Hydraulic transmission

[obb]

Anyone have any idea on how to properly bleed out air on a hydraulic transmission this is a 1979 international backhoe thank you

Do you want to get the air out of the BH and FEL cylinders? If so, just cycling them through their range of motion several times should expel the air into the transmission reservoir to be released through a breather tube.

I don't think a hydraulic transmission is meant to be bled since it is open to the air through the breather tube.

ok then it must be something with the transmission it just quit moving all at once so thank you..I will look a little further into this problem may be some kind of filter in the transmission that is clogged up I hope thank you again...OBB

Well I don't know if you'd be interested but I thought I would share.i pulled the floorboard out of the tractor to get to the top of the transmission I pulled off a mixing valve for the transmission it apparently goes to the hydraulic transmission torque converter I think, when I pulled the mixer valve off realized that one of the tubes had slid into the transmission apparently the pressure side it has one rubber O-ring and one neoprene O-ring split to slide on underneath it is a still two-piece ring that holds the tube from sliding back in to the transmission so my problem is locating these two still half rings I'm open to any suggestions on locating these parts ps I did add the pitchers pitcher is worth 1000 words how thank you everyone have a great day

My first (and only suggestion) is to take the photos and broken parts to an IH dealer. Try to get as many model and serial numbers off of the tractor that you can so they can look it up.
