Cordless Impact Driver
Model BTD140 has been developed as the 18V version of the current 14.4V Cordless
impact driver Model BTD130F.
18V battery delivers powerful 220W maximum output, yet still extra-lightweight design
has been achieved by using 4-pole motor and Lithium-ion battery as power unit.
Features the same advantages as BTD130F as follows:
High operation efficiency
Hammer case without protrusion
Job light with afterglow function
Belt clip

[3] DISASSEMBLY/ASSEMBLY
[3] -1. Disassembling/Assembling Hammering Mechanism
Fig. 3
1) Remove Belt clip by unscrewing Screw M4x12.
After removing Bumper and Hammer case cover
by hand, then remove Rear cover by unscrewing
two PT3x16 Tapping screws. (Fig. 2)
2) Shift the tail of torsion spring from Carbon brush
onto the notch in Brush holder.
Then pull off Receptacle from Brush holder.
Now Carbon brush can be removed from Brush
holder. (Fig. 3)
3) Separate Housing (R) from Housing (L) by removing eight PT3x16 Tapping screws.
4) Remove the assembly of the Hammer case section and the Motor section from Housing (L), then separate the Hammer
case from the Motor section.
5) Attach a pair of Vise plate (No.1R041) to vise. Fix Socket 32-50 in vise securely. Then put the Hammer case section
on Socket 32-50 while fitting the hexagonal portion of Bearing box in Socket 32-50. Fit Socket 30-78 over the hex-
agonal portion of Hammer case. Then, by turning Socket 30-78 with Torque wrench shaft 20-90N.m (No.1R223) and
Ratchet head with 12.7mm square (No.1R224) clockwise, the Hammer case section can be disassembled. (Fig. 4)

6) Install Center Attachment (No.1R346) on Gear Extractor, large (1R045).
(Fig. 5)
7) Set the Gear Extractor on the Hammering mechanism (= assembled unit of
Hammer, Spindle, Spur gears, Steel balls, etc.) as illustrated in Fig. 6.
Then turn the handle of the Gear Extractor clockwise to lower Hammer to
the full.
8) Align the notch in Hammer with the top of the cam groove on Spindle.
Then take steel ball 5.6 (2 pcs) out of spindle using tweezers or a slotted
screwdriver magnetized with Screwdriver Magnetizer (No.1R288). (Fig. 7)
9) Remove the Gear Extractor by turning the handle counterclockwise.
10) Remove Spindle, Compression spring 45 and Cup washer 14 from Hammer as illustrated in Fig. 8.
Important: Be sure to lower the Hammer side so that Steel balls in Hammer cannot fall down and scatter.
11) Now Steel ball 3.5 can removed from Hammer. There are 26 steel balls in the groove on the inside of Hammer.
(As illustrated in Fig. 9, the groove is designed to have a space equivalent to one steel ball.)

[3] -1. Disassembling/Assembling Hammering Mechanism (cont.)
Do the reverse of assembling steps.
Note:
1) Assemble by piling component parts on Bearing box as illustrated in Fig. 10.
2) Make sure that twenty-six 3.5 Steel balls are in place inside Hammer.
3) Do not forget to install O ring 40 when assembling Internal gear 51 to Bearing box. (Fig. 11)
4) Internal gear 51 is not reversible when assembled to Bearing box. Be sure to assemble so that the stepped end of
the gear face Bearing box. (Fig. 11)
5) Assemble Hammer case complete to Bearing box as illustrated in Fig. 12.

[3] -2. Disassembling/Assembling Bit Holder Section
1) Put Anvil on Pipe 30 (No.1R232). (Fig. 13)
2) Put your thumb on the top of Sleeve so that Compression spring 13 does not pop out of Sleeve. (Fig. 14)
3) While expanding Ring spring 11 using Retaining ring S and R pliers (No.1R291). raise the opposite side of the Ring
spring with index finger. (Fig. 14)
4) Now the bit holder section can be disassembled as illustrated in Fig. 15.
Do the reverse of disassembling steps.

[3] -3. Disassembling/Assembling Motor Section
1) Separate the assembly of Armature and Yoke
unit from the machine.
(Refer to 1) to 4) of [3] -1. Disassembling
Hammering Mechanism.)
2) Put the assembly of Yoke unit and Armature
on a work bench so that the drive end of the
Armature touches the work bench.
Then separate Yoke unit from armature by
pressing it down towards the work bench.

[3] -3. Disassembling/Assembling Motor Section (cont.)
Do the reverse of disassembling steps.
Important:
1) Yoke unit is not reversible when assembled to Armature. Be sure to assemble so that the notch in Yoke unit is positioned
on the drive-end of Armature. If assembled wrong, the Motor section cannot be assembled to Housing (L). (Fig. 17)
2) Because Yoke unit is a strong magnet, when assembling Armature to Yoke unit, be sure to hold the commutator portion
as illustrated to left in Fig. 18. Do not hold the Armature core as illustrated to right or your fingers will be pinched
between Yoke unit and the fan of Armature that is pulled strongly by the magnet force.

3) When assembling the Motor section to Housing (L),
fit the notch in Yoke unit onto the projection on
Housing (L) (Fig. 19)
Your fingers can be pinched
