[R-390] Removing Megacycle Change shaft

[Jacques Fortin]

Hi Jordan,
Not sure about this clamp ID, but it must have a 13/32" hole to fit the gear
part that it have to hold to the shaft.
See attached picture.
The ultimate problem that Paul is facing will be to remove the broken clamp
there without damaging anything else around.
Using a two-part clamp is a good idea, medium hard to machine, but there can
be other hidden mechanical damages in his set.
We never know what happened to these radios before.
To maintain (or restore) those requires both electrical and mechanical
skills.

IMHO, Paul should attempt a gearbox disassembly, cleaning and reassembly
(Y2K-R3a manual Chapter 10).
At least, he will be able to catch any other marginal mechanical flaw within
during the process.
This is one of the worst case I seen so far: a clamp broken at the worst
possible place, but.. any other broken clamp within the gearbox will require
disassembly, anyways.

There is other "stupid" damages I was able to see in my "spare" EAC RF deck
yesterday night: some of the clamp screws heads are "eaten" internally, most
probably because someone tried to use Allen bits instead of Bristol ones on
those.
That one will be due for a complete overhaul, I believe: it is completely
gummed up, also.

PAUL: just a comment...
The answers you provided came to me OK directly to my email address, but the
same text did not "passed" thru the forum: the postings came to me "empty".
I cannot tell why, but have a check...
