8-3. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to the following items.
(1) Check that the internal wires are wired and arranged properly as shown in Fig. 17 to Fig. 22.
(2) Insert each internal wire into the grooves of the Housing Ass'y [27] <26> securely and be careful not to pinch
the internal wires when mounting the Handle Cover [35] <30> and the Tail Cover [51] <49> .
(3) If degradation is found on the grease inside the Gear Cover Ass'y [8] <8> at reassembly, remove the grease
and apply 30 g of new grease to the inside of the Gear Cover Ass'y [8] <8> . Applicable grease is Nippeco
JF-375 (Code No. 930036). Apply it to the Second Pinion and Gear Set [10] <10> , tooth portion of the
Armature [15] <15> , needle bearing of the Inner Cover [12] <12> and the inner circumference of the metal.
(4) When replacing the Dust Seal [25] <25> and the Ball Bearing 608VVC2PS2L [9] <9> , be careful of the
mounting direction of the Dust Seal [25] <25> so that the convex side faces the ball bearing and the concave
side faces the commutator. When press-fitting the Ball Bearing 608VVC2PS2L [9] <9> , be careful of the
press-fitting load. After press-fitting, check that the Ball Bearing 608VVC2PS2L [9] <9> rotates smoothly.
The Dust Seal [25] <25> is an important element to protect the Ball Bearing 608VVC2PS2L [9] <9> from dust.
Be sure to mount the new Ball Bearing 608VVC2PS2L [9] <9> after disassembly.
