Hello, I am new to the forum but I have been an outsider looking in for years and usually can view threads to help with most problems on my machine but recently I've been stumped. Not familiar with hydraulics so any help is great.
I picked up a 1991 1845c that was in rough shape. Went over the motor, maintenanced entire machine. Installed a new hydrostatic and boom/curl hydraulic pump. When I started the machine it drove like new lots of power. The problem is the bucket curls fine but it only booms up when the auxiliary foot pedal is fully disengaged (opposite of when spring is closed). But when I do that the curl does not work. It will boom normally but extremely slow and will not stay up. I have checked all the linkages/cage is in right spot. Case dealer tech said replace relief valve. Sound right? The left boom piston was previously repaired (weld) and cause of high pressure (i think) sprung a pinhole leak. I've repaired the leak but still can only boom(lots of power) when I mess with foot pedal. Any help would be greatly appreciated.
