FRAME ALIGNMENT INSPECTION (Contd)

HORIZONTAL BOW INSPECTION (Contd)

NOTE

Strings used for horizontal bow measurement will remain in

place until the frame squareness procedure is completed. On

frames longer than 20 ft (6 m), the two front and rear strings

will be used.

Stretch string tightly on floor (5) between front and rear plumb bob marks (2) under each frame

rail (1). Place weights on string to keep it taut or tie ends of string to jack stands.

NOTE

For frame rail sections with added fishplate, subtract 5/16 in.

(7.94 mm) from plumb bob marks to compensate for the

fishplate added to frame rail.

If measured frame rails are out of tolerance, notify supervisor.

If frame rails are verified to be out of tolerance, vehicle will be

classified as unserviceable.

Measure distance between string and each plumb bob mark (2). If distance is more than

1/2 in. (13 mm) from bow (3), or 1/2 in. (13 mm) from bow (4), frame rails (1) are out of tolerance.
