Got the spare gearbox/motor from Jerry @ LL, Wow! that was fast service!
Weird thing, The fire look like it was going out last night on the smaller 40K Burner, I checked it, it must have had something blocking the plate, it was kinda making a clinking/grinding noise and then the Stoker lever came unscrewed off the shaft and stopped pushing the coal, ripped it apart moved the stoker plate back and forth and it seemed to fix it. The combustion blower wasn't turning full speed either, shot it with some WD40 and it took off! I think it was getting some fines in the motor from the stoker mechansism....will have to take off and clean/lube it.
This morning it was glowing nicely!!
Phew. At least the weather is warm and doens't matter if one side goes out temporary. It mostly idling anyway.
