remove bellows.
Replacement is the reverse of removal.
Bellows should be examined for punctures,
deterioration, cracks and chafing. Bead rings should
be examined for deformation or sharp edges. If in
satisfactory condition, bead rings can be used with
new bellows. After installation, check carefully for
leakage at bellows bead rings. This can be done by
coating the area around the bead ring with soap and
water and checking for any sign of bubbles. Tighten
bead ring nuts in sequence to avoid distortion of the
bead ring.
RADIUS RODS
The following instructions apply to radius rods
used at the front and rear driving axles.
Radius rods are mounted at both ends by means of
rubber bushings. The condition of these bushings
should be checked periodically and any defective
parts replaced. Radius rods should be checked f~r
distortion and cracks. The "Magnatlux" process 1s
recommended for detecting cracks in the radius rods.
New rubber bushings should be used when rods are
replaced.
CAUTION: No lubricant whatsoever is to be used
at the rubber bushings.
REMOVAL AND REPLACEMENT
To remove radius rods, flatten attaching nut
locking plate and remove nuts. Remove radius rod
ends from anchor pins, and withdraw radius rod.
For reassembly, it is recommended that the radius
rod bushing installing tool shown in Figure 12-6. be
used. A suitable tool can be made locally accordmg
to the dimensions shown.
Installation of the radius rods is the reverse of
removal. It is extremely important upon reconnection
of the rods that the proper clearance height between
the axle and body is maintained, otherwise the rubber
bushings in radius rod ends will become preloaded,
shortening the life of these parts. Refer to Figure 12-
4 & 12-5.
