Dave: I'll be very excited to see the machine cleaned up and fired up! I really appreciate that you're spending the time to do the job properly, it's a shame how many machines end up scrapped just because they need a really good going through and having all the neglect un-done!

Here you can see the rags the previous owner stuffed all over the base of the unit to capture all the leaking fluid going everywhere. The fans were caked with gunk and heat exchanger was almost clogged completely closed. The stuff that came out of the rad has varying consistency between clay and molasses and is extremely difficult to work with. It doesn't wipe off surfaces and I'm very thankful for ultrasonic cleaning technology otherwise that would have been very difficult to get as clean as it now is. I can only imagine what the lungs look like of the people that had to work in the shop this machine came from.

Hi i have a dmu50 evo 2000, model in my machine the oil for the 4-5 th axis gets suck from the reservoir to the bottom of the casting to the pump-motor and then goes to the radiator and then to the filter and back to the 4-5 axis where it lubricates everything. the radiator can't stand the pressures and it opens in the solders and leaks. in the newer versions like yours the oil goes first to the radiator and then to the motor, so the heat radiator dosen't see hi pressure. In the old version the exit from the radiator had a tube brazed so the air goes out first and after the oil and the radiator gets filled with oil.
Can you remember how they have constructed the output from the radiator so the air doesn't get traped in the radiator

Looking at a couple 90s model MH600C with the 532 control. Dont know a lot about the 532 but its very interesting to read it uses a VME chassis which Ive always regarded as excellent industrial bus. Ive had a number of VME based unix systems from days past. The bus is slow compared with PCI but for industrial purposes it may be adequate. Very reliable as I remember it.
