13. No. 1 planetary carrier assembly
1) Assemble the No. 1 planetary carrier
according to the following procedure.
a Replace thrust washers (7) and (10)
as well as pin (4) with new ones. (See
Pin (4): 3].)
a There is a punching mark made when
the pin was inserted on the end face
of carrier side hole (h) and the inside
wall of the hole is swelled at that
mark. Flatten the swelled part in
advance.
1] Assemble needle bearing (9) in No. 1
planetary gear (8), fit top and bottom
thrust washers (7) and (10), and then
set the gear assembly on No. 1 plan-
etary carrier (6).
2] Align the pin holes in shaft (5) and the
No. 1 planetary carrier, and install the
shaft (5) by tapping it lightly with a
plastic hammer.
a Install the shaft, while rotating
No. 1 planetary gear (8) with care
not to damage the thrust washer.
3] Insert pin (4).
a When inserting the pin, take care
that the three claws (parts (f)) on
the periphery of the pin will not
be placed on the thin-wall parts
of No. 1 planetary carrier (parts
(g)). The thin-wall part may be on
the opposite side depending on
carriers. Check each carrier and
avoid setting any claw of the pin
to the thin-wall part. If there is a
groove, avoid the groove.
a After assembling the carrier,
check that No. 1 planetary gear
(8) rotates smoothly.
a After the pin is inserted, punch
the pins (C) on the carrier at 2
locations.
