Tores mailbox VIIC and VIIC/41 operation and technical details

The other day when updating the Camshaft covers I had to used the side view to make sure I had the correct alignment. So I update a little more of my side view

Simon.
Very good, but don`t forget  foldable step along the engine.

Simon.
Of course I don`t remember but according to a photo of U 178   the nuts  were out. See picture below.

New Camshaft  covers, The old covers can be seen in the post above.

Simon
Beautiful Xmas decoration.   Have you noticed that only the centercover has 3 nuts whereas the 2 others have 4 ? I guess you had the correct configuration on the old drawing.
Tore

Thanks, Tore. I did not noted the number of nuts. Fixes now.

Hi Simon.
It seems to be very good. Seeing the hatch I just came to remember an intricate system of rods connecting the steelhatches to the wooden deck hatches so they could be opened in one operation. Anyhow this system was used for the galley hatch and fwd torpedo loadinghatch which were crewaccesses while alongside. Pictures below, on one of the photos you can see a guy operating one of the external valves from the deck by the T bar.
Tore

Thanks for the pictures and information.

Tore, a while ago we had a discuss about fuel filter and which one was a original fuel German filter.
 
Would you go for port or starboard?

Simon.
I would go for port, but that`s pure guesswork from my side.
Tore

Found evidence that the post side fuel filters are very likely the original German filters

Hi Tore

I was able to follow the FO drain line (below and orange), however, this is different than that you posted I am following the worng line



Simon

Simon.
It might be two drainpipes to the draintank, fwd and aft. I don`t have a proper photo to ascertain the lay out.
Tore

Tore, there seem to be two styles of funnels, it may possibly suggest alteration to this line.

Also check my pictures and found a photo that very strong suggest that this line is collected at both the aft and stern.

Do you think both drain lines are original German, if I had to choose one drain line I would think that the forward line this the original German line.

[tore]

Simon
Hard to say, but I should say it is original. If you have a closer look you may see the line has its highest point in the middle of the engine , where the two cyliderblocks are flanged together. From this point the forward half of the pipe inclines down forward and the other down  aft.

35 years of my life I have been working with this kind of engines. They are massive. Cylinder bore of almost 1000mm and stroke of 1800mm, a grown up man could easely stand within the cylinder .

Nice to have confirmation my guesswork was right.

Lubricating oil collecting and distributing manifold

Tore, how does this work, If you open the valve with the handle, its open and closes both valves at the same time??

Looks great! We did not get any snow for Christmas, we got +25

Luboil returnpipe.
This valvechest is selecting which the luboil returntank is connected the engine. If you shut one valve the other opens, thus you have always a drain connection in the system.

We have rigth now -9 degrees C and just got 30 cm fresh snow during the nigth and pitch dark at 9 oclock a.m, if you miss the snow just come over. 5 days ago 3 passengertrains  were stuck in the snow for hours and we have already had the first avalanche killing people.

Thanks, Tore. I will update my drawing tomorrow. I have to update these pipes so I can correctly lay down the FO drain lines.
