    In my Ross steering box i found inner and outer bushings with the same length (1 1/16"). They fit and the oil passage is clear. This box was good for the last 15 years and now i would like to rebuilt it because the oil is leaking a bit and there is a slight play in the sector.
    When i look at diagrams and catalogs i see that the two bushings should not be the same length.

    Any reason why they should be of different length ?

    On the Ross TL V6 box, the shorter bushing goes toward the inside of the housing, and the longer one goes toward the outside. The reason for the different bushing lengths is so that neither will block the location of the oil passageway in the housing which allows the bushings and the sector shaft to get oil.

    In order for the bushings to avoid this passageway completely, a small divot needs to be removed from the larger bushing (see link below). When installing them, be careful to orient the bushings so that the oil passages cast into their inner faces are appropriately positioned with the oil passageway in the housing so that oil can easily flow into the bushings.

    You might want to check out this post on Moses Ludel's website re. the installation of those bushings:

    Thanks maurywhurt,
    My Ross is from a F134 and i watched the presentation by Ludel.

    As i said, with 2 "long" (1 1/16") bushings you have nice oil passageway and i wonder whats the reason for using "short" and "long" bushings combination.

    When I rebuilt my Ross TL box (I started the thread you were looking at on Moses Ludel's site), I did not try using two of the "long" bushings.....but if they fit as you indicate and don't block the oil passage in the housing, I can't see why it wouldn't work to use those instead of a long and a short bushing.

    In any case, I would highly recommend the Penrite Steering Box Lube in place of oil. It's designed specifically for older steering boxes like the Ross TL, and tends to "stay put" and lubricate the sector shaft bushings and the pins better than oil. Penrite is an Australian product available in the US through Restoration Supply Company. If you download their .pdf catalog, you'll find it under Penrite Products at the bottom of Page 24.

    I will use this thread to ask about another issue came out right now:
    Looking at the steering gear exploded diagrams i see there is no oil seal in the upper part, where the tube goes out of the box (and there are shims under the upper cover).
    Today i put the whole gear and tube (after the rebult) in horizental position and fill with 140W oil. Suddenly a lot of the oil leaked from the gap between the tube and the upper cover.
    I never refill oil in that position and it is new to me.

    1. If no oil seal up there, so oil may leak in that position - is it right?
    2. also, it means that the only "defense" from elements to enter the oil in the box is the steering column - right?
    3. If all 2 above are correct - there is no reason to fill oil untill i will attach the box to the frame in the right position/angle...

    I used the Penrite steering box lube instead of oil, which has a much higher viscosity than the oil. Using this thicker lubricant is what allowed me to fill the housing while it was in the horizontal position. (A small amount of the Penrite made its way out around the bottom of the steering column tube later - but very little.)

    However, oil, as you discovered, is much too thin to be able to fill the housing in the horizontal position, as it will simply run out through the housing's upper bearing. Using oil, you will have to fill the housing after it is installed and the steering column is at its proper angle.

    You are correct that the steering column tube is the only thing that keeps contaminants from getting into the steering box oil!

    Thanks maurywhurt. I left a small amount of 80-140W oil inside for the night at about 60 deg. position to let him think if he ever wants to leak from other places :)
    (I dont know about the Penrite you talked about and i dont think we got it here. I will use the 140W first time after almost 30 years of using 80-90W oil)

    I am almost done rebuilding my Ross steering box. It goes on a 62 CJ5. I decided to go full metal jacket :D and increase the bushing area, therefore a more rigid and durable pivot point for the sector. I used an oil impregnated bronze and pressed, reamed and re-opened the oil passage. Also filed a little channel for the oil to spread around. Remember this does not turn at high RPM's at all!

    Is there a p/n for the bushing you used?

    Did you need to ream it for the shaft to fit?
