Cat 328D Work tool malfunction

[George catman]

Morning,

We have a Zero tailswing 328D (Serial prefix - RMX) excavator with a fault coming up on the monitor panel stating "work tool malfunction" :Banghead the tilting mud bucket will only tilt in on direction correctly with full operation and wont quite tilt back the other way, we have ET and are going to head out of town 4 or 5 hours drive to check it out was wondering if any one has come across this type of fault before and had any suggestions of parts we may want to take with us when heading out that may save a reasonable amount of travel to and fro?????? Any suggestions would be great?

Thanks

A Diagnostic Code will nail it down. Long drive to get one though............other than that I can't help you.

variable line relief valve, have one on each line and it sounds as one of them isn't working, then they bypass oil to tank.
