1. MAINTENANCE CONCEPT: Operators shall possess a MOS of 62F and maintenance will be per
62B MOS. This is a Non-Development Item (NDI), as such, there is no maintenance engineering effort on the part of the
Army. The level of maintenance will be assigned in accordance with maintenance policies and procedures and the
Maintenance Allocation Chart (MAC). The level of maintenance identified in the MAC should be reflective of training and
repair parts support for similar equipment in the military inventory. Unit thru depot maintenance must be considered.
MAINTENANCE PLAN: Maintenance capabilities will be governed by the MAC and will be tailored to
accommodate the complexity of the maintenance requirement.
UNIT MAINTENANCE: Unit Maintenance is performed by a crew, the operator, or unit maintenance personnel
as shown in the MAC of the appropriate TM or commercial manual. Unit Maintenance normally includes
inspection by sight and touch of easily accessible components; lubrication, cleaning, preserving, tightening
and isolation using BITE, go no-go or on board instrumentation (if applicable); and the replacement of easily
removed and installed components that do not require other than common tools.
INTERMEDIATE DIRECT SUPPORT MAINTENANCE: Intermediate Direct Support Maintenance is performed
by installation shops and selected intermediate maintenance support units and activities in the Army force
structure. Intermediate Direct Support Maintenance will remove and replace major assemblies and
components and provide contact maintenance teams for local support of unit maintenance when required.
Intermediate Direct Support Maintenance personnel shall be capable of diagnosing causes of equipment
failures, repairing specified components and repair parts so they may be returned to the supply system in
support of the clamshell bucket. This maintenance level shall maintain a supply support system which allows
unit maintenance to obtain repair parts through reparable exchange (RX) and requisitions.
DEPOT MAINTENANCE: No depot maintenance programs are planned for the overhaul of these buckets.
2. MAINTENANCE ALLOCATION CHART (MAC): (See Appendix A) Units may exceed their authorized scope and
function in the MAC when approved by the support maintenance commander.
3. MODIFICATION: Modifications will be accomplished by the end item manufacturer after TACOM approves the field
campaign or modification plan.
4. EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR): Equipment Improvement Recommendations will be
submitted in accordance with DA PAM 738-750.
5. SHIPMENT AND STORAGE: Refer to the manufacturers manual and TB 740-97-2. Packaging, handling and storage
will be IAW MIL-H-21103D.
6. DESTRUCTION TO PREVENT ENEMY USE: Refer to TM 750-244-3, and FM 5-25 for instructions
destruction of equipment to prevent enemy use.
7. BASIC ISSUE ITEMS LIST (BIIL): None
8. SPECIAL TOOLS AND EQUIPMENT: None
9. MAINTENANCE AND OPERATING SUPPLIES: See Appendix for a list of maintenance and operating supplies
required for initial operation.
