Final Recommendation
1) O/H for Travel motor and Final Drive
may not be necessary in this time.
2) Swing motor hoses should be
replaced at proper interval.
Due to swing safety relieved oil with the relief pressure energy
is converted directly to oil temperature and around swing
motor becomes high temperature much different from tank.
