3.8.3 The geometrical and dimensional Inspection shall be in accordance with this work item, USCG
DWG. NO. 110 WPB-245-4 and ISO 484/2, Class 1.
3.9 Ring and plug gauge, test shaft kit. Prior to and immediately following all planned testing the
Contractor shall conduct a visual inspection of the GFP Ring and Plug Gauge Set and Test Shaft Kit to verify condition. The KO shall be notified immediately of any damage or missing parts including dents, dings, scratches, corrosion, or distortion of the critical test surfaces that could affect accuracy related to intended purpose.
3.9.1 If a short term storage period of less than 30 days is anticipated, the Contractor shall clean the applicable Ring or Plug Gauge with a petroleum based solvent meeting the requirements of MIL-PRF-
680 Type II, coat with a preservative in accordance with MIL-PRF-16173, grade 2, and re-stow the ring or plug gage in its designated position within the shipping container. A neutral barrier material conforming to MIL-PRF-121G, type 1, shall be applied to all wood surfaces that come in direct contact with either gauge.
3.9.2 If the contract is at its conclusion or during long term storage periods exceeding 30 days, the Ring and Plug Gauge set shall be thoroughly inspected and cleaned with a petroleum based solvent in accordance with MIL-PRF-680 Type II, and then completely coated with a preservative that conforms to
MIL-PRF-16173, grade 4 and re-stow the ring or plug gage in its designated container.
3.9.3 The Test Shaft Kit shall be packaged and packed as it was received by the Contractor after completion of each delivery order for safe storage.
3.9.4 The Contractor shall not conduct repairs to the Ring and Plug Gauge Set or Test Shaft Kit without prior authorization from the KO. The Contractor shall provide the KO with a report identifying the reason necessary for repairs, a total cost estimate and time line to complete repairs.
3.9.5 At the completion of the contract, QA personnel will inspect all GFP prior to return to the Coast
Guard. After inspection, QA personnel will report the condition of all GFP to the KO. The Contractor will be required to return all GFP to a ready for use “A” condition prior to return.
3.10 Hub bore inspection. The Contractor shall demonstrate that the finished hub bore for each propeller meets dimensional requirements by utilizing the Government-furnished plug gage referenced in 1.2 to perform the inspections outlined below.
3.10.1 Position the propeller with its bore axis vertical and the large taper uppermost. The propeller shall be supported on the bottom of its boss by a soft washer (wood, alloy, etc) with 3/4 inch minimum clearance for the plug gauge small end to pass through. The soft washer is used to protect the propeller from damage during the testing process.
3.10.2 The plug gauge shall be rigged so that it can be suspended over the bore of the propeller and dropped when required.
NOTE
When moving the plug gauge into position prior to dropping, the Contractor shall take every safety precaution making sure the GFP plug gauge is not prematurely dropped causing personal injury or damage to the GFP plug gauge.
3.10.3 Prior to dropping the plug gauge it shall be spotlessly clean and free of oil. The plug gauge shall then be evenly coated with 0.0002” - 0.0004” marking blue on the entire taper. The thickness of the marking blue shall be verified using a wet film thickness gauge.
3.10.4 The plug gauge shall be suspended centrally in the bore of the propeller with a drop distance of four (4) inches. Too much (thick) marking blue will result in an evident hydraulic bounce leaving the plug gauge free. If this happens the procedure must be repeated with a lighter even smear of marking blue until positive seating is achieved.
3.10.5 The plug gauge must be withdrawn carefully to ensure that the blue marking is not touched or otherwise marked. The hydraulic nut will be needed to break out the plug gauge.
3.10.6 Ideal contact is with blue removal contact witness markings throughout the plug gauge length. The limits of acceptability are as follows:
95% between the forward end of the propeller hub and the first oil groove with no breaks extending across the band
95% between the aft end of the propeller hub and the first oil groove with no breaks extending across the band
At least 80% of the remaining surface area
3.11 Hub bore fit. Using GFP Test Shaft, USCG DWG. 110 WPB 245-5 and the following procedure.
3.11.1 Cover the exposed threads at shaft end with nylon or P.V.C. tube and assemble propeller to dummy shaft and ensure complete contact between the conical surfaces by a light, but positive, axial force.
3.11.2 Check that the hydraulic nut is fully assembled, (i.e., gland fully compressed home into nut body).
Secure by screwing the hydraulic nut to the shaft end and screw until the gland face of the nut abuts the face of the propeller.
3.11.3 With each pump relief valve tap closed and the respective pipe to securing nut slackened; operate each pump handle in turn to vent the respective system.
NOTE
Propeller draw can be determined by measuring the distance between the propeller hub face and the fixed hydraulic nut body. “Draw” is defined as the axial distance the propeller must travel up the taper in order to affect the interference between the propeller and the shaft necessary to transmit the designed torque. Required draw is 0.182 - 0.192 inches.
3.11.4 The hydraulic nut pump should now be operated to register in the order of 1,450 – 2,900 psi. This should discourage oil from the expansion pump from leaking past the taper ends to atmosphere on initial pressurization.
3.11.5 The expansion pressure pump should now be increased gradually to 12,000 - 16,000 lbs. in a manner such that the rate of pressure on the nut is increased at the same time to 6,000 - 8,000 lbs. or until satisfactory depth is reached.
3.11.5.1 With a propeller that has been manufactured to the relevant plug gauge and shaft to the relevant ring gauge, i.e., a well-executed pressure joint, both the designed pressures should be reached at the time that the “draw” is attained.
3.11.5.2 In the event that either pump leads with a pressure rate more rapid than is necessary, it is always advisable that:
The hydraulic nut pressure rate should never exceed the relative expansion pressure rate
It should be that the expansion pressures are in advance of the nut relative pressure
Pressure required between shaft and propeller when fitting propeller is 11,600 psi (minimum)
Pressure required at hydraulic nut when propeller has taken up full draw (0.182 - 0.192 inches) to be approximately 4,440 -7,500 psi
3.11.6 The expansion pressure should now be released gradually to zero by careful control of the pressure pump relief valve tap. The above control will protect the gauge indicator pointer.
3.11.6.1 At the precise time that the pressure is released from the nut, measure the distance between the propeller hub face to the small end of the shaft taper. The acceptable distance is 0.177", +0.0944", -
0.0344” per drawing 110WPB 243-006 sheet 2.
3.11.6.2 Should no movement of the test shaft be observed after ten minutes the test is satisfactory.
Prepare the hydraulic equipment to remove the propeller. Return all plugs and caps to hydraulic connections to prevent the entry of dirt.
3.11.7 For the removal of the propeller, assuming that all preparatory work has been carried out up to the point of connecting hydraulic line proceed as follows:
Assemble hydraulic nut to shaft. Allow one thread between the propeller face and the hydraulic nut. This will allow for the shaft to be released once the pressure is put into the hub
(see next step)
Commence pumping oil into the propeller body until oil issues between boss and shaft at forward end of propeller boss. Do not exceed 25,000 psi
Commence pumping oil to the hydraulic nut until propeller is released
Following removal, all hydraulic connections shall have plugs refitted to prevent entry of dirt
3.12 Documentation. The Contractor shall conduct all measurements and tests as shown on the 110
Propeller Compliance Forms under the guidance of ISO 484/2, Class 1 (as applicable). Record and compare the measurements using the 110 Propeller Compliance Forms.
3.13 Surface finish. Surfaces of the propeller blades, fillets and hub shall be ground fair and polished in accordance with SAE J448.
3.13.1 The propeller blade surface roughness from R 0.2 to tip shall not exceed 63 micro-inches Ra.
3.13.2 Propeller hub exterior surface shall not exceed 125 micro-inches Ra.
3.13.3 Remove high spots, burrs, abrasions, nicks, corrosion, and foreign matter from propeller keyways, glands, hub bores, flanges, and mating surfaces.
3.11.4 Chase and tap exposed threaded areas.
3.11.5 Polish surfaces in way of packing rings.
3.14 Balancing. After completion of all required overhaul processes, each propeller shall be single plane balanced in accordance with MIL-STD-167-1A (Imbalance shall not exceed 7.1 oz-in). The residual unbalance in each plane of correction shall not exceed the value determined by calculating the following formula: U = 4000W/N2 where:
U = Maximum allowable residual unbalance in N-m
W = Weight of rotating part in Kg (340 kg estimated)
N = Maximum operating speed of unit (800 RPM)
Prior to performing any balance tests, the Contractor shall demonstrate the sensitivity of the balance machine using a weight determined from the following formula: Ws =
0.1(U)/r where:
Ws = Sensitivity Weight
U = Propeller Residual Unbalance Tolerance r = radial location of the weight
3.14.1 The addition of this weight shall be easily detected and discernible to the balance machine operator.
3.14.2 The mandrel or concentric rings used to support the propeller during balancing shall not exceed a total indicated run-out (TIR) of 0.025 mm (.001”).
3.14.3 Material removed to affect balance shall be taken from the suction face on as large an area as practicable and shall not approach the leading or trailing edges within (10) ten percent of the blade width.
3.14.4 Care shall be taken to assure that removal of material shall not cause the tolerances for thickness, surface contour, edge contour, width or pitch to be exceeded.
3.14.5 There shall be no machining, welding or material addition or removal to the propeller after final balance check is completed.
3.14.6 The actual amount of unbalance for each propeller shall be documented on each Final Inspection
Report.
3.15 Surface inspection. A visual inspection shall be performed on all exterior blade surfaces in accordance with USCG-SFLC Standard Specification 0740.
3.15.1 The Contractor shall perform a dye penetrant inspection over 100 percent of the blade surfaces including the hub in accordance with ASTM E1417, 2005, Standard Practice for Liquid Penetrant Testing per SFLC STD Spec 0740. Acceptance criteria per ABS Part 7, Section 10, Table 1 shall be used for evaluations. The inspection shall be performed by a certified Level II NDT Technician.
3.15.2 The Contractor shall document all propeller defects resulting from the visual and dye penetrant inspections. These defects shall be indicated by type and size on visual inspection sheets. Each propeller will require individual inspection sheets for the pressure face of the blades, suction face of the blades, the fillets, and the hub.
All visual defects, even if deemed acceptable, shall be documented on the inspection report.
3.15.3 A copy of the dye penetrant inspection report shall be turned in to the KO for review and approval.
3.16 Final inspection report.
3.16.1 The Contractor shall perform final dimensional, balancing, visual, and dye penetrant surface inspections for each repaired propeller and record this data on a final inspection report.

6.2 Appendix A.
SKID TYPE SHIPPING CONTAINER
GENERAL DESCRIPTION
The Skid Type Shipping Container is an internally reinforced wooden box consisting of two parts; a skidded base and one piece cover (hood). It is usually specified for contents up to
1000 pounds in weight and is designed to meet the following requirements: allow attachment of the item(s) directly to the skid base; provide protective shrouding of the container contents, facilitate fork lift handling, promote durability and protection through maximum reinforcement, and permit reusability for multiple shipments. The side, end, and top panels are assembled to become a one piece cover (hood) which is then lowered over the secured load and bolted to the skid base.
HOOD REQUIREMENTS
The one piece hood , consisting of the two sides, two ends, and top, shall be fabricated using nominal 2”x10” pressure treated lumber. All built-up pieces used for fabricating the sides, ends, and top shall be connected using stainless steel corrugated fasteners (3/4”x1”) spaced every 6 inches. Internal dimensions shall be calculated to allow a minimum of 2” clearance at any point between the contents and the container. The hood sides shall be reinforced on the interior with battens and diagonals using nominal 2”x6” pressure treated lumber. The hood ends shall be reinforced on the exterior using cleats. The hood shall be assembled using 12D hot dipped galvanized nails spaced approximately 3-4 inches apart. All nails that pass through battens, diagonals, cleats or other areas shall be clinched. Four lifting eyes shall be fabricated from galvanized flat bar to facilitate removal/installation of the hood. One lifting eye shall be bolted to each top corner using appropriate galvanized fasteners. Refer to
Figure 1 to view general appearance of hood.
SKID BASE REQUIREMENTS
The one piece skid base, consisting of 3 skids, 2 headers, and a load bearing floorboard shall be fabricated using pressure treated lumber. The 3 skids shall be fabricated using nominal
4”x4” lumber cut to length, beveled 45 degrees on each end to facilitate sliding when necessary. The load bearing floor board shall be fabricated using 3/4'” pressure treated plywood and two 4”x4” floor joists. The plywood shall be nailed (10-12D hot dipped galvanized nails) or screwed (2” stainless steel flathead screws) to the skids. The two floor joists shall be placed at 90 degrees to the skids and positioned as necessary at the center point of the base to accommodate the propeller load. These joists shall be through bolted to the skids using galvanized ½” carriage bolts/washers/nuts. The end headers shall be fabricated using nominal 2”x 4” pressure treated lumber cut to length. The end headers shall also be through bolted to the skids using galvanized ½” carriage bolts/washers/nuts. Refer to Figure
1 to view general appearance of skid base.
FINAL ASSEMBLY REQUIREMENTS
The propeller shall be bolted to the skid base. The Contractor and the Contracting Officer shall mutually agree on the best method to satisfy this requirement given available securing points and the criticality/protection of the hub bore finish. The cover (hood) shall be fastened to the skid base using stainless steel hex head 3/8”x 5” lag screws spaced evenly around the cover perimeter with a minimum of four lag screws provided for each side.
STRAPPING
Prior to shipment, the box shall be banded with 2 metal straps, each encircling the shipping container passing between the skids. Each strap shall be galvanized or stainless steel, ¾” wide with a minimum thickness of .023”. Each strap shall be positioned and secured within 9” of the box end.
