DUSTLESS LOADING/SELF-CONTAINED DUSTLESS LOADING SPOUTS MAINTENANCE RECOMMENDATIONS

6.9.2 Cone Support Cable Inspection and Replacement
!!! WARNING !!!
This procedure requires that the unit be moved between its retracted and extended positions.
Before repositioning the unit, ensure that all personnel are standing clear of the unit. After
repositioning of the unit, fully isolate the unit from all power sources.
Take all appropriate precautions for working on equipment suspended from overhead. Failure to
take prudent safety measures can result in serious injury or death.
1. In the retracted position, loosen the sleeve retaining bolts at the top end of the sleeve,
and remove the top of the sleeve from the tub.
!!! WARNING !!!
On dustless loading spout units with lengths greater than 8 feet, the dust sleeve
becomes quite heavy. Special handling consideration must be given to the dust sleeve
when performing this maintenance.
2. Lower the spout to the full extended position.
3. Inspect the full length of each cable for signs of corrosion or fraying. If any corrosion or
fraying is found, the cable must be replaced.
4. To replace the cable, raise the spout to a position about 12 inches from fully retracted,
and disconnect cone support cables from the attachment points inside the tub. Allow the
cones to nest within the outlet assembly.
5. Lower the outlet assembly to a position that allows easy access to the cone assembly.
6. Disconnect the cable from the outlet assembly.
7. Mark the cable at each U-bolt cable clamp, and remove the clamps from the cable. (See
Figure 3 .)
8. Transfer the marks from the old cable to the new cable.
9. Attach the new cable to the outlet assembly.
10. Attach each cone to the cable using the U-bolt cable clamps and the marks transferred
from the old cable, applying Loctite 243 (567 for stainless steel applications).
11. Lift the outlet assembly to a position at which the cables can be reattached to the
housing assembly, and reconnect the cables.
12. Lower and raise the outlet assembly, observing the cones. Each cone should nest within
the next without hanging or skewing. Each cone should suspend in a level position. If
this is not the case, adjust the cones by repositioning the U-bolt cable clamps.
13. Once each cone has been fully adjusted, fully retract the spout.
14. Push the top of the sleeve back into the tub and tighten the retaining bolts.
