1. Main Frame Assembly and Engine Compartment

a. Inspect for and repair rust and corrosion damage, dents, body damage, broken/defective braces and mounts, hinges, latches and hardware. Replace damaged, missing or deteriorated insulation and compartment door weather stripping. Interior compartment and exterior body corrosion control will be applied and painted with original OEM paint

(paint color may be specified by the government). Inspect and replace all damaged, weathered or cracked hoses. Replace main hood hinge with stainless steel if not already done so.

2. Instrument Panel Assembly

a. Operational test and evaluate instruments. Replace all defective gauges, switches, and circuit components. Repair corrosion damage. Perform console interior corrosion control.

Replace damaged or corroded wiring, connectors and terminal strips. Ensure connections are clean, bright and tight.

3. Wiring Harness, Lights, Circuits, and Connections

a. Operational test, evaluate and repair all wiring harnesses, circuits and connections. Repair or replace all corroded components (e.g.: lights diode blocks, timers etc.) Replacement wiring and components will be marked and conform to OEM wiring schematics and diagrams.

4. Seat, Tracks, and Mounting Hinge

a. Repair or replace seat, seat tracks, and seat mount hinge. Tears in seat fabric or excessive corrosion/rust or damage will require seat replacement.

5. Steering System, Articulating Joint, Hoses, Valve and Cylinder

a. Operational check, evaluate and repair steering system, articulating joint, hoses, valves and cylinders. Check/repair component corrosion.

6. Scrubber Head Assembly

a. Check/repair head lock hook system, pins, bushings and springs for defects and corrosion. Remove scrub head, disassemble and inspect deflector, brush motors, bushings and idler bearings. Replace squeegee and brushes. Check all components for defects, wear and corrosion. Check and adjust system operation upon re-assembly.

7. High Pressure Washer System

a. Perform high-pressure washer test. Check hydraulic and water system for proper operations. Adjust and replace defective components to restore system to original manufacturer’s specifications. Apply necessary corrosion control.

8. Brake System/Wheel and Hand Brake Assemblies

a. Remove wheels, inspect pads. Inspect/replace wheel bearings as needed. Inspect and reseal hydraulic drive motors if needed. Remanufacture brake calipers. Flush system and install stainless steel rotors if needed. Inspect mechanical handbrake system and tires for wear. Perform preventative maintenance to prevent rust and corrosion on all system components.

9. Main Hydraulic Pump

a. Check pump for full power operation and damage. Replace or overhaul if found defective or damaged. Inspect, repair all linkage from pedal to pump valve, adjust linkage to insure no creep in neutral. Check springs, bearings and ball joints for defects, rust and corrosion.

Repair or replace defective components.

10. Vacuum System

a. Inspect/Repair vacuum fan to meet original factory specifications. Check bearings, housing, mounts and hydraulic motor for defects or corrosion.

11. Water and Solution Tanks

a. Inspect water and solution tanks for damage. Inspect all hoses for wear, weathering and defects. Replace all defective/missing inspection door gaskets. Prepare recovery tank surfaces for corrosion control Belzona Liner. Coat internal surfaces and test.

12. Hand Wand and Dual Hose Kit Assemblies

a. Inspect all components for damage and weathering. Check all rubber hooks, holding brackets and components for damage and wear. Replace all missing or defective parts.

13. Rear Vacuum Squeegee Assembly

a. Inspect rear vacuum squeegee assembly. Test raise and lower cylinder for proper operation and leaks. Inspect all components for wear, damage and corrosion. Evaluate extent of mainframe corrosion. Replace all bearings, bushings and castors if needed.

Change out blades if more than two edges are worn.

14. Hydraulic System Components

a. Operational test of hydraulic system and components, check and adjust pressure of components as needed. Replace filters and fluid.

15. Engine Assembly and Components

a. Operational test engine for proper rpm, power out, excessive smoke and running temperature. Inspect fuel system for leaks, damage and corrosion. Inspect water pump and bearings. Pressure test coolant system. Change out all fluids and filters. Check charging system. Replace belts and hoses. Conduct compression test. Repair or replace defective engine peripheral components found during test/inspection.

Note: Statement of Work does not include full engine replacement. Units requiring complete engine replacement will be furnished by the government via the QEC Naval Supply System.

Normal Flight Deck Scrubber overhaul turn around time is not to exceed 12 weeks from date of delivery.

Government representative reserves the right to inspect all flight deck scrubbers prior to, during, and after completion of contracted repairs at vendor’s location.

Government furnished transportation will deliver and pick-up within fifty (50) mile radius of Naval
