Check Undercarriage Oil - Komatsu D155A-6 Operation & Maintenance Manual

MAINTENANCE

CHECK UNDERCARRIAGE OIL

Stop the machine on level ground, and check for any reduction in
the oil in the idler (portion P), track roller (portion Q), bogie shaft
(portion S), 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.
REMARK
If the side cover is not removed, seal bolt (1) at the idler portion
cannot be seen.
There is 1 bogey shaft seal bolt (1) each on the inside and
outside.
