Reassembly

1. Special attention

Reassembly can be accomplished by following the disassembly procedures in reverse. However, special attention should be given to the 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 MΩ.

(2)When replacing the Spring [85], 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 [54], ensure that it is positioned and assembled as illustrated in Fig. 46. In addition, coat 10 grams of Hitachi Motor Grease on the liner sliding portion of the Turn Table [13].

(4)When replacing the Laser Marker [107], screw the two Seal Lock Hex. Socket Set Screws M5 x 6 [103] into the Laser Marker [107]. To adjust the accuracy of the Laser Marker [107] easily, protrude the tips of the two Seal Lock Hex. Socket Set Screws M5 x 6 [103] about 1.5 mm from the Laser Marker [107] using the 2.5-mm hex. bar wrench so that Holder (B) [106] and the Laser Marker [107] become almost parallel as shown in Fig. 47-a and Fig. 47-b. Refer to "Adjustment of Laser Marker Accuracy" for adjustment of the laser marker accuracy.
