Okay, so the '32 is definitely a different design than the '30.

But part # 195918 Motor Vibration Damper Assembly is specified for all 726 thru 904. Maybe a misprint? Maybe a retrofit?

Tom, (both Toms, Ken and anyone else with a '30 thru '32)
How many bolts does you balancer have, in the front surface ?
Thanks,

Rick,

Mine has Six...

Thanks Tom
We are narrowing this down, now we just need to know about the '30.

I will check mine tonight.

Tom

G'day all, I have fitted my 533 vibration dampener with a timing mark and pointer and it works fine without any oscillations, it has obviously been been fitted with a later dampener. My spare 533 engine has no dampener but has a solid metal pulley with the hand crank scroll . I am not doubting that the 733 has the friction discs. I am hoping that someone can come up with a Packard Motor Company explanation on how it works. A very interesting thread and we are all learning something. Best regards Peter Toet.

Another thing that complicates this, on '29s, is that the belt-pulley is in front of the balancer on the Super-8 engine, not behind it like the Standard-8, so you can't see the bolts in the balancer after the Super-8s is completely assembled.
Tom, I'm assuming your 733 has the Standard-8 engine, (with pulley behind balancer), correct?

Rick,

Mine is the 833 and the pully bolts on the front of balancer.

You can see it somewhat in this picture

Thanks Tom, I was asking the Other Tom (with the '30), I knew you have the Standard-8 in your '31.
What we need is a Few More 'Toms', with early '30s cars, then we can have a Real Party. LOL
Oops, I just noticed that you said the pulley was on front side, which is backward from what I thought the Standard-8 would be, since it's on back side in '29. Now I am Confused ????

Likewise the '31 Standard we have here at the shop, as well as all 4 '32 Standards and a '33 Standard all have the same dampener with pulley in front. I was going to post a pic but Packin beat me to it. They all have six screws holding them together, tuff to see with the pulley in place but we've taken enough of them apart to remember.

Turnquist's book also shows a Super 8 chassis from '36 with the same setup. Also same setup on '34 Standard.

Okay, I know why the pulley is on back side of balancer on the '29 standard-8. It's because of the Side-mounted Water-pump. The '29 Super-8 and all later models had Front mounted pumps.
So if that's true, aren't the balancer bolts hidden by the pulley, on the '30 thru '34 ??? Or do they go thru the pulley also ? They are hidden on the '29 Super-8 and don't go thru the pulley.

PACKARD by KIMES on page 300 shows a very clear pic of the 733 motor with pulley in front of dampener. According to Kimes's book the 7th series were the first engines to have the double fan belts to correct a perceived weakness in the 6th series engines. So the conclusion is inevitable. All Packard 8 engines from 1930 thru 1934 at least shared the same pulley and dampener system. Speedy, if your car is different it must have been retrofitted at some time. Do you have 2 belts or 1 on your '29?

Please read my post before your last.
That's why the '29 standard-8 is different.

Man, Since we got goin' on the pulley thing, I've lost track where we were on the slip-balancer question? LOL

Confusion reigns. Speedster, the above applies if your car is a 7th Series. If it is a 6th Series the single belt system is correct.

Rick,

If you are talking about the Six Bolts on the Balance they are on the outer circumference. I can take a better picture of mine tonight if you like. I have it off the car all nice and painted now…

I have never worked a '29, well, did paint one a few years ago so I can't comment on the 6th series and earlier. Apparently the dampeners on these functioned differently. Does your car have a single belt?

Are the balancer bolts hidden by the pulley, on the '30 thru '34, Or do they go thru the pulley also ?
If they go thru the pulley, then the 6 bolts you have been refering to are actually holding the pulley on to the balancer, not holding the front and back halves of the balancer together?
The 4 bolts, in the '29 balancer, I was talking about, hold the balancer parts together and provide the clamping force on the clutch disks between the front and back halves of the balancer and the inner part. These front and back halves make up the Outer part of balancer and they spin on the inner part, which is attached to the crankshaft by the large center bolt and a Keyway.

Yes, Both the Standard-8 and the Super-8 have a Single belt.

Tom, I missed your post before about the bolts being at Outer edge. So if they don't go thru the pulley, and actually hold the balancer together, then it sounds like it may also be the Slip type balancer ??? Have you had it apart and saw the friction disks inside or is it the vulcanized type that Can't be taken apart? A picture would be helpful. Thanks,

I think I've thought of a way to tell the difference. Is there a seam in the middle of the outside edge, all the way around the circumference, in yours. The slip type have that seam, where the front and back halves separate. If there's not a split seam there, then it's Not the Slip type.

Rick,

Never had it apart I was afraid to so I had it cleaned up and now have it nicely painted black.

Mine does have the seam all the way around the outside edge.

Will snap some picture tonight...

Here's a pic of the one on my spare Standard-8. The seam can be seen in middle (note the pulley behind balancer and you can see head of 1 of the 4 bolts thru front)
(There's a small gap (about 1/16") between pulley and balancer, so the outer balancer is free to move without touching the pulley. Pulley is keyed on the crankshaft, as is the inner part of balancer.)

Wow, what a thread. Sorry for the late reply. I was out socializing last night. Weird, huh .

Anyway, please find attached a photo of my vibration dampener and pulley arrangement. There are no bolts going through the vibration dampener outside of the pulley. The pulley itself has three bolts that go through it to the dampener. Do those bolts force the dampener to spin at the same rate as the pulley?

Also attached please find the shots of my distributor rotor shaft and distributor shaft. The 'tabs' and 'slots' on this system are definitely offset and are so from original manufacture.

It has the seam in the middle also, so that sure looks like a Slip-balancer to me. So I don't think a timing-mark will work.
I lightened the pic so we could see it a little better:

Also, here is a scan of the 7th series vibration dampener diagram from the Service Parts List
