7. Disassemble the spacer bar and the unmounted frame. Use the bar as a straight edge and, with one
edge against the mounted frames tapered roller center and the other crossing the dot you drew,
draw a line crossing the dot (see "B" above). Set the bar aside.

WRAPPING THE MYLAR SPACING GUIDE AROUND THE PIPE
8. Wrap the mylar spacing guide around the pipe so that the left edge is against the transducer edge
mark (see "C" above). Arrange so that one end overlaps the other by at least three inches. Trim to fit
if necessary, but be sure not to trim at the overlapping end in order to keep it square.
9. Realign left edge of the guide with the transducer edge mark. Line up both vertical edges of the guide
and ensuring that it is snug around the pipe, mark along the overlapping edge.
10. Remove Mylar spacing guide and lay it out on a flat surface. Either, measure the exact distance
halfway between the overlap edge and the mark at the overlap, or fold the guide from the overlap
edge to overlap mark and draw a line at the fold or halfway point (see next page).
