The nameplate would be on the back under the cleanout plate.

I think that is a 350, not a 520. How wide is that bad boy?

Either that is a coincidence, or you did not have the correct shear pin in the end of the clutch shaft. Put cotter pins in the coupler and a shear pin in the end of the shaft.mooseman100 wrote:I been using efm shear pins on auger coupler and the end of the shaft.

Earlier you mentioned that you are filling large sacs to get the coal into the bin. Does that mean you are dumping on the coal on the ground, then scooping it up and dumping it in the bags?

The bags I use are 1 ton farmers grain bags. They get filled right out of the coal delivery truck or chute at the breaker. I then stack them on pallets under pole barn. When it is time to load into bin I use skid loader and set the bag on a special pallet with hole in the bottom. Then I lift pallet 8' in air and open bottom of bag over the chute and let it run into coal bin. I do have to set special pallet on the ground, which is gravel driveway, when I am switching from storage pallet to filling pallet. I have seen occasional piece of gravel get on the bottom slats of the pallet. Next year I am going to put filling pallet onto a piece of plywood to eliminate that chance.

According to those plates the boiler is a 1960 and the stoker is a 1964. Looks like the crank and clutch are off of an earlier unit because the feed rate adjustment is on the crank, not a thumbscrew on the clutch.mooseman100 wrote:Only plates I can find
None of this would cause shear pins to brake.

It is missing the jam nut from the back side of the check pawl stud. Not relevant to the shear pin issue unless the stud has moved and there is a lot of backlash in the ratchet.

That min.serv. 19? threw me for a loop. Mine says min. serv. 400. Mines a 520 so I assumed the Fitsgibbons was an old 350. It's not. Anyway, it has a spacer plate for a 350 on the stoker. It holds the stoker farther out from the base. It changes how the auger and tube fits in. It pushes up on the tube and makes the auger tight to begin with. Could be a major reason for the pins shearing.

Now you are definetly above my head! LOL So maybe we need to take space plate off?

I think SVRC in that pic is 134 and I found a pic of a COBCO 520 that had SVRC of 155. I think both are light - would have expected 166+. Maybe somebody forgot the big pickup factor EFM used for rating. 400 sounds like something in the 900-1300 range.Scottscoaled wrote:That min.serv. 19? threw me for a loop. Mine says min. serv. 400.

Spacer plate moves pot toward mounting side by 1"? So it would push up on the auger tube by approx. rise/run of auger pipe x 1" = 3/16" where tube passes through opposite side of base? I agree it's worth checking, but not sure if it is significant for the pins..
