CAT 308C Boom and Bucket not working

[James R.]

I'm having a problem with my CAT 308C. The cab still rotates and the tracks work normally, but the boom and bucket have no hydraulic function. Has anyone experienced this issue or know what could be causing it?

I'd check the hydraulic pump, pilot pressure, and control valve first since the travel and swing still work.

That’s interesting. If the travel and swing are still working, could a pilot pressure or control valve issue be affecting just the boom and bucket circuits? Has anyone traced a similar problem back to a blocked line or faulty solenoid on a 308C?
