OEM Carter Machinery noted in there quote that 3600 engine doesn’t have water bellows, can government delete this paragraph or clarify what water bellows are in need of replacing? Listed below is the response for Carter Machinery.

“7.5.26 cooling water bellows. 3600 have many water connections, none I would consider a "bellow". We reseal all connections we take off and I have not run into the bellow thing before. It being unclear we did not want to sign our name on it.”

Has this updated been made on the USNS Arctic? If so can paragraph 7.5.28 be deleted? If not can government have this work done as a CFR? Listed below is the response for Carter Machinery.

“7.5.38 Valve lubricator pump, CAT went thru a change where they were blanking these off and removing them. Sight unseen I would imagine this engine has this update. If for some reason the lubricator pump is on engine, we can take care of it thru with a CFR or something.”
