Engine Building: Crankshaft Installation, How To
In this video I show you how to install a crankshaft in a small block Chevy. The basics are the same for all engines. This is a 1968 327 block with large mains. This motor will be for sell shortly.

If I heard you correctly you said you put the plastigage on the bearings in the block? Thats not correct,when you put the crank in it'll flatten the plastigage giving a false reading. The crank needs to be laying in the block and the plastigage placed on top of the journal,then the cap installed and torqued. this gives you the actual clearance. Same with the rods,they need to be up tight to the journal and the cap torqued down to get the actual clearance.

Do I have to use my stock windage tray or can I eliminate it and replace the longer bolts for it with bolts like the others so they are like this 1

a windage tray is absolutely a benefit,it allows the oil to not rob horsepower by staying in the pan and not being slung around the engine.

Hey man im 17 rebuilding my first d15b6 honda engine and im using a really shitty torque wrench that doesnt click its like a needle and I dont feel its accurate. When I do my second pass of 40lbs my crank locks up. I loosened it up and tried again and it didnt lock up but it wasnt as smooth as my 20lb pass. Should I get a new torque wrench or is there something wrong with my crank?

Should have shown in great detail with close up's of how to get real main seal on rear cap to line up with lower half in block and where ( are not ) to put RTV around rear main cap as seal or block register to get solid sealing. This question is what I was looking to find out if I clock the rear seal .

@@ZaksMuscleMotors You did on the block side yes , but nothing on the cap side as you just put it on not showing where you put any sealer on the cap side or how the cap slips into the groove of the block . Many are saying when they put the cap on it pushes the seal back to none clocked position level with the block . That is what is still unclear no matter how many times I watch it . .

Mine spins freely by hand but doesn't spin like yours in the end, should it spin like that? My clearances were between .0015-.002-Mines a 95 1pc seal if that makes a difference

James I’m sorry I didn’t see this sooner. I’m sure it’s too late now, but it’s ok as long as you have at least 1.5 thou clearance and it spins free, doesn’t have to spin forever. The one in the camaro doesn’t spin like this one either

@@ZaksMuscleMotors I Actually found the bolt sir. But I have one more question . I did everything you did step by step on the video. And it’s a brand new crankshaft ( not remanufactured) and brand new bearing (stock ) and it spends nice . But not like with a little twirl. Like if I put a towel and I vice grip on the thought I can move it with my pinkie. I used Assembly lube and torqued all the bolts down . Do u think it just needs time to break in

@@ZaksMuscleMotors hey Zach is it possible for me to drop the crankshaft with the engine in the car from underneath I already have the head off to vehicle and I took the piston in the connecting rods out because I needed new rod bearings but since I'm doing the rod bearing shouldn't I do the main bearings as well so I was thinking can I pull that crankshaft through the bottom if I make sure I do it very carefully and safely

Why can’t you touch the surface of the bearings with your bare hand? I’m a car noob and I’m barely learning.

@ZaksMuscleMotors 3 жыл бұрын
People do and 99% of them won’t have issues. But I try my best to keep all the oils from my hands off of them because the oils from your body are acidic and if left to sit on the bearing surface can cause pitting dry spots on the bearings and maybe pitting over time.

You may not have seen it cause it didn’t stick out much. When I set it, it moved where it needed to be. I can assure you it is there, this motor still runs today. Which would be very unlikely if that rear seal was missing. That would be a rather noticeable leak.
