i bought a trojan 1900 wheel loader when i got it the bucket cylinder was leaking oil so i took it to this hydraulic shop and they ended up making a new tube & rod when i installed the cylinder i notice the control valve was missing a piece that the dealer doesnt make any more so i bought a used valve from the dealer and when i installed it now the cylinder is bypassing(when i lift it up it does down by itself) what can be the cause the cylinder or the valve?
