+Somewhere around twenty years ago, when I was still a small child, I got a [Wilesco D305 steam fire engine](https://www.wilesco-shop.de/mobile-dampfmaschinen/dampf-feuerwehrauto-d305.html) for christmas.
+It's now finally back in my possession, so of course I had to try it out.
+My friend Igor and his daugther volunteered to help 🚂

+Unfortunately it didn't work too well.
+We got it to actually drive for about 30sec, but that was pretty much the best we could make it do.

+
+I think it's a combination of negative factors:
+
+* The main shaft of the flywheel is slightly bent, causing increased resistance to turning as well as misalignment of gears.
+* The piston and cylinder are not moving totally freely, even after oiling everything.
+* The main valve is leaking and very wobbly.
+* The safety valve o-ring is worn out and loose.
+* The whistle is leaking.
+* The whole kettle is full of scale and probably oxidized.
+Lots of green-white slug came out of the outlet pipe at first.
+* The fuel is probably not new and may have sucked in some moisture from the air, reducing the intensity of the fire.
+* A part of the chimney is missing.
+Maybe this results in insuficcient airflow to the fire?
+The fire seemed too weak after inserting it below the kettle, burning more intensely outside the firebox.
+* Maybe the soot from past firings on the kettle is reducing thermal conduction?
+* The gears are not properly touching when trying to drive the pump.
+* The pump is leaking and does not produce any pressure or flow.
+
+So not much steam is produced in the first place.
+Then some of it is lost in the leaking valves.
+And finally the machine itself is hard to move.
+So even with the most intense fire we managed to create there's really not much pressure / steam produced.
+And even in the short time where the whistle sounded like there was good pressure, it still was not enough to run it properly.

+
+Fortunately Wilesco still exists.
+And as you would expect from a small and old company like this, they also have a [big set of replacement parts](https://www.wilesco-shop.de/search?search=d305).
+Also my grandfather was actually a "licensed" Wilesco repairman and seller.
+So he had quite a big collection of their machines, toys and replacement parts.
+Some replacement parts actually were part of the things I managed to get from the house last month.

+
+I have a bunch of generic parts like gaskets, but unfortunately no complete safety valve with a matching thread.
+And also I don't yet have the required brazing/soldering skills to do work like replacing the main valve.
+So I'm not quite sure how to proceed with this at the moment.
+For now it will have to go to the healing bench.
