and remove the load gear of the threading
roller unit (Pos. 5030A) and the detached load spring (Pos. 5030B,
Fig. 8.25). When disassembling these components, take care that the
load spring (Pos. 5030B) does not jump off.
– Remove the load gear of the threading roller unit (Pos. 5040A) and
the detached load spring (Pos. 5040B, Fig. 8.25). When disassem-
bling these components take care that the load spring (Pos. 5040B)
does not jump off.
Note:
Reassemble the load gears (Pos. 5030A and 5040A) in the
position shown in Fig. 8.26. When fitting the load gears
(Pos. 5030A and 5040A) and the load springs (Pos. 5030B
and 5040B) make sure that the spring hooks of the load
gears (Pos. 5030A and 5040A) protrude 0.5mm from the
plates of the load levers (Pos. 5030C and 5040C, Fig. 8.27).
