If original cadmium plating on sleeve shimplate (20, figure 65-10) has worn through,replate as follows:oa. Cadmium plate sleeve shim plate usingbrush cadmium plating solution (C-108).Required dimensions shall be met afterplating.b. If original sleeve shim plate is missingor mixed With other shim plates, determinerequired dimensions of replacement shimplate as follows:Oc(1) Examine sleeve for referencedimension which is metal stamped or vibroetchedon sleeve adjacent to applicablemounting surface.(2) Subtract 0.3915 to 0.3910 in.(9.9441 to 9.9314 mm) from dimensionscetched or stamped on sleeve to give requiredshim thickness, after plating.(3) Grind new blank shim to requiredthickness and apply brush cadmium platingsolution (C-108). Using etching ink orequivalent, identify shim plate by etchingserial number of applicable sleeve on shimplate. Also etch thickness on shim plate.Neutralize with water and common bakingsoda after etching.8. Repair sleeve (18) as follows:a. If damaged or loose, replace clinchnuts (19).(1) Use a drift or bolt threaded into nutto drive clinch nut out; being careful not todamage hole in sleeve flange.(2) Clean sleeve by vapor degreasingwith 1.1.1-trichloroethane (C-334).Lfi5-00-00Page 33
