HW1485471
 Reassembly
1. Mount the O-ring on the shaft , and then apply ThreeBond 1206C
to the contact surface of the speed reducer and the shaft .
2. Mount the shaft on the speed reducer by using the hexagon
socket head cap screws , and then tighten the screws with the
tightening torque shown in table 7-1 “S-Axis Speed Reducer Parts
Checklist” .
3. Apply ThreeBond 1206C to the contact surface of the base and the
speed reducer . For the place to apply sealing bond, refer to "Base
side" in fig. 7-1(b) “Surface to Apply Sealing Bond on the S-Axis
Speed Reducer” .
4. Mount the O-ring on the speed reducer , and mount the unit
(including the speed reducer and the O-ring ) on the base.
5. Tighten the hexagon socket head cap screws with the tightening
torque shown in table 7-1.
6. Mount the cover by using the GT-SA bolts , and then tighten the
GT-SA bolts with the tightening torque shown in table 7-1.
7. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the S-head. For the place to apply sealing bond, refer to “S-
head side” in fig. 7-1(b).
8. Mount the S-head on the speed reducer .
9. Tighten the hexagon socket head cap screws with the tightening
torque shown in table 7-1.
10. Apply ThreeBond 1206C to the contact surface of the S-head and the
gear unit, and then mount the gear unit on the S-head by using the
hexagon socket head cap screws . Tighten the screws with the
tightening torque shown in table 7-1.
11. Assemble the S-axis motor , and mount the S-axis motor on the
S-head.
(Refer to chapter 6.1 “Disassembly and Reassembly of the S-Axis
Motor” .)
(When replacing the speed reducer, replace the input gear , too.)
12. Mount the internal wiring harness. (Refer to chapter 9 “Cable Wiring” .)
13. Remove the hexagon socket head plugs from the grease inlet and the
grease exhaust port, and then replenish grease (Molywhite RE No.00)
from the grease inlet. Mount the hexagon socket head plugs on the
grease inlet and the grease exhaust port after the replenishment of
grease. (Refer to chapter 5.1.2 “Grease Exchange Procedure” (S-
axis).)
NOTE
For removing/applying of sealing bond and assembling after
applying sealing bond, refer to chapter 5.2 “Removing,
Applying, Assembling of Sealing Bond” .
NOTE
If grease is filled before the sealing bond is solidified, it may
cause grease to leak.
After tightening the screws, leave it 30 minutes or more, and
then fill with grease.
