The Army Maintenance Management System (TAMMS) Users Manual

Legend for Figure 5–1;
completion instructions follow.
1. TUBE SERIAL NO. Enter the cannon tube serial number. TM 9–1000–202–14 shows where tube serial numbers are on cannons. For
the 106mm Recoilless Rifle, enter the assembly serial number here.
2. CANNON TYPE, MODEL OR SERIES. The cannon type, model series, 105mm, M68, for example, or 155mm, M185, goes in this
block.
3. ORGANIZATION (UIC). Owning organization name and Unit Identification Code (UIC). Pencil entry only.
4. SPECIAL LIFE DATA. Enter special life data on the specific weapon. Use this space to record EFC round life and other tube life information,
when needed. Note any maintenance to be pulled on a round-fired basis (pencil entry). For the 106mm Recoilless Rifle, use this
space to keep a total round count on the installed vent. For the 105mm, M68 Gun, compare the remaining EFC life of the breech mechanism
assembly to the remaining life of the gun tube in column 10h. If the EFC life of the breech assembly is less than the entry in column
10h, print in column 10g, “Do not exceed (whatever the remaining breech mechanism EFC life is).”
5. END ITEM IDENTIFICATION. Enter the weapon end item identification, type series and model. For example, Howitzer, Medium,
towed, M198 or Tank, Combat, M1A1. Also enter the end item chassis serial number in this block.
6. RDS/EFC COMPUTATION. Enter equivalent full charge (EFC) factors for various rounds here. TM 9–1000–202–14 gives EFC factor
values. Write the zone figures above the sub columns in column 10g.
7. CANNON SERIAL NO. Enter the cannon serial number. TM 9–1000–202–14 shows where the cannon serial numbers (breech ring)
are.
8. RETUBINGS. Divide this block into 2 sections by drawing a diagonal (slanted) line from the upper right to the lower left corner. In the
first section, enter the number of times the installed breech ring has been retubed. See TM 9–1000–202–14 for details. If the initial tube
is in the breech ring, enter a zero in this section. In the second section enter the total EFC rounds for the breech mechanism, for the
105mm, M68 Gun. For other equipment, in the second section, enter the total cumulative EFC rounds fired on the end item at the time of
the last retubing. This figure is the total rounds on the whole system, the chassis or carriage, for overhaul.
9. REBUSHINGS. Enter the number of times the installed breech ring has been rebushed. For the 106mm Recoilless Rifle, enter the
number of times the breech ring has been revented. Leave this block blank on weapons that do not require rebushing or reventing.
10. This block is divided into 10 columns, a through j.
Date a. Write the calendar date when the action occurred. For example, 14 Aug 83. Do not use Julian dates.
Projective Type b. Enter the type of projectile and cartridge model.
Zone or Charge c. Enter the charge and zone number. Leave this column blank when it does not apply to weapons.
Rounds Fired d. Write the number of rounds actually fired.
EFC RDS Fired e. Multiply the rounds fired in column d by the EFC factor value for that type round or propellant.
Cumulative RDS Fired f. Add the number of rounds fired in column 10d to the last entry made in column 10f.
