crankshaft removal
Hey guys, so I need a new crankshaft. How can I take it out without going through the top, like can I go through the bottom end by taking of the clutch and harmonic balancer. Any how to links would be great.
Thanks
Thanks

yeah I rebuilt my engine a while ago, There is some scoring on cylinder two that is making the bearing slip, causing the rod to have some play. I think I know what I'm doing when it comes to engines. I just need a simple link to find out how to drop the crank.

You might as well pull the engine. I'm assuming your pulling the rods and pistons since atleast one rod will probably need replaced if it spun. You'll have to take the head off to put the rods/ pistons back in so you might as well take it all out.

well, the rod isn't in bad shape, like there is no color change from heat or anything, just the bearings aren't seating right on the crank. But there is no way to take it out from the bottom, by taking out the clutch and harmonic balancer?

How do you plan on removing the rods and pistons and then putting them back again without raking off the head? Honestly the $50 for a head gasket is well worth it to avoid whatever hassle you are gonna create by leaving the head on.

In theory you could just pull the oil pan and lower block half to remove the crank. I really wouldn't want to do that in the air though, one slip or knick on the crank/bearings and you are doing more damage than you are trying to fix.
You'd still have to remove the transmission, all timing gear and everything on the lower half of the engine to split the block. Just pull the whole thing out (engine/trans) as a unit, split them on the ground, put the block upside down on an engine stand. Then you can pull everything down and I guess leave the pistons where they are and assume nothing it going to move? Seems like a ton of work to avoid pulling the head.

yeah, that's what I was afraid of. Guess I'm pulling the head. Thanks guys for the input, but one more question. I will still need to take the clutch and flywheel off right? so it would be worth it to upgrade the clutch at this point

Flywheel comes off the crank if you need a new one, I spent the past 3 month fighting a tough build and I'll chip in my hard won experience: pull the block, easier that it looks and I say this as a guy who went through 4! head gaskets before chucking the block, crank and all. Cutting corners on an ecotec is giving trouble the middle finger.

haha I here ya man, I find these engines are a lot easier then most to work on. But unfortunately I don't have a picker to pull the engine out as one. I don't mind taking it apart though

This is a good option and just unbolt the DP from the catback and reinstillation is a breeze.

So leaving the head and block in while removing the subframe, oil pan, transmission, lower crank case, wiring harness(removing it from the block not the car), and two of the 4 mounts is easier than just removing the mounts, wiring harness(once again off the block), exhast mani, and lifting it out? OK...
This is a good option and just unbolt the DP from the catback and reinstillation is a breeze.
