and into spindle.
Loosen self-locking nuts on eccentric
spindle screw, using socket wrench (2)
(item 83, appx B). Nuts are torqued to
600 ± 25 ft-lb (810 ± 34 N-m) (oiled
threads and washer). Drive wedge (item
72, appx B) into joint to relieve tension
on eccentric spindle.
4 Move vehicle slowly rearward, rotating
bar and eccentric spindle 1/4 to 1/2 turn,
and decrease track tension.
5 Remove wedge from spindle. Tighten ec-
centric spindle screws and nuts as tight
as possible using socket wrench. As
soon as possible have unit maintenance
personnel check and torque spindle nuts
to 600 ± 25 ft-lb (810 ± 34 N-m) (oil-
