I do not believe.

Is it filled with an insulating material?
What material is it?

Sorry I have never taken one apart. I've heard others say there was sometimes brick dust inside--maybe others can comment. Unless you run the engine for days at a time, I doubt it makes much difference. On other engines they appear to be empty.

Hi Brent,
quiet I do not have to modify the piston displacement ... it was just my curiosity.

Thank you
Davide

Default refractory cement casting

I have analyzed the work of reconstruction of refractory bricks.
And if I did a refractory cement casting?
What is your opinion?
Do you have any advice to give me about this?

Thank you
Davide

Thank you all for your valuable advice.

In the end here is what I did today on the furnace:
a mix of refractory bricks and ceramic fiber (similar to FiberFrax).

What do you think?

P.S. to next post: Piston Gasket

Excellent job. I hope your leather is flexible enough; it should be very soft leather.

Info on displacer piston I have had some original apart and no two are the same . Most have A 1/8th thick by 1 inch wide band rolled to fit inside displacer piston . It is riveted on 3 or 4 places to keep it in place in center of piston One had A tin can 1 inch thick laying on center band .not air tight .kept insulation from going to bottom .Insulation looked like Rock wool used in our home in ND in the 1940s one had A 3 star piece of metal laying on it and looked like A roll of asbestos dropped in there on top half of piston I have not seen A piston with any thing in bottom This info is Ericsson engine only

A little more info on last post One piston had a 1/8 inch thick plate laying on center band with A 1/2 inch hole in it kept temp from rushing back and forth all pistons had the center band and I think it was to keep transfer piston from tin canning on pressure and vacuum stroke This info for Ericsson engines only I need to do more research on 10 Ericsson Do not know for sure how many changes were made on them all posts put up by me are open for correction

Hi Brent,
regarding the softness of the leather, I'm not perfectly satisfied.

I worked a 4 mm (0.157 ") leather and crushed 3 mm (0.118").

This, however, has compacted and stiffened the leather.

Maybe I'll have to do the work again with a 3 mm leather

Hi Buster,
my engine does not present this modification, between the power piston and displacer there is no seal.
But is it necessary to improve the hold of the power piston?

Sincerely I do a lot of effort to understand 100% what you've described, can you explain better with photos or with a drawing?

Thank you

Davide,
I think Buster was referring to what he has found inside displacer pistons (your earlier question). Don Worley has spent some time (and money) finding the most suitable leather for Ericsson engines. You can get one from him that will fit and work without additional cutting, soaking, drilling or experimentation--and they're relatively cheap.

As for Don's seals, he replied that he is not ready at the moment, and that he will tell me when he will make a new lot, but in the meantime I wanted to try it alone

Colo In Post number 29 I was referring to displacer piston and how they were made On the piston leather get very soft leather about 1/16th thick smooth one side I think on 6 inch engine it needs to be 5 inch ID and 7 inches outside put white grease on it put it in smooth side to cylinder wall You are ready to go Try it keep me posted Buster

RIDER ERICSSON Restoration:
there is no trace of the great snowfall forecast for northern Italy.

So this morning I finished the paint stripping and then a good wash with the pressure washer.

New question.

During the cleaning, 4 holes appeared around the cylinder, inside the perimeter of the furnace. They seem to have been closed with a kind of mortar.
Maybe they were for the gas furnace, and then the engine was converted to wood / coal?

BRANT, what do you think?

New question, last for today.

When I disassembled the pistons, I noted the "tightening dimension" of the displacer.

This adjustment has to be very precise?

What would be the ideal setting?

Thank you

Today I practically finished the job. Only the water pipes are missing.
But for today, be satisfied with the photos of the pump

If you are speaking about the substance inside the dis-placer piston, in my engine it is mineral/rock-wool (which seems to be similar to an early fiberglass). I hope this is not exposed in any way as the engine will not run without a perfectly sealed dis-placer piston. DO NOT OPEN IT! If it looks good and there is no sealing issue, leave it alone and put it back in when restoration is complete.

Hi Brendon,
yes my displacer looks good, I do not want to open it, it was just my curiosity.

Hello,
the pump packing has two 1/4 "threaded holes.
It is original?
In the hole I have to put a tube to recover water leaks?

Thank you
Davide
