I had a previous post in here from when I first joined and was learning all I could about coal boilers. Since then I was updating the old thread which was kind of misleading so here we are the good Ole Allen stoker gets it own thread for the current happenings.
Tonight when I got home from work doing my normal routine went down the check the stoker and only had a red spot the size of a quarter. Noticed the shear pin had broke for the screw. Probably
my own fault i just had a random 8/32 bolt in it but Quick fix non the less but by the time I got it done I had lost fire. Just got it re lit.
Had to work on the Allen today on Sunday night I came home and realized the house was @ 69 degrees instead of the 72 I had it set for. Went down to check it out the reset button on the motor was popped up. Pushed it back in and it ran fine until sometime today. I was getting ready to leave for work when doing my daily routine went down to check on it I opened up the door to check the fire and that's when I only saw about a 3" diameter fire. (my pot has a 16" ash ring) so I knew something was up. The reset button popped again. So I decided to swap motors with the spare I have. Last year I took a trip up to Mt Carmel PA and was able to purchase an entire stoker unit from someone who removed an Allen for a gas furnace. Any way got it swapped and we are good to go now. This motor even runs quieter then the last, the stoker assembly that I got last year also has a different coupling setup then what was on my boiler. My boiler had a custom motor with an extended shaft and standard love joy connection. Where as the parts stoker has a standard shaft length motor and a longer spider for the coupling. Here are a few pictures

Probably not a bad idea Rob, the only real issue I have ever had with this boiler is the drive motors. My first year living here the one on it went out. Then I couldn't buy one off the shelf and had to get it custom which took a month. (Someone converted this to take one with a 4" motor shaft) luckily a local ship was able to get my original one back up and running. 2nd heating season at my house the original started making noise so I swap for the brand new one. That only lasts a few months (my own fault to much thrust on the shaft because of lovejoy connection. Swap back to original again. Then I took my new motor to work to examine it. The tail end bronze bushing wore out. So I machined a new one and bench tested it. It was good so I swapped it back on and that brings us to current day. And now to end my rambling on post. I may take my 2 long shaft motors to the electrical shop and get them rebuilt. Or just buy new.
L , this summer I did some test runs in the driveway to see what was needed to burn a load of hi-iron coal in an Allen . While doing the tests the coal was grinding , I found the ID of the old auger tube was built up with scale, that caused lots of drag and made the motor work hard.
Also the first ring was potruding into the goose neck on the back side so the coal had a hard time flowing into the pot.
Turning the auger by hand showed where to resistances were located .

Dave, you have an Allen to? I felt as if I was the only one.
Thats great to know there are more out there then mine. you definitely don't see them now a days they are getting rare. Just out of curiosity how much do you know about these stokers? I know mine has a 16" top ash ring the stoker unit I bought for parts looks to be smaller. Did they sell these stokers in multiple sizes?

L, If you take the top ring off that you made , and pull the burn plates out , that next section captures the ball bearings and will swap with the small one you bought. That will drop the unit down in depth and width of the coal bed .
Any way got it swapped and we are good to go now. This motor even runs quieter then the last, the stoker assembly that I got last year also has a different coupling setup then what was on my boiler.
