About this file
This Performance Work Statement (PWS) is for the repair of a Detroit Diesel engine (6V71/53) from a hydraulic test stand at Seymour Johnson Air Force Base. The key objectives are to obtain a fully functional and reliable engine that meets original equipment manufacturer (OEM) performance standards. The contractor must pick up the engine from Building 2115, transport it to their maintenance facility, replace multiple defective components (including specific gaskets, seals, and filters), reseal the cylinder head, perform a dynamometer test to verify 210 horsepower at 2800 RPM, and deliver the repaired engine back to the base.
The scope of work includes detailed specifications for component replacement, comprehensive dynamometer testing (checking tune-up, compression, cooling system, lubrication system, fuel system, and air intake), and adherence to strict operational parameters. The contractor must coordinate pickup and delivery with the Aerospace Ground Equipment (AGE) shop, maintain security protocols for base access, follow all safety regulations, and provide a post-repair report. The warranty requires the repaired engine and replaced components to be free from defects for a minimum of 500 hours of operation from the date of final acceptance.
