I've got an interesting leak i replaced the hose from the pump to valve block no leaks and ran fine. After bout hour noticed oil smell and found the breather for the gearbox purging oil from the ports and also the main input shaft seal was blown out. Not sure if anyone had ever encountered this, appears as tho the pump shaft seal has failed and the gearbox seal failed and thus put pressure in the gearbox which took out the seal. Still have hydraulic pressure to run cylinders but now fluid level to low to operate. Any help would be greatly appreciated.
