12. Referring to Table 5.2, select the correct drill size. Use this drill
bit to check the hole diameters of the venturi inlets in the
tangential inlet ring. If the holes are worn beyond the
corresponding maximum throat diameter number shown in
Table 5.2, then replacing the venturi insert should be
considered.
13. Examine the flat faces of the base and nose cone, which form
the front and rear of the vortex chamber, respectively. Although
slight "dimpling" of the surfaces adjacent to the inlet holes is
normal, pitting and scoring is not. Clean these surfaces with
solvent if they appear oily or sooty.
14. Clean any accumulated carbon from the internal bore of the
nose cone, but do not scratch or mar these surfaces.
