9-2. Reassembly
Perform reassembly in the reverse order of disassembly while observing the given precautions and taking care of
the following points.
(1) To make reassembly easier, coat grease on the Steel Balls [11], [18], [19].
(2) Reassembly of the Change Lever [13]
With a flat-blade screwdriver or similar tool, move the Clutch [38] and the Reciprocating Bearing [40] so that
the claw (protruding portion) of the Reciprocating Bearing [40] and the claw (protruding portion) of the Clutch
[38] are in contact.
After inserting Spring (H) [10] and Steel Ball D3.97 [11] into the recessed portion of the Gear Cover [7], apply
grease to the pin portion of the Change Lever [13] into the Gear Cover [7] so that it is positioned midway
between the "Hammer" mark and the "Drill" mark. Be careful that should the mounting position of the change
lever be incorrect, it will deform the claws of the change lever.
(3) Reassembly of the Oil Seal [14]
Prior to reassembly, apply grease to the inner circumference of the Oil Seal [14]. However, do not apply
grease to its outer circumference. Also, when press-fitting the Oil Seal [14], ensure it is straight and level.
9-3. Lubrication
Apply special grease (N.P.C. FG-6A, Code No. 980927 is recommended) to the inner and outer circumferences of
the Piston Pin [31] and Piston [30], O-Ring (A) [29] mounted on the Striker [28], O-Ring (B) [26] mounted on the
Second Hammer [25], the Reciprocating Bearing [40], the Reciprocating Bearing [40] mounting portion of the
Gear Shaft Set [35], the O-Ring (I.D.10.5) [27] and the clutch-claw portions of the Cylinder [20], the inner
circumferences of the metal inside the Inncer Cover [33], and external grooves of the Clutch [38]. Also, without
fail, insert 70 g (0.15 lbs.) of special grease inside the Gear Cover [7].
