no it would have been 6 volt originally. not sure if you have the same e brake set up as my 38. with it the problem was not the "tube" but where the pins went thru the clevis (end) yokes all the pins were froze both to the end yokes, the Tube and to the ends of the ebrake cables. The ebrake cables were also frozen inside the cover. Once I freed the pins up and remmoved them from the Tube the tube rotated freely. i'm sure this is as clear as mud. used heat, penetrating oil and big hammer to free the pins. the tube assembly is bolted or rivited to the crossmember so it can be removed but it might not be needed to get grease in there.
