1. CONTRACTOR QUESTION: Is the YD-5500

Exhaust Bellow for the generator engine? Is the new replacement YD-

5500 exhaust bellow the same as the existing exhaust bellow? Is there existing removable and reusable exhaust insulation blankets on the generator engine exhaust pipe and bellow system? Can the Navy give us more information on the new exhaust bellow (part number, size of exhaust pipe, length of bellows, flanged bellows on each end, slip joint ends or to be welded to existing exhaust pipe system)? Is there a drawing showing the generator exhaust system?

Information pertaining to generator exhaust can be located on ‘Sheet 20’ – of reference

‘7642547 Outfitting Sketches’.

The exhaust bellow is for the generator engine.

The Navy is unsure if the new exhaust bellow will match the existing. Templating from existing material is typical for part(s) renewal. Refer to SOW paragraph 3.9.10.1 “Template exact sizes, locations, configurations, and materials from existing vessel conditions.”

Refer to the Tech Manual(s) provided.

The Navy is unsure if there is existing removable and reusable exhaust insulation blankets on the generator engine exhaust pipe and bellow system.

Can the Navy supply the part numbers and quantity of all parts needed to replace the cargo pump shaft seal?

Can the Navy supply part numbers for the new gages and remote throttle cable required?

It states to disconnect and remove the shaft assembly. Is it the Navy’s intention to just disconnect and remove the one upper shaft and the one upper shaft coupling to check and inspect the upper shaft between centers and to replace the shaft seal? Or is it the

Navy’s intention to disconnect & remove the entire gearbox and pump assembly (couplings, shafts, impellers, main discharge head) to disassemble the pump for the inspection and put between centers of the lower shaft where the seal rides?

Refer to Tech manuals and/or drawings:

‘7642545 Cargo Piping’, ‘7642547 Outfitting

On Item 3.13 through 3.13.4 - Dock and

Sea Trials; would the final dock trail of the main cargo pump diesel engine, PTO and the cargo pump be done at

Manchester Fuel Depot? Would the

Navy be responsible to fill up a cargo tank of product for the testing of the new cargo pump seal so the pump and seals won’t run dry and cause damage?

TECHNICAL REVIEW: Langham SERIAL NO: 011

Operation of the diesel engine and bump test of the pumps can be tested at contractor’s facility. The TLI’s have to be calibrated at Manchester with Fuel for a proper testing medium.
