Apply grease approx. 1.2 g (Hitachi Motor Grease No. 29) to the shaded portion in the Front Case [10] (See
1
Fig. 6).
(Note) Be sure to apply grease to the shaded portion in the Front Case [10]. Otherwise, the spindle lock may
not work properly.
2 When installing the Lock Ring [13] into the Front Case [10], assemble so that the projections on the Lock Ring
[13] engage with the recesses in the Front Case [10]. Make sure that the flat plane of Lock Ring [13] faces
the Front Case [10] (see Fig. 6).
When installing the Carrier [15], assemble so that recess (A) on the Lock Ring [13] is aligned with projection
3
(B) on the Carrier [15] (be careful of the direction). Then make sure that the flat plane of the spindle faces the
flat plane of the Carrier [15]. If assembled in wrong direction, the flat plane of the spindle may be stopped at
the position about 2 mm lower than the flat plane of the Carrier [15] (see Figs. 7 and 8).
(Note) When assembling the Carrier [15] to the Lock Ring [13], never apply the grease between the plate of
the Lock Ring [13] and Carrier [15]. Otherwise, the spindle lock may not work properly.
