Default Clark MD-6

I just thought I'd contribute this photo of a Clark Bro's MD-6 Marine Diesel that came out of one of my family's tugboats back in the early 80's and is still in front of the building at the family marina in Pensacola.

It came out of a US Army 86' ST tug built in 1944 that we repowered in 1984 with a Caterpillar 3512.

My grandfather set this engine up to run where it sits, but it was only cranked at it's current location once.

I'm curious if anyone knows how many of these were built or if there are currently any still in service.

There are three pages in the Diesel Engine Catalog for 1949, the DG-6 is quoted as being 2-cycle, bore 12.5" stroke 16", 300-400rpm operating speed, 60,000# weight.

No mention of the MD-6, it may have been dropped after the war.

Clarke Brothers were based at Olean, New York:

"Clark Bros. Co. came to Olean in 1912 after the destruction of the plant in Belmont, NY. It grew to become one of the largest industries in Olean with the manufacture of compressors. In June of 1937, Clark Bros merged with Dresser Mfg. Co. of Bradford, Pa. Clark Bros is still in operation and also one of the larger manufactories in Olean." From: http://www.northoleanhistory.com/earlyindustryin.html

"This maker was founded in 1880 in Belmont. Their plant burned down in 1912, and they relocated to Olean. From the beginning they made sawmill and agricultural machinery, including steam engines. After World War I the company started making oil-field equipment.

In 1938 the company merged with S. R. Dresser Manufacturing Co. of Bradford, PA. The resulting company, Dresser Clark Co., became Dresser Industries in 1956, although the Dresser-Clark name persisted in informal usage. Dresser Industries merged with Ingersoll-Rand in 1987 to form Dresser-Rand Co., which moved its headquarters to Olean, NY in 2000." From: http://vintagemachinery.org/mfgindex/detail.aspx?id=179

Yes, all that information was on the Dresser-Rand Corporate history page. The marine diesels were made from 1942 through 1946 to fill a war department requirement and all of the engines went in small coastal tankers (YO's) and 86' Army ST tugs, but that's the extent of what I have on them.

Thanks,

The Diesel Engine Catalog of 1943 didn't show the MD-6 but did show a line of 4 stroke engines as well as their 2 stroke ones .
The 1945 catalog yielded the scans I have attached and a little information.
Here 'tis

Thanks Enginenut2. The second page (clarke2.pdf) shows the MD-6 engine and apparently this document is exactly the type of information I was looking for. Again, Thanks!

Smile Re: Clark MD-6

What a coincidence. My name is Dan Friend, and I'm a researcher of US Army tugboats made in DeLand, Florida, and others. I've been promised one of these engines that's in an old WW2 ST: but it's in Stockholm, Sweden. Any guess as to it's weight? It just happens to have been in ST 479, which was at Normandy and was built in DeLand. I'm curious as to what number ST you have as well. I might drive over to Pensacola to see your engine...contact me at dfriend001@cfl.rr.com
