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

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
a c t u a l i n d i v id u a l i t e m s . P a y
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.
