rebuilding a 289 - what is this part?

[mb_stangz]

I am rebuilding a 289 from my 65 fastback and I have a part I can not remember what it is.
It seems to fit the crankshaft.
It is a thin metal round plate recessed and has a notch to fit the crangshaft key. Seems to fit around the harmonic balancer. Does this part go after the crank gear before the timing cover is on or with the harmonic balancer?
I'm sure I will figure this out, but i wanted to see if anyone else used this on their rebuild or know what its purpose is?
See picture.

goes on the crank. After the timing chain, inside the timing chain cover. So before the harmonic balancer.

it is called an oil slinger. its purpose is to help prevent oil leaks by slinging oil away from the front seal.

THANKS FOLK!

Commonly called an "Oil Slinger". Helps to keep
oil off the damper seal, and prevent leaks. New
engines don't have it. Most people trash theirs during
a rebuild.

You could probably get one at the dealer.

The trick to preventing a leak there is to install
the front cover so it's square to the crank snout and
not the block.
Install the gaskets, and the bolts hand tight.
Slid the damper on so the hub just barely enters the
seal. Move thr front cover around until you have even
seal compression around the circumfrence.

head gaskets

I have another question. I just opened my head gaskets and they both
are exactly the same and they both have "front" labeled on them. In
order for them both to face the front on each side of the motor, I
would have to flip one, also is it normal to block
the front water passages on these gaskets? Do rebuilders drill extra
water passage holes in the gasket to fit the the heads and motor to
match?

yes water holes in rear, it dosn't matter what side is up it there is no left and right on most gaskets. having the front blocked is MANDATORY. if the rear was blocked and the front open water would flow in then straight up and out the thermostat and not through the engine. you would cool the front of #1 and #5 and nothing else.

Install with the word front toward the front. Yes, one side will have the writing facing down--that is correct.

The front holes are blocked on both sides. Do not mod the gasket as you might ruin the flow through the heads. The coolant enters the heads from the rear of the block, travels forward, exits through the intake manifold and then into the radiator.

I figured that what I was reading everyone does. Thanks GuYS!
