Introduction
Planned maintenance
oo.
Foreword
The maintenance operations consist of checking and restoring the efficiency of certain vehicle compo­
nents subject to wear which may deteriorate during normal usage conditions.
This section describes the operations which should be carriedout on the vehicle at the intervals set out in
the Planned Maintenance Programme (on the previous page). Each operation is described indepen­
dently on account of which there is no pre-defined ideal operating cycle to be repeated at each interval.
It is therefore necessary to ensure that those operations which require the same components to be dis­
mantled are carried out at the same intervals in order to maximize the efficiency of the repair times.
If, when carrying out each operation, the need arises to carry out additional replacements or further re­
pairs not envisaged in the Planned Maintenance Programme, prior approval must be obtained first from
the Customer.
PLANNED MAINTENANCE OPERATIONS
H CHECK CONDITION OF TYRES AND
WEAR
Check the condition of the tyres making sure,
in particular, that there are no signs of ageing
on the tread and the tyre walls, that the tyres
are not excessively/unevenly worn and that
there are no abrasions/burrs, porousness or
cuts.
Check the depth of the tread using a special
gauge, taking the measurement at the inter­
section between the transverse and longitu­
dinal splining (at several points on the cir­
cumference). The minimum permissible
depth is 1.6mm. The difference between the
depths of tread on the same tyre should not
exceed 2 mm. The difference between the
depths of tread on different tyres on the same
axle should not exceed 5 mm.
If the tread wear is uneven, check the tyre in­
flation pressure and inform the Customer of
the possible need to balance the wheels.
