7.1.8 R V-axis ASSY (40274-2300)
Replacement part: 40274-2300
Necessary tool: Spacer (40300-M951)
1 . Open the front cover ASSY (40274-1100) (see 6.1 [p93]) .
2 . Remove the right panel (40274-M143) (see 6.3 [p94]) .
3 . Enter Wheel replacement mode and raise the R V-axis ASSY (40274-2300) to the top (see
7.1.27 [p125]) .
4 . Insert the spacer (40300-M951) between
the right processing base holder (40274-
M701) and processing chamber door
(40274-M403).
5 . Disconnect the following connectors.
1 ) CN2 of closed loop motor driver MD02 (40274-E019)
2 ) P617 (J17) of the I/O board (40274-BA06)
6 . Unscrew SB6 × 30 (n = 2) and 3PW6 (n =
2).
7 . Unscrew SB6 × 30 (n = 2) to replace the R
V-axis ASSY (40274-2300).
8 . Reassemble the parts in the reverse order.
9 . Remove the spacer (40300-M951).
10. Confirm that the R V-axis ASSY (40274-2300) operates smoothly on the hardware test
screen (see 8.1.2 [p168]) .
11 . Perform the following.
1 ) Wheel calibration (See 8.12.3 [p191].)
2 ) Groove calibration (See 8.12.4 [p192].)
3 ) Processing Adjustment (See 8.14 [p197].)
4 ) Backing up the EEPROM data (See 8.19.1 [p284].)
The spacer (40300-M951)
prevents the right processing
ASSY (40274-7000) from low-
ering by its weight.
If the spacer (40300-M951) is
not available, use a suitable
(strong) replacement with
measurements about 75 mm ×
25 mm.
