Disassembly and assembly of final drive assembly
13. No.1 planetary carrier assembly
1) Assemble No.1 planetary carrier assembly
as follows.
a Replace thrust washers (7) and (10)
and pin (4) with new ones. (Refer to
Pin (4): 3].)
a There are remains of caulking when
the pin is inserted at the end face of
hole (h) at the side of the No.1 plane-
tary carrier. Remove the caulked
metal from the inside diameter of the
hole before starting to assemble.
1] Assemble bearings (8) and (9), fit top
and bottom thrust washers (7) and
(10) and then set the No.1 planetary
gear assembly on carrier (6).
2] Align the pin holes on the 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, rotating the
planetary No.1 planetary gear.
Take care so the thrust washer is
not damaged.
3] Insert pin (4).
a When inserting the pin, take care
so that any of the three pawls on
the circumference (Portion (f))
may not touch the thin-walled
portion on the No.1 planetary
carrier (Portion (g)).Take note,
however, that the thin-walled por-
tion is likely to be on the opposite
side of the carrier, depending on
actu al i ndiv idua l i tems. Pay
attention so that a pin pawl will
not come to the slender side of
the carrier any way. And when
traces of the groove are present,
assembly must be done avoid-
ing such locations.
