Found this to post I have used them with great success Through the MTOA we have discovered the person who designed the diesel engine used in most all trawlers for most of the 1960s thru the 1980s ( Lehman Diesel 120, 135 and 165). This person (Bob Smith) now has his own company and still builds and supplies parts for the Lehman Diesels. Many people are not aware of this and often have a difficult time finding the parts they need. Bob not only can get any part needed for us (used, new, or "redesigned and improved") but he will spend all the time needed on the phone to diagnose and suggest a fix for any problem as "he is the one who designed the engine, wrote the Users Manual, and made up all the part numbers". Bob's address is: American Diesel Corp. Hillcrest Heights (Rt. 3 North) P.O.Box 1838 Kilmarnock, VA. 22482 Phone: 804-435-3107 FAX: 804-435-6420 Take Yahoo! Mail with you!
