  • 52 8N steering gearbox
  • I'm fixin to replace both leaking seals on sector arms on my 52 8N (the newer box) I have every manual available. Gearbox is still installed in tractor, I've pulled sector arms but need to pull outermost seals, I cant reach em with any seal puller I know of because the sector shafts.
    Manuals don't address just this nor does anything I've seen online..
    I really don't wanna remove entire gearbox at this time, any advice to make this thing as quick n easy as possible??

  • You don't have to remove the box to replace the sector shaft seals. You do have to pull the sector shafts. Take the two bolts that hold the cover with the adjusting screw in the middle out and the shaft slides out as a unit. Left shaft assy comes out right side, right side shaft assy comes out the left side. Two seals each side. There is a big O ring on each cover and a small O ring on each adjusting screw. If there is any play in the bushings it will leak again in short order.

  • Thanks Deano, that's the quick fix I was looking for !
    Been workin on this thing off n on for several months and I enjoyed it better when hood assy was off.
    I also found that a conical puller is best for sector arms when hood is on tractor.
    Only thing I dislike about 8N's is that dang hood....

  • I kind of remember reading a while back that the whole unit must come off to get at seals or races.
