Bleed Hydraulics 257b3 Caterpillar

Just recently did work on my skid steer and lost a lot of hydraulic fluid. Can someone point me in the right direction to bleeding the lines? I filled reservoir with hydraulic fluid already.

Cat 257b3

You don’t need to. Operate the machine functions only at low idle RPM and slowly exercise each function back and forth but without taking the cylinders to the end of the stroke at the start. Keep stopping to check the oil level in the tank and top up as necessary. When the oil level stabilises indicating you have all the air out you can slowly move each cylinder to the end of the the stroke.

Awesome. Thanks again. Should this process take a bit? Did it for a few minutes and still felt the same

You will probably have to extend/retract each function about 20 times, taking the piston a little further on the stroke each time. Also don’t forget to slowly exercise the travel motors as well.

Works good now. Found another issue though….

The throttle is not working like it was before. The cable was removed when the motor was pulled so I’m assuming it’s just adjusting it correctly. What else could be the issue?
