l5030 won't go forward after removal of HST servo

[cboydfarms]

I have a l5030 that was disassembled to install new mfwd shaft seal, the directional servo was removed to install another leaking seal, when reassemble unit would not go forward, reverse works as it should, when testing forward and reverse pressure the forward has none and the reverse is within spec, removed servo and check alignment of servo actuating arm, resealed the servo piston, any help would be appreciated
