Chapter 6 Backup Base Section

1. Replacement of Backup Base Motor

1.1 Tightening Torque and Mounting Dimension for Backup U/D

Motor and Mechanical Lock

(1) Attach Plate 4 to Motor S23 with two bolts

with hexagon holes (M4L10), SW, and FW.

(2) Attach Mechanical Lock S22 and Pulley

S19 to the shaft of Motor S23.

At this time, confirm that the

tightening torque of the mechanical

lock is "250 kgf/cm" when the

dimension between the motor

mounting face and the bottom surface

of the pulley is "11.5 to 12.0 mm".

1.2 Confirmation of Height and Parallelism for Upper Surface of

Spline Shaft at Phase C Detection

(1) Connect the jig, release the brake, rotate the motor by hand, and detect Phase C. At

the detection position, turn the brake "ON".

(2) Regard the upper surface of Spline Shaft S16 as a reference and confirm with digital

height and dial gauges that the height of the shaft's upper surface is "232.0±0.2 mm"

from the lower surface of Base 1 and the parallelism of Points A, B, C, and D on the

shaft is "0.1 mm or less".

(3) Adjust the intermesh of Timing Pulley S20 with the belt and temporarily set up the

height of Timing Pulley S20.
