I have a China Diesel 3KW, that has 50K hours on it. It is down for
rebuild now, and parts are not the easiest to match up. It seems
every little OEM in china, uses the same basic German Benz design,
but also uses what ever the cheapiest bearings of close to the right
size that is around and adjust the castings to match for each run
of engines. So nothing is standard, and you must actually measure
the bearing sizes when rebuilding these little engines. Mine
has different front and rear Main Bearings as well as different
camshaft bearings than any of the other chinas that I have worked
on. They are a fair engine and will run forever if you keep the
BaseOil clean, but when it come to rebuild time, best be prepared for a
bit of hassel getting the correct parts ordered up.
