    Hello

    Working on a used 25-PDVC. I pulled the top auger and it basically looked good but just had a few pokey little burs on the auger see red arrow in first pic.

    Has anyone looked closely at their augers lately? Do they need a little sprucing up?

    Here are the steps I took to pimp up my auger for less resistance and longer auger motor life while trying to avoid the binding and jams.

    In my experience, even the cheaper auger motors work pretty well after this treatment!

    1. Remove all black carbon with a wire wheel
    2. Ground down burs and jagged edges with arrow shaped grinding stone.
    3. Smooth it all out with Emory cloth from Home Depot
    4. Clean up with a rag an Acetone from Home Depot
    5. Mask up bottom gasket with masking tape and spray down shaft with Dry Moly Spray

    Also I will smooth and spray the auger tubes and grease the bearings!

    See final finished picture beauty shoot! The auger is real slick to the touch!

    I am almost ready to pull the augers for maintenance, so I will probably follow your pictures on this.

    The stove in the pics above is a 2007 and they were very dirty. Also the bottom auger bearing gasket is partially melted and in bad shape, so I ordered a new one.

    I am due for this as my stove is 2008 and I have never had augers out to clean tubes,
    I can feel and see the carbon building up in the lower tube so come warm weather it is time.

    Sounds good and will give it a try as way over due.
    So we be going down below zero tonight? I think so and have Cubex burning.
    First year burning them and yes hot but lots of clinking and green flame with unburnt pellets. but hot.

    Hello

    With my new longer extension and quick fit brushes and stones, I could not only clean off the carbon but also grind down the knit line in the auger chute so it is smoother than when the stove was brand new!

    Hello

    Well, after grinding and buffing the auger chutes, I smoothed them down with emory cloth and then cleaned them out with Acetone.
    To add a nice smooth protective finished, I sprayed them down with Hi Temp Dry Moly Spray.

    The upper Auger Bearing plastic gasket partially melted, so I replace both auger bearing gaskets for good measure!

    Porting and polishing, lol, you've picked up some more HP, see you at the pellet stove drags:).

    That melted bushing made me glad I replaced mine with the sintered bronze, I wondered about the possibility of the plastic's heat worthiness.

    Yes, and now some hi temp grease for smooth running!

    Where did you get the sintered bronze gasket?

    Sintered bronze auger bushing, not gasket. Sorry, thought we were talking about a plastic auger bushing; that photo was kind of fuzzy and so were my eyes :p. Bought at a local brick & mortar bearing supply company. It was a standard size that they had a lot of on hand, so they gave me a good price. Evidently you are not supposed to grease the bronze bushing because that can clog the porosity that would slowly feed oil to the surfaces over its lifetime.

    Hello

    I had the opportunity to work on a 25-PDVC yesterday with a top auger binding issue just like yours, so as an experiment since the bottom auger was turning ok and to prove a point, I tried this:
    I pulled the Top Auger only, wire brushed it clean from the dirt and carbon and the auger chute, grinded off the burrs, emory clothed them smooth, sprayed the dry moly and put a brand new Gleason-Avery auger motor on it. Fired up the stove and to my dismay, the same problem of the top auger binding after startup and the fire petered out! All the pellets got stuck and mashed in the front of the top auger until the jam occurred. This makes a impression after all that work! Not a good one! LOL

    So I cooled the stove and cleared the jammed pellets, and pulled the bottom auger. Wow it was the most charcoaled auger I have ever seen! It was black as an eight ball and dirty as soot! I then used the procedure on it and the shaft. since the bottom auger works more, I then put the New GA motor on the bottom auger and the bottom auger I moved to the top.

    The stove has been running flawless ever since. I did recommend another new auger ball bearing auger motor to be installed at the next full yearly cleaning.

    That cemented the process for me. LOL Always do both augers!

    Another Important lesson here!
    If the bottom auger is NOT turning the way it should, it can also cause a the top auger to bind up!
