Perform non-destructive inspection (NDT) of the shaft taper, shaft coupling, coupling bolts, keys and keyways at both shaft ends, in accordance with SFLC Std Spec 0740. Submit CIR.

NOTE

All damage (e.g. pits, cracks, areas showing excessive wear, etc) shall be removed from each bearing journal. Renew the shaft if any pit or wear area exceeds 0.125 inches depth.

3.5.2 Shaft measurements. Prior to measuring shaft machined surfaces, eliminate all non-permanent bending/sagging from handling and storage: spin each shaft on the lathe for approximately two hours at a slow speed. For inspections and measurements, place the shaft on two precision rollers 24 inches from each end of the shaft or on lathe centers. Measure and record shaft dimensions as described below and submit a CIR:

NOTE

The shaft shall only be supported by two precision rollers (24” from each end) or on lathe centers - no additional supports (i.e., intermediary rollers, etc.) shall be used.

3.5.1.1 Measure and record the shaft key, keyway, and journal dimensions described on the forms provided at the end of this work item.

3.5.1.2 Conduct complete propulsion shaft run-out readings via dial indicator survey at the small and large ends of each taper, the fore and aft ends of each bearing position, three equally spaced locations between the bearings, and three equally spaced locations between the intermediate bearing and coupling taper, to determine straightness or any bend including magnitude and location. Each station shall be marked at the position of the maximum run-out on the periphery of the shaft. Record the run-out survey on the form (titled “Shaft Run-out Measurement Form”) at the end of this work item as part of the CIR.

3.5.2 Shaft renewal at Govt. discretion. The Contractor shall be aware that the Government reserves the right to furnish one or more new propeller shafts in lieu of working and reinstalling the existing shafts. When the Government exercises this right, the Contractor shall spin the new shaft on a lathe slowly for two hours and conduct the run-out survey of 3.4.1.2 prior to installation. Submit CFR (including form titled “Shaft Run-out Measurement Form”).

3.6 Shaft seal clean and inspect. Using Coast Guard TP 4593D as guidance and under the supervision of the tech rep, the Contractor shall:

• Hand-clean the existing metallic components using non-corrosive detergent/solvent and light abrasive pad;

• Measure and record flatness of the stern tube/shaft seal flange face with straight edge (evaluate if flange not flat and correctable to within 0.003");
