MAINTENANCE PROCEDURE
186
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.
