Main bearing cap removal

[ford20]

Are the main caps still held on by jackscrews like they are with the 3V? I took out one of the side bolts real quick and shined a light down there to see if i could figure it out but I'm not certain. If they are does anyone know what size Allen Wrench to use to relax them?

Anyone? I know people have taken these blocks apart before.

To be honest, it maybe that no one knows what the hell your talking about. Just a guess...

I'll take a stab at this starting with the basics. Each cap has 6 fasteners. The 'side bolt' you took out reveals no picture of what the other fasteners look like or what they are. Having looked in my manual, the inner main cap fasteners have two 'bolts' and two nut/stud combos on each cap. There is no indication that any of them have an allen screw insert.

Yes, that could very well be the case. It is a 6 bolt main, 4 top bolts and the 2 side bolts.

I can see what the manual says but I am almost positive there are jack screws on the 4.6L 3V that are located behind the side bolts. You loosen those up and they release tension on the main caps and you can now take them out (the workshop manifold doesn't say anything about them either).

Now I am wondering if that is the case with the 5.0 block as well and if not how do you remove them?

There is no mention of SET SCREWS or, in your vernacular, jack screws that have to be removed. Even the figures show none.

No jack screws on the 4.6 3V or the Coyote 5L.

You just need to wiggle them out with channel locks; be careful. Pull up and wiggle on one side then alternate until it's mostly free, then pull it free.
