Is this shift shaft damaged?

[indr]

This is where the shift arms are riveted:


And there is enough play in the riveted area that the "shift mechanism arm" (left) and the "over shift limiter arm" (right) can easily overlap.


But they usually don't.


Neither of the arms look deformed or bent in any way. It's just that there is too much play where they are riveted.

Replace it?

PS: I posted this same question on another forum, and a member pointed out that this may be by design to prevent binding. So, anyone here that has split the crankcase to confirm or deny?

There is no way that they can take the overlapped position shown in pic #3 during normal operation.

It is a simple ratcheting system that works both ways.

This article describes several systems:

I wouldn't worry at all.

I'm just worried of the side-to-side play of the arms on the rivet.

The service manual doesn't mention the condition of the rivet:

"External Shift Mechanism Inspection:

•Examine the shift shaft for any damage.
If the shift shaft [A] is bent, straighten or replace it.
If the splines [B] are damaged, replace the shaft.
If the return spring [C] or pawl spring [D] is broken or distorted,
replace them.
If the shift mechanism arm [E] or over shift limiter [F] is
distorted, replace the shift shaft.

•Check the return spring pin is not loose.
If it is loose, unscrew it and apply a non-permanent locking
agent to the threads, and tighten it.
Torque - External Shift Mechanism Return Spring Pin: 19.6
N·m (2.0 kgf·m, 14.5 ft·lb)

•Visually inspect the shift drum pins [A], pin holder [B] and
pin plate [C].
If they are badly worn or if they show any damage, replace
them."

The shift mechanism arm and the over-shift limiter will be always separated and aligned by the drum's plates.

Let's wait for others to post, I may be wrong.

I will be doing stuff in the garage this weekend. I will see what mine look like
