Despite the strict quality control of CCM at the Caterpillar PL87 Pipelayer it turned out that on some models the metal tracks where incorrectly fitted.
In good consultation with CCM, Ad Gevers made this Caterpillar PL87 Pipelayer Track Repair Instruction using a photo reportage with instructions to show you that it is possible, to safely and without damage to the model, to undo this mistake.
Of course you can also apply this basic instruction if you want to perform a repair on the tracks on another scale model
