VIBRATOR MOTORS

Removal, installation, parts replacement, and troubleshooting procedures for the vibrator motors
are included in Section 7.

AWD JACK MAINTENANCE

The AWD jack requires periodic lubrication and occasional adjustment of the spring plunger.
Refer to Routine Maintenance at the beginning of this section for periodic lubrication instructions.
If the ratchet action becomes noticeably imprecise or the pawl fails to latch during jack handle
movement, the spring plunger should be adjusted as follows:
1. Turn adjusting screw clockwise to
increase spring tension on plunger.
2. Move operating handle in both
directions to confirm proper
ratcheting action and pawl
engagement during jack screw
rotation.
3. If pawl does not engage jack screw
properly or ratchet action is
insufficient, repeat steps 1 and 2.

HYDROCYCLONE REMOVAL AND INSTALLATION

If desilter does not have a dedicated shutoff valve for each hydrocyclone, the desilter must be
shut down before beginning removal of any component. For desilters having a dedicated shutoff
valve for each cone (Figure 5-4), one or more cones may be removed from a cluster or manifold
arrangement without shutting down the desilter. Snap couplings allow cone(s) to be removed
without tools.
