Hi Les,
The hole in the end of the shift rod is eccentric so that the roll pin can be aligned with the diameter of the rod. I presume it is easier to drill through a circular rod this way.

Subject: [Syncro_T3_Australia] Diff Lock Actuation
I pulled my rear diff lock actuator off, believing that it was cactus. It wasn't, it operates properley. The problem lay in the fact that it wasn't connected to the shift rod - no roll pin!
I have never had this apart before and I am amazed to see that the hole in the end of the shift rod is eccentric. Can anyone confirm that this is correct? I just can't see why it would need to be eccentric. (It certainly costs more to manufacture this way.)

I and others have discovered to our chagrin that during the re-assembly
stage, in the event one drives (light hammer) in but inadvertently
misaligns the roll pin re-insertion with its mating recess on the
actuator rod, it's quite possible to shear off the end of the actuator
rod. Means you have to buy a whole new actuator. Also then the broken
off portion of the rod is inside the hole in the tranny case, using a
strong magnet may draw it out ok. But heh, as they say ... practice
makes perfect. Good luck.
Cheers.

Gday Les,

stage, in the event one drives (light hammer) in but inadvertently

Here's another tip for later when you go to reinstall the starter motor
and need to re-attach the heavy cable (eye terminal) and the lighter red
cable to the solenoid. Can't help you with the heavy cable, that one is
bad news to re-attach so you just need to exercise the gray matter how
to do it. Let me assure you, no amount of praying to the almighty will
help ... haha.
This concerns the red cable coming from the engine bay, through the
firewall and ends up as a push-on connector to the terminal on the
solenoid. This is a real pain as well to re-attach with zero room to do
it. Suggest you get rid of the push-on connector on the cable. It can
often be unreliable for continuity at the push-on connector anyway.
Permanently solder an extension length of similar size cable to that
solenoid terminal, run the cable back along the top of the starter motor
( a very snug fit against the starter motor housing is best, hold it in
place with zip ties, then terminate this extension cable at or just
through the firewall. Now fit male and female inline connectors at that
position, male to the extension piece, female to the incoming original
cable. Now you have a very easy disconnect/ reconnect of that cable
serving the solenoid and one less cable you have to battle with during
starter motor R&R. Until you've attempted this procedure, you won't
fully appreciate the value of this mod I'm suggesting.
Cheers.

Reading the USA syncro forum awhile back, a syncronaut with this problem
came up with the mindbending suggestion to get in there and start
drilling out the hole in the diflock shaft the broken off bit was
located in ... that was his best idea? Haha ... at times , the posts
can produce some pearlers eh.
I guess there was no issue or need to test the diflock function when the
gearbox was out .. at the hourly rates they charge, you probably agreed
anyway ... time was of the essence.
Make sure the red rubber bladder isn't perforated/split ... you'll need
a new actuator if it is.
Cheers.

reinstalled.
