11-3. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to following items.
(1) Prior to reassembly, measure the insulation resistance of the armature, stator, switch and other electrical
components and confirm that the insulation resistance of each part is more than 5 M Ω.
(2) When replacing the Spring [77], apply 3 grams of Hitachi Motor Grease to the inner circumference of the new
spring prior to assembly.
(3) When replacing or reassembling the Liner [34], ensure it is positioned and assembled as illustrated in Fig. 66.
In addition, coat 8 grams of Hitachi Motor Grease on the liner sliding portion of the Turn Table Ass'y [26].
Position the wide collar portions as illustrated.
Liner
The raised portions of the
base must be aligned with
the joints of the liner.

(4) When replacing the Support [105], after press-fitting the Support [105] onto slide pipes (A) and (B) of Hinge
(A) Ass'y [75], drill dia. 6 mm vertical holes for insertion of the two Roll Pins D6 x 40 [116].
This process is necessary to prevent slide
