Yes, there are many other Lehman experts for sure. They are a very easy engine to work on. Just make sure you get the upgrades AD has developed over the years and they become even easier to maintain.
The reason AD is so popular is because it's founder Bob Smith (deceased), worked with Roger Lehman to create the Lehman Ford. In fact, it was Bob who contacted Ford to get permission to use "Ford" as part of the name. Bob was in charge of US sales and service. Think back when most of the trawlers came from yards all over Taiwan and most of those (3,000) were Marine Traders - all equipped with the Lehman engines. Then CHB, DeFever, and most of the other production builders started using the Lehmans.
Over the years, I've had many conversations with Bob, took the diesel class from him - tore down a 120, popped all the injectors, and rebuilt it. Bob took it outside and we were all pleased and relieved when it fired right up and purred like a kitten - even with two very weak injectors.
Bob was member number 24, and for years wrote the "Engineering Corner" for the MTOA (Marine Trader Owners Association, changed to Marine Trawler Owners Association). So many of the articles were about the Lehman's and the transmissions. Back issues are in the archives for anyone with any questions about these engines.
Brian, like Bob, charged you for the parts and the service work, but gave freely of their time and expertise to all comers and callers. Bob crawled into many an engine room at Trawler Fests and popular trawler rendezvous across the nation to diagnose problems (many he just fixed it on the spot). Oh, and did I say, he was fun too? Now, Art DeFever had a hollow leg, but that's another story (I had the 49' DeFever CPMY).
It's been a while, but I think they still build about 100 new ADs every year. They are a direct replacement for the Lehmans.
