(2) Reassembly of the housing section
(a) Second Pinion [28] (Fig. 32)
Before inserting the Needle [30] in the Second Pinion [28], apply grease (Nippeco SEP-3A) to the inner
circumference of the two Idle Gears [29]. Mount the Washer [31] facing its smaller diameter side to the Ball
Bearing 6001VVCMPS2L [32]. Mount the Washer [26] and then the Retaining Ring for D15 Shaft [25] using
the stop ring pliers. Press-fit the Ball Bearing 6001VVCMPS2L [32] and the Ball Bearing 609VVC2PS2L [24].
(b) Planet gear (Fig. 33)
First, apply grease (Nippeco SEP-3A) to the inner circumference of the Ring Gear [27]. Mount the pinion of
the Motor [33] to the Second Pinion [28] assembled according to the above step (a) and mount the Ring Gear
[27]. Check that the Ring Gear [27] and the Second Pinion [28] are rattling. If there is no rattle (gears are not
engaged properly), the Motor [33] will be locked. Mount this assembly to Housing (A) [2] mating the
protrusion of the Ring Gear [27] to the groove of Housing (A) [2].
