On Track Fault Finding
Problem
Probable Cause
Possible Remedy
Vehicle pulls
noticeably to the
left or right when
on track.
Vehicle loaded heavy on one
side.
Rail Wheels not aligned with
vehicle.
Vehicle road tyres under
inflated.
Front road wheel toe-in out
Move load to centre of vehicle.
Re-align.
Check pressure. Inflate to correct
pressure if low. Do not exceed tyre
manufacturer’s recommended
maximum pressure.
Adjust.
Vibration felt in
the vehicle when
traveling on track.
Rail Wheel out of alignment.
Mounting hardware loose.
Rail Wheel bearings loose.
Vehicle rim bent.
Re-align on test track.
Tighten all bolts to the recommended.
Tighten/replace bearings.
Replace wheel. Check tyre condition.
18.15.
Trailer Air Brake System
The air pressure must be checked on both connections (front and rear), according to
the frequency outlined in the maintenance schedule.
Do not connect a pressure gauge directly to these connections, as any attempt to
set the correct pressure will be unreliable
– use a long hose between the gauge and
connectors to simulate the trailers.
To release the air pressure in the system to test the low-pressure buzzer alarm
insert a
“C type male coupling” into one of the single line brake couplings. Chock the
vehicle wheels. Release the handbrake until the air has dropped below 5 bar, then
apply it. Alternatively bleed air from the system using the test point connected to the
air reservoir. The buzzer should sound and cut out once the air pressure has re-
pressurised above 5 bar.
At the beginning of every shift the air tank should be drained of moisture/water via
the test point at the bottom of the tank. This can be done using a test point adapter.
Only minimal water should be present. This will help preserve / extend the life of the
air reservoir.
