Hydraulic pressure for boom.

[David w]

I have a international 1999 4700 Dt466E Couldn't get the bone to move so I adjusted on a Couple of the adjustment screws only hydraulic system.
And now I got it to work. It keeps blowing out hydraulic lines. Any advice? Please help? I think I turned the hydraulic pump up too much.

Most likely you set the pressure relief too high, or the hoses are junk. Need to tie a gauge in to see what the relief is set at. If you're not comfortable working on high pressure hydraulics it's best to let someone how is do it.
