3. REQUIREMENTS

3.1. Phase I – Evaluation and Report:

3.1.1. Perform an evaluation on all six (6) machines to determine current the current condition for repair.

3.1.2. Prior to performing repairs, provide a detailed report on the status of the machines and estimated cost to repair.

3.2. Phase II – Perform maintenance:

3.2.1. Change oil and engine coolant on all six (6) engines.

3.2.2. Change oil and fuel filters on all six (6) engines. Filter conversion to new style filters is authorized and desired.

3.2.3. Replace all fuel and engine coolant hoses (including all clamps and necessary fittings) on all six (6) engines.

3.2.4. Replace all belts on all six (6) engines.

3.2.5. Replace and restore all cables with knob/handle for shutdown latch and engine stop on all six (6) engines to a fully functioning condition.

3.2.6. Replace all non-functioning gages on all six (6) engines.

3.2.7. Verify fuel control rack is free and fuel system is properly functioning on all six (6) engines.

3.2.7.1. Replace the fuel injectors on all six (6) engines.

3.2.8. Ensure all six (6) machines rotate freely (pump and motor). Machines #2 and #6 did not roll over during recent startup.

3.2.8.1. Free the pumps so they rotate. Minimize disassembly of the pumps.

3.2.8.1.1. If machines are unable to be freed in place and must be worked off-site, disconnect the pump inlet and outlet and install covers to prevent entry of foreign material.

3.2.8.1.2. Ship machines to off-site shop, free machines, then ship machines back to CNY.

3.2.8.1.3. Reinstall machines following off-site work.

3.2.9. Following completion of all maintenance and repair, perform startup service on all six (6) engines.

3.2.9.1. (G) Startup Service. A designated Portsmouth Naval Shipyard (PNSY) Representative shall be present for the startup service (to be provide upon award). A minimum of two weeks’ notice is required to schedule a date for startup service.

3.2.9.2. Troubleshoot and repair machines to facilitate startup service and validate proper operation on all six (6) machines.

3.2.9.3. If machines were removed (inlet/outlet disconnected), fill suction line with water and run machine to ensure satisfactory joint makeup.

3.2.10. Place all six (6) machines in a layup condition as follows (once shutdown/cooled down):

3.2.10.1. Remove the priming port plug and rinse pump with fresh water.

3.2.10.2. Remove the pump drain plug to drain water. Reinstall once rinsing is complete and pump is drained.

3.2.10.3. Fog the internals of the pump with corrosion coating & lubricant for pump (Note:

lubricant must meet or exceed MIL-PRF-32033 (supersedes Fed Spec VV-L-800).

Reinstall priming port plug.

3.2.10.4. Close fuel supply valve.

3.2.10.5. Disconnect fuel source by removing lance from drum, drain, bag and secure in the stowed position.

3.2.10.6. Unscrew the muffler from the exhaust manifold, secure in stowed position. Install the plug in the exhaust manifold.

3.2.10.7. Install weather protection cover with plywood support.

3.2.11. Manufacture a jacking gear to be used to roll machines over prior to starting (i.e.

after layup periods). Jacking gear is to be installed in the location of the starter on the engine. Provide installation hardware.

3.2.11.1. Install and test jacking gear on one of the machines on the day startup service is performed. Acceptance will be based on the ability of jacking gear to roll over machine and performance of the unit.

4. RESPONSIBILITIES

4.1. Contractor is responsible for the following:

4.1.1. All replacement material needed to repair the machines will be supplied by the contractor at cost.

4.1.2. Shipping and associated shipping cost if machines are required to be worked off-site.

4.1.2.1. If machines are shipped off-site, the machines must be tested once reinstalled.

This test can be included in the startup service of section 3.2.9.

4.1.3. Security: To be allowed access to the CNY, personnel must present a government contractor ID and obtain a park pass a minimum of 2 days prior to work on site. No firearms are allowed at CNY.
