EFM Motor Noise

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Kenny. From a past document:
This motor is factory manufactured to run
in a counter-clockwise direction when viewing
the shaft from the front. Verify that it is running
in a counter-clockwise direction before putting
into use. A reversing switch, located under the
black plug at the bottom of the motor will change
the direction of the motor rotation.

It depends on the load. With a cold start up and no load on the boiler, I think mine takes 30-40 minutes to come up to 160 degrees. Just estimating, I have never timed it.

How are things running now?

I seem to remember someone saying the old-style slotted crank can't operate at less than four teeth of feed. Regardless, four teeth is a very common setting...why do you want to run less?

There's a good chance you can convert your stoker to the modern feed system. It all depends if you bearing bracket assembly is machined on the end. See this picture for the machined end:

No, I don't think it is either. You should be able to get a good used one from somebody here.

You don't need a shear pin where the auger is connected to the coupling. The coupling connection uses 2 cotter pins. The only shear pin needed is the pin next to the clutch ass'y.

What problem is 4 teeth of feed causing? I feel like I am pulling teeth here...I just want to make sure you aren't trying to correct a different issue by reducing the feed rate.
