MAINTENANCE MAINTENANCE PROCEDURE Rubber Shoe Steel Code Cuts 0. If more than half of the steel cord layer on one side is cut, replace with a new part. Rubber Shoe Core Separations 0. If the rubber core has separated at one place or more, replace with a new part. Rubber Shoe Tension 0. If the rubber shoe is still slack even when grease is pumped in, replace with a new part or replace the seal inside the cylinder. If the track tension can only be increased to a level where the rubber shoe may come off, there may be not only elongation of the rubber shoe but also damage to the grease cylinder. Rubber Shoe Cracks 0. If the cracks between the rubber shoe lugs increase to a size of approx.
60mm (2.36 in) the rubber shoe must be repaired. Even if the crack is small and short, if the steel cord can be seen inside, carry out repairs immediately. If the length is less than 30mm (1.18 in) or the depth of the crack is less than 10mm (0.39 in), there is no particular need to carry out repairs. When making a judgement whether to replace, repair, or continue using the road liner and rubber shoe, please contact your Komatsu distributor. 4-29
