well my smallest excavator has been foaming in the hydraulic tanks for the last few days, let it sit 30 minutes or so and the foam would disappear and machine would function fine. Weirdest part was it was an intermittent problem, well today after running for about 30 minutes there was a loud pop and the joysticks jumpped. Now no hydraulic functions at all, bobcat is comming in the morning to pick up, I was able to drag it out of the spot it was in and out to the road with a second machine but was unable to get it loaded on my trailer. Am I over thinking this or am I probably due for a hydraulic pump?
