Weird issue with mainshaft

[rotorstart]

Folks,

I'm at a loss. I'm done with reinstalling the new gears ( after a crash). I look at the main shaft and somehow the line on the main shaft that's supposed to be sitting on the bearing block, is now hanging at the middle. I'm attaching for your reference. The bottom hex screw is installed with the nut on the bottom gear. Everything else seems to line up correctly, except that I'm seeing this line up there.

Any input is much appreciated.

Not trying to upset you..is that main shaft installed upside down perhaps?

I need help, so anything is appreciated. Main shaft upside down? Negative. The reason I know for sure because near the top of main shaft, I have 3 screws up there to hold the shaft to the head block. The bottom end of the shaft, there's only one hole to put the screw through the main gear. Please, any other idea where I should check? Thanks.

If you have the 3 holes at the top of the head and the single down on the auto gear, looks like Align may have just drilled it backwards when it was made.

I assume you bought a pack of two....Do you have a spare to compare it to ?

The holes drilled on the wrong sides would be a new one for me, But I wouldn't put it past em'
