NOTE : Be sure to insert the correct end of the center
compression nut into the bulkhead body. The thread 
has been partially relieved on the bulkhead side of the 
center compression nut to visually identify its 
orientation. (Fig.13.) 
Figure 13.
 
 
 
 
 
NOTE : Excessive tightening of the center compression nut is
not necessary to form a good seal around the tube 
and may damage the O-ring, the seal housing tube, or 
the threads of the compression nut. 
NOTE : Make sure the seal housing tube is all of the way into
the center compression nut while you are tightening 
it. 
 
c Again check that no part of the seal housing tube comes in contact 
with the moving differential components. Less than 8mm [5/16”] 
should be considered too little clearance. Gently bend the tube 
away from moving parts if necessary.
