WARNING: Be sure to disconnect the power cord plug from the power supply before conducting
repair. Otherwise, the motor may suddenly turn on, posing a very dangerous situation.
1. Precautions on disassembly and reassembly
[Bold] numbers in the description below correspond to the item numbers in the parts list and exploded
assembly diagram for the Model D 13VL.
1. Removal of the drill chuck
The Drill Chuck [3] is secured to Spindle (D) [4] with the 1/2”-20 UNF right-handed screw and Flat Hd.
Screw (A) (Left Hand) M6 x 25 [1]. At first, fully open the chuck jaws and loosen Flat Hd. Screw (A) (Left
Hand) M6 x 25 [1] by turning it clockwise.
(1) Hold the drill so that only the Drill Chuck [3] rests firmly and squarely on the edge of a solid bench.
Insert a hex. bar wrench into the Drill Chuck [3]. Turn the Drill Chuck [3] until the wrench is positioned
at an angle of about 30° with respect to the bench top, and then sharply strike the wrench with a
hammer so that the Drill Chuck [3] turns counterclockwise. (Fig. 1)
If the Drill Chuck [3] cannot be removed by striking the wrench, do not strike the wrench forcibly and
try another way as described in step (2).

(2) Hold Spindle (D) [4] with an open-end wrench secured to the vise as shown in Fig. 2. Mount a pipe
onto the hex. bar wrench. Turn the hex. bar wrench counterclockwise to loosen the Drill Chuck [3].
(3) This step is only for the keyed chuck.
Secure the tip of the Drill Chuck [3] with the J-78 ring and J-78 ring ass’y (disassembly tools). Then
secure these disassembly tools with a vise to prevent from turning. Fit the J-140 wrench ass'y
(disassembly tool) to Spindle (D) [4], and turn it counterclockwise to loosen the Drill Chuck [3]. (Fig. 3)
2. Removal of handle cover (B)
(1) Loosen the Screws D4 x 20 [43] and remove Handle Cover (B) [41].
3. Removal of the brush holder
(1) Insert the tip of a small flat-blade screwdriver into the clearance between Housing (B) [35] and Click
Plate [36], and then pry the arm of the Click Plate [36] off as shown in Fig. 4-1.
(2) Lift up the tip of the Spring [39] with a small flat-blade screwdriver to release it from the Carbon Brush
[38], and hitch it on the Brush Holder [44] as shown in Fig 4-2 .Then pull out the Carbon Brush [38]
from the Brush Holder [44].
(3) Remove the Brush Holder [44] from Housing (B) [35].

4. Removal of the carbon brush
Cut the Band [37] that binds the Internal Wire [46] or [48] to the pigtail of the Carbon Brush [38] with
nippers. Then disconnect the terminal of the Carbon Brush [38] from the terminal of the Brush Holder [44],
and take out the Carbon Brush [38]. (Fig. 5)
5. Removal of gear cover (A) and inner cover (A)
Loosen the Bolt M5 x 45 [8] and remove Gear Cover (A) [9] from Housing (B) [35]. Then remove Inner
Cover (A) [13] together with the Armature [27] from Housing (B) [35].
6. Removal of the stator
Insert a small flat-blade screwdriver into the windows near the terminals and pull out the internal wires
from the Switch [47]. Tap the end of Housing (B) [35] slightly with a wooden hammer. Then remove the
Stator Holder [32] and Stator [30] from Housing (B) [35].
7. Removal of the armature
Place Inner Cover (A) [13] on a cylindrical jig and push down on the top of the pinion of the Armature [27]
as shown in Fig. 6.
8. Disassembly of gear cover (A) section
(1) Removal of spindle (D)
Remove the Retaining Ring For D35 Hole [5]. Place Gear Cover (A) [9] on a cylindrical jig of inside
diameter 38 mm or larger, and push down on the rear end of Spindle (D) [4] lightly. Remove Spindle
(D) [4] together with the Ball Bearing 6202DD [6] and Retaining Ring For D15 Shaft [79] as shown in
Fig. 7-1.
(2) Removal of the shift lever ass'y
Position the Shift Lever Ass'y [14] as shown in Fig. 7-2. Push both ends of the Retaining Ring (E-type)
for D15 Shaft [19] with a pair of long-nose pliers until a clearance about 1 to 2 mm is made. Keeping
the clearance, turn the Shift Lever Ass'y [14] by 180 degrees together with the Retaining Ring (E-type)
for D15 Shaft [19]. Insert a flat-blade screwdriver into the clearance and pry the Retaining Ring
(E-type) for D15 Shaft [19] off upward.

Reassembly can generally be conducted by reversing the disassembly procedure. However, special
attention should be given to the following items.
1. Internal wire arrangement
(1) Perform wiring of the internal wires according to Fig. 10 to Fig. 13.
(2) Be careful not to get the internal wires caught between handle covers (A) and (B).
2. Reassembly of gear cover (A) section
(1) Mount Washer (C) [20] to Spindle (D) [4] securely before mounting the Low Speed Gear [21].
(2) Mount the Shift Arm [23] and High Speed Gear [22] in the specified direction as shown in Fig. 8 and
Fig. 9.
(3) Insert the Shift Pin [15] into the slotted hole of the Shift Arm [23] securely as shown in Fig. 9.
