The hub is meant to be re-used. It's been a while, but I don't remember it being super hard to put the new bearing on. I'm pretty sure it is a slip fit, not pressed (though it will probably take heat/force/lube to get the old one off).

from Jim:
Ok, here's the deal: The Downey 4 speed bellhousing uses a stock 4 speed throw out bearing , shift fork, and the stock shift fork pivot ball. The flywheel will be for an 11" pressure plate, will have 168 teeth, and center hole will be 2 1/2" diameter if your engine is 1985-older, or 2 1/8" diameter if your engine is 1986-newer, and I'm assuming you do not have the newer LS-1 engine. The clutch choice is the issue. A stock Chevy clutch takes more travel to disengage than your Toyota hydraulics produces. For that reason Downey produced a Chevota clutch that is machined to require less travel to disengage. My Chevota pressure plate and disc cost $252.00 plus postage. The guys who try to run a stock Chevy clutch must adjust the throw out bearing so that it is always riding on the pressure plate fingers in order to get full disengagement, but then this is what burns out the bearings (i.e. yours). These then are the same guys who tell you a stock Chevy clutch works.

there should be 2 pix of it from last night. i can take a couple more this afternoon....
Depending on which side of the engine the dipstick is on, that'll tell you whether it's the older or newer SBC configuration. Unfortunately, it's been so long since I've fooled with small blocks, I can't remember now which is which.
A vice, bfh, and appropriate socket will separate those. Maybe squirt some penetrating oil and let it soak for a bit first.
That technique is for removing the pilot bushing from the end of the crankshaft. Grease works too.

It's greased up. Will try and remove this afternoon. Put engine on stand last night. I need to clean the back side up and then I'll start getting it polished.
Thanks guys.

@dnp the dipstick is on he driver's side.
Joseph and crossed some numbers on the heads and block. The only 2 years they cross are 1979. So I guess for now, I'll assume that's the year.

Took intake et al off. Just to inspect and put in new gaskets and seals everywhere-on a hunch....many of the intake and exhaust bolts were barely finger-tight.....most leaked in a spots here and there from the pressure washing.......
Roller rockers.
Lots of cruddy coolant passage build up.
Otherwise. It looked pretty good inside. However. You can see the gray liquid in there. Water. From pressure washing. Probably not enough to hurt it. But I'm glad I took it all down.

Casting numbers for anyone who wants to cross reference as well. We came up with 1979. Only year where the 2 numbers on casting production dates crossed.
Block casting number 3970010
Casting on heads. 462624

Meanwhile. New seals all around engine and it's almost ready to go in. Waiting on a few small parts.
Found a bunch of old rtv and cork gasket in the oil pick up screen area last night. WTF.

So. Is this a Toyota oil pressure sensor or a gM? All of the ones I'm seeing have a male spade on it. One also had the button tab and a spade. I'm assuming one is for a light too on the ones I've been seeing.
