Step 16
Inner tube assembly Inspection
Do not replace the inner tube assembly unless the diameter
of the trailer is 0.650 inch (16.5 mm) or less, as described
in Step 15(d). If replacement is not required, use water and
an abrasive-type household cleanser applied with a bottle
brush to remove any surface carbon deposits from the liner
of the inner tube assembly. Thoroughly rinse and dry the
assembly immediately after cleaning. See Figure 20.
Minor scratches on the inner tube assembly are allow-
able. Tubes with rough scratches must be replaced because
the rough scratches may impede proper operation of the
Loadbuster Loadbreak Tool. DO NOT repaint the tube.
Step 17
Inner tube seal Inspection
Examine the inner tube seal. Replace the seal if it is cracked,
deformed, or damaged in any way. S&C recommends
replacing the inner tube seal when the inner tube assembly
is replaced. See Figure 21.
Step 18
Stationary contact assembly inspection
Use water and an abrasive-type household cleanser to
remove any surface carbon deposits from the stationary
contact assembly. Thoroughly rinse and dry the assembly
immediately after cleaning. Examine the stationary contact
assembly for extreme pitting, erosion, or cracking. Light
polishing is permissible, but avoid heavy filing that would
change the dimensions. Replace the stationary contact if
the ring inside the contact is bent. Be careful not to drop
the contact assembly. See Figure 22.
