Re: flywheel id for part number 3197219

["Ralph Ausmann" <ralph.ausmann@xxxxxxxxxxx>]

Dan,
I don't know...  I've seen this pegged as a 360 flywheel before...  And Tony
Zamisch has some info on this.  See his input on this casting number as he
has come up with several different sets of specs for this casting.  And this
casting is not on a flywheel list that Tom B posted before.

Good luck with this.  Maybe you can check specs on your casting and properly
match.
Do you suspect this may be a part that required finish machining depending
upon the engine is was to be fitted to?

If you post a response to the list, please cc me at d.curtis@xxxxxxx

Hello Listers,
   The question posted recently by Phil Campbell regarding the flywheel with
casting # 3197219 has yet to be answered with 100% certainty, and what you
are reading here is not an answer. Yes, that's right, I don't have a
concrete answer either so I'll add yet another twist, and I'll share with
you what I do know about this particular casting number.

   Being in the parts business, I get to see many things that are more than
just confusing, they're downright frustrating! I have in stock now, and have
seen in the past, THREE distinctly different versions of the flywheel with
part #3197219. If you have one of these flywheels, and you want to follow
along with the description that follows, place your flywheel flat on the
bench with the casting number facing up and at 12:00. (like you're reading a
clock)

Version #1:  #3197219-C
Crankshaft flange recess measurement: 4.500" Counterweight position:  at
7:30
Known to be out of a dead stock 1970  390  4-speed car.

Version #2: #3197219-C
Crankshaft flange recess measurement: 4.500" Counterweight position:  at
4:30
Known to be out of a dead stock 1970  360  4-speed car.

Version #3: #3197219   (Does not have the "-C" after the casting number, but
does have  "E-25" cast in just above the counterweight.) Crankshaft flange
recess measurement: 4.650  (approx. 5/32" larger than the above two
versions) Counterweight position: 9:30
Exact application: unknown

   All cast-in counterweights are one square inch, with the exception of
version #3 which is 1/4" shorter. (length 1", width 1", depth 3/4")

   We know that Version #3 is obviously for a late model 72 or later 360 or
401 because of the larger crankshaft flange recess, and the fact that it has
a cast in counterweight (304 flywheels do not have a counterweight), but
which one is it for? It is NOT for a 1970  360 or 390 because it is sloppy
as hell on the back of a pre 72 crank. I work mostly with 68/70 AMC cars, so
perhaps the answer will come from someone who is either an original owner of
a 72 or later 4-speed car, or someone who has had the unique opportunity to
disassemble an undisturbed original 72/up 4-speed car.

   On the other hand, who knows what the hell AMC did anyway. From the
factory, to the dealership service departments, there are bound to be things
we find today even in original "stock" cars that are beyond explanation. I
believe, however, that 98% of assembly line work was quite uniform, and for
example, they would have used flywheel "X" for one application, and flywheel
"Y" for another, and so on. Most parts are certainly identifiable leaving
little room for speculation.

   Also, CASTING numbers and PART numbers are completely different! You will
not find the casting number off the back of the flywheel in the AMC parts
books. And all casting numbers are just that. They're "cast" in, not
"stamped" in.

   Any explanation, suggestions, or even logical speculation is invited.
Let's have some feedback on this subject. Someone has the REAL answer to
version #3.

Tom, a week ago I posted a question about identifying a flywheel I bought
with that Hornet 360 (from Jason Plastridge) and received no response. None
of the casting lists posted have the number, but now you post your flywheel
number --it's the same as the one I have:  319 7219.  Well, at least I know
it's for a 360.   Love this list.
