Reassembly
1. Mount the O-ring on the speed reducer .
2. Apply ThreeBond 1206C to the contact surface of the S-head and the
speed reducer . For the place to apply sealing bond, refer to “S-
head side” in fig. 7-2(b) “Surface to Apply Sealing Bond on the L-Axis
Speed Reducer” .
3. Mount the speed reducer on the S-head, and then tighten the
hexagon socket head cap screws with the tightening torque shown
in table 7-2 “L-Axis Speed Reducer Parts Checklist” .
4. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the L-arm .
For the place to apply sealing bond, refer to “L-arm side” in fig. 7-2(b).
5. Mount the L-arm on the speed reducer . Tighten the hexagon
socket head cap screws with the tightening torque shown in
table 7-2.
6. Assemble the L-axis motor , and mount the L-axis motor on the S-
head. (Refer to chapter 6.2 “Disassembly and Reassembly of the L-
Axis Motor” .)
(When replacing the speed reducer, replace the input gear , too.)
7. Mount the balancer. (Refer to chapter 10 “Disassembly and
Reassembly of Balancer Unit” .)
8. 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.
Tighten 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” (L-axis).)
9. Turn ON the power supply of the YRC1000.
For removing/applying of sealing bond and assembling after
applying sealing bond, refer to chapter 5.2 “Removing,
Applying, Assembling of Sealing Bond” .
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.
