A.3 PROCEDURE
A.3.1 Shaft assembly preparations.
A.3.1.1 Preparation of shaft body areas and interfacing sleeve end prep areas. Shaft body surfaces and corresponding sleeve end prep areas shall be prepared immediately prior to application of the shaft covering in accordance with the following procedures to ensure a maximum degree of adhesion:
a. Remove any pre-existing covering, including GRP, fairing compound, and corrosion preventive paint/primer, as applicable, on the shaft body and sleeve end prep areas by mechanical means. A disc sander, Dremel tool (or equal), or suitable abrasive cutting tool may be used to score the GRP. The GRP is to then be
removed via machining with the shaft in a lathe using a blunted (bull nose) machine tool. The fairing compound can be scored with a chisel or screwdriver and chipped or peeled away as applicable. All paint/primer is to be removed utilizing a disc sander, flapper wheel, and/or wire brush.
NOTE: Water/abrasive blasting is also an acceptable method to remove any pre-existing covering. Regardless of the process utilized, exercise extreme caution not to damage the underlying shaft surface when accomplishing subject task.
b. Remove any oil or grease from the flange surfaces by solvent cleaning (using petroleum distillate type solvent in accordance with MIL-PRF-680, Type II or other solvent that provides suitable cleaning and degreasing capability without leaving a residue) in accordance with SSPC-SP 1 (see 3.1.12). Solvents shall not be ozone depleting types and shall be acceptable under local, State and Federal regulations, as required.
