    I just noticed you have 5 springs, It might unlock/turn a bit easier with 3.

    Installed Pin, cleaned all parts, replaced with new tire. Worked for one sortie, then same issue with no right response. Going to take Fancypants suggestion and go with a new assembly. Missing valuable instructing time with my daughter. Anyone have suggestions/preferences over different types of assemblies? Maule, or ABW, or Scott 3200 again?

    abw you can even ship yours to them and they will replace what you need, I think they also offer a rebuild kit... maybe..

    I asked in my initial post for a picture of your steering arm on the fork from above after the grease was removed. That would show what your issue is.

    I was thinking the same thing. Difficult to tell from this picture, but it looks like there is a shadow, or groves, that could catch the spring #18 after the pawl kicks it loose. If I’m not mistaken, a second grove here would prevent a right turn.A1F2162E-92C2-4C2C-9353-5B5954950371.jpeg

    Steve - Thanks, some how I missed that request. Think I'll get a new assembly and rebuild this one and sell it. Main issue is my daughter is only home two more weeks and I'm trying to get her to solo before she goes off to grad school.

    That time is priceless. When you get the old one apart post up some pictures and we can help work you though it.

    .IMG_2816.jpgIMG_2820.jpgIMG_2819.jpg Picture of the assembly apart, grease cleaned with new pin. Doesn't the pin seem to short? Barely catches the copper ring.

    The pin should be flush with the raised portion of the fork. Some early Bushwheel 3200s had the bore to deep and you had to make a longer pin or I would pop a spacer with my Whitney punch and drop it in the hole prior to installing the pin. If the washer doesn't fit down tight against the fork and retained by the pin it rotates over the pin and then jambs the whole rotating assembly.IMG_20180710_125635.jpg

    Steve. Do the grooves on the steering arm look OK to you?

    That's surely what's happening. for some reason it always happens to affect the right pedal/direction. Left steering was still fine. what type of materials can I use for such a spacer?

    It looks ok but do you have slop between the arm and the fork like the video I posted? Is the tailwheel not unlocking in either direction?

    No slop noted per your video. A couple more pin pictures. IMG_2807.jpgIMG_2805.jpg

    The groove that the thrust washer sits in looks messed up to me. Should be a nice tight fit.

    Good eye. The groove on my fork is not near as sell defined, causing the thrust washer to ride up. I think that must be the issue. My thrust washer doesn't fit snugly at all.

    New fork and probably a new thrust washer because it has probably gotten rounded off edges by now.

    Wear yes, but the pin can be adjusted in its bore. Drill a small hole in the fork below the pin and either drive it up with a punch to be flush, or remove, invert to expose a new face, and replace with a shim below as Steve notes.

    Bend flat spring out some Hope it doesn’t break. See how it’s out more on one side.

    Forum - Installed a new ABW tailwheel. Previous postings and videos have warned against springs/tension too tight between steering fork and empenage. Please see pictures. Springs seem too tight. What is best way to relieve some of the tension? Chains are already at longest setting.IMG_2830.jpgIMG_2829.jpg

    if you put some eyebolts going down from the rudder fork you would gain some length.https://www.aircraftspruce.com/catal...boltsan43b.php

    Add a link, or squeeze the links to lengthen them.
    Or get some different pitch chain.
    One local hardware store here has 2 or 3 different pitches of sash chains.

    How tight are they? Jack it up and defect the rudder till it breaks the tailwheel over. Is the chain trying to bend the steering arm? Like posted you can use another link or an AN42B-6 eye bolts help elevate wear.

    Maybe a little late for this,
    but I woulda got the #3224A t/w assembly with the upturned arms.
    I think the arms are a bit heaveier duty,
    plus the upturned arms give a better pull angle for easier steering on a Cub.

    You'll probably want to reinstall that leaf spring adapter so the head doesn't shift on the spring.
