Hello all I am new here and glad I found this Forum. I have been looking all over for a solution to my problem and have came up empty handed so I hoped someone here could help.
I have a 2002 Case 580 M Series I with 1700 hrs. I blew a low pressure line from the hydraulic filter to I believe the oil cooler. Spliced the line back together and replaced the lost oil ~5 gallons. Hooked my homemade gauge and bleeder to the pressure side quick connect to get the air out on the pressure side. Went to start the machine and had no pressure at idle. Gauge is reading about 100 psi at idle. When engine RPM's are increased to 2200 the gauge reads 200 psi. I put some air pressure on the main tank hoping that it was possible air locked with no different results. I looked at the owners manual and it mentioned a "Pump Replacement Procedure" but only said see dealer or service manual. I am hoping I have missed a step and the pump hasn't gone bad. It was working fine before the hose blew. The pump isn't and hasn't made any noise and I don't believed I starved it before It was shut off after the hose blew. Please help TIA
