I have a CAT 345C Excavator (S/N PJW02374) with some violent vibration issues when the hydraulics are engaged.
Machine recently blew a large hydraulic hose while on a steep slope and managed to dump all, or atleast 50+ gallons of hydraulic oil.
Other technician replaced the hose but did not re-fill the hydraulics before the operator decided to jump in and run the machine.
Hydraulics were slow and machine began to violent shake. The technician proceeded to add only 10 gallons of oil before he decided to track the machine down the hill and park it. Since then, the hydraulics have been completely re-filled, air was bled as best they could from the lines and they are still having violent shaking issues and very slow hydraulic movement from the Stick, Boom, Bucket, and Tracks. Swing is fine.
New hydraulic filters all around, new oil, and the main relief valve was cleaned by the other mechanic.
Any ideas of what it could be, before I tackle this machine later this week?
