MAINTENANCE PROCEDURE RUBBER SHOE CORE SEPARATIONS If the rubber core has separated at one place or more, replace with a new part. RUBBER SHOE TENSION 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 If the cracks between the rubber shoe lugs increase to a size of approx. 60 mm (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 30 mm (1.18 in.) or the depth of the crack is less than 10 mm (0.39 in.), there is no particular need to carry out repairs. When making judgement whether to replace, repair, or contin- ue using rubber shoe and load liner, please contact your Ko- matsu Dealer. 186
