6.2 Disassembly and Reassembly of the L-Axis Motor
• Refer to fig. 6-3(a) “Disassembly and Reassembly of the L-Axis
Motor” .
 Disassembly
1. Mount the fixing jig of the L-axis, and fix the L-arm so that it does not
rotate by using the fixing jig. (chapter 4 “L-Axis Fixing Jig” )
2. Discharge grease.
3. Unscrew the hexagon socket head cap screws , and remove the
cover .
4. Unscrew the hexagon socket head cap screws and , and
remove the support .
5. Remove the encoder connector of the L-axis motor (fixing bolt:
pan-head screw M2), and then disconnect the encoder cable.
6. Turn the connector on the cable side of the power connector for the L-
axis motor , and then disconnect the power cable. If the connector
does not turn, remove the connector by holding the connector on the
cable side with a pair of plastic pliers, etc.
7. Mount the brake releasing devices, and release the brake.
8. Unscrew the hexagon socket head cap screws , and insert the stud
bolts M6 (length: 30 mm or more) into the tapped hole M6 (4 places)
on the motor flange face. Screw the stud bolt so that the clearance
between the motor and the contact surface is 5 mm or more, roughly.
9. Remove the L-axis motor horizontally from the S-head. Be careful
not to damage the oil seal in the S-head at this time.
10. Unscrew the hexagon socket head cap screw , and then remove
the shaft , key , gear , shaft , and pipe .
DANGER
• Execute disassembly and reassembly of the L-axis motor after
mounting the L-axis fixing jig on the balancer.
Also, be sure to confirm that the L-axis is firmly fixed by releasing
the L-axis motor brake.
Failure to observe this leads unexpected L-arm rotation at the
moment when the L-axis motor is removed and it may result in
damage to machinery or death or serious injury.
• For fixing the balancer, refer to chapter 4 “L-Axis Fixing Jig” .
CAUTION
When removing the motor from the L-arm, a lot of grease comes out
from the outlet of the motor.
Make sure to protect peripheral equipment in advance.
