(2) Apply silicone rubber (ThreeBond 1211) to Housing (A) [35] as shown in Fig. 16. Mount housing (B) to
housing (A) and secure them with seven Tapping Screws (W/Flange) D4 x 20 (Black) [32]. Wipe the silicone
rubber coming out of the housing with cloth. Insert the Sleeve [45] into the Strap (Black) [44] and tighten the
Machine Screw (W/Washers) M4 x 25 [46].
(3) Mounting the mechanical parts
(a) Mount Hammer (E) [12] containing the twenty-eight Steel Balls D3.175 [13], Washer (J) [14], Hammer
Spring (C) [15] and Washer (S) [16] to Spindle (E) [18].
(b) Align the top of the cam groove on Spindle (E) [18] with the steel ball guide groove on Hammer (E) [12] as
illustrated in Fig. 7. Press down either of the raised faces of Hammer (E) [12] with a hand press to
compress Hammer Spring (C) [15] until the end surface of Hammer (E) [12] contacts Spindle (E) [18].
(c) Insert the two Steel Balls D5.556 [11] 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 Spindle (E) [18] to compress Hammer Spring (C) [15]. On this condition, mount the Stopper [17] onto
the spindle shaft and then release the hand press.
(4) Mounting the hammer assembly to the housing
Raise the housing assembled in step (2) and mount the hammer assembly to the housing being careful of
proper engagement between the Idle Gear Set (2 pcs.) [19] of the hammer assembly (check that Washer (E)
[22] is mounted on Spindle (E) [18]) and Ring Gear (C) [21]. After mounting, check that the hammer
assembly turns. If the hammer assembly does not turn, the gears engage improperly.
(5) Mounting the hammer case
Put Anvil (C) [10] on Spindle (E) [18]. Cover it with the Hammer Case [8] and secure with the four Tapping
Screws (W/Sp. Washer) D4 x 25 (Black) [7].
(6) Mounting Guide Sleeve [4]
Insert the two Steel Balls D3.97 [9] into the hole of
Anvil (C) [10]. Mount the Guide Sleeve [4], Guide
Spring [3] and Retainer [2] in sequence. Mount
the Retaining Ring [1] into the groove of anvil
using J295 jigs (A) and (B) for retaining ring as
illustrated in Fig. 15.
(NOTE) Be sure to replace the Retaining Ring [1]
with new one because the Retaining Ring
[1] may be deformed at disassembly and
the Guide Sleeve [4] may come off if the
deformed Retaining Ring [1] is used again.
