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
etc….
18.9. Conductivity test
The Kubota should also be tested to the following specification.
1. The conductivity between the wheels on each axle needs to be checked using
a calibrated resistance meter.
2. Zero the meter so the display reads 0.00
Ω.
3. Connect one lead to each of the wheels on the same axle. The measured
resistance should be less than 0.15
Ω.
4. Repeat on the other axle.
18.10. Rail Wheel Inspection for Wear
The rail wheels have a P1 profile. Use the appropriate Go / No-go gauge to check for
wear.
18.11. 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.
18.12. Engine and Gearbox Access
The rear load / seat tub can be lifted up to gain access the engine, gearbox, lifting
points and other serviceable items. Remove the index pins from either side of the
tub. Lift the tub up using the handles sited underneath on either side. The mass is
compensated using gas struts. Lowering is a reverse of these operations. The tub
should only be lifted when there is no load or passengers on it. The gas struts are
non-serviceable items and should be replaced if damaged or faulty.
