Maintenance
Mounting Hardware
The tank is attached to the truck frame with spring
loaded bolts. Wooden blocks are mounted between the
tank and the truck frame to absorb shock loads and to
act as wear surfaces. During use, the blocks wear and
mounting hardware will need to be tightened. To tighten,
follow this procedure:
1. Stop the engine, place all controls in neutral, set
the park brake and remove ignition key. Be sure the
tank is cool to the touch.
2. The best time to check the hardware is at the start
of the working day.
3. Tighten the anchor bolts. Measure spring length
and maintain at 2.75 inches (7 cm). The spring coils
should have a visible gap between them.
4. If mounting bolts can no longer be adjusted to
proper spring compression, the wooden blocks
must be replaced.
5.
Keep the hardware tight at all times to prevent the
tank from shifting on the frame.
Capacity Indicator Gauge
A pointer gauge is located on the front and on the rear
of the tank to indicate the amount of asphalt in the tank.
The float in the tank is attached to a shaft through the
tank wall and moves the pointer accordingly. The shaft
is sealed with packing material to prevent leakage. If
the seal needs adjustment or replacement, follow this
procedure:
1. Stop the engine, place all controls in neutral, set the
park brake and remove ignition key.
2.
Check under the float shaft at the start of each day
for seal leakage. If seal is leaking, tighten the nut
on the packing gland 1/3 turn at a time. Fill the tank
and determine if the float shaft still leaks. Repeat
if leaking continues. If the nut bottoms out and the
shaft still leaks, replace the seal.
Do not over-tighten the packing gland
nut. If it is too tight it will bind the shaft, preventing
the shaft from turning properly.
3. Before replacing seal, empty the tank and allow it to
cool. Remove the pointer from the shaft. Loosen and
remove the packing nut. Use a small screwdriver to
remove the old packing material from the cavity.
4. Install the new packing into the cavity. Install the
packing nut and turn until it contacts the packing
material. Use vise grips to turn the shaft and lift the
float. When the shaft is released, the float should
turn the shaft easily as it moves down. Install the
pointer in its previous position.
