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.
