Note
The truck must be parked on smooth level ground when checking and
adjusting the mast bearing wear pads.
Mast Bearings
The bearings on the mast do not require periodic greasing. Check the mast bearings
for cracks or flat areas on the surface and also check for restrictions to rolling.
Replace if any of these are detected and try to eliminate the cause(s) of the failure.
Principle Causes of Bearing Failure
Shocks
Violent frontal collisions during loading can cause bearings to
fail.
The external surface will show cracks that cut the surface
parallel to the rolling axis.
Large Load Centre
Another possible cause of breakage is the mounting of special
equipment to handle loads with a very large load centre e.g.
carpets, even if their weight is lower than the rated capacity.
This condition creates oscillations that cause the detachment of the external
hardened surface of the bearing. In this case circumferential cracks will appear and
will run completely around the roller.
Mast Bearing Wear Pads (If applicable)
If the mast bearings are the type with integrated wear pads the wear pads must be
checked every 500 hours and adjusted if necessary. Raise and lower the mast fully.
Be on the lookout for kicking or sticking.
To adjust the mast bearing wear pads:
1. Turn the locking nut (
A
) anticlockwise a
couple of turns to loosen.
2. Turn the adjusting screw (
B
) clockwise
until the wear pad comes into contact
with the adjacent mast channel.
3. Repeat steps 1 and 2 on the bearing
directly opposite.
4. Turn the adjusting screw ¼ turn
anticlockwise then tighten the locking
nut.
5. Repeat step 4 on the bearing directly opposite.
6. Repeat steps 1-5 until the wear pads have been adjusted on all mast bearings
