3.5.3 Flushing acceptance criteria. The Contractor shall flush each loop until the following cleanliness criteria is maintained for a 2-hour period.
3.5.3.1 Differential pressure. Differential pressure increase of less than 2 psig higher than the differential of a clean filter bag can be maintained for a 2-hour period.
3.5.3.2 Visual inspection. Visual inspection of all contaminants (solid, solid-based, and nonsolid) collected from the filter bag and magnets after the end of the 2-hour collection period indicates that the sum total volume of particles shall not exceed the volume of a U.S. dime (10-cent piece). The filter bags and strainer magnets shall contain no more than five solid or solid-based contaminants, no one greater than 1/64 inch in any direction. The filter bags and strainer magnets shall contain no non-solid contaminant larger than 1/16 inch in any dimension except for hairlike particles which can be up to 1/8 inch long.
*Solid-based contaminants are defined as particles which cannot be crushed between the thumbnail and finger.
3.5.3.3 Particulate count. Fluid contamination levels do not exceed NAS Code 1638 -Class 9 for the duration of the 2-hour period.
- The flushing process duration begins when the oil is within and maintains the specified flushing temperature (170° to 180° F) and flowrate (260 gpm). Temperatures and flow rates shall be maintained for the duration of the flush.
- During flushing, the system shall be manually shocked or vibrated using soft mallets or mechanical vibrators to dislodge contaminants within the piping.
- Filter bags and cartridges shall be changed as needed to maintain a differential pressure increase of no more than 5 psig over the differential pressure of a clean filter bag.
- Rotate the engine crankshaft (for internal flush sequences) through 90 degrees travel at 20 minute intervals.
3.5.4 Sequence flush.
3.5.4.1 Heat a quantity of clean flushing oil, equaling 60 to 70 percent of sump capacity, to a temperature of 170° to 180° F.
3.5.4.2 Circulate the oil throughout the lube oil circuits in the following increments, confirming secure connections prior to each next incremental increase:
- 20 gpm;
- 75 gpm;
- 260 gpm (not to exceed 120 psi).
3.5.4.3 Flush each lube oil system loop for a minimum of 12 hours.
3.5.4.4 Continue flushing each loop until the cleanliness criteria of Para 3.5.3 is maintained for a 2 -hour period for applicable loop.
3.5.5 Ancillary components.
3.5.5.1 Disconnected instrumentation lines. Flush all disconnected gage and pressure switch lines using flushing oil or compressed air.
3.5.5.2 Jumpered components and equipment. Hand clean all components and piping (both removed and blanked) not flushed during the flushing process. Inspect condition of all components and piping. Submit a CFR.
3.5.5.3 Lube oil cooler.
3.5.5.3.1 Disconnect and remove the lube oil cooler assembly and transport it to the shop.
3.5.5.3.2 Soak the cooler in cleaner bath for 4 hours to remove any dirt or sludge build up and then clean the cooler.

3.5.5.3.4 Reassemble the cooler using new gaskets, O-rings and lantern ring.
3.5.5.3.5 Reinstall the cooler assembly on the engine using new gaskets and O-rings.
3.6 System restoration. Upon completion of engine flushing, accomplish the following:
3.6.1 Drain flushing oil from sump, piping, filter and strainer housings, placing flushing oil in suitable containers. Dispose of all removed oil.
note
1) Every effort shall be made to remove flushing oil from the lube oil system, to including removal of oil sump screens and wiping the sump clean with lint free rags. This will ensure a satisfactory test for viscosity, which will eliminate the need to change oil after a few hours of engine operation.
2) Careful use of clean low pressure air (100 psi or less) may be used to blow flushing lube oil back to the engine sump through the filter and strainer housings.
3.6.2 Clean and inspect lube oil sump using lint-free rags. Clean and inspect internal lube oil pump suction piping from the suction bell mouth or strainer to the pump inlet.
3.6.3 Restore lube oil system to original configuration in preparation for engine run.
note
Ships Force will reinstall all engine filters and replenish oil upon satisfactory completion of all system restoration.
3.7 Engine run after flushing completion. The Contractor shall be present during testing of the MDE (s) to ensure satisfactory flushing was accomplished.
- Coast Guard personnel will operate all shipboard machinery and equipment.
- Contractor shall take caution and monitor the differential pressure across the strainer and filter during engine operation. Ensure the differential pressure does not exceed bypass valves set point. If the strainer or filter requires repeated cleaning to maintain proper differential pressure, the entire flushing procedure shall be repeated.
- Some debris is expected during engine operations for various reasons (i.e. internal engine components that cannot be 100% flushed, potential overhaul/repair work accomplished concurrently with flushing, vibrations created by engine operations, etc). Engine run-in should continue, monitoring pressures and filter contents, to ensure residual debris is filtered by the installed system before making official determination regarding efficiency of the flush. Immediately stop all engine run-in procedures if evidence of substantial debris (i.e. metal shavings, large contaminates, etc) are discovered that could be indicators of potential issues.
