521D, 621D, 721D transmission calibration
Transmission Clutch Calibration
Clutch Calibration ensures the most optimum shifting
of the transmission. Before doing the following
transmission clutch calibration procedures make
sure of the following:
1. The machine is running and the transmission oil
is warm.
2. Engine low idle speed is correct.
3. The transmission is in neutral.
4. The park brake is applied.
5. If steps 1 through 4 have been accomplished,
calibrate the transmission clutches as follows:
A. Put the transmission in the manual shift mode
and the gear selector in 3rd gear neutral.
B. Press the program/reset switch to program.
C. Press the up/down count switch to up count
until the display reads 011.
D. Put the program/reset switch in the OFF
(center) position.
E. Press the up/down count switch to up count
twice, so the display reads 02.
F. 2 00 00 will begin to flash in the display center.
G. After one second, the Clutch Calibration Main
Code status will be displayed in the 3rd and
4th spaces (2 XX 00, the XX represents the
3rd and 4th spaces).
H. The Modulation Cycle Number will be
displayed in the 1st and 2nd spaces (2 00 XX,
the XX represents the 1st and 2nd spaces).
I. During Clutch Calibration, the Clutch
Calibration Main Code will change from 01 to
07 as the process is completed. Code 07
indicates that the calibration process is
complete and the information center will return
to normal working status.
J. If any of the Clutch Calibration parameters are
incorrect, the display center will stop flashing
and display a code in the 1st, 2nd, 3rd, and
4th spaces.
If this occurs, the code in the 3rd and 4th
spaces will be a Clutch Calibration Main Code
09 through 14 and indicate what process the
calibration was in when it was aborted
The 1st and 2nd spaces will produce the
Clutch Calibration Sub Code, which is the
code that informs the operator of the reason
the process was aborted.
K. After completing the Clutch Calibration
procedure, turn the machine OFF for 15
seconds. This sets the calibration in the
controller.
