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).

 Continue by performing operations 

to 

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).
