2.7 Wearing Plates
Wearing plates are welded to the pontoon at the portions where the pontoon contacts and
frictional with the track rollers or track pins during travelling and steering. Without these
wearing plates, the said portions at the pontoon are very fast and very easy to get wear.
Therefore, be sure to make the following checks in order to keep your pontoons are applicable
for long term use:
2.7.1 The rate of wear and tear for the wearing plates should be checked at the bottom and
the upper corner of the pontoons which are subjected to most severe wearing rate.
Figure 2.11
2.7.2 Inspect & measure the thickness of the wearing plates for every 100 hours and make
replacement if the remaining thickness of the plate is below 4mm.
WARNING! Failure to replace the wear wearing plates could cause serious damage to pontoon
body. Moving track chain is just like a blunt saw waiting to cut off the pontoon body after the
wearing plate have been finished ‘cut-off’.
