4.  Remove the two screws from the receptacle that needs replacing (Figure 5). 

   

 

Figure 5: Column Receptacle Screws 

 

5.   Remove the receptacle from the molded column tube using a small flathead screw driver, if 

necessary. 

 

6.   If replacing the Short Molded Column Tube, carefully disconnect the feed waste 

manifold harnesses and the product manifold harness from the motherboard using pliers 
to pull the white connector off of the pins and away from the motherboard (Figures 6 
and 7).  Then remove the tube from the Feed Waste Manifold using a small flathead 
screw driver (Figure 9).
