Has anyone found a good reference to cross reference these things? I've got a m4-30 (for the time being) and it seems like something that people keep talking about, but the GOOGLE can't seem to find it.
pm sent...power for sale,
i have an m4-30 universal engine made by kubota for westerbeke. The engine model # located under the injector pump is v850-176248 and the serial #08510. I need 4 injectors. The current injectors are nissan denso 3340 7j and according to westerbeke part #302735. Can you help?
I believe (90% sure) that all of these engines use the same injectors... My earlier post referenced an injector that cross references to Kubota Part Numbers; 15221-53000, 15271-53002, 19202-53020, 19202-53021, 70000-65208There used to be a document titled History of the Universal Motor Company in numerous places on the web... It seems to have been deleted from most locations (I wonder why).
Here are the salient points:

It was similar to its namesake, since it was a 4 cylinder model weighing slightly less (122 kg / 270 lb as opposed to the original's 150 kg / 330 lb with reduction drive - the M4-30 was only offered with a reduction drive) and generating slightly less power (18.6 kW / 25 hp at 3,600 rpm as opposed to the original's 22 kW / 30 hp at 3,500 rpm) with a smaller displacement (850 cc / 52 cu in as opposed to the original's 1,065 cc / 65 cu in).
