With the worm removed, knock the old bushing into the pot. It will push straight through, there is no shoulder.

Thank, Gerard

Gerard, you push the shear pin until the head bottoms out. Part of the pin will stick out the other side, gently bend that enough to keep the pin from pulling back out.

It should look like this:

The boiler is up and running since 10/31/2011
I have 1 zone for floor heat out in the in laws quarter, 1 zone for water to air heat exchanger for main part of the house and 1 zone for indirect fire water heater. The main part of the house is a heat pump and I'm not using the heat from it and there are 3 zones on the heat pump unit that control the 1st floor, 2nd floor and sun room,I still control the heat using all 3 t-stat, I have the cir pump running full time because the unit is in the attic along with pex pipe feeding the coil, so I dont have to worry about pipe frezzing on me, also a small Modine unit heater in the garge for some heat, to thaw the snow on the cars,lol
This been a very good project to do from start to end and would do it all over again.
You will see a pic of the right side of the boiler where the auger come thru the base, that box you see is a mirco size coal in about 20"x20", the coal comming down the 6" pipe from the mother coal bn that outside, this way I dont have to deal with moving coal and making dust (maybe lazy too) I made 7 ash pans, now in the process using the cycone to clean out the ash in the boiler instead of using the ash pans, just need a more powerfull shop vac or dust collector, they will be outside next to the coal bin and the house thru the basement window
Gone thru 2 tons of rice so far from Harmony, gotta love that stuff.

I want to thank everyone that help me out answering all my question, you guys been great

I think someone broke into your house and stole the covers off the aquastat, timer, and circulators. :)

I thought I saw something spraypainted on the side. I did something similar with mine:

I bet your basement is plenty warm with the "beast" running down there.

I kept the cover off while I was doing some fine tuning for the past month, with the basement too warm, time to put on 1 1/2 thick fiberglass insulation, hope it lower the temp somewhat, if not, there be a nice finish instead,lol

How do you know when it's time to drop more coal from above? Or is it constant feed? That's one way to keep CO out of the house.

I dont think that tin coal bin is going to hold up too long. Wet coal will rot it out quickly. Once your mother load freezes how are you going to load your hopper?

The coal might receive a little heat from that shute pipe, (at least the coal covering the entrance) if the coal is stocked up early in the year it should have time to dry. Is their drainage for the water outside so it doesn't flow down the pipe ?

the coal are already dry before it goes down the chute into the mirco bin and there is a drain in the mother bin, worst come to worst, just make another bin for free again, I cant go wrong. Plus,I havent had any problem with frozen coal yet and dont think I will, Here the way I see things, try something new out and see what happen, let not worry about the "IF" let try things out and learn from it. Now, I'm looking for something eles to do yet, havent found one yet but will, lol. Life a Coal.
