1256 MCV PUMP in Technical IH Talk Posted May 2 I thank I got oring blowed on the 886, steering quits when you turn tractor up hill. So I was thanking of putting a new pump on it while I had it apart since its got a TA. Steering has quit on the 1256, hadnt had time to figure out whats wrong with it. Just wondering if they would interchange. Thanks for the replies.
