Crankshaft problem.

[stutz43078]

Alrighty boys. This is probably going to lose me a lot of respect, but I need to know. I'm rebuilding the engine on my 91 gst without pulling it. I've built 3 or 4 engines now in classes but they were already pulled from the car. I went to drop the crankshaft out of the bottom and realized that it still seems to be attached to the transmission in some way. I'm curious if I need to pull the trainy or if there is a trick to doing this. If you could guys could give me some insight that would be great. Thanks.

Yes. If you are pulling the crank then the engine needs to come out. The crank is bolted to the flywheel, which is bolted to a clutch or torque converted (dependent on auto or manual).

So yes you have to pull the engine or tranny.

Sweet! Was trying to avoid having to find a cherry picker, but if it needs done, it needs done.

You can drop the tranny and avoid finding a jerry picker.

Well found a friend that's letting me use his jerry picker this upcoming monday. I was looking today though, is it even possible to pull the engine without the tranny? That's what I prefer to do, since all the engine is right now is a block and a crankshaft. My suspension is untouched and I don't want to remove the axles, but it doesn't look like there is enough clearance to pull the engine away from the tranny in the engine bay. Is there a trick to it? I'm trying to get the details before I do it haha. Thanks alot.

It's kind of hard to do without pulling the tranny as well. I don't know about the FWD cars but the AWD has the driver side axle mounted to the back of the block. May cause an issue if the FWD is the same way.

just wondering how do u plan on having the block machined if it stays in the car?

Well, I went out and look. The 2wd model doesn't have anything connecting the axle to the engine. I just looked it up in my haynes manual that all I'll have to disconnect on my suspension/brakes is the steering knuckle to remove the axles. I just dont see there being enough room in the bay to seperate the engine and tranny without removing it. So I guess that's the new game plan haha.

To be honest, don't plan on machining it. Everything looks good, I kind of regret starting the whole process to begin with. But I have the parts now so might as well do it. I mean the intake cam had two lobs that looked scorched but the journals and valve train looked like they had less than 50k on them. The car itself has nearly 150k. The cylinders, you could still see the honing marks. Then what I have seen so far of the crank and connecting rod journals, they are flawless. I don't plan on putting this car through a total beating like some dsm boys do, so if I go ahead and do the bearing now, I expect this car to last with the 15 psi I plan to be running. The only thing I could tell was bad were the valve caps, could definately tell from the vavles and cylinders that it was burning oil.

Why not just drop it out of the bottom of the car on a jack, it is much easier.

Is it? I really wouldn't know haha. I've helped pull a few 350's, but those were cake with a picker. The only problem I see there, is how do you get the body over the engine and tranny once you drop it?

i dont see how using a jack to drop an engine be easier than lifting it up with a hoist. u can rent one for a day pretty cheap. lift ## tranny and block and save urself a headache. and when u put it back in is way easier.

I believe he was saying to drop the tranny on a jack. At least I hope that is what he meant.

pulling a FWD motor isn't too bad without pulling the tranny, just go from the bottom to unbolt the torque convertor/flywheel, removed the driver side motor mount completely,(and possibly belts/pulleys) and when lifting the motor, use a long bar to wedge the motor away from the trans a bit, oh and it also helps to jack the trans up a little bit to get it on an angle, hope this helps a little
