Mount the tee (part no. TA37004) as shown below.
NOTE: The dimension of 250mm is a legal requirement for NZ fitment and it is
recommended this standard is used in other countries where CTI systems are
not legislated. Do not fit this tee until the guards are fitted on the drive tyres.
a. Relocation of the hose support hangers towards the horizontal centreline
position of the axles. The maximum vertical height difference between
the centre of the rotating union and the height of the centre support
is to be no more than 250mm. Leave a slight loop in the hose to allow
for independent axle movement. The hose length is not to exceed the
distance measured between the fixed point where the hose is attached to
the truck (usually a tee) and the centre of the rotating union plus 20%.
b. Hose support hangers may require custom modification for various
suspension
types.
c. Ensure that hose hangers are reinforced adequately to prevent cracks
from
vibration.
d. Hangers and hardware, including shut off valves must remain within the
overall vehicle width of 2.5 metres (Note: Hardware excludes flexible air
hoses and protection).
e. The supply hose that extends to the outside edge of the hanger must
have adequate protection from road debris coming from the tyres. (This
protection may be by fenders over tyres, or guards over the supply hose).
