IV. INSTALLATION
Install the spiral spindle by lifting and holding the pointer shaft of the Viscometer/Rheometer while
screwing the spindle onto it. The threads are left-hand so the spindle must be turned to the left. Gently
lift the chamber over the spindle up against the pivot cup until it rests over the locating shoulder.
While holding the chamber in place, fasten the assembly clamp onto the pivot cup, thereby securing
the chamber in place. The thread in this case is right hand.
See Figure 2 which shows an assembly schematic for the Spiral Adapter.

Turn on the Viscometer/Rheometer and rotate the spindle at various speeds. Observe the spiral spindle
to make sure there is no interference with steady and even rotation. If the spindle does not run “true”,

Rheometer shaft without the spindle and confirm that the rotation is steady and even.
Notify Brookfield or your authorized Brookfield agent if you experience any difficulty in performing
the above procedure.
The spiral spindle code number is 70. If you have a Brookfield digital viscometer or rheometer, which
does not contain this number, you must do the following:
