Lug height
• When lug height (a) is reduced to 5 mm or less, replace
the road liner with a new one.
If lug height (a) is reduced by wear, the drawbar pull will
drop.
For judgment of replacement, repair, and continuation of use of the road liner, consult your Komatsu distributor.
METHOD FOR REPLACING ROAD LINER
(Road liner specification)
• When all the road liners of the machine need to be replaced, ask your Komatsu distributor to replace them.
• When replacing only part of the road liner, use the special road liner removal tool. Order the tool from your
Komatsu distributor.
METHOD FOR REPLACING BUCKET TEETH (VERTICAL PIN TYPE)
Replace the bucket teeth before the adapter starts to wear.
• It is dangerous if the work equipment moves by mistake when the tooth is being replaced.
Set the work equipment in a stable condition, set the lock lever securely to LOCK position, and stop
the engine.
• As the pin is driven out with strong force, it is dangerous that the pin may fly out. Check that there
is no people in the area around the machine.
• Broken pieces may fly during the replacement work, so always wear the protective equipment such
as protective eyeglasses and gloves.
