Kevin,
The guts of wheel pilot not complicated. Remove from wheel and pop the two
halves apart. You will see the the lever/cam which engages is held in place by
very small Pins which can sheer off and allow cam to move freely independent of
lever. I suspect this is the problem. You will need small push pin or drift
to remove the pin and broken off part. Back end of small drill bit may work
for you. Or heavy needle.
I took broken pin to a local Fastenal store and bought some replacements cheap.
Hope this helps. Just tear into it and you will figure it out.

Subject: Stus-List Older style Autohelm wheel pilot popping out of gear
Date: Sat, Dec 27, 2014 5:02 PM
My older style, black box, Raytheon St4000 (Mk 1?), wheel pilot started
popping out of gear randomly. The lever that engages the wheel is popping
up on it's own and not engaged when this happens. Does anybody have
insight? This is one of the few pieces of kit I haven't had to fix yet.
While we are at it, if you have working spare parts, especially a wired
remote, I would be interested in them.
The control has looks like this :

And the wheel drive looks like so:

Thanks!
