Hydraulic Valve Front Seal YM142 Start engine and check forYanmar Tractor Hydraulic Valve Front Seal This seal is really more of a wiper than a seal. It is designed to keep dirt and grime out of the valve. It will hold back a little oil but if you have a big leak out of here then there is an internal problem and you will need to replace the valve.
