Note: Retaining ring WR12 is firmly seated in the groove of Armature shaft, and the groove is so small that
the ring cannot be removed with a pair of commercial retaining ring pliers only.
Therefore, slip the gap of the ring outside of the groove using 1R004 or 1R291, then remove the ring

Armature through Yoke unit in advance.
Note: Yoke unit is not directional when assembled with Armature.
2. Without enough care, Ball bearing 6001DDW on the drive-end of
Armature may often be incompletely seated in the bearing room of
Inner housing. Therefore, fit the bearing completely into the bearing
room in Inner housing while carefully turning Armature by hand
to engage the gear of Armature shaft with Spiral bevel gear 26 in
Inner housing. Then fix the bearing with Bearing retainer and two
M4x12 Hex socket head bolts.
Note: Be sure to apply adhesive (ThreeBond 1321B/1342 or Loctite

complete parallel to Vise. (Fig. 33)
O-ring case is moved toward the top of Tool holder (guide) complete, and therefore, Ring spring 28 can be relieved
from O-ring case.
(5) Using a slotted screwdriver, tap Ring spring 28 through the two access holes alternately to push them out of the inner
groove of Tool holder (guide) complete. (Fig. 33)

[3]-8. Swash bearing 10, Gear section
Fig. 37
Note: This step can be done without removing Motor section.
(1) Remove Gear housing complete as per top left drawn in Fig. 27.
(2) Remove Inner support complete by loosening two M4x25 Hex socket
head bolts with 1R170. (Fig. 37)
(3) Remove two M4x12 Hex socket head bolts that is seated on Bearing
retainer B on Inner support complete. (Fig. 38)
(4) Remove Swash bearing 10 portion and Piston cylinder portion from
Inner housing. (Fig. 39)
(5) When Ball bearing 606ZZ is left in Gear housing complete after
removing Swash bearing 10 section, insert Cam shaft into the hole of
Ball bearing 606ZZ and tilt Cam shaft back and forth (Fig. 40), then
tap Gear housing complete with a plastic hammer as drawn in Fig. 41.
Ball bearing 606ZZ can now be removed.
(6) Put Spiral bevel gear 26 on a U-groove of 1R139 as shown in Fig. 42, then press down Cam shaft using 1R281
to loosen the press fit of Cam shaft to Spiral bevel gear 26, Ball bearing 608ZZ and Ring 8 at a time. (Fig. 42)
Also Clutch cam, Swash bearing 10, Sleeve 9 and Bearing retainer B can be removed from Cam shaft in this step.
(Fig. 43)
(7) By removing Retaining ring S-7 from Cam shaft using 1R291, Compression spring 7 and Spur gear 10 can be
removed from Cam shaft. (Fig. 43)

(1) Onto Cam shaft, slide Swash bearing 10, Sleeve 9, Spiral bevel gear 26
in order, then press-fit them using 1R032 and1R033.
(2) Slide Bearing retainer B onto Cam shaft in advance, then press-fit
Ball bearing 608ZZ then Ring 8 onto the shaft; be careful not to fix
Bearing retainer B between the bearing and Spiral bevel gear26.
(3) Onto Cam shaft, slide Super gear 10 and Compression spring 7 in order,
then secure them with Retaining ring S-7 using 1R291.
(4) Mount Guide plate then Piston joint to Piston cylinder. (Fig. 44)
(5) Fit Compression spring 14 over the boss of Inner housing. (Fig. 45)
(6) Insert the pole of Swash bearing 10 through the hole of Piston joint,
then mount Swash bearing portion into Inner housing.
Secure Swash bearing portion by fixing Bearing retainer B to Inner
housing with two M4x12 Hex socket head bolts. (Fig. 46)
Note: Be sure to apply adhesive (ThreeBond 1321B/1342 or Loctite 242)
to the threads of the two M4x12 Hex socket head bolts.
