Here is a picture of the 166 frame

[Kapt. Q]

Ok, the counter bores in the flange are for rubber inserts that are part of the sealing gasket that, I think, may actually allow tiny movement , I'm not sure on this, I suppose that might relieves stress, takes some impact forces out. If you look at the above photo you will see two little holes for locating pins in the mating flange.
As for the 'thats why they made so few', nonsense, they made over 15,000 166's, the most mass produced amphibious car to date! They produced a few hundred of the 87/7's, production being limited due to time and materials I think.
I don't think there was any revision in this casting since the 128/166's introduction so I doubt there was any weakness, my casting has a 41 part#, not the date of manufacture, but design date, It is an original not a reproduction, not sure you can get a reproduction of the main part the differential goes in, you can get one of the front cover that connects to the axle beams, the part you can see with the six bolt heads in.
Don't forget that the suspension absorbs many loads, forces (whatever) before they ever get transmitted to the diff casing, etc.
The casing is iron/steel? and about 17kg, that's with out the side covers, another fair few kilo's there too.
OUB, you are right this is a 166 casing, in what ways are the 87/7 casing different? I know the speedometer cable comes out at 90 degrees instead of 180 but was unaware of any other difference, it would be intresting to know. The differences in the transfer box are very apparent in your photo's and I was unaware of them. How did you get the information and parts to make your 87/7 replica?

On the grey museum car you see a reinforcement on the underside of the floorpan. I think the setup is strong enough for the frontdiff. The house is bolted to the frame....On a normal beetle the head is welded on the tunnel. Not that big difference to me. The bolt holes are probably welded tubes trough the Napoleon hat on the frame.

Kapt , Is that a new cast front house?

Great pics!

I find it even more curious that there doesn't seem to be anything to support the shear force along the face of the flange. Unless the bolt bore clearances are very tight, the diff would want to slip upward on the flange when the beam is loaded. I don't think I see any kind of lip on the tunnel flange to support this.

what material was used to cast the front diff and frame head? is it cast iron? steel? aluminum alloy? an approximative weight in kg?

thanks

Because I don't know English plus use translator, so I think, that the symposium is about it whether is tunnel in front enough reinforced. I'm not sure, whether is that a rather reinforced but because these rolling stock be not doing in series so it is possible, that the in using come to some problems. It will catch sight of.
Photograph fore final drive housing are nice to, but this final drive housing is from type 166. Don't belong to on type 877. I I have on photographs this final drive housing, but this to the wagon will not come. Shall I original that the there belongs to.

Heres my diff casing in the raw, it's very strong and heavy, what you see here is two pieces and you can clearly see how it attatches to the front beams/torsion tubes.

I doubt its weak where it attatches to the body because as you can see there are many bolts that attatch it the body and that area is reinforced and it is also attatched to the body via the front beams.

Okay, torque is a measurement so that equation wasn't trying to teach a physics lesson. And weight at ( a certain moment) in motion around an axis would have been a better way for me to put it in laymans.
But where is your axis ?
