To reline the brake shoes and make a major ad-
justment, first remove the four universal joint at-
taching nuts and lower the propeller shaft. R emove
the retractin g spring clevis pin and the spring clip.
Remove the hug lock nut, the nut and washer from
the transfer case output shaft. Both the universal

Clean all parts with a suitable cleaning solution
and examine them for damage or wear.
Brake shoes may be disto r ted by improper lining
i nstallation and the lining shou ld be gro und true
after ins tallation on the shoes. For this reason it
is recommended that new or repl acemen t shoe and
lining assemblies be installed.
To reassembl e, first tum both adjusting screw
wheels away from the center to "all off" position.
Place a light film of grease on the brake actuating
cam and install the shoes. Inst all the black shoe re-
turn sp ring n ext to the cam and the ye llow spring

brake drum and universal joint flange in position
and install the transfer case output shaft washer,
nut and hu g lock nut.
Rotate the drum until one pair of holes in the drum
are oppos i te the two adjusting screw wheels in the

Ex amine the brake operating cable to be sure that
it is not worn or damaged. Fr ee it up thoroughly
and lubricate it. Make sur e the operat ing handle

slack in the cab l e. Tighten the clevis lock nut.
After the cab le is conne cted back off seven n otches
on each adjusting screw wheel which will give the
proper runn ing cl earance bet w een the lining and
the drum.

sp ring clip, clevis pin and th e cotter pin, also, in-
stall the retracting spring link and spri ng.
The position of the brake operating lever, Fig.
289, must be correct ly set. Th e position of t his
l ev er (see arrow in Fig. 289), is determined by the
a djustment of t he cam or br ake ope r ating l ink,
which spreads the two shoes. Th e opera ting link is
a djus te d by means of the special ball nut to set the
operating l ever with ~" [2.38 mm.] clearance
between the closest point of the lever and the brake
bac king plate.
The pos ition of this lever should be checked when
making a major adjustment or when relining the
