I'm servicing my AD5 for the first time. When I disassembled it I
noticed that the top-most ring around the piston, which is made out of
a hard plastic, is not solid but has a "cut" in it (similar to a
ring from any internal combustion engine) presumably so that it can be
expanded and removed. However since I did not take it apart when new
and that particular part was not included in the seal kit I don't
know for sure if it's supposed to be a solid ring or not. Curiously
the schematic does not list the part.
If anyone can confirm what the state of this part is supposed to be
I'd appreciate it.
