Check Undercarriage Oil - Komatsu D475A-5E0 Operation & Maintenance Manual

MAINTENANCE

CHECK UNDERCARRIAGE OIL

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. Ask your Komatsu distributor for repairs.
REMARK
Bogie shaft seal bolt (1) is located on both the inside and outside.
