manipulation #16Mosler 302-402Group2 ... 3 wheel ... key change ... spring loaded fence

At this point, I've now experienced a small handful of various brands, including....
Sargent & Greenleaf, Yale, Diebold, LaGard, Ilco Unican, LeFebure, VanGuard, and Rench.
So I'm looking to expand this list. Imparticular, I've really been gunning for a Mosler.
You may have seen the breakdown I recently posted on
this one. I found it to be a little
beyond me for now. So it's currently setting pretty in my collection while I focus on this one.
This particular model though, has standard wheels and does not feature Mosler's shutter driver.

Mosler uses a double-pronged spline key to securely join the drive cam and spindle as one solid unit.
Also typical for Mosler is the friction plug: a spring loaded circular delrin piece within the wheel post.
It applies constant pressure to the spline/cam/spindle assembly to insure smooth and proper function.
In addition, I find it really slows down my spinning and also dampens feedback within the contact area.
And one last note... the fence looks to be more or less a roll pin of sorts. First I've seen of one like this.
...and in a very large world... a small stack of joy
flip-sided wheel viewAs always, I begin the manipulation by first gathering some standard info.
CONTACT AREAApproximately 11 incs wideLCP 93 . . . . .

ROTATIONAL CONVERSIONpick-up differences for wheels 3, 2, 1
were:
.2 .... .6 .... 1.2 .... respectively
My preferences seem to constantly change, but lately I've been using a right rotation.
Mainly due to the speed and ease of dialing it seems to offer me, opposed to left rotation.
I prefer to map every 2 intervals, and my readings are now taken within one tenth of an inc.

A profile of the wheel pack as a whole is created, and two clearly defined gates appear at
18.5 and
50.
In this case there exists a "
most likely" scenario. Given the tendency of many locks, there's a good possibility
that the most definitive gate (50) is w3, and the other (18.5) belongs to w2. Obviously, we can't simply assume
this. But if we have to explore all possibilities.... we might as well begin our search in the most likely of places.
I tag gates to wheels through isolation. All this means is that I'm running a
single wheel through the area
in question to see if the gate indication occurs. If it
does, I know absolutely that it belongs to that wheel.
There's no need for a reading at every increment as I've done here... but it helps to illustrate what I seen.
One graph containing two different isolations. First, look at the one on the right:
1+2 @ R18.5 ..... 3AL Or, maybe easier for you to visualize...
R18.5 - R18.5 - ALI park wheels 1 and 2 at the other gate indication (18.5), hoping this will allow
the fence to rest predominantly on wheel 3 as I run it through the area of 50.
The gate appears (
with even greater rate of change than in the initial graph).
Without reservation, I tag the gate at 50 to wheel 3.
Turning our attention to w2 (
next likely wheel to read after w3)
Could our other gate indication at 18.5 belong to wheel 2?
Again, I use isolation to answer this question:
1@R50...2AR...3@L50.2And again, maybe easier to visualize it this way:
R50 - AR - L50.2The drop occurs and I can undoubtedly tag it with wheel 2.
- R18.5 - L50.2And we all know what happens once
2 of 3 gates have been discovered.....
game over
OPEN: L82 - R18.5 - L50.2
. . . . . . . . . . QUESTIONS . . . . . . . . . .I was hoping someone would take a moment to 'school' me a bit.
I'd like to gain a better understanding of Moslers' identification system.
What does each of these series of letters and/or numbers elude to?
Here on the back of the lock body is an eight digit number.

Pressed into the lock's cover plate is "302-402".

And on the tag, another two sets of distinct codes:
No. 479321
