If that's for the 4U/5U D2, part of the 2H6713 hose and fitting group shown with the #44 hydraulic control the o-ring part number is a 5F1678. Trade size is a dash 214.
Thanks OM Yes it is for a 5U with a 41 two valve unit.

5F1678 is still correct for the #41 at the cylinders only.
Thanks OM

OM, the 5F1678 was too big. These O-rings are on the cylinders and 4j5140 were the ones that worked
Thanks again
Chuck C
I checked again and the parts book shows 5F1678 at the cylinders and 5F7054 at the fender. I suspect your connections have been changed.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
