Disassembly.NOTEIf hanger is being disassembled forreplacement of part(s), instead ofoverhaul, disassemble only to extentnecessary.1. Remove retainer ring (1, figure 65-2),plate (2), and spring (3) from outer coupling(8).2. Remove nut (16), washers (5), bolt (4),and retainer plate (6).65-5. Cleaning.NUMBERC-304C-436MATERIALS REQUIREDcowNOMENCLATURESolvent0Paint Remover1. Wash all parts, except bearings, withsolvent (C-304). Dry with filtered, compressedair.2. Clean bearing by wiping with dry, lint-freecloth. Do not allow bearings to spin whiledrying.3. Remove paint from hanger with paintremover (C-436). Rinse with clean water.N(a(CDNOTEFor ease of maintenance, blockouter coupling to remain in outboard(extended) position. This willstabilize outer coupling duringdisassembly and assembly.3. Slide rear coupling (15) from splined shaft(11). Remove inner and outer couplings (7and 8) from forward end of splined shaft.Remove seal (10) from outer coupling (8).3A. Observe condition of grease. If greaseis very viscous (thick) and has a strongpungent odor, replace outer coupling (8) andinner coupling (7).°`2°4. Support inner race of bearing (13) andpress out shaft (11).5. Remove retainer ring (12) and pressbearing from hanger (14).6. Discard bearing at overhaul.((DD3-O65-6. Conditional Inspection.000(Do0-oNOTEIf records or physical appearance ofhanger indicates component wassubjected to an accident or incidentoutside realm of normal usage,perform Conditional Inspection asfollows. If no evidence is found,accomplish Normal Inspection,paragraph 65-7.-`a?-`(n30:c1. Visually inspect curvic faces of outer andrear couplings (8 and 15, figure 65-2) fordistortion or evidence of overheating.lfoverheat conditions are noted, refer toparagraph 65-7.2. Visually inspect mounting ears of hanger(14) for cracks or distortion.3. Visually inspect teeth of spherical faces ofinner and outer couplings (7 and 8) for cracksor galling.(n04. Check bearing (13) for freedom andsmoothness of rotation.65-00-00Rev.3 Page 7I
