when   you   need   it.   Telling   supply   you   need   a "whatchamacallit" for a jeep does not help, but provide them the proper nomenclature and a part number and they  can  obtain  it  for  you.  Normally  at  least  one mechanic is assigned to the repair parts storeroom for technical information and assistance. The DTO clerk provides liaison with supply for checking requisition status.  The  maintenance  supervisor  assists  supply  in determining  additional  repair  parts  requirements.  The NCF initial outfitting of repair parts is designed to support new or like-new CESE for the first 1,200 construction hours. It is based on two 10-hour shifts, 7 days per week, for the first 60 days of deployment. Levels There  are  four  different  levels  of  repair  parts support (O, G, H, or D) that can be assigned to a unit, depending upon its mission, location, maintenance capabilities, and so on. 1. 2. 3. 4. "O" LEVEL support is designed for Seabee teams,  Construction  Battalion  Units  (CBUs), Reserve battalions, and outlying NMCBs that perform only organizational level maintenance. It is the lowest level of support. "G"   LEVEL   support   is   designed   for NMCB/PHIBCB   major   detachments   that perform intermediate level maintenance. "H" LEVEL support is designed for the main body of an NMCB/PHIBCB that performs intermediate level maintenance. "D" LEVEL support is designed for major shops (CBCs) that perform depot level maintenance. Each level of support includes all lower level items; for example, "H" level includes all "O" and "G" level items. Categories of Repair Parts Repair parts can be divided into two categories: parts peculiar and parts common. REPAIR PARTS PECULIAR is composed of parts that  only  fit  a  specific  make  and  model  piece  of equipment.  When  a  unit  requests  support  for  an allowance  of  equipment,  the  Civil  Engineering  Support Office  (CESO)  identifies  the  applicable  Allowance Parts List (APL) for each make and model of equipment in the allowance. Using the APLs that are identified by CESO,   the   Ships   Parts   Control   Center   (SPCC) consolidates these APLs into a tailored repair parts list. This  list  is  referred  to  as  a  Consolidated  Seabee Allowance  List  (COSAL)  or  a  NAVSUP  Modifier  Code 98 (MOD 98 kit).  CESO  provides  copies  of  the  COSAL to  both  the  requesting  unit  and  the  Construction Battalion Center (CBC) that supports it. The CBC is then responsible for drawing the required items from stock or initiating procurement action and shipping the parts to the unit requesting the allowance. REPAIR  PARTS  COMMON  is  composed  of common  and  consumable  supplies  for  use  on  numerous types of equipment.   These items have been separated into common assemblies (MOD 97 kit) to reduce redundancy and overstocking of these items. Presently the MOD 97 kit consists of 29 individual kits, such as hydraulic hose and fittings, nuts and bolts, electrical terminals and wire, O rings, and so on. The MOD 97 kit is designed to supplement a MOD 98 kit for the first 60 days  of  a  contingency  operation.  Note that these MOD 97 kits are not designed to support a unit for a full deployment. MOD 96 provided the same support for smaller units such as details and air detachments. COSAL Arrangement Each COSAL is arranged and divided into three separate parts. PART  I  consists  of  a  cross-reference  list  to determine what APL applies to what USN number. PART I is composed of three separate cross-reference lists, each containing the same information, but sorted and printed in a different sequence. Section A is printed in USN-number sequence. Section B is in Equipment Code (EC) sequence. Section C is in APL-number sequence. PART   II   consists   of   APLs   arranged   by identification number. The APL identification number is listed in both the upper- and lower-right corner of each APL page and consists of nine digits, such as 950004121. The PART II MAJOR SEQUENCE is based on the last four digits (950004121) of the APL identification number (low to high). This is commonly referred to as the APL number. Exceptions are vehicles, such as truck-mounted water distributors (one APL for the truck, another APL for the distributor) and mobile cranes (one APL for the carrier, another for the crane.) The PART II MINOR SEQUENCE is based on the preceding three digits, such as 950064121 for the fuel system  group  items.  A listing of groups covered in each APL is displayed on the first page of each APL, such as 1-19
