What to look for in a cat 315B excavator?
What to look for in a cat 315B excavator?
If this orifice is blocked, the brake can stick. The engine would lug and pump would be noisy trying to over come the brake or blockage. If the pump is not building pressure and the engine is not lugging down under a load ( even slightly) then I would look for a problem in the pilot pressure to the control valve.
What was the name of the cat excavator?
We have got a CAT 315b Excavator that was traveling extremely slow so they replaced some seals. Not sure exactly the name of that part right off but now one side travels great and the other will do nothing. Submitted: 10 years ago.
How to troubleshoot a cat hydraulic excavator with low power?
When it comes to troubleshooting low power concerns on a Cat® Hydraulic Excavator, Caterpillar Maintenance Expert Jeff Payne says look at the simple things first, such as checking your machine air filters and fuel filters for restrictions – before looking at cycle times; swing, stick, bucket and boom times, or valve adjustments.
How does a low pressure excavator work?
It is a low pressure system that move the spools in the control valve but, it is mostly separated from the main pressures. If pressure will build in the system, all controls are working. The pressure will flow when you switch lines so, the blockage must be in the other lines.

How does pilot pressure work on an excavator?
Pilot pressure is the pressure used to work the controls from the foot pedals and the joysticks. It is a low pressure system that move the spools in the control valve but, it is mostly separated from the main pressures. If pressure will build in the system, all controls are working.
Can a PRV problem affect a cat excavator?
A PRV problem would affect every function. Every Cat excavator I’ve seen requires pressure to move the travel motors to low displacement/rabbit mode. The smallest line running through the swivel will be the one to the travel motor speed actuators. You could try to plug it and see if anything changes.
Why are the tracks on my Cat 320n not turning?
The smallest line running through the swivel will be the one to the travel motor speed actuators. You could try to plug it and see if anything changes. If the battery voltage dropped low enough, the solenoid valve for the two speed might drop out. Maybe it’s an electrical problem…..
