METHOD FOR CHECKING RUBBER SHOES
If the rubber shoe is in the following condition, it must be repaired or replaced. Ask your Komatsu distributor for
repair or replacement.
Lug height
• When lug height (a) is reduced to 5 mm and below
{0.197 in and below} , replace it with a new one.
If lug height (a) is reduced by wear, the drawbar pull will
drop.
(1) Track roller
(2) Rubber shoe
• If the lugs are worn and the steel cords in the shoes are
exposed on continuous 2 or more links, replace the track
with a new one.
Cut of rubber shoe steel cords
If more than a half of the steel cord layer is cut on either side,
replace the track with a new one.
Separation of rubber shoe core metal
If the rubber shoe core metals are separated at 1 or more pla-
ces, replace the track with a new one.
Rubber shoes track tension
If the rubber shoe track tension is still low after grease is sup-
plied, replace the track with a new one or replace the seals in
the cylinder.
If the rubber shoe track cannot be tensed to a degree that it
does not come off, not only the track is lengthened but also the
grease cylinder may have trouble.
