Sounds like it has a gut full of air which can be compressed whereas hyd oil cannot and is not circulating. must be some way of bleeding system

4496 CASE TRACTOR .Ran out of hydraulic oil , filled up and bleed lines , still have no steering and the brake is out ,.What valve is locked in ?

by bleeding lines where exactly did u do this ? , the place id try 1st is right off the pump to the dist block (carefully!!!) if no pressure there then a more aggressive repurdge of hyd sys is needed using another machines hyd system connected to remotes inputs off the dist block
reason 4 this is that hyd oil pumps don't just pick up oil again when run dry an have to be helped to pressure up again , Also another possible cause is that pressure relief is stuck open , this doesn't allow any pressure to build up

1952 Fordson major diesel hyd fluid gets into front tranny

Sounds as if the input shaft seal for the hydraulic pump that is driven off the transmission is bad and allowing the fluid to enter the transmission housing. When the fluid gets too full it aerates and causes the "root beer float" fluid.

How to remove oil sump pan on a kia sedona 2.9

Having worked on these design nightmares, it's rather difficult. You'll have to use a cherrypicker engine hoist, disconnect the motor mounts and raise the engine to get that bit of space. There are just to many suspension and cross member parts in the way otherwise. A repair manual such as Chilton/Haynes from your local parts store (and for your make/model/year) has the step-by-step instructions.

air bleeds out with the piston movement so with the piston movement air is put in and then is evacuated as the piston come back down. an indication of air is a jerking motion of the rams as pressure is built up and the ram moves which lowers the pressure until it gets up again. I would be having the pressure relief valve on the pump checked for correct setting. I would also be having the hydraulic hoses checked as they have been known to fail internally and block of the oil flow.
