Multiple Ride Height Adjustment
The RTN trailer gooseneck can be adjusted to
provide a standard ride height with a range of tractor
fifth wheel heights or multiple ride heights with any
given fifth wheel height. This adjustment is accom-
plished by positioning the compression blocks to mesh
with the gooseneck link through a range of positions.
An adjustable stop cam is provided to stop the com-
pression blocks in a preselected position. See figure 9.
NOTE: The top tooth of the compression block must
always be above the top tooth of the gooseneck link
when the block and link are engaged in the travel posi-
tion. Likewise, the bottom tooth of the compression
block must always be below the bottom tooth of the
gooseneck link (see figure 9).
WARNING
All teeth on the gooseneck link must be fully
engaged with the compression block when in
the Travel position.
