18.16. Trailer Hydraulic Brake System
Some vehicles have been fitted with a hydraulic braking system to accommodate the
trailer brakes. The pressure must be set to that shown in the Technical Specification.
The oil tank, mounted on the pump, is located under the front bonnet, as shown
below. Ensure that oil to the correct specification only is used.
The hydraulic 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.
18.17. Gear Re-alignment
There are two means of adjustment:
•
Spacers can be fitted or removed, thereby adjusting the height and wheel
loads. Fine adjustment bolts are fitted either side of the rail gear acting as
stops. This will aid achieving wheel loadings.
•
The suspension / axle units can be moved slightly about the holes, thereby
adjusting the back-to-back.
18.18. Suspension Checks
Do not leave heavy loads in the rear load bay whilst on track for prolonged periods.
If the suspension units ‘squeak’, then dirt has become trapped inside the nylon
bushes and the shaft. Clean out the units with clean brake fluid from both ends.
No further maintenance is required as they are sealed for life.
18.19. Life Guard Checks
The rubber life guards should be renewed if damaged, worn or age hardened. The
gap from the rail head should be approximately 25mm to allow for suspension travel
(the maximum gap permitted is 30mm).
