What's the easiest way to get the flywheel and crank bolt off? ALSO, the haynes manual I have says something about marking the flywheel in relation to the crank. If I'm putting it on the new 383 LS1, do I still have to do that? And if so, mark it how? Thanks.

 

Big breaker bar and a 24mm socket for the crank bolt. You'll have to find a way to hold the flexplate stationary because you're going to need to torque the **** outta that crank bolt to get it out. Then use a 3 jaw gear puller to get the crank pulley off.

I have never heard of having to mark the flexplate in relation to the crank, I guess it could be for balancing purposes. But if you're putting it on a new motor the mark won't mean anything anyway.

 

Thanks for the info Thunder!

One problem, I've got the ASP Crank pulley and the 3-arm puller has nothing to hold on to. How do I get this off and back on the new motor safely? I've read of a few people putting the pulley in the oven for like 20 minutes and sliding it over the crank. Is this really safe for the ASP pulley? I don't want to use a longer bolt as I'm scared as hell of stripping the threads on the crank.

As far as holding the flywheel still, do ya'll think a flywheel tool would hold it enough to try and get the bolt off?

 

i used a jack handle stuck through the pulley and pushed up against the block to hold it while i took the belt off, worked pretty good.

 

That would work with the stock pulley, but on the ASP pulley, it is completely solid, no holes.

 

a big impact with lots of air (shop sized tank) will remove the bolt easily, as for the pulley, you can use a power steering pump pulley puller. There is three holes in the face of the pulley, the bolts in the kit will screw in there and away you go - I would suggest getting grade 8 bolts first, the ones that the kit supplies are cheap and I've seen some break already (ask 1BADC10)

 

I think my g/f's dad has a impact wrench. I think what I'm gonna do is put the stock pulley on the stroker for a few weeks, until I can take the 5.3 out to their house. It doesn't need the flywheel on to get the bolt off does it?

Now, to get the stock crank pulley on, will it damage the crank if I put it oven? Any tips to doing this?

 

Nope, just preheat oven to 200*, bake for 20 minutes, remove with gloves, install onto crank snout

 

It won't hurt the front seal on the timing cover either, right?

 

The motor runs at a regulated temp of 210 (195 thermo will run up that high), so .. no, the seal should be fine.
