At that time the status of warranty coverage on the subsystem or component shall be mutually resolved between the Government and the Offeror. Work necessary to effect the repairs shall commence within 10 working days after receipt of notification by the Offeror.

Scope of Warranty Repairs:

When warranty repairs are required, the Government and the Offeror's representative shall agree within 5 working days after notification of a detected defect on the most appropriate course for the repairs and the exact scope of the repairs to be performed under the warranty.

If no agreement is obtained within the 5-day period, the Government reserves the right to commence the repairs.

Minimum 18.0 CFM Engine flange mounted and gear driven Integral unloader The compressor discharge hose shall be SAE 100R14A PTFE, stainless steel braid covered hose routed to a point isolated from compressor vibration and movement (i.e. to a bulkhead). Zinc plated steel, or stainless steel, tubing is acceptable if run to a component on the engine assembly.

Copper tubing of any type is not acceptable as discharge tubing directly off the compressor discharge head.

See section 3.7 for air system requirements

C4. Section 3.1.2.17 Alternator

Delete this section in its entirety and replace with the following:

If low voltage 24/28 volt DC is furnished by the hybrid drive system in lieu of a separate, mechanically driven, alternator, the following alternator is not required.

If low voltage 24/28 volt DC is not furnished by the hybrid drive system, the alternator shall be a 24 Volt Leese-Neville, Niehoff, or Delco rated to continuously supply 100% of the full-load amperage (FLA) at rated regulated output voltage with the engine at base idle speed and at an ambient operating temperature of 93C/200F. The full-load amperage (FLA) of the bus is the maximum concurrent load when all on-board electrical equipment is operating simultaneously.

Full-load amperage (FLA) and regulated voltage output shall be confirmed and validated through engineering testing and measurement under the following conditions on the first article:

at engine base idle speed all on-board electrical is operating concurrently, FLA condition at an ambient operating temperature of approximately 25C/77F

The rated output of the alternator shall be determined through analysis using manufacturer’s supplied performance data, under the following conditions:

at engine base idle speed at regulated output voltage at an ambient operating temperature of 93C/200F.

The rated output of the selected alternator shall then be compared to the FLA test data. The contractor shall confirm and validate that the contractor selected alternator meets all

Solicitation QMAE-CY-110303-N Amendment 002 PAGE 19 OF 20 requirements. The contractor shall provide detailed test plan, prior to start of test, for Government approval.

C6. Section 3.46.10 Batteries

Delete this section in its entirety and replace with the following:

Two lead-acid batteries, meeting the following requirements, shall be provided for 12/24 volt service:

Interstate No. U8D-1400BUS, or equal- 12 Volt, 450 RC min. @ 25amp @ 80 deg. F.

They shall bear an initial warranty date no earlier than 60 days prior to bus manufacture.

Positive and negative terminals shall have different size studs, or the battery terminals and cables shall be arranged to prevent incorrect installation. Battery terminals shall be located for access in less than 30 seconds with jumper cables. Battery cables shall be flexible and sufficiently long to reach the batteries in the extended tray position without stretching or pulling on any connection. Cables shall not lie on top of batteries. The battery terminals and cables shall be color-coded with red for the primary positive and black for negative.

The battery tray shall be made of stainless steel and shall pull out easily and properly support the batteries during service, filling by manual or automatic equipment, inspection of water levels, and replacement. In the normal position, the battery tray shall not be supported by rollers. A positive lock shall retain the battery tray in the normal position.

Batteries shall be easily accessible for inspection, serviceable only from outside the bus, securely mounted on a sliding or swing out stainless steel tray, treated to prevent corrosion and be readily accessible for servicing, under the bus floor and separate from the engine compartment.
