3.6 DRAG LINK
Drag link assembly consists of three parts; a
drag link and two end assemblies. Both end
assemblies are identical and they are retained
on the drag link with a clamp bolt and nut.
Stud nuts at the pitman arm and bell crank ends
of the drag link must be kept tight or hole at ball
stud end of drag link and hole in pitman arm
may become enlarged as a result of excessive
looseness. Subsequent tightening of stud nuts
may draw studs too far into holes and dust cover
parts may become damaged which can result in
component failure.
Drag link end sockets are equipped with
lubrication fittings and should be lubricated as
directed in "Lubrication Fittings" in this section.
3.6.1 Adjustment
It should not be necessary to alter the length of
the drag link except when a new link is installed
or when removable end assembly has been
replaced. If drag link adjustment is necessary,
proceed as follows:
1. Position front wheels in straight ahead
position.
2. Center steering gear as previously
explained in paragraph "3.3 Steering
Linkage Adjustment".
3. Remove cotter pin and stud from drag link at
bell crank. Locate centerline of vehicle and
center of relay rod. With center of relay rod
aligned with centerline of vehicle, loosen
clamp bolt at socket end (bell crank end) of
drag link and adjust length of socket end
assembly to fit in boss of bell crank.
NOTE
Do not change position of pitman arm.
4. Install stud nut and torque to 160 lbf-ft (220
Nm). Align nut with cotter pin slot (tighten)
and install a new cotter pin.
5. Torque mounting clamp bolt nut to 40-60 lbf-
ft (55-80 Nm), then test the adjustment.
Front wheels should turn from right to left
extremities without noticeable binding at
drag link ends.
3.7 BELL CRANK AND IDLER ARM
Bell crank and idler arm are equipped with one
lubrication fitting and should be lubricated as
directed in paragraph "3.11 Lubrication Fittings"
of this Section.
