Case split, just get get it fully apart, what am I missing?

[lakedawgs]

1600 single port on my '66 Squareback.
I have split the case with no problem but cannot pull the half case apart. It slides up about 1+ inch and stops. Feels like something in the upper part of the case is stopping it.

Feel stupid, sure I am missing something basic but cannot figure out what it is. And yes, ALL nuts and bolts are out.
Thanks

Thinking I might know what I did wrong but not sure how to fix it.
When trying to separate the case halves I let the lifters fall from the top half. I have since flipped the motor and to other side lifters have fallen into the motor case. I'm guessing this might be my problem in separating the halves now. Did not thing letting them fall was a big deal, but now I am regretting that decision.

[lakedawgs]

OK, case is now about 2.5" apart and all lifters are out, still cannot separate. Something is forcably blocking and I don't want to push things.
Need to stop and do some research, I am missing something and Bentley has been no help so far.
Time to start over in my reading.

if it's literally separated 2 plus inches,it's probably hanging on the case studs.Grab it by the head studs on either side a give 'er.

[lakedawgs]

I have done that, but not with too much force, something is holding on.
Stupid question, on my part, does the flywheel have to be removed to split the case?

Depending on what tools you have,it's easier to take off when the crank is in the case.

I thought about that but have a full shop at my disposal where I work, so I just figured I would split the case with the flywheel attached. From research it should not matter.

It doesn't matter with regards to your problem.You can take it off with an air impact gun & 36mm socket later.It's not keeping your case halves together.I say it's binding on the main case studs (the 12mm ones).
I assume that when you try to separate the halves that the crank is staying in one half or the other,and not staying in one half on one end & the other half on the other end?

[lakedawgs]

The crank is loose from the halves. I have is supported on wood as not to bind. It is loose from the bearings for sure. As right now the motor is laying horizontal. I have placed it vertical, on both ends, with no difference.

As noted if you have it that far apart it is simply catching on the threads.
Rubba mallet give it a good back and forth and assist while pullling, but you are correct not to want to force it.
It shouldn't require much force unless there is a wad of sealant on the case studs or something.

Note that while you can split a case on a T1 with the FW attached,
on a T4 there is a stud/nut that lives there, so FW must come off on a T4.

Not relevant to lakedawg's predicament, but it seems a good place to mention that it's also true of pre-40HP engines - they have a couple of bolts/nuts behind the flywheel too.

You removed the pistons right?

[Piledriver]

Nice, haven't seen Okrasa heads in ages.

What coating on the case in that pic, spraybomb or something more interesting?
Looks good.

Not my motor (I wish) I didn't see anything mentioned in the build thread, but he didn't spare the powder-coating and clear cad-plating elsewhere ... http://www.thesamba.com/vw/forum/viewto ... ?p=6765890

Since lakedawgs said he was using a Bentley manual, I suppose we've all assumed that to be true...but it's a good question, perhaps he skipped some pages

[lakedawgs]

Yes, barrels are removed, not pistons. Just about everything is off the motor; breather, fuel pump, distributor, etc. Crank and cam are now loose. I am going to get it back on my bench tonight and go over the studs to make sure nothing is hold me up.
