(2) Reassembly of Housing (A).(B) Set [32]
Mount the Strap [40] and housing (B) to housing (A), and secure them with the seven Tapping Screws
(W/Flange) D4 x 20 [30].
(3) Reassembly of the mechanical parts
(a) Put Washer (S) [15] onto the shaft of the Spindle [18] and mount the Hammer [11] containing the twenty-
eight Steel Balls D3 [12], Washer (J) [13] and the Spring [14] to the Spindle [18].
(b) Align the top of the cam groove on the Spindle [18] with the steel ball guide groove on the Hammer [11] as
illustrated in Fig. 11. Press down either of the raised faces of the Hammer [11] with a hand press to
compress the Spring [14] until the end surface of the Hammer contacts the flange of the Spindle [18] .
(c) Insert the two Steel Balls D5.556 [10] into the steel ball guide groove. Check that the steel balls are
properly inserted in the cam groove. Then release the hand press.
(d) Mount the hammer assembly onto the J-297 base for washer (S). With a hand press, push down the top of
the Spindle [18] to compress the Spring [14]. On this condition, mount the Stopper [16] onto the spindle
shaft and then release the hand press.
(e) Mount the Ring Gear [21], Washer (C) [22], Ball Bearing [23], Inner Cover [24], Damper [25] and the
Retaining Ring [26] to the above reassembly. Furthermore, mount the other mechanical parts and Anvil (B)
[9], then the Hammer Case [7].
(4) Mounting the Gear Box Ass'y [1] to the housing
Coat Housing (A).(B) Set [32] with Silicon Rubber (THREEBOND 1211) as shown in Fig. 7. Mount the Gear
Box Ass'y [1] so that the pinion press-fitted in the Motor [27] properly meshes with the Idler Gear Set [19].
Check that Anvil (B) [9] turns smoothly. If not, the gear meshes improperly. Check the meshing condition.
Tighten the four Tapping Screws (W/Sp. Washer) D4 x 35 [6]. Wipe the Silicon Rubber protruded from the
housing with a cloth.
