A 6 inch yellow circle with the basic vehicle classification number in black will be marked on the right side of the vehicle in a conspicuous location. The towed vehicle will be similarly marked with its basic classification number.
d) When the classification number of the vehicle is not subject to change, the marking may be applied directly on a suitable surface. On vehicles painted in gloss colours, the markings will be gloss yellow, Colour Chip No. 13538; gloss black, Colour Chip No. 17038; and gloss red, Colour Chip No. 11136. On vehicles painted in semi-gloss or lusterless colours, the markings will be lusterless yellow, Colour Chip No. 33538; gloss black, Colour Chip No. 17038 and gloss red, Colour Chip No. 11136. When the marking is applied directly to vehicles painted in the same or similar colour, the circumference of the circle will be outlined with a black circle .3/4, inch wide.
e) In usage's where the classification number may change, a sign kit will be utilised which consists of a 9 inch metal disk, a retaining plate, and two sets of five different numeral plates. By installing the retaining plate, the numeral plates will be locked in place. The sign has black numerals on a yellow background and a red C on one side of the retaining plate (figure 14).

(1) All trailers.
(2) Vehicles having a gross weight of 3
(3) Vehicles having standard classification numbers higher than 99.
(4) Vehicles having rated payloads of 3/4, to 11/2 tons. This exception does not apply to vehicles authorised for towing loads.
(5) Vehicles with fixed loads (such as tanks, self-propelled guns, etc.).
i) Front classification signs for vehicles included in h(3), (4), and (5) above will be painted directly on the vehicle. Side classification signs, where applicable, will also be painted directly on the vehicle.
j) These vehicle weight classification sign kits can be installed on vehicles in different ways. For example, in the case of Cargo Truck, M211, the sign can be installed on the brush guard, on the splash shield, or in an upright position on the fender. The choice of method is left to the using organisation.
(1) Location.
(a) The classification sign will be installed on the vehicle in one of the following locations:
1) Right front fender.
2) Right side of brush guard.
3) Right front section of hull.
4) Right side of centre front bumper splash shield.
(b) The sign will he placed below the driver's line of vision and will be positioned so that it will not block headlamps, marker lights, blackout lights, air intakes, etc.
(2) Installation.
(a) On brush guard.
1) Paint the long universal bracket (channel) with rust-inhibiting enamel.
2) After the enamel has dried, position the bracket so that the two holes in the bracket align with two bolt holes (9 o'clock and 3 o'clock positions) in the sign. Assure that the flat bearing surface of the bracket faces toward the sign. Install one bolt (1 3/4 inches long) 123798, one washer 138538, and one nut 120368. Turn nut two or three turns.
3) With the bracket in a vertical position, insert it between two bars of the brush guard at the desired location. With one hand, reach behind the brush guard and adjust the bracket to a horizontal position. With the other hand, install another bolt (1.3/t inches long), washer, and nut. Tighten both bolts, but apply only enough torque to secure the sign to brush guard. Excessive torque will cause the sign disk to bend. Figure 14 shows the sign installed on brush guard.
|
(b) On sloping fender. Install the sign as indicated in 1 and 2 below only when the slope of the fender is less than 30' from vertical. When the slope of the fender is more than 30' from vertical, install the sign in a vertical position, as outlined in (c) below, to insure readability of the sign.
1) Position the sign in the desired location on the fender and, using the sign as a template, drill two 1%2inch holes in fender to align with bolt holes in the sign at the 9 O'clock and 3 O'clock positions.
2) Install the sign to the fender with two bolts 120741 (3/4 in. long), two washers 138538, and two nuts 120368. Tighten bolts securely (figure 15).
|
1) Alter the long universal bracket (channel) in accordance with figure 16.
|
||||
3) After the enamel has dried, position the long leg of the short bracket on the back of the sign and align two holes in bracket with the two lower bolt holes in the sign.
Note. When installing the sign on a horizontal surface, position the short leg of the bracket so that it faces rearward (figure 17).
|
|
5) Position the sign in the desired location on the fender or splash shield. Bend short leg of bracket, as required, to conform to the contour or slope of fender.
6) Using the short leg of the bracket as a template, drill two 11/32-inch holes in fender or splash shield.
7) Attach the sign to the fender or splash shield with two bolts (3/1 in. long), two washers and two nuts.
8) Secure the altered long universal bracket to the sign with one bolt (3/4 in. long), one washer, and one nut. (Insert bolt in hole located between two stacks of numeral plates on sign).
9) Drill an 11/32-inch hole in fender or splash shield to correspond with the hole in the altered bracket and secure the bracket with one bolt (3/4 inch long), one washer, and one nut. Figure 17 shows sign installed on splash shield. Figure 18 shows sign installed on sloping fender.
k) Instructions for unlocking and locking the retaining plate is as follows:
(1) Unlocking retaining plate. With the thumb of one hand, press down firmly on one stack of numeral plates (figure19).
|
(2) Locking retaining plate. Assure that five numeral plates are stacked on each anchor pin with the two top plates showing the desired classification number. If the vehicle is to be used in combination, position the retaining plate so that the red C on one side of the plate will be visible. If the vehicle is to be used singly, position the retaining plate so that the red C will not be visible. Press down firmly on the top of one stack of numeral plates and slide the retaining plate onto the lock pin until the plate snaps in place. Repeat the procedure for the remaining stack of plates and lock the retaining plate to the remaining lock pin.
l) See table C for vehicle weight classification data. For vehicles not listed, or for which no similar vehicle is listed, refer to TM 5-312, only in the event that no qualified engineer is available.
