MAINTENANCE
SERVICE PROCEDURE
CHECK UNDERCARRIAGE OIL
WARNING
If the oil level in the idler is low, new oil must be added, and the machine body must be inclined in this case. Since this work is
dangerous, ask your Komatsu distributor.
REMARK
At the idler portion, seal bolt (1) cannot be seen if the side outer cover is not removed.
Stop the machine on level ground, and check for any reduction in
the oil at the idler (portion P), track roller (portion Q), and carrier
roller (portion R).
1.
Loosen seal bolt (1) slowly and check if oil oozes out from the
thread. If oil oozes out, the oil level has not gone down, so
tighten the bolt.
2.
If no oil comes out even when seal bolt is removed, the oil level
is low. Contact your Komatsu distributor for repairs.
