Disassembly1. Turn OFF the DX100 power supply.2. Remove the GT-SA bolts , then remove the cover .3. Remove the plastic cover on the connector (signal) of the internalwiring harness connected to the R-axis motor . Then, connect thebackup battery. (Refer to chapter 2 “Notes for Maintenance”.)4. Remove the plastic cover on the connector (power) of the R-axismotor . Then, disconnect the connector (signal, power) of theinternal wiring harness connected to the R-axis motor .5. Remove the GT-SA bolts . Insert stud bolts M6 (length of the threadpart: 40 mm or more) in the tapped holes M6 (2 holes) on the M-base . Screw the stud bolts in until the gap between the motor andthe matching surface becomes 10 mm or more. Then, remove the M-base from the casing.6. Remove the hexagon socket head cap screw , then remove theshaft , the speed reducer , and the washer .7. Remove the GT-SA bolts . Then, remove the R-axis motor fromthe M-base . Reassembly1. Mount the R-axis motor on the M-base .2. Tighten the GT-SA bolts with the tightening torque shown in Table5-4 "R-Axis Motor Parts Checklist".3. Fill the hatched area of the oil seal shown in Fig. 5-4 “Disassemblyand Reassembly of R-Axis Motor” with Harmonic grease SK-1A.4. Apply ThreeBond 1206C on the matching surface between the shaftand the R-axis motor . Then, mount the shaft , the speedreducer , and the washer on the R-axis motor .5. Apply Loctite 242 to the thread part of the hexagon socket head capscrew . Then, tighten it with the tightening torque shown in Table 5-4"R-Axis Motor Parts Checklist".6. Apply ThreeBond 1206C on the matching surface between the M-base and the casing. Then, mount the M-base on the casing.7. Tighten the GT-SA bolts with the tightening torque shown in Table5-4 "R-Axis Motor Parts Checklist".8. Connect the connector (signal, power) of the internal wiring harness tothe R-axis motor , and remove the backup battery. Then, put theplastic cover on the connector.9. Apply ThreeBond 1206C on the matching surface between thecover and the casing. Then, mount the cover with the GT-SAbolts .10 911134485 6 72 141 421151 56 7 184 4319 91045 of 96
