Hendrickson RS Series
1. Inspect the frame hangar to frame attaching fas-
teners for the proper torque. See Group 00 of
this manual for torque specifications.
WARNING
Be sure that fasteners are torqued correctly. Fas-
teners that do not provide a tightly clamped joint
between the frame and the hanger can cause pre-
mature fracture of the frame hanger, separation of
components, loss of vehicle control, and possible
personal injury or property damage.
2. Inspect each frame hangar for any evidence of
cracks in the vertical mounting flange. See
Fig. 8.
3. Inspect each frame hangar for evidence of
cracks in the horizontal mounting flange adjacent
to the vertical drive pin area. See Fig. 9.
4. Inspect each frame hangar for severe rust on the
horizontal mounting flange adjacent to the verti-
cal drive pin area. See Fig. 10.
5. Inspect the load cushions for cuts and swelling.
Cushions cut by the retaining lips of the saddles
or frame hangars indicate the cushions may not
be the correct hardness or configuration for the
vehicle operation.
6. Inspect the lower side of the vertical drive bush-
ings for evidence of torn or shredded rubber.
Check that the concave washers are installed
with the lips pointing downward.
7. Inspect the saddles and saddle cap fasteners for
wear. The allowable thrust washer wear in alumi-
num saddles is up to 3/16 inch (4.8 mm) into the
saddles as measured at the top of the thrust
washer diameter. Check that the locknuts are
torqued to specification to prevent wear of the
beam center bushings into the legs of the
saddles. See Group 00 of this manual for torque
specifications.
