Feed motor question

Feed motor question

PostBy: k9 Bara On: Wed Oct 07, 2009 1:55 am

The attached picture is the feeder motor of my Econo 1. It was loud at first then after shutting it down and retrying it the motor locked up and would not turn. I removed it from the stove and then separated the case. The gears were in dire need of grease and were showing some rust on one. I removed them all, cleaned them and cleaned the case. I put gear oil on for reassembly and the motor worked fine and much much quieter. Is there a recommended grease for this? Just high temp synthetic? Thank you again,

George

When in dought, probably worth a call to manufacturer. Nice catch on the problem. Actually it's a good thing you mentioned it was a feed motor gear cuz at first glance it looks like an antique clock movement mechanism. :lol: What do you think Joe in NH? :lol:

Thank you for the reply's guy's. If we don't here from Jerry, Ill give him a call. I hate to call and bug him. The gear oil is to thin and leaks out the case, I suppose I could seal it if needed.

Thank you ,

George

Try hi-temp wheel bearing grease, that should stick pretty good. I think I had a can out in my garage, pretty sticky stuff.

Maybe a thin film of hi-temp silicon around the case might at least keep some lube in & moisture out.

Motorcycle chain lube would be perfect -- no drips, dries tacky.

Our motor manufacturer states never to try to repair the motor or gearbox. Must be sent back for warranty work. (1 yr) They do not recommend opening up the gearbox, and they will not say what grease to use. BUT, since I want thing to last, I would use a high temp wheel bearing grease, but not too much. Since the motor does not set level on the feeder it is very important that the grease does not brake down and leak into the bushings of the output shaft. This would cause the coal fines to collect at the output shaft and ruin the bushing in no time. With the old style motors running full time (before Coal trol) the casing would get to hot to touch. The grease would run to one side of the housing but would still lube the gears as they were turning. Sometimes a little dab will do ya. More isn't always better, except with beer.

Understood, Thank you Jerry. I will try the bearing grease. I will still need to order another motor as this one is not longed for this world I'm sure.....beer? 1 more day and I can have a few. Not during the week but on the weekends... :) :D

Thanks again,
George
