6.2 Disassembly and Reassembly of the L-Axis Speed
Reducer
• Refer to fig. 6-2(a) “Disassembly and Reassembly of the L-Axis
Speed Reducer” .
 Disassembly
1. Turn OFF the power supply of the YRC1000.
2. Disconnect the internal wiring harness from the S-head.
(Refer to chapter 8 “Cable Wiring” .)
3. In order to prevent the L-arm from falling, the L-arm must be supported
by using a chain block, etc. before removing it.
4. Unscrew the hexagon socket head cap screws and , and then
remove the L-arm from the speed reducer .
5. Remove the L-axis motor , and then remove the input gears , ,
and .
(Refer to chapter 5.2 “Disassembly and Reassembly of the L-Axis
Motor” .)
If the speed reducer is removed without removing the L-axis motor,
an external force will be applied to the shaft of the motor, causing the
shaft to bend or causing damage to the motor.
6. Unscrew the hexagon socket head cap screws , and then remove
the speed reducer and O-ring from the S-head.
 Reassembly
1. Mount the O-ring on the speed reducer .
2. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the S-head, and then mount the speed reducer on the S-
head. For the place to apply sealing bond, refer to fig. 6-2(b) “Surface
to Apply Sealing Bond on the L-Axis Speed Reducer” . At this time, be
careful so that the O-ring does not come off.
3. Tighten the hexagon socket head cap screws with the tightening
torque shown in table 6-2 “L-Axis Speed Reducer Parts Checklist” .
4. Reassemble and mount the L-axis motor.
(Refer to chapter 5.2 “Disassembly and Reassembly of the L-Axis
Motor” .)
(When replacing the speed reducer, replace the input gear, too.)
5. Apply ThreeBond 1206C to the contact surface of the speed reducer
and L-arm, and then mount the L-arm on the speed reducer . For
the place to apply sealing bond, refer to fig. 6-2(b) and fig. 6-2(c)
“Surface to Apply Sealing Bond on the L-Arm on the Other Side of the
L-Axis Speed Reducer” .
6. Tighten the hexagon socket head cap screws with the tightening
torque shown in table 6-2.
7. Tighten the hexagon socket head cap screws with the tightening
torque shown in table 6-2.
8. Mount the internal wiring harness.
(Refer to chapter 8 “Cable Wiring” .)
