    Fitted an open drive conversion to my Ford Banjo rear end complete with breather, it constantly seems to be spitting gear oil out of it. Do I really need one? Peace 8BB

    Is it the one that Speedway sells? I just put one on the '32 and haven't had any problems. Where is it spitting from?

    Hi, it's spitting out of the vent pipe, maybe i need to vent it up instead of down so only air not oil get out??
     

  4. I would say that is your problem.

    I had a venting problem, so I put a length of hose on the vent and tied it up to the cross member. Then I heard the vent should be on the right side of the banjo as the ring gear slings oil to the left side. That could be your problem. I plan to move the vent to the right side when I stop screwing up engines for a week or two.

    OOPS, I just saw your picture. I'd move the vent to the top bolt of the banjo.

    I got the HRW one a while back,
    came with the same breather with a small hose barb.
    (replaced one of the banjo bolts)
    Ended up putting a small bottle on the end.

    However,
    the oil is spinning constantly in the banjo,
    If I did it again, or fixed it,
    I would put the breather on the axle tube,
    like on newer rearends,
    where there is no turbulence.

    OK then thanks for all the input and so a move of the vent to the top right bolt with the pipe fixed up to the rear crossmember should do the trick right? and is that the right hand side from the front of the axle or the rear. Peace 8bb

    Looks like he has it on the right side. Ask those guys from Idaho that are on this site. It looks like their vent.

    So does a stock banjo breath up through the torque-tube and out into the u-j housing and transmission? Or did Henry just not think they needed a breather? Thinking about it, what breathers do original open-drive pickup rears use?

    That looks like one of our older open drive kits. I would suggest putting the vent in the axle housing, as was mentioned. We initially tried to make the kit where someone would not have to completely dis***emble the rear end. Venting in the banjo had limited success, so for the last several years we have included a 1/8 NPT vent for the axle housing. You can put in a ****** and a hose, or use a vent out of a late model rear end.

    The stock rear ends vented through the torque tube and transmission. I was just looking at a pickup open drive rear end today, and did not see where it was vented. Maybe that's why it was leaking so bad around the pinion seal.

    Let me know if you have anymore questions.

    Thanks for the info guys, i'll move the vent from the banjo to the axle housing, just gotta find a way to do it without taking it apart so it doesn't get swarf in it when i drill and tap it for the vent fitting. Peace 8bb

    I notice that its a '36 housing, but what are the other brackets for?

    The one near the centre is the same bracket a friend has on his, and the one one the right of centre is completely unknown to me.

    I have 2 '36 rears, and one 48 open banjo rear, and all lack these brackets

    Hi Stovebolt, that axle and all the running gear came from a 1949 Ford Pilot Shooting Brake
    [​IMG]

    I modded the axle by splitting the bone from the hanger and making those mounts to hold the bones and the shocks, the spring is still hung from the original carrier in it's usual position as you can kinda see in this pic and the bones now mount inside the rails

    [​IMG]

    All this was to get the ch***is low but to have room inside to sit low under the screen and also the pilot rails have a bigger natural kick up on the front which when used will the dropped and filled axle puts her pretty low. Peace 8bb

    I thought the pilot had a different centre compared to the US version - 3 spider gears, co****r spline on the pinion, etc etc.

    Hey if the Hot Rod work Conversion works on it - well that opens up options for you Limeys and us Aussies - we all got Pilots.

    What about the bracket that goes horizontally toward the front of the axle?

    The kit all bolted up like a pie ce of cake and That bracket point to the front was for the handbrake mechanism, this is bearing in mind that it still had mechanical brakes on the rears, put some 42 ford on the backs now, bolt on job with the big five spacing drums used. peace 8bb
