Reassembly - Hitachi C 12LSH Technical Data And Service Manual

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 [152], 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 [98],
ensure it is positioned and assembled as
illustrated in Fig. 65. In addition, coat 8 grams of
Hitachi Motor Grease on the liner sliding portion
of the Turn Table [26].
(4) When replacing the Laser Marker [198], screw the two Seal Lock Hex. Socket Set Screws M5 x 6 [200] into
the Laser Marker [198]. To adjust the accuracy of the Laser Marker [198] easily, protrude the tips of the two
Seal Lock Hex. Socket Set Screws M5 x 6 [200] about 1.5 mm from the Laser Marker [198] using the 2.5-mm
hex. bar wrench so that Holder (B) [207] and the Laser Marker [198] become almost parallel as shown in Fig.
66-a and Fig. 66-b. Refer to "11-10. Adjustment of Lase Marker Accuracy" for adjustment of the laser marker
accuracy.
