filter position
Most hydraulic systems I have worked on have a big strainer inside the tank to catch the bigger stuff and a fine filter on the return side of the valvebank. Some of the bigger systems have the strainer, a suction filter, and a return filter.But a real suction filter is big bucks. Anyway your filler should have a dirt trap inside to take the big stuff out of the oil. Most people would not be filling their splitters all that often, so the chance of getting rust ect in would be rear except if your oil container or pourer was dirty.The filter on the return side stops any nastys getting into the tank, and being sucked up and fed around the system again doing damage
I don't know, but to me it makes sense to put it there. You don't know what is going into the tank, there could be rust flakes or something that fell down the fill hole that could ruin your pump or valve. Putting the filter after the pump I think would be disastrous, and a very expensive design flaw. But again I am no engineer, so I can't say for sure where the filter should be.
