9.7. Gear Re-alignment
There are two means of adjustment:

Spacers can be fitted or removed, thereby adjusting the height and wheel
loads.

The suspension / axle units can be moved slightly about the holes, thereby
adjusting the back-to-back.
9.8. Rail Wheel Checks
Rail Wheels which do not run true on the tread and flange will vibrate and give a
rough ride. If the vehicle vibrates and gives a rough ride on rail, there may be foreign
matter (dirt, rust, paint, etc.) between the wheel and hub, the spindle bearings may
be worn, or the tread and flange of the wheel may be worn or damaged causing a
wobbling sensation.
Track test the vehicle to verify whether the vibrations were caused by loose Rail
Wheels or flanges.
9.9. 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.
9.10. Wheel Bearing Checks
To check the wheel bearings, remove the metal cover to expose the castle nut and
split pin.
The bearings fitted are taper roller bearings. Ensure that the castle nut is not
tightened
– there should be 0.10mm end float. Usually it is sufficient to tighten the
nut, back it off ½ turn and then fit the split pin.
