Elektro runs - homemade Teflon rings and new band boiler
By: komet163b Date: March 29, 2022, 12:19 pm
---------------------------------------------------------
Elektro's, in my experience, are problematic three out of four
times.
Blow-by, in both the valve and piston areas, is very common. I
did just
get one that runs, with minimal maintenance, just as it came.
That engine
is for another thread.
This is the Elektro that came without a heater and loads of
blow-by.
Well, here are photos of how I replaced the heater (the pix say
it all)
and arranged the grooves (done by hand with a tiny file) in the
piston.
Forget trying to see the 'twisted Teflon tape' rings - too
small.
I added a video and some pix. I'll be replacing the rings to
tighten
things up a bit but there is no rush as this machine is a...
Runner!

Here is a link to a pair for sale right now.
One caveat - the leads are 'flat' silvery wire.
This makes it difficult to hook to the terminals.
Won't stop you, I'm sure. Please note the socket
I used as a buffer. I did round the top to fit
snugly against the bottom of the boiler.

If I had seen these Before the ones I saw first,
I would have purchased them because they have regular
wires.

I just ordered one of these myself (the 2nd one) for a B31. I
figured what the heck! Is that a socket in the middle? That is
ingenious (in the B31 thread the member made a brass bit). Also
in the B31 thread he mention "mica" - I assume so it can be
around the outer edge? I can't tell, do you have mica too
around the heater (around the outer circumference of the
heater/inner tank)? I assume that it is important to have that
barrier between heater/tank edges.
I am also looking at Insulated High-Temperature Ring Terminals
from McMaster-Carr
(HTM) https://www.mcmaster.com/high-temperature-terminals/
(300 F) to
put on the end of the wires (darn out of stock). Might anyone
know the screw size of the Empire's inner studs (I think they
are 10-24)?
Lastly, thank you Wayne for your post and URLs to the heaters -
you are a star for sure!

Guys.....I'm glad others are picking
up on this. Keep in mind, I cut off
the portion that has the socket-thing
on it. The point is to get the band
pushing out against the inside of the
heating chamber to improve heat transfer.
Anything you can do to get the heat away
from the band, and preferably to the walls
of the chamber is the objective. I use
a big socket that fits snugly, which also
helps to push the heater against the walls.
Good Luck,
Wayne

I get you would cut off the molex connector. Did you keep in
the socket wrench in the middle or temporally used it to push it
out to the walls of the tank (removing the socket wrench before
putting the cover plate). In the B31 thread, it seemed like he
kept the brass slug he milled in. I also assume you put mica in
between the tank wall and heater, to protect from the heater
shorting electrically to the tank? Or is that not needed at
all?
My B31 is missing the cover plate but actually had the heater
(sandwiched between lots of mica) then an iron band that pushed
it to the walls. Nothing in the middle other than a big hole -
say like a donut. So I don't know if Empire had originally an
iron/brass core in that center void / hole.
Sorry if I am being stupid, though I am ignorant how it was
originally from the factory :(

I did not work on an Empire vertical, only the Elektro. They
are related
of course. I can say that none of my Elektro's came with any
heat sink that
sits in the middle of the element. AI used a large socket to
force the element
against the walls. No addtl mica needed as the element was
still sealed.
