (10  - 15 kgfcm, 8.7  -  13.0 In-lbs)

FT Screw M3 x 10 [25] 0.88 - 1.1  Nm (  9  - 11 kgfcm,   7.8  -  9.5 In-lbs)

Flat Hd Screw M5 x 20   [7]    3.9   Nm (        40 kgfcm,           34.7 In-lbs)

Drill Chuck [8]    3.9  Nm (        40 kgfcm,           34.7 In-lbs)
