14. Complete passenger and driver’s side installation of air spring assembly.
15. Cut air brake lines to length and connect air lines to fittings by pushing the air line into
the air fittings as far as possible.
WHEN CUTTING AIR BRAKE TUBING, A SQUARE
CUT IS REQUIRED AND THE HOSE END MUST NOT BE DEFORMED OR LEAK-
AGE MAY RESULT. IF DEFORMATION OF THE HOSE END OCCURS, THE
HOSE END MUST BE REWORKED SO THAT IT IS ROUND. Engagement of the
sealing O-ring will be felt when the air line has been inserted properly into the fitting. Fittings
may be disconnected if required by pushing down on the outer ring while pulling firmly on
the air line.
Route air lines away from exhaust pipes or any other sources of heat and ensure
that the air lines are protected from sharp edges.
16. Route air lines as shown along the emergency brake cables. Lines MUST be
routed as shown with shielding and tie straps installed on air lines as shown. Fail-
ure to install air lines as shown will result in excessive flexing of air lines and po-
tential leaks. Air lines can be routed as required after being tie strapped to the
emergency brake cable frame bracket.
