In light of these latest findings...you may just have to "persuade" that pot bushing to accept the auger as it is. :x

fired up the oil fired torpedo heater so we can work out there, thank God my buddy cares enough to help me out with this mess, i rent half the building off of him and keeping the pipes from freezing out in the shop is my responsiblity.......just trying to get this mess fixed before i have to go in the hopsital for surgery again on the 11th. after i get home i will be laid up for at least a month.

working on a complete teardown of the stoker assembly, my buddy that owns my shop offered to pay for all new grates and gaskets and hardware

trying again to get the blower housing off the pot since i see no other way to fix it right

the grates are original and they have warped, 1/4" gap at the bottom between the grates and the gasket has deteriorated away.
i have probably put 60+ tons of coal thru this thing since i saved it from being made into cat food cans in 2006

Possible steps for temporary amateur Rube Goldberg repair:

1. Insert short pieces of rod (or something like finish nails) through the "oval" parallel to but on the outside of the bushing to restore the bushing to its proper shape and location.

2. Reinstall auger, and secure the filler pieces with furnace cement.

3. Say a lot of prayers to Saint Frederick of Altensteig (the patron saint of old EFM stokers).

4. Start plans for replacing the pot.

As always, should you or anybody else reading this actually follow such a plan, the secretary will deny any knowledge of your actions, the existence of this post, and even the existence of this forum. Unless it works. :lol:

Good luck.

Sounds like a good idea--wonder if you could use shim stock cut in shorter and shorter pieces to fill the gap?

Like this:
-
---
------
---------

Or braze it? don't know if would hold up to heat. Anyone know how hot it gets there? Guessing way too much for any kind of epoxy.

Another really dumb idea that just might work, but would REALLY depend on getting the right hardness--or it would wear out really fast--bore out hole, install thicker bushing (larger OD/same ID).

In the mean time--how hard would it be to just blow down the water supply system and put camper antifreeze in all the traps, let the bldg go cold? Like what folks do for their camp when closing up for the winter. Maybe totally impractical, but, if you aren't working there anyhow...

could not get the blower off the gooseneck, welded some steel to the pipe and heated glowing red and pried....nothing

did manage to get the pot off tho, torched the 4 bolt heads off.......why did efm not give room there to get to the bolt with a socket?
open end of the wrench rounded right off, so we torched the bolts.....the new bolts are going to be allen head.

now i either have to get a new pot or get this one sleeved, i can really see the groove once it's apart, will get some pics in a little while after my buddy is done ripping it apart.

cant leave the heat off because the water goes from my house, across the garage to my buddies house on the other side, and the washer we both share is out in the shop, he wants the garage heated and is paying the bill for all the parts. at least it warmed up to above freezing.

You heated the cast portion around where the tube goes in to red hot and it wont come out? Try making a slide hammer on the auger pipe , hang the pot assembly from a vise ,the vise bearing on the shoulder around the pipe with the pipe hanging down. use the slide hammer to "pull" the pipe as you heat the casting. a piece of pipe or square tube would work nicely for your silde and some stock welded to the bottom of the auger tube (after you put your slide on) will give you something to hammer against. Itll come off......

Never mind I thought it was the auger tube you couldnt get off :oops:

the auger tube just came off in pieces

good news!

i took the lower pot down to scrapperjr in ravine this morning and he fixed me right up, he got the bushing to fit nice and not rub the auger and he got the old feed tube out and a new one fitted.
also picked up the gaskets and hardware needed, and six nice used burner plates.
thanks so much steve!

as soon as i get some more cash going back for a new ash door for my efm.
