Put rotor (21) in stator (22).Using thickness gage as shown,measure clearance between rotorand stator. If clearance is morethan 0.005 inch, replace rotorand stator.d.Inspect end cap (15), stator(22), rotor (21), spacer plate(18), and housing (41) forcracks, distortion, scoring, ordamaged threads. Replace part ifany of these conditions areseen.e.Check for rough areas on ends of stator (22), rotor (21), machined surfacesof housing (41), end cap (15), and spacer plate (18). Smooth rough areasusing 600 grit abrasive cloth. Put abrasive cloth on a flat surface that isas flat as a piece of glass. If abrasive cloth is new, move a piece of steelacross abrasive cloth six times to remove sharp pieces of grit. Move partacross abrasive cloth six times. Check if rough areas have been removed.
