BMW marine diesel



" my name is cindy douglas, do

" my name is cindy douglas, douglas machine in slidell louisiana. a customer brought me a cylinder head off of a 1969 Pearson Titon Sailboat. the motor is a BMW marine diesel single cylinder. the casting number on the head is very hard to read but think it is D12 1932600S9U (the 6 & 9 could be 8). Number on the plate of the motor is 59108001594. the exhaust valve has a part number on it T-T 4408, the intake valve has a part number T-T 4438. What we need to know is can this head be milled, and how much, and valve recession spec, spring specs, valve lash, and torque specs. And we need to know if you have parts (gaskets, orings, rings for the piston, etc). also the exhaust valve is destroyed, we need one of them to, please let me know. thanks cindy "

" Folks:

My name is Doc Lamkin, I am an old Medic/Ranger. Right now, I am trying to help out a buddy. He is totally disabled. He loves boating . But, right now, his engine is down. It is a BMW clone, apparently farmed out to another company, but with a BMW logo on the side. It is a single sylender, water cooled, deisel engline, about 5 or six horse. I know how to do the work, but I need the specs. Please help me find the appropriate manual.

Thanks in advance.

"Hello to all of my fellow BMW

"Hello to all of my fellow BMW marine engine lovers. I am in the process of rebuilding a D-50. I found V-12 Engineering to be an invaluable source for parts, and there is a German company listed:


that supplies entire parts lists in PDF form right from their website. This is an incredible resource as the blow-up diagrams are very clear and OEM parts numbers are given for clear identification. They have a darn neaR COMPLETE stock of parts for the BM marine units as well.

For restorations, burned valves, pitted seats, cracked heads, rusted water jackets etc, THE shop is in Farmingdale, NY specializing in the ressurection of old & obscure marine engines. They can do just about anything with an engine. The company is Superweld, 111 Gaza Blvd, Farmingdale, NY and the manager's name is Roy. I recommend them highly. I was a longshorman working as a splicer for Moran Towing in NY harbor and shuttled many large diesel locomotive parts back and forth to Roy for refurbishment.

One interesting point I would like to add, Roy has been running this shop for 25 years and commented that the BMW marine engine is a "100 year design" meaning, if properly maintained and correctly laid up when out of service, these engines will indeed last a lifetime. Love your BMW Marine Diesel, and you will be richly rewarded.Please write, and feel free to exchange ideas.
