BHT-212-CR&O02. Use clean, lint-free cloth or low pressure,filtered, compressed air to dry parts. Do notallow bearings to spin while drying.3. If not used immediately after cleaning,coat bearings with gearbox oil. Do not handleunoiled bearings with bare hands.4. Remove sealant from quill sleeve withplastic scraper.5. Remove paint from quill sleeve with paintremover (C-436) and rinse with clean water.6. If not used immediately after cleaning,gently agitate parts in corrosion preventive(C-105) and air dry. Apply protective coat ofgearbox oil.65-32. Conditional Inspection.0.0M._0>,r.-fNOTE

Accomplish Normal Inspection (paragraph65-33).65-33. Normal Inspection.1. Inspect parts dimensionally and replaceparts which exceed inspection limits (figure65-19).NOTEWear limits are provided to showrequired fit between mating parts. Itis not intended all dimensions bechecked as prescribed overhaulprocedure. However, parts exhibitingevidence of wear or physicaldamage shall be checkeddimensionally.2. Inspect gear (24, figure 65-17) splines forchipped, broken, or worn teeth.3. Inspect gear (24) teeth for excessivewear, scoring, scuffing, and wear pattern(figure 65-12).NOTEOvertemperature indicator dots ontemperature indicator TEMP-PLATES are of a white or light graycolor and turn black when exposedto an overtemperature condition.Chemical contamination can alsocause the indicating dots to turnblack.4. Inspect outer coupling (11) temperature(a>((DDindicator TEMP-PLATES for evidence ofo v e r t e m p e r a t u r e indication. Ifovertemperature indication is noted, performcoupling overtemperature inspection asfollows:'Z;Q_00X00ca. Inspect outer coupling cadmium platingfor being discolored (circumferential tan orlight brown band) or blistered. If cadmiumplate discoloration or blistering is found,replace outer coupling and inner coupling.b. Inspect gear teeth of outer couplingand inner coupling for being discolored(brown or blue) in the normally bright contactpatterns. If discoloration is found, replaceouter coupling and inner coupling.07(Q_Q
