 Reassembly
1. Mount the key on the L-axis motor . (The key is provided
with the L-axis motor .)
2. Apply ThreeBond 1206C to the contact surface of the L-axis motor
and the shaft , and then mount the shaft , shaft , gear ,
and pipe on the L-axis motor .
3. Apply LOCTITE 243 to the thread part of the hexagon socket head cap
screw , and then tighten it with the tightening torque shown in
table 6-2 “L-Axis Motor Parts Checklist” .
4. Apply ThreeBond 1206C to the contact surface of the L-axis motor
and the S-head, and then mount the L-axis motor on the S-head
while being careful not to damage the oil seal in the S-head.
For the place to apply sealing bond, refer to fig. 6-3(b) “Surface to
Apply Sealing Bond on the L-axis Motor” .
5. Apply ThreeBond 1206C to the hexagon socket head cap screws .
Tighten the screws with the tightening torque shown in table 6-2.
6. Connect the encoder cable to the L-axis motor , and then tighten
the connector fixing bolt (pan-head screw M2) with a tightening torque
of 0.2 N•m. (The connector fixing bolt is provided with the connector.)
7. Insert the power connector to the L-axis motor by aligning the key
position as shown in fig. 6-3(c) “Motor Power Cable” , and then turn
the coupling nut on the cable side until it makes a clicking sound.
Confirm that the arrow marks on the connector on the motor side and
the connector on the wiring harness side match.
8. Mount the support , and then tighten the hexagon socket head cap
screws and with the tightening torque shown in table 6-2.

screws with the tightening torque shown in table 6-2.
10. Replenish grease (Molywhite RE No.00) from the grease inlet.
(Refer to chapter 5 “Notes on Grease Replenishment/Exchange
Procedures” .)
11. Disassemble the L-axis fixing jig. (chapter 4 “L-Axis Fixing Jig” )
