 WARNING 

Do not remain inside the CBC with door closed. There is a suffocation hazard. A person 

inside the CBC can exit quickly (even with the external latch padlocked) by operating the 

inside handle to open the door. 

 WARNING 

Safe loading of the CBC requires two personnel. Stay clear of the unit while lifting, as serious 

injury can result if unit swings or drops and hits personnel. 

 WARNING 

All chemical materials used in this process are flammable and toxic. Use only in well 

ventilated areas. Avoid prolonged or repeated breathing of vapors or contact with skin. 

Make repairs to fiberglass parts in a well ventilated area. Always wear breathing mask, 

gloves and eye protection. 

 WARNING 

Some environments, including desert and high temperature areas, could cause the interior of 

the CBC to reach high temperatures, causing injury or death to personnel. 

 WARNING 

The use of power sanders and grinders is prohibited. Inhalation of concentrated amounts of 

CARC paint dust by personnel can cause injury. 

 WARNING 

Possible damage to an open or improperly latched door could result from strong wind gusts or 

from heavy loading and cause injury to personnel standing nearby.

CARGO BED COVER (CBC) M105A2 TRAILER, TYPE II 0002 00 

EQUIPMENT DESCRIPTION

LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. 

The major components of the CBC are identified in Figure 1, and described in the following paragraphs. 

Upper and Lower Door Assemblies - Two separate door assemblies, upper and lower, are located on 

the aft end of the CBC. The doors can be interlocked with each other by engaging the handle of the 

upper door. This then allows both doors to be closed and opened together at the same time. The 

lower door can be separately locked in place by operating the latch on the inside. Note that the upper 

door must be open to accomplish this. An override of the latch allows the doors to be opened from the 

inside in case of emergency. 

2-Way Ventilator - A 2-way ventilator is located on road side and curb side of the CBC towards the 

forward end. The ventilators are operated from the inside. 

Folding Step - There are two folding steps located on the aft (external) end of the CBC. The steps are 

spring-loaded and extend and retract when operated by hand. The steps provide access for climbing 

on top of the CBC. Under normal conditions, the steps are retracted. 

Ladder - The ladder is a 24” folding step ladder located inside the CBC. It is secured with an 

adjustable ratchet strap assembly that is molded on the CBC. 

Chest Handle - Two chest handles are provided on top of the CBC near the aft left side. They are 

used for gripping when climbing on top of the CBC by using the folding steps. 

Access Plate - The two access plates, one on each side of the CBC, are round covers that are 

screwed onto the cable boots attached to the CBC. When loosened, the access plate is supported by a 

lanyard which is bolted from inside onto the CBC. When the access cover is open, electrical or signal 

cables can be pushed through the cable boot opening for equipment used inside the CBC. 

Door Lock - The door lock can be operated from outside or inside the CBC even if the doors are 

locked from outside. This is an override feature. In addition, the upper door can be latched with the 

lower door to provide a single function operation.

THEORY OF OPERATION

THEORY OF OPERATION

The Cargo Bed Cover (CBC) M105A2 Trailer, Type II unit is designed to be mounted on an M105A2 

Trailer which is towed by an Army vehicle. Its purpose is to carry and store equipment for use in the 

field. The CBC is suitable for worldwide transportation and storage environments, including helicopter 

airlift when mounted on an M105A2 Trailer. It is waterproof, vented, CARC painted and secure. CBCs 

are painted in either sand color or in a camouflage pattern. The CBC shell features include a non-skid 

interior floor and exterior roof, equipment mounting provisions on three walls and the roof panel. The 

aft portion of the roof of the trailer is composed of a slanted fiberglass rain hood, which is molded 

directly onto the roof. The shell is composite fiberglass, which makes it resistant to the harshest of 

environments for the life of the CBC. All attaching hardware is corrosion-resistant. A CBC installation 

kit containing the required hardware and instructions for mounting is furnished with each CBC. The 

CBC is mounted on the M105A2 Trailer using eight holes in the side panels which are drilled upon 

installation with no further modification to the trailer whatsoever. 

The CBC has two doors, an upper and a lower door, located at the aft end to gain access to the unit. 

The doors can be latched together to operate as a single door or operate separately. An override lock 

on the inside of upper door allows personnel to exit in case of an emergency. 

Additional features of the CBC are as follows: 

• Two 2-way ventilators for air circulation. 

• Two access plates, one each side, when unscrewed allow cables to be pushed through the cable 

boot opening for connecting with equipment inside the CBC. When unscrewed, the access plate 

hangs to the outside supported by a lanyard.

• A 24” ladder is stored inside the CBC and held in place by a ratchet strap assembly. It is used for 

climbing into the CBC. 

• Two folding steps, located at the aft end, when extended, provide access to the roof of the CBC. 

The steps are spring-loaded. 

• Two chest handles are located on the roof to grab onto when climbing the steps. 

• For lifting the CBC, lifting rings are attached on each corner near the top.

 Operator 

GENERAL 

Preventive Maintenance Checks and Services (PMCS) are performed to keep the CBC in good operating 

condition. The checks are used to find, correct, or report problems. Operators are to do the PMCS jobs 

keeping in mind the following guidelines: 

Before you begin using the CBC, do Before PMCS. 

After using the CBC, do After PMCS. 

If you find something wrong when performing PMCS, fix it if you can, using unit maintenance procedures. 

The right-hand column of the PMCS table lists conditions that make the CBC not fully mission capable. 

Write up the discrepancies not fixed on DA Form 2404 for unit support maintenance. Further information on 

how to use this form, see DA PAM 738-750. 

If tools required to perform PMCS are not listed in WP 0021 00, notify unit maintenance. 

INSPECTION

Look for signs of trouble. Senses help here. You can feel, smell, hear, or see many problems that can be 

eliminated before they get worse. Inspect to see if items are in good condition. Are components correctly 

installed and secured? Is any damage to the shell or components visible? Are all rubber seals tight and not 

leaking? Are all bolts and nuts tightly secured? Correct any faults or notify unit maintenance.

CARGO BED COVER (CBC) M105A2 TRAILER, TYPE II 0009 00 

PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

There are common items to check on the CBC. These include the following: 

• Nuts, bolts, washers and rivets. 

• Adhesives relating to deterioration, degradation and peeling. 

• Sealers relating to deterioration and degradation. 

• Paint relating to deterioration and peeling. 

LUBRICATION SERVICE INTERVALS

Lubricate components using MOBILUX EP023 grease or equivalent. Recommended lubrication is every 3 

months, or as required. 

CLEANING

Proper cleaning of the CBC components is an integral part of maintenance. It can help prevent possible 

problems in the future, so make it a habit to clean all CBC components whenever necessary. Clean the 

shell with a brush and mild soapy water, then let air dry. 

Cleaning of surfaces for repair/replacement parts: after removal of original parts, remove existent sealant.

MAINTENANCE ALLOCATION CHART (MAC)

INTRODUCTION

The Army Maintenance System MAC

This introduction provides a general explanation of all maintenance and repair functions authorized at 

various maintenance levels under the standard Army Maintenance System concept. 

The MAC (immediately following the introduction) designates overall authority and responsibility for the 

performance of maintenance functions on the identified end item or component. The application of the 

maintenance functions to the end item or component shall be consistent with the capacities and capabilities 

of the designated maintenance levels, which are shown on the MAC in column (4) as: 

 Unit - includes two subcolumns, C (operator/crew) and O (unit) maintenance. 

 Direct Support - includes an F subcolumn. 

 General Support - includes an H subcolumn. 

 Depot - includes a D subcolumn. 

The tools and test equipment requirements (immediately following the MAC) list the tools and test equipment 

(both special tools and common tool sets) required for each maintenance function as referenced from the 

MAC. 

The remarks (immediately following the tools and test equipment requirements) contain supplemental 

instructions and explanatory notes for a particular maintenance function. 

Maintenance Functions

Maintenance functions are limited to and are defined as follows: 

1. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or 

 electrical characteristics with established standards through examination (e.g., by sight, sound, or 

 feel.) 

2. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical 

characteristics of an item and comparing those characteristics with prescribed standards. 

3. Service. Operations required periodically to keep an item in proper operating condition, i.e. to clean 

(includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, 

chemical fluids, or gases. 

4. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting the 

operating characteristics to specified parameters. 

5. Align. To adjust specified variable elements of an item to bring about optimum or desired performance.

CARGO BED COVER (CBC) M105A2 TRAILER, TYPE II 0021 00 

MAINTENANCE ALLOCATION CHART (MAC)

Maintenance Functions - Continued 

6. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments of test, 

measuring, and diagnostic equipment used in precision measurement. Consists of comparisons of two 

instruments, one of which is a certified standard of known accuracy, to detect and adjust any 

discrepancy in the accuracy of the instrument being compared. 

7. Remove/Install. To remove and install the same item when required to perform service or other 

maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, 

repair part, or module (component or assembly) in a manner to allow the proper functioning of an 

equipment or system. 

8. Replace. To remove an unserviceable item and install a serviceable counterpart in its place. “Replace” 

is authorized by the MAC and assigned maintenance level is shown as the third position code of the 

Source, Maintenance and Recoverability (SMR) code. 

9. Repair. The application of maintenance services, including fault location/troubleshooting, 

removal/installation, disassembly/assembly procedures, and maintenance actions to identify troubles 

and restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, 

subassembly, module (component or assembly), end item, or system. 

NOTE

 The following definitions are applicable to the ‘repair’ maintenance function: 

 Services - Inspect, test, service, adjust, align, calibrate, and/or replace. 

 Fault location/troubleshooting - The process of investigating and detecting 

 the cause of equipment malfunctioning; the act of isolating a fault within 

 a system or Unit Under Test (UUT). 

 Disassembly/assembly - The step-by-step breakdown (taking apart) of a 

 spare/functional group coded item to the level of its least component, that 

 is assigned an SMR code for the level of maintenance under consideration 

 (i.e. identified as maintenance significant). 

 Actions - Welding, grinding, riveting, straightening, facing, machining, and/or 

 resurfacing. 

 

10. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely 

serviceable/operational condition as required by maintenance standards in appropriate technical 

publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul 

does not normally return an item to like new condition. 

11. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to 

 a like new condition in accordance with original manufacturing standards. Rebuild is the highest degree 

 of material maintenance applied to Army equipment. The rebuild operation includes the act of returning 

 to zero those age measurements (e.g., hours/miles, etc.) considered in classifying Army 

 equipment/components.

HOW TO LOCATE REPAIR PARTS.

1. When NSNs or P/Ns Are Not Known. 

First. Using the table of contents, determine the assembly group to which the item belongs. This is 

necessary since figures are prepared for assembly groups and subassembly groups, and listings are divided 

into the same groups. 

Second. Find the figure covering the functional group or the subfunctional group to which the item belongs. 

Third. Identify the item on the figure and note the number(s). 

Fourth. Look in the repair parts list for the figure and time numbers. The NSNs and part numbers are on 

the same line as the associated item numbers. 

2. When NSN is known. 

First. If you have the NSN, look in the STOCK NUMBER column of the NSN index work package. The NSN 

is arranged in NIIN sequence. Note the figure and item number next to the NSN. 

Second. Turn to the figure and locate the item number. Verify that the item is the one you are looking for. 

3. When P/N is known. 

First. If you have the P/N and not the NSN, look in the PART NUMBER column of the P/N index work 

package. Identify the figure and item number. 

Second. Look up the item on the figure in the applicable repair parts list work package.
