Question No. 28: Optional Items O-86 and O-87, Propulsion Shaft bearings, paragraph 3.3.1 and 3.3.2; The referenced CG Dwg 378 FRAM W-244-2 indicates that the bearing staves are brass backed rubber staves that are no longer available. NSTM chapter 244 and NAVSEA Dwg 803-1385664 were not supplied.

Paragraph 3.3.1 indicates that the shafting sleeves will be undercut yet there is nothing in the specification indicating this will occur.

Questions;

USCG will supply the missing references upon award of this requirement. For bidding purposes, assume oversized Thordon staves will be required. Actual stave sizes will be determined from shaft liner measurements.
