240 hydraulic oil coming out vent

kfnut · Apr 17, 2016

Thanks to Jim I got the hyd. oil drained , installed newly acquired strainer and put in a bit over 1 gallon of hydraulic fluid . I know it takes 5 1/2 quarts but it wouldn't take it , so I stopped and was going to crank it up and circulate the fluid . After a bit ,fluid started coming out the vent . Can anyone tell me what to do ?
Thanks

I have thought about it and decided to let it run and overflow just to see if it might be over full . It did slow down for awhile but the lift is not working now . Before I started it did move a little . Help !!!

If the oil is coming out of the vent, it's not going into the crankcase, but it won't hurt to check. Only takes 2 seconds. Pull the dipstick. If it's over full, then its getting into the crankcase.

That won't fix the blowing out the vent problem. That much I know. What will fix the blowing out the vent problem? I don't know. Sorry I can't be more helpful.

Only thing I can theorize is there is a blockage somewhere preventing the pump from sucking oil and it's just pressurizing the reservoir with air, pushing oil out the vent.

IT looks like it is going to the crankcase . The oil level is a little high . It seems I get about 10 minutes on a oil change . This will be the third time .
Should I get a kit to redo the seals or just bust the bank on a new pump ?
