Is this the bolt @914werke ?

I had to cut the exhaust off, those exhaust manifold bolts weren’t moving.

Thanks, removed but still not budging.

Found two more bolts - under the push rod tubes. Need to figure out how to remove those now...

The pushrod tubes just twist out I believe.

Check out the goop

If the head are really stuck on in the past I made an spark plug adapter and hooked a hydraulic power pack (tractor, wood splitter, car lift, etc) and it popped the head right off.

Did this on a 36hp engine with fairly high value okrasa heads and it worked good, but it's a bit messy if you miss the waste oil bucket.

Good idea. I like it!

Could the same thing be done with air pressure? 100 psi into two 100mm pistons/head chambers is 2400 lbs of force. Each cylinder contributing ~1200 lbs of force.

Seems like that would be plenty without the need to resort to hydraulics that would increase the force by an order of magnitude (x10) using 1000psi hydrualic pressure. Would be cleaner w/o risk of dumping oil. (IMG:style_emoticons/default/idea.gif)

Superhawk,
I would not use air pressure because the head and cylinder would launch like a cannon when it let go.....unlike hydraulic fluid.

Got 3 of the 4 tubes out, they were really stuck in there.

Once the last one is out I can get to the plate that is blocking access to the remaining two bolts.

Hopefully I’ll have at least one of the cylinders off tomorrow and I will look for markings and take measurements etc. I’m always amazed at how much you guys know about these and related engines

Thanks

@sixnotfour might have it nailed. One of your pictures looks like there is an extra head stud where the Pauter's are.

@914toy - Keith, your seat of the pants feel (as a passenger no less) for how much torque the car had was right.
