Why is my cat 320C excavator engine stalling?
I have been having a lot of trouble with a CAT 320C Excavator (S/N BDE00683) with 16 000 hours on the clock, which my boss just bought. The excavator is well serviced, engine looks and works well, but when under load, the engine revs go down very fast, it stalls and there is no hydraulic power. I can excavate only with the tip of the bucket.
How much hydraulic power does a cat 320C have?
I followed the instructions from CAT and I should have measured 0,2 to 0,75 Amperes at the Solenoid input and 4,8bar (70 psi) to 34,5 bar (500 psi) pressure at the tap. However, for the electricity I get 0,14 to 0,5 Amps and for the pressure I get 4bar (58 psi) to 22 bar (319 psi).
