ber (1) until hole in yoke lines up with hole in wheel fork; then tighten yoke locknut (8).
(4)
Install capscrew (10) and nut that fasten the air chamber yoke (9) to the wheel fork.
(5)
Connect spring (7) to air chamber (1).
(6) Screw solenoid valve (5) into top of air chamber (1).
(7)
Connect air supply line (2) to solenoid valve (5).

NOTE
The safety valve located just below the main air valve
at the main air tank will allow air to pass through the
bituminous air tank only after the pressure is above 65
Ibs. This provides a safety factor so the truck will not
be starved of air pressure for the service brakes.
