Visually inspect all other hydraulic and pneumatic hoses, check any relief valves, fittings, electrical wiring, connections, brake solenoids, and switches for corrosion, deterioration and wear of contacts. Test and adjust all the relief valves to their manufacturer's recommended pressure. 3.4.15 Structural preservation. The Contractor shall prepare and coat the hydraulic cylinder bodies, davit legs, fall tension arms, davit support bases, keel rest metal structure, winch foundation, deck sheaves and housings, cylinder mounting bases, keel support pedestal, and winch assembly in accordance with COMDTINST M10360.3B, using the coating system specified for ?Freeboard/Superstructure, Steel, Option I? in Appendix A (Cutter and Boat Exterior Paint Systems). CAUTION! Care shall be taken not to damage the polished surface of the cylinders, seals or bearings of the end pin connections. All sheaves and casings made of galvanized steel shall be mechanically roughened by hand tool instead of abrasive-blasting. 3.5 Hydraulic system flushing. After completion of all authorized system work, Contractor shall flush the hydraulic system using the system's operating fluid in accordance with the requirements specified in Section 9 (Flushing Program) of ASTM D4174. Notify the COR at least 24 hours prior to beginning flushing operation. 3.5.1 Continue flushing until the fluid entering temporary filters reaches the minimum cleanliness standard specified by the system manufacturer. NOTICE! In the absence of manufacturer?s specifications, hydraulic fluid with a particulate count of -/18/15 or better (per ISO 4406) and a water content no greater than 500 ppm (0.05% by volume) is acceptable. 3.5.2 Submit a detailed report to the COR within 24 hours, to include: Method used to obtain the particulate contamination reading. Method used to determine particle size. Final contamination level readings. 3.5.3 Drain and dispose of flushing fluid in accordance with all applicable Federal, state and local regulations. 3.5.4 After flushing, remove and dispose of temporary filters and mesh screens; renew system hydraulic filters, as applicable. WARNING! Do not operate the system hydraulic pumps, motors and other components while filled with flushing fluid. 3.6 System refilling. The Contractor shall replenish the hydraulic system with new hydraulic fluid conforming to MIL-PRF-17672 Symbol 2135 TH, through a suitable 10-micron filter. 3.7 Load testing. The Contractor shall load test the boat hoisting equipment, as follows: 3.7.1 Pre-test inspection. Prior to test, conduct a visual inspection of all hoisting fittings, slings, wire rope, rigging and test equipment. 3.7.2 Protective measures. Install TOMPKIN plugs in scuppers prior to loading the boat. 3.7.3 Safety precautions. Observe the following safety precautions, during test performance: Keep personnel out of boat during test. Keep boat low, to reduce damage, if boat drops. Do not exceed specified test weights. Avoid dynamic loading during test. 3.7.4 Test procedures. 3.7.4.1 Measure and record the weight of the MSB. 3.7.4.2 Add weight to the boat to achieve a maximum test load of 10,500 pounds, including the weight of the boat; ensure that the load is distributed with one half forward, and the other half aft, as near to the hoisting fittings as possible, in order to minimize strain on the boat. NOTICE! Weight to be added to the boat is equal to 10,500 pounds (or 150 percent of the davit?s normal hoisting load, which is 7,000 pounds) minus the measured weight of the boat. Added weight may consist of sandbags or concrete sinkers placed upon a minimum of 3/8" plywood in order to protect the boat from damage. 3.7.4.3 Lift the loaded boat by its normal hoisting equipment, and suspend for at least 10 minutes, just clear of the water, to minimize damage in case of failure of any component. 3.7.5 Post-test inspection. Upon completion of test, unload the MSB, and inspect the hoisting equipment, including the base and fasteners for Rottmer Release Gear in the boat; ensure that no parts have been unduly strained, and no welds between the deck and hoister show cracks or deformation. 3.7.6 Documentation of test results. Furnish a written report to the Coast Guard inspector within 24 hours after completion of load test. Include in the report an evaluation of all conditions found and recommendations for any repairs required. 3.7.7 Label plate. 3.7.7.1 Upon successful completion of load testing, the Contractor shall provide and imprint an anodized-hydrated aluminum label plate with 1/4" letters for each tested boat handling equipment; ensure that each plate states the following: Date of weight test. Test facility. Test load. 3.7.7.2 Permanently affix the above label plates in the vicinity of the boat davit assemblies as directed by the Coast Guard Inspector. 4. QUALITY ASSURANCE 4.1 Wire rope certification. The Contractor shall provide the COR written documentation certifying that all new wire rope assemblies have been pull tested and lubricated prior to installation. 5.
