Default Otto & Langen

We are doing a cosmetic restoration on our Otto & Langen at Rough and Tumble. I thought that people would like to see the engine taken to pieces.

Keven's right. Paint it Allis Chalmers orange!..........

Great to see the photos of the engine in pieces. Take plenty of photos, then take some more.

Thanks for sharing.

How about red white and blue like a lot of engines restored in the 1970's. Actually we are going with brown to match Greg Johnson's 2 HP Deutz slide valve engine. We are also going to use linseed oil based paint which is what it would have had on it originally.

Bill, is this the first time the OL has been fully disassembled since John Wilcox reworked it in Willock's shop in the 70's?

Thanks for posting these photos Bill.

Interesting to see that the water jacket plate on the underneath of the engine bolts to the cylinder head with a single fastener. This is the same as the later engines.

The fluted column in the Powerhouse Museum in Australia - its water jacket plate is held on with a number of bolts running in a circular pattern.

Regards,
Wayne

Any thoughts of straightening the flywheel shaft to take that nasty wobble out?

Tommy,
Yes this is the first time it has been apart since it was painted, I believe it was around 1978.

Brian, Yes we are going to straighten the main shaft.

Bill, should there be any leftover parts after reassembly, here are the operating instructions (as well as sales brochure) for the Deutz atmospheric engine. Should you need these documents send me a mail.

We got a donation of a new sub base casting that was patterned off of serial number 1 O&L at the Deutz Museum. I mounted it to the face plate on my milling machine and faced it top and bottom and drilled the engine mounting holes.

I made some more progress on the O&L. I got the main shaft much straighter than it was. It had a total runout of .110" and I got it down to only .010" total runout. The flywheel should run a lot truer now. I did have to heat the shaft some as my little 12 ton press could not bend the shaft cold.

Thanks to Wayne Grenning, we now know the full history of the engine from day one. Wayne has a contact that knows a retired corporate historian of the Deutz company and from him we have learned that engine number 10, which is our engine, was shipped from the factory on February 15th 1868 to John A Roebling. From Roebling it went to the Stevens institute in 1873. William Willock bought the engine from Stevens in 1953 and it was then donated to Rough and Tumble upon Willock's death.

I got some more work done on the Otto & Langen. I first scraped one side of the slide valve flat and then machined off a few thousandths off as the slide was tapered by about .005" then I scraped the other side flat and then re scraped the first side because when I machined the surface the first side curved down. Then I scraped the cover of the exhaust slide.
