(2) Extraction of the spindle
Remove the Retaining Ring for D32 Hole [5] which
supports the Washer [6]. By using a wooden hammer,
tap the inner cover side end of the Spindle [3] gently, then
the Washer [6], Spring (A) [9] and the Spindle [3] can be
removed. Both the Ball Bearing [7] and Rachet (A) [8] are
mounted on the spindle.
(3) Removal of Ratchet (A) [8]
Remove Ratchet (A) [8] by using a jig shown in Fig. 8.
Ratchet (A) [8] is securely press-fitted to the Spindle [3],
so a considerable amount of force is required to remove
Ratchet (A) [8]. Do not reuse the removed Ratchet (A) [8]
because the press-fitting force between Ratchet (A) [8]
and the Spindle [3] will be too low for proper operation.
