    Hi
    I broke the right rear spring on my 9200 international.
    Putting it back together seemed to be going along nicely till the bolts for the air bag assembly wouldn't line up with the new spring (Which matches the old but broken one).
    I could jack the air bag assembly back to fit but the airbag ends up on a bad angle.
    The axle and thus the spring seems to have moved back about 1.5 - 2 inches.

    What to do now??

    Also it seems I need to adjust the front rear axle alignment as well.
    Can anyone help with my alignment troubles??

    Did you align the center pin of the spring correctly into the dowel hole on the axle saddles?

    Can you turn the air bag around? Sometimes the top studs are offset. Here's some Navistar alignment info. I might be able to get you more if you know what kind of suspension you have. If you have a single leaf spring with an airbag, the only one I'm finding in the manual is Hendrickson

    I think I did, yes. How should I check?

    I just set the spring in place atop the axle (didn't have the new U- bolts yet) and attached airbag assembly to the spring.
    And everything looked out of alignment.
    I didn't look to me that tightening up the U- bolts would help pull alignment back to correct.

    Hi
    Thanks for the reply.
    I'll check that.

    The attachment wouldn't open.
    I believe it's the Henrickson system. (I thought it was international's own system, because the castings all have the International emblem on them, but I see from another post it's a Hendrickson)

    There should be an alignment dowel welded to the axle that the center hole of the saddle and block line up with. I'm not positive because I don't work on many International tractors though.

    Hi Ross
    Thanks for sending the picture.
    Yes, there's the alignment dowel on the axle.
    I cleaned up all the parts too to make sure rust deposits didn't affect alignment.

    Hmm... the axle and spring can shift forward in some axles, and we have to use a come along or porta-power to put them back. But the dog bone in this suspension should have kept it reasonably aligned. You could take some measurements from the other side to see where you're off. ihc.PNG

    First of all, I want to thank all who responded to my need. I'm grateful for the help and grateful I found this forum. May I say, God bless you all.

    I'm sort of embarrassed to tell you that my trouble was all caused by failing to install the spacer which goes between the spring and the top axle bracket (see attachment).

    I had all the parts set out in order when I disassembled, but didn't keep them in order when I cleaned them up .

    Needless to say, when everything was put back together in order, everything fit and aligned!

    Thanks everyone once again.
