460 Ford Harmonic balancer

[WZ JUNK]

I need a reliable source for information on 460 Ford Crankshaft harmonic balancers and water pump/crankshaft V belt pulleys.  My engine was originally a 1969 429 version but it is now a 30 over 460 or 466 cubic inch.

Some engines of this version were internally balanced and some were externally balanced.  I have no idea which one I have.  I understand that both versions can use the same harmonic balancer but I am a little confused.

I need to come up with a balancer and pulleys to drive my alternator and power steering pump.

I need a little help.  This Ford stuff is new to me.

John, this is from 1977 so take it as such. From what I remember, only the 429 cobra jet was counter balanced, all others were neutral. I installed a standard 429 from a Tbird into mt 67 gt350 so I would have something to drive to work. Another young person story. The Ford dealer sold me a counter balanced flywheel. I put it all together and it shook terribly. I pulled it back apart and took the flywheel to a machine shop. They machined the counter balance off and life was good. I used to keep a box of pulleys around because every engine was different. If you can get the water pump and balancer to line up, you can use spacers to move the alternator forward if necessary. This is all I remember.

The engine was partial dissassembled when it arrived.  I think the harmonic balancer was on backwards and I put it back just like it was when it arrived but I am not sure it is correct.  None of the pulleys line up.   Is this the correct installation or should it be reversed?  The other side has a snout.   Tomorrow, I am going to find an engine for reference.

John, the one's I had were all 1978 and older. The balancer had a snout that went into the front cover. I have in front of me a Ford catalog and it lists M-6359-d460, spacer with counter weight for 1979-1997 externally balanced 460 engines. Ford sells a balancer that is neutral balance with no sheaves. If your block has this casting number: D9TE-6015-AB, then it will be counterbalanced on both ends.

Thanks,

This is getting really confusing and I will have to sort it out as far as the balancing.  I do not have the sleeve with the counterbalance.  Mine is simply a sleeve that goes between the harmonic balancer and through the timing cover.

I believe my engine was originally a 1968 429 that now has been converted to a 460.  

The internet has not been my friend on this one.

Somebody will know the casting number of the crank that is counterbalanced. Sounds to me like pulling the pan and looking for numbers will be the best way to determine what it is. You could still have the early block but a later crank in the conversion. The 69 429 that I had in my 67 Mustang for a while had a balancer that looked I believe I bolted pulleys to. I found this listing of neutral balance 460 cranks:  
Try the 3rd counterweight down from the snout, along the leading edge or trailing edge of the counterweight...not on the radius of the counterweight. You should find a 2Y, 2YA, 2YAB, or 2YABC...might be covered in grease and grime, so wipe clean with a rag and look closely.

On the other hand, if you have very late 3Y (external balance) crankshafts, then there may be no such markings on them at all. I won't get into the details of identifying these late 3Y cranks because you sound certain that you have internal balance crankshafts.

(From and earlier post): One of the crankshaft countrerweights has alphanumeric markings stamped on it's edge, and these markings identify whether it's a 429 or 460 crankshaft.

429 = 4U, 4UA or 4UAB

460 = 2Y, 2YA, 2YAB or 2YABC....or 3Y or 3YA.

Also, for quick identification of the crankshaft, you may look for the nodule or embossment between the first main journal and counterweight. The 460 is embossed there, while the 429 is not:


I found this: C8SZ-6312-B .. Double Sheave Harmonic Balancer / 7" diameter / 1 7/16" long / Marked * with ID number: C8VE-A or C9VE-A

Applications; 1968/69 Galaxie/LTD/Thunderbird 429.
-------------------------------------------------
C9SZ-6A312-A .. Single Sheave 'Accessory' Outer Pulley-6" O/A diameter-Bolts to harmonic balancer to add P/S or A/C or smog pump.

Applications: 1968/69 Galaxie/LTD/Thunderbird 429.

* Marked with ID number on the side of balancer. Verify that this is a 1968/69 balancer by either of these numbers. 1970/72 429 uses a different balancer.

I found that the crank is an Eagle brand from Summithttps://www.summitracing.com/parts/esp-104603850. All of their listing for Eagle are internally balanced.
