(b) Mounting Roller (A) [65]
Check the position of the smaller diameter end of the Roller Pin [66] and insert the Roller Pin [66] in the hole
of Bracket (A) [54] in the proper direction as shown in Fig. 37. Align Roller (A) [65] with the hole of Bracket (A)
[54] and press-fit the Roller Pin [66] until it becomes flush with the end surface of Bracket (A) [54] (Fig. 37).
(c) Press-fitting Bolt (A) [51]
Put Bolt (A) [51] through the hole of Bracket (A) [54] and press-fit it in Bracket (B) [56] completely (Fig. 37).
At this time, a clearance is made between Bracket (A) [54] and Bracket (B) [56] due to the dimensional
tolerance.
(d) Observe the specified tightening torque of the Lock Nut M12 [57] because it is very important for the strength.
(e) Reassembly of the bracket ass'y
(i) Mount the Return Spring [32] to the Gear Cover [33] (Fig. 38).
(ii) Mount the bracket ass'y assembled in the above steps (b) and (c) to the Gear Cover [33] hooking the
Return Spring [32] on Bracket (A) [54] (Fig. 38).
(iii) Tighten the three Hex. Socket Hd. Bolts M5 x 12 [46] with the Hex. Bar Wrench 4 mm [17] at the specified
tightening torque because they are very important for the strength (Fig. 39).
(iv) Mount the Ball Bearing 629VVC2PS2L [34] to the Gear Cover [33] (Fig. 39).
(v) Mount the two Feather Keys 5 x 5 x 10 [68] to the Cam Shaft [67]. Insert the Final Gear [47] in the proper
direction. Mount the Retaining Ring for D18 Shaft [48] to it using the stop ring pliers (Fig. 40). Apply grease
