Stoker motor noise comparison

My Hearth unit has always had a noisy stoker motor. I ran it from December 17 last year until mid March and before firing it up this year I took it all apart to clean, inspect, lube, etc. The stoker gearmotor has grease in it, but due to it being mounted at an angle and being near the hottest part of the stove I found all the grease had melted and collected at one side of the gearbox. I moved it all back onto the gears, but I'm sure by now it's all back at one side again. Is there a grease that will not melt at the temps the motor is subjected to?

My main question is, how noisy is your stoker motor when it runs? Mine has always sounded like it's grinding and is amplified by the steel stove body. Sounds a lot like an electric can opener running loaded with a can. I tried isolating the motor assembly using RTV, stove gasket, hi temp RTV sheet, you name it, but it's still quite noisy. The motor running in your hand is near silent so I know it's the stove itself amplifying the noise/vibration. My buddie's Alaska Channing only makes a very slight ticking noise so I wonder if maybe my gearmotor is a noisy one or if it's just the design of the stove?

I'll probably video mine tonight and post it if I can get the audio to sound correct.

Thanks in advance.

I think it depends on the mounting and gearbox design, my Keystoker is very quiet, I really don't hear it. The LL is a bit noisy, plus it also gets pieces stuck under the carpet pusher and starts grinding a bit louder. It's in the basement, but the chimney goes up thru the middle of hte house and in the corner of hte bedroom, so you can hear it when you are laying in bed....

Maybe put a hi temp gasket or some type of felt washer between the stoker motor and the mounting plate?

I've already tried RTV sheet, RTV goo and stove gasket material. Didn't change it at all.

If you're talking about JUST the stoker motor, mine is practically silent. I get some mechanical clicking from the movement of the push-block, but otherwise I can't hear it. The motor is not mounted on any rubber stops or gaskets that I can see.

Now, the BLOWERS drive me out of my friggin' mind. If anyone knows of a nearly silent blower, I'll get in line first for it!

do you have a Leisure Line stove?

I don't know what the limit is on Hi-Temp wheel bearing grease is. Might want to check on that.

Nope, Harman Mag. Sorry, I jumped in there without thinking. Telling you how my Harman works doesn't do you a lot of good, does it?

we moved the combustion motor onto the basement, Wow real quiet now. Had a sheet metal shop make an adaptor to fit the stove,and fan, drilled 8 holes, used pvc pipe from the basement with 2 fernco rubber boots. Works great.

I'm asking about stoker motors, not combustion or convection motors.

thanks!

The best way to describe mine is it sounds some what like an electric can opener when stoking, not very loud at all.

Mine also. When it isn't pushing or pulling the carpet you can't hear it run.
