    Maule Tailwheel lock ring spacer drilled off center?

    Have this good pneumatic Maule Tailwheel assembly.

    But the spacer half hole that is machined into the I.D. that fits over the dowel pin on the side of the pivot shaft is not machined center.?

    As in not centered across from the lock receiver slot.

    This makes the bellcrank horns not 90 degrees from aircraft longitudinal axis. It ends up about 12 degrees off center.

    When I look at my other old unit, it is machined centered across from the receiver lock slot.

    Looking at pictures of other TW-57 lock rings online at spruce and wag I don't see the half hole machined at all.

    I also see the two drilled holes top to bottom of this newer lock ring like the ones in the wag and spruce picturese. No holes in the old narrow width smaller lock ring in the picture.

    Seems like a mismatch of parts maybe that someone machined the half hole in the lock ring to match up with the older design?

    See picture. Hope it uploads.

    Story?

    Just make the chains that connect the rudder horn to the tailwheel steering arms different lengths. Maule's are not precision assemblies.

    Best of luck,

    For what ever it is worth, it is my understanding that at one time Maule back in the 80s had these parts machined down in Mexico, and many were hand fit and a lot of the parts were not interchangeable! I thought they had resolved this problem some time ago? But you may have tail wheel parts from back in that era? Dave

    Oh Boy. All the other aspects of the Maule Tailwheel I like.

    Thank you Fellows.

    Mike, You have parts from two different models, acs sells both, look closely at the parts breakdown. If you have time bring it by the hanger may have them on hand.

    Nice jungle boots! I have many memories of the blisters breaking in new pairs of those. Like slippers after the blood sacrifice is complete:)

    I would say those are broken-in.

    I'll stop by in April Jeff. I'm stuck up here in Newark till after the 6th. Training may pop in there too. Thought you might know about that, thought of asking you if you had seen that with all your tail wheel building experience. I'll look at those acs diagrams better too.

    Been away from the computer for a few days.

    That's my second pair of jungle boots and I've been wearing that pair since in my late 20's and I'm 51 now. Love them. Very comfortable and agile in the shop.
