9.4. MOUNTING OF DLT CASE AND TORQUE TUBE SUB-ASSEMBLY (FIGURE 24)
The case mounting direction for which the coupling has been made may be identified as follows:
When the case is mounted and coupled to the torque tube (without torque arm or displacer), the tip of the conical pin (53) is
aligned with one side of the oval hole in the flexure (59).
Left mounting: see figure 24a
Right mounting: see figure 24b
For installation, reverse the procedure outlined for removing a DLT case and torque tube sub-assembly (section 9.3). It is
recommended that new gaskets (143 -149) be used when installation is performed (see figure 22).
NOTE: If the coupling does not match the mounting direction, verify that the screw (62) is loose and pin
(72) is free to rotate in the
coupling end of the beam
(54) before hooking the displacer on the torque arm (135).

in Section 9.5, unless the instrument is already prepared and calibrated for the specific application required by the customer. In
such a case, however, it is recommended to check the adjustments of the specific gravity meter function, adjusting screws, and
the calibration, before putting the instrument in service.
CAUTION:
The following procedure is valid only if the coupling between beam and torque rod has already been
adjusted for the required mounting direction (see Section 7.1).
