Andrew's request for assistance...Paul
Hope you can help.
I have a Heinrici motor that was passed down by my father and his father. The motor was used in a mineral water bottling operation that the Alkemade family ran around WW1.
The motor I have is a later model with a 2" bore and central displacer. (see photos).
I am very interested in talking with anyone that has one as mine has a problem which I would dearly like to fix.
As it was missing its original stand it had never been used to my knowledge until a few weeks ago when I finally got around to building one and got hold of an old kero blow lamp as a heat source.
After a 5 mins or so after a far bit of oil and assistance it finally started to run by itself. It lasted about 5 mins and started to slow down then it stopped.
I found that the arm that works the central piston had come loose from it shaft. Looks as if the locating pin had sheared some time ago and the rust has started to let go. Tried to fix it by drilling out the pin but that was less than perfect. It worked for a while and was particularly good one very cold night. The first time it ran it was lucky to do 150 RPM but on that night was probably closer to 300.
Since then the pin has worked loose again and the timing has slipped significantly to a point where it will barely run. Before I dismantle it to rebuild the shaft and create further problems for myself I have few questions if you can point me to someone who can help.
