auger pipe replacement

I built the last 300 stokers while it was done at efm. I trained the guy at our sister company to take over my job and I and he have used Never Seize on every single screw and bolt in all the stokers we have built, except for the 6 bolts that hold the burner plates.

For my own personal equipment and that of my customers (non-efm), I've been using Never-Seize for close to 40 years.

Not sure if this will help in your situation but if there is coal in the bin the pipe can be pounded into the coal pile with a sledge and block of wood. The worm can then be "screwed" into the pipe and coal in it using a big pipe wrench.

The EFM 700 900 1300 are set up like you Van wert the 350 & 520 go threw either side of base .
Also the 700 900 1300 can be fed threw the front of base removing the ash door and putting it on either side of base
or setting it up to fed either side of base .

It is a AP-520 a AP-350 would have a 2.5" spacer plate in between the blower mouth and base side plate that is the easiest way to tell by looking at it unless you know the measurements between the two models or pull off the Jackets and look at the info plate welded on the front or back gives the date model ser# and boiler maker the # on the stoker may not match the the boiler top being it could of have been replace over the years Doubt it but possible.

What do you mean by the jacket?

stoker-man it was installed in 1957.

The jacket is the blue sheet metal surrounding the boiler and base.

It looks line an S20 like mine which was installed in 1959 and still working great. If you look on the blower housing by the gearbox there should be a tag with the model and serial number on it.
