TM 5-3895-371-24 & P
Installation of Bitumeter Wheel Solenoid Valve and Air Chamber. (Refer to fig. 2-25.)
Mount air chamber (1) on bracket (11). Long threaded shaft should pass through
center hole of bracket.
Install two nuts (6) and washers that fasten air chamber (1) to mounting bracket (11).
Install yoke locknut (8) and air chamber yoke (9). Screw the yoke on to the air cham-
ber (1) until hole in yoke lines up with hole in wheel fork; then tighten yoke locknut (8).
Install capscrew (10) and nut that fasten the air chamber yoke (9) to the wheel fork.
Connect spring (7) to air chamber (1).
Screw solenoid valve (5) into top of air chamber (1).
Connect air supply line (2) to solenoid valve (5).
Connect solenoid ground wire (4) to bracket and secure with capscrew, washer, and nut.
Connect solenoid power line to quick-disconnect (3).
Close petcock and open main air valve. (Refer to fig. 2-24.)
Servicing of Oiler Lubricator.
Close gate valve (main air valve, fig. 2-24) then exhaust air supply from bituminous tank
by opening air control reservoir drain petcock.
Remove glass cup from oiler lubricator.
Add OE 10 oil to cup and replace cup.
Close petcock on air supply tank and open main air valve.
Start engine to replenish air supply.
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.
