Each MFSAB shall be equipped with a retractable lap
				belt assembly for the driver's seat. (See Section 12-807 of the Illinois
				Vehicle Equipment Law.) A shoulder harness is optional. Belt material, buckle,
				tongue, etc., of each driver's belt shall remain above floor when not in
				use.
Passenger safety belts that meet
				49
				CFR 571.222 are required on any MFSAB that
				has a GVWR of 10,000 pounds or less. Passenger safety belts are optional on any
				MFSAB that has a GVWR of more than 10,000 pounds. However, optional safety
				belts installed on any MFSAB are required to meet

The driver's seat shall be rigidly positioned and
				have a forward and backward adjustment without the use of tools or other
				nonattached devices.
Seat padding and covering shall be in good condition
				(i.e., free from holes and tears). Seat cushions shall be securely fastened to
				the seat frame.
Optional: MFSAB may be equipped with a durable
				safety belt webbing cutter with a full-width handgrip and a protected,
				replaceable, or non-corrodible blade. The webbing cutter cannot be mounted on
				the dash but must be mounted in a location accessible to the seated driver in
				an easily detachable manner.
REJECT VEHICLE IF:
Driver's seat is not securely anchored to floor; in
				poor condition; adjustment mechanism does not function properly. Optional
				webbing cutter does not meet requirements.

PROCEDURES/SPECIFICATIONS:
Each seat and each barrier are required to conform
				to FMVSS 222 (
				49
				CFR 571.222 ).

				fastened to part or parts of MFSAB that support them. No MFSAB shall be
				equipped with jump seats or portable seats (does not include child restraint
				systems). The center-to-center seat spacing shall be no more than 24 inches
				(60.96 cm), measured from the seating reference point to the seat back or guard
				barrier in front of the seat. Padding and covering shall be of fire resistant
				material. Minimum 36 inch (91.44 cm) headroom for sitting position above top of
				undepressed cushion line on all seats (measured vertically not more than seven
				inches from side wall at cushion height and at front and rear center of
				cushion). Backs of all seats of similar size shall be of the same width at top
				and the same height from floor and shall slant at the same angle with the
				floor. The top and side rails and seat backs shall be padded to cushion level.
				Seat padding and covering shall be in good condition (i.e., free from holes and
				tears). Seat cushions shall be securely fastened to the seat frame. (
				49
				CFR 571.222 )
Seat bottom cushions must also be equipped with a
				self-latching mechanism that is designed to flip up or be removable without
				tools.
REJECT VEHICLE IF:
Passenger seats do not meet requirements; are not
				firmly attached to body; seat frames are broken; cushions not firmly attached;
				padding and covering are not fire resistant. Padding or covering is loose, in
				poor condition, or missing; seats are torn or have holes; minimum seat
				dimensions or seat spacing is not in compliance.
d) STEERING SYSTEM
1) Exterior
A) King Pins
PROCEDURES/SPECIFICATIONS:
Raise vehicle so as to unload king pins (brakes
				should be applied to eliminate wheel bearing looseness). Either grasp wheel at
				top and bottom or use a bar for leverage. Attempt to rock wheel in and out.
				Check movement at extreme top or bottom of tire. If movement exists, place a
				dial indicator, tape measure, or a fixed device at the wheel and measure amount
				of movement.
Place leverage bar under tire. Raise bar to check
				for vertical movement between spindle and support axle.
REJECT VEHICLE IF:
Wheel bearing movement exceeds 1/4 inch or king pin
				movement exceeds:
Wheel Size
(in inches)
Max. Allowed
(in inches)
16 or less
1/4
16.1 to 18
3/8
over 18
1/2
B) Linkage
PROCEDURES/SPECIFICATIONS:
For MFSAB with single "I" beam or tube type front
				axle, hoist MFSAB under axle. For MFSAB with twin "I" beam type front axles or
				with "A frame" control arms, each axle or arm must be hoisted independently so
				as to load the ball joints. Grasp front and rear of tire and attempt to shake
				assembly right and left to determine linkage looseness. Measure movement of
				wheel.
Inspect for damage to or looseness in the following
				linkage components:
i) Ball Joints (Grasp wheel at top and bottom to
				attempt to rock wheel in and out. Check movement at extreme top or bottom of
				tire.)
ii) Cotter Pins
iii) Drag Link
iv) Idler Arm
v) Pitman Arm
vi) Steering Box
vii) Tie Rod
viii) Tie Rod Ends
REJECT VEHICLE IF:
Measurement is found to be in excess of:
Rim Diameter (in inches)
Max. Allowable Movement (in inches)
16 or less
1/4
17 and 18
3/8
over 18
1/2
Any linkage component is bent, welded, loose,
				insecurely mounted or missing.
C) Power Steering
PROCEDURES/SPECIFICATIONS:
Manually and visually inspect:
i) Belts
ii) Cylinders
iii) Fluid Level
iv) Hoses
v) Mounting Brackets
vi) Power Assist
vii) Pump
REJECT VEHICLE IF:
Steering components are:
i) Loose, frayed, cracked, missing; incorrect
				belts
ii) Loose and/or leaking
iii) Low fluid level
iv) Cracked, leaking, rubbed by moving parts
v) Cracked, loose or broken
vi) No assist is evident
vii) Loose, leaking
D) Toe-In/Toe-Out
PROCEDURES/SPECIFICATIONS:
With wheels held in a straight ahead position, drive
				vehicle slowly over the approved drive-on side slip indicator.
Excessive toe-in or toe-out is a general indication
				that a complete check should be made of all front wheel alignment factors
				(caster, camber, steering axis inclination).
REJECT VEHICLE IF:
More than 30 feet (914.4 cm) per mile on the
				approved side slip indicator.
E) Wheel Bearings
PROCEDURES/SPECIFICATIONS:
With the front end of the vehicle lifted so as to
				load any ball joints, grasp the front tire top and bottom, rock it in and out.
				Record movement. To verify that any looseness detected is in the wheel bearing,
				notice the relative movement between the brake drum or disc and the backing
				plate or splash shield.
AGENCY NOTE: Wheel bearing play can be eliminated by
				applying service brakes.
REJECT VEHICLE IF:
Relative movement between drum and backing plate,
				measured at tire, is 1/4 inch (.635 cm) or more.
2) Interior
A) Column
PROCEDURES/SPECIFICATIONS:
Inspect to determine that column support bracket is
				properly tightened and all bolts are present.
REJECT VEHICLE IF:
Column support bracket is not properly tightened or
				bolts are missing.
B) Lash
PROCEDURES/SPECIFICATIONS:
With road wheels in straight ahead position, turn
				steering wheel until a turning movement can be observed at the left road wheel.
				Slowly reverse steering wheel motion and measure lash.

				reinforcement ring is exposed.
E) Travel
PROCEDURES/SPECIFICATIONS:
