I need to know what the National number is for the shaft seal for the hydraulic pump on a 190XT. I have the AC number somewhere but need a National or CR number. Or just the dimensions. I probably have a seal for it but don't want to take the pump off without knowing for sure that I have a seal here. I use this tractor about every day.

Dave, I have the old seal from my 180 in front of me. I would assume they are the same. No number. The demensions are-.250 thick-1.375 OD-.875 ID. They are a hi-pressure seal. I hope this helps. Happy New Year.

Well, according to my manual, the front seal for a 190 pump is not the same as the 180 pump seal. Seems it is a seal assembly. Anyone know where to get one. Don't have an AGCO dealer close. If just the seal can be changed please let me know.
