For Hendrickson RT2 and RTE2 Series, lubricate the
bronze, ball-indented bushings in the spring eye, as
follows:
1.
Park the vehicle on a level surface, apply the
parking brakes, and chock the front tires.
2.
Raise the rear of the vehicle until the rear wheels
are suspended in the air, then support the ve-
hicle with safety stands. This relieves the load on
the bushings and pins to allow the proper flow of
lubricant around them.
3.
Use a multipurpose chassis grease and lubricate
the bronze, ball-indented bushings in the spring
eyes at the grease fitting; see
. Continue to
lubricate until grease exits both ends of the
bushing. If the pin will not accept lubricant, re-
move the pin and clean the lubrication channels
where lubricant may have hardened. Lower the
vehicle and remove the safety stands.
32–03 Suspension U-Bolt
Torque Check
NOTICE
Failure to retorque the U-bolt nuts could result in
spring breakage and abnormal tire wear.
1.
Park the vehicle on a flat surface, apply the park-
ing brakes, and chock the tires.
2.
Check the U-bolt torque in a diagonal pattern.
Set a click-type torque wrench to the highest
torque value for the fastener being checked. See
for U-bolt torque specifications. Turn the
wrench in a clockwise motion (looking up) until
the torque wrench clicks.
