3-21 REAR IMPACT GUARD SYSTEM

Vehicle standards FMVSS No. 224, Rear Im-

pact Protection, requires all 334 Series trailers

manufactured after January 26, 1998 to be

equipped with a rear impact guard certified by the

manufacturer as meeting FMVSS No. 223, Rear

Impact Guards. The guard, or bumper,

(See Fig-

ure -)

, meets the following requirements:

minimum of 4 inches vertical height

extend laterally to within 4 inches of the

sides of the trailer

ground clearance of no more than 22

inches

placed no more than 12 inches from the

rear of the trailer.

capable to deflect 5 inches.

The standard also specifies minimum force and

energy absorption requirements for the guard. A

DOT decal certifies that the guard meets FMVSS

No. 223 and 224 standards. The decal is placed

and must remain at all times

on the forward fac-

ing surface of the guard, 12 inches inboard of the

curb side and of the guard.

See Figure -

for loca-

tion of decals.

Replace any component that does not allow

the above minimum requirements to be met. Any

hardware that holds the rear impact guard and be-

comes damaged or becomes loose shall be re-

moved and replaced. The 3/4" grade 8 screws that

hold the bumper energy pack shall be loctited and

torqued to 280 ft.-lbs.

DANGER

ALWAYS CHECK THE CONDITION OF

THE REAR IMPACT GUARD SYSTEM.

IF GUARD SYSTEM HAS BEEN DAM-

AGED, IT MUST BE REPLACED. FAIL-

URE TO MAINTAIN GUARD SYSTEM

MAY RESULT IN INJURY OR DEATH

TO OTHERS.
