Hi,

go surfing on this site, the DLM is a workshop, building new stam locomotives and restoring old ones. And they also developed and built the new steam engine of the Lake geneva paddler Montreux in 2000, which got this new engine when they gave the diesel electric engine to the waste. I think, that was the right way instead of doing reverse. But that´s possible  only in the lucky Switzerland!

kind regards

Andy

Hi PD's & thanks Andy for the build snaps of the replacement Montreux steam engine

In snaps 17, 18 & 20.....we see a GRAY coloured device on the output shaft [right hand side in each view]...possibly 1.5 m diameter & 2.0 m tall

Is this part of the engine?  ......it appears to have it's own lubrication tubing mounted??....or could be an external brake unit for load testing the engine?....................Derek

Hi Derek,

if you could understand German, it was written in the several links of the report. This part is, as you supposed, a brake for testing the output of the engine. This had to be checked before the CGN paid the engine. What was this brake? Was the former transmission unit of the ship which had to work against the new engine! Torque of the engine was sufficient!

I use Google Translate, and it works pretty well. I would love to be able to play with the Machining Center they used.

OK PD's....

Gerald ....yes I do use Google translate......

Andy.....I have looked @ the DS  revaporisiterte Montreux    Foto 024 ....shaft couplings....but do not understand the locking external tubes on each end of each coupling bolt??.............Derek

Derek,
 I cannot see what you mean? maybe too many smileys around the photo?

Hello Andy,

Derek is refering to the flange where the crankshaft and the paddlewheel shaft meet. The six visible bolts per side (obviously there are more per side) seem to have an unusual bolt or nut that extends several inches from the flange on the paddlewheel side of the flange. You can see them clearer in the original photo on the website of the photo above, photo #24.

Hi PD's &  Randy for the explanation......... ....I was deliberating in asking the question again as the more I looked @ foto 24....the less unsure I was........as the outboard tube caps appear to be on a larger PCD than the corresponding inboard bolt heads ...but this could be an optical illusion

If we can see six coupling bolts....my guess is a total of ten on each side

Foto 14 also displays a similar bolted arrangement between the three bigend support columns & the fabricated engine bed........Derek

Hi PD's....in the Montreux preamble for the new engine...the following is noted.....

Design and construction .......Klassische, geschmiedete Kurbelwelle -- Classic, forged crankshaft

Interestingly in one of the  video 200 80419_036 [provided by Andy]....the RH crank webs appear to be of different [fabricated?] construction and machined differently to the  LH crank webs

 ......I use RH & LH as shown on the screen in the video as I do not know the orientation of the engine in the vessel

Anyway.....great videos & thanks Andy............assumed as another vessel in video 20080522_0160...we see the three engine pressure gauges & two are confirming the subtle pressure pulstaions of the engine....not sure if the center gauge is  ...or could it be a condensor vacuum gauge?........Derek

Hi Derek,

I cannot find this video- number!?

But I only have videos of the HOHENTWIEL- engine and of the URI engine. HOHENTWIEL is black painted, Uri red painted. Both are fitted in front of the paddle shaft, both are ESCHER WYSS engines.
The video with these gauges is from HOHENTWIEL. according th what the macne officer told me this are the pumps for the toilet water and behind the big one moving excenter is the vaccum pump- like shown to you in the photo of my model of the DIESSEN.

Andy,

Let me once again translate for Derek

Derek is referring to video 200 80419-0386. It shows the 2 crankshaft webs/throws in action. While the crank on the left in the video appears to be forged from a solid piece, the one on the right looks as if the crank pin/journal might be removable via the large nut on the left side of the pin. Do you know of the reason for such construction? Why the difference between the 2 pins? Repairs perhaps?

Hi,

I think, that tue crankshaft is divided with the bolt of the right pin, because there is a second piece with annother pin for moving the vaccum pump which cannot be seen on the right side. Was too long to produce??
