Part Number ID Help

[68stang289]

When I got my first car 6 or 7 years ago it was a 68 289. Somewhere along the way I picked up a new harmonic balancer/damper for the car. I don't recall ordering it from any of the parts suppliers and now that I look at it, it has a Ford oval stamp on it. The number listed on it C82E6316 B1 1200. Anyone able to identify this for me? I tried to google search it but not much came up. I would assume (probably incorrectly) that the reproductions available don't have the Ford Oval stamp on them?

^ You can see the Ford Oval there. Thanks!

C8 could stand for 68
An oval stamp with ford logo would indicate that it is a orig ford part.
Maybe you should call a ford dealership and inform about the p/n.

It's probably on original small block for balancer, could be that it has been rebuilt. There's several companies that rebuild them.

It's probably an NOS part. IIRC, back in 1998 Ford dumped all of their classic Mustang parts inventory onto the aftermarket parts houses. Prior to then, you could in most cases simply walk in to your local Ford dealer and order whatever part you needed. Some parts were no longer available, but a LOT were. The aftermarket parts houses (NPD, etc.,) bought all of the inventory and sold it alongside the reproduction items. Eventually most of the NOS stuff sold out and only the repro items remained. Your balancer is probably one of those items.

Hmmm, good to know. I just went through all the copies of the parts receipts I had for the car (I kept copies since it was my first car) and I had no record of purchasing a balancer from any of the parts suppliers. I must have picked it up at one of the swap meets.

Would this work for any 289/302? Other than a hipo that is (because I would assume they had a different balancer?). Appreciate the information guys!

Assuming that PN corresponds to a 289/302 engine. It was likely PN coded as a 302 part. I would think that a 289 balancer would have an earlier casting number.

It will not work on a newer 302 "roller" motor, but otherwise should work on an early 289/302.

I've found this website helpful: http://www.mustangtek.com/pulley/Balancer.html

Are you sure it isn't C80E instead of C82E ? That would match the 68 302 balancer.

Great website buening. I just pulled it out to look at it. The part number is actually C8ZE6316 (my mistake). It has timing marks as follows - ATC 10 TC 10 20 30 BTC. Cast into the metal on the side that would mount towards the engine are the numbers 1, 4, 9, 2, 8, 1 all separated by spaces.

This is all I was able to find while googling the correct part number

The numbers I'm talking about are just like below and that is a replacement 289 Hipo balancer (picture of hipo balancer from the mustangtek website). That being said the balancer itself does not look like that, it's much thinner.

Mine looks almost identical to the C5AE-6316-A2 which is the 65-67 289 according to that website, except that the timing marks are different on mine.

That website lists inner & outer balance dampers for the 302. I'm assuming they mean internal / external balance? If so, weren't all 302s external balance?

My guess would be the location of the weight on the damper (towards crank or towards radiator). Just a guess though.

It appears the C8ZE-6316 is actually the engineering number. The part number for that balancer should be C5OZ-6316-C and I believe is a replacement part for the 289 Hi-Po as you've stated. What part is thinner?

I agree that C8ZE is the engineering number. I don't believe it's from a hipo though as the hipo balancer appears to be thicker (for lack of a better phrase) than what I have. Here is a close representation of what I have:

This is the "thickness" of the hipo balancer that I'm talking about:

I'm guessing it's a NOS 68 289 balancer the more I find on it. The fact that it has B1 at the end of the part number is what also makes me think it's not a hipo balancer. Unless the B1 is a production date in which case I'm back to being confused, haha.


I also found this which lists the 'B' number in it. http://www.fordsmallblock.com/PDF/e-5.PDF
I'm going to be tossing it up on ebay soon and I just want to make sure that I don't misrepresent what it is to anyone.

My books have a casting # for 289 (1968...all applications) as: C8ZE-6316-B, with a part number of C5AZ-6316-B. I believe that is for the non-HiPo 289 crankshaft balancer. The B1 suffix is likely a slightly modified change introduced later and is not NOS.

I wonder if Bob Mannel's book says something? Yup...Page E-5, says B1 suffix is correct for casting. A picture is shown on page 8-9.

Looks to me like you have an OEM balancer!

Please forgive my ignorance here but what is the difference between an OEM balancer and a NOS balancer? The NOS is an over the counter replacement part? The balancer I have looks like it has never been used or even mounted on an engine.

 

[buening]

Ahh, didn't catch the B1 part. Sorry bout that! It indeed looks like you have a non-HIPO 289 balancer. Wouldn't the difference between a "B" and a "B1" part be that the "B1" is a Revision to the original "B"? I'd expect the B1 to be a replacement part and the B to be the OEM.

OEM is Original Equipment Manufacturer, while NOS is New Old Stock. If the part has never been used, the two are often the same. OEM usually refers to used components or service replacement parts, whereas NOS (strictly speaking) were assembly line parts or replacement parts without having been modified later. NOS parts usually refers to what was available in that year of manufacture.

So suppose you have a 1968 289, and needed to replace the balancer in 1973. Ford would have that part in stock, and it likely would be a service replacement part (slightly different due to suffix coding). If you had to do the same in 1968, legitimately, it would be called NOS.

NOS has a loose definition, and some use it as any unused part manufactured or sold by Ford over the counter, regardless of how many years after the part was originally used.

Gotcha. Thanks for the breakdown. I would be grouped in the latter where I assumed NOS parts were just unused parts manufactured or sold by Ford over the counter. What you said makes a lot of sense though. Thanks for all the help guys!
