Larger drive gear on Harman auger

OK,as promised.I put on the larger auger motor drive gear.Did not buy buy kit,just bought the motor gear and longer chain,as,did not need the expensive bracket,as you can take out the rubber bushings,and mount motor,with washers,per a Harman bulletin,and did not need the nylon adjuster,as it does not rotate,and you just spin it to a different position.And,my inner gear showed no wear.So,weather has been a bit up and down,only fired stove 5 times since change,and accounted for temperatures.The bigger gear puts more pellets into burn pot,whenever it runs.1 it puts more pellets in,for startup,but not a lot more.2stove warms up faster,convection fan comes on sooner,probably because of the initial charge.3 The flame going up and down(because of the exhaust probe)are higher,when low.4 The room blower stays on higher,when flame is going out(thermostat).5 The temps,from front of stove(blower output) and side of stove,are,generally,20 degrees higher.Now,I always swore,my old original control board put out more heat,than my newer "platinum" board,but also ran very dirty.Seems to me,if you have a chain drive,and switch to the newer board,you should do this gear conversion.It is using more pellets(short term),but burning clean.A dam shame HHT does not release Technical/service bulletins,we all know they are out there,but seems like Harman no longer wants their stoves to last,so they are hiding info,same as GM and Ford used to do.Will update if i see things change,but gonna leave the "update" in the stove,for now,burns nice.

 

Hey Bob
I must have missed the original thread, what stove are we talking about? I have a advance 2 (2004) chain drive, there is a updated kit for the sprockets ?
Just trying to understand the end result
Thx Cliff

 

06 accentra The small gear on the motor has been discontinued.Also,the motor mounting bracket has been redesigned,no longer uses the rubber bushings.A while back,when my board was dying,I put in the newest board.Store ran better and cleaner,but I always thought it put out slightly less heat.The new bigger gear seems to have put stove back to where it used to be,puts out a bit more heat.I did not buy the kit they sell,my inner gear is still good,and i had already mounted the motor solid,using a few washers,so i only purchased the one gear,and the longer chain.My next step is,i have ordered a bushing,to make the chain tensioner actually roll/rotate,instead of just being a "shoe"

 

OK,stove on 2 times today,I do notice the extra pellets on the initial startup feed creates much more smoke upon startup,causing a bit earlier buildup on the glass.Someone else noticed this,also,after a sprocket "update". There is 1 setting lower(time auger runs to fill pot for startup),so I have switched it,and we shall see.At the worst,it will not be enough pellets to light stove.

 

OK.Sun went behind the mountain,stove kicked itself on.I had switched the micro switches to the lowest setting,available,for my stove/control board.Much less rolling smoke in fire pot,initial flames much lower,back to what I would call normal.Before this test,I switched the micro switch,scrapped the burn pot,and,scraped all ash/debris out of the pot,for a fresh start.Much less smoke in fire pot,before ignition,no "poof", this all boils down to Harman not releasing information.

 

Yep,stove ran once last nite,then again this AM,changing the setting works just fine.

 

OK,Ssyko got a batch of pots for Harmans,sent me 3,for testing.Soldered them in my old control board.As I expected,the bigger gear,with the older control board,stove was cooking!Never sen it that hot,too hot in my opinion,350f on the sides,and almost 400 out front vent.I would never recommend the bigger gear with an older control board.So,I switched gears,to test the pots he sent.Stove worked fine,all functions worked,and all readings,on Harman DDM were good.I did reinstall newer board,just because stove functions better than the original board.Have not decided weather to put bigger gear back on,but probably will,as,with bigger gear and newer board,stove warms up faster.That is probably the extent of testing I am going to do this winter,lol.

 

Hey Bob
Got a question i have a 2004 harman advance 2 and was going to upgrade to the newer burnpot (double backing plate) would i have to change to a longer auger? My auger is worn at the end so i was going to replace anyways. But because the newer burnpot is farther forward should i stay with the 2004 auger? Also I'm going to do the gummy fix while I'm in there.

Your thoughts?
Thx Cliff

 

Augers did not change.Updated burnpot is not affected.The air bypass kit pretty much makes it so you could almost never burn off the end of your auger,also.Many people have had the end of the auger repaired by a welder.I have not kept up on which stoves have updated burn pots,the 52I is one I positivity know of,I think yours is also.Harman is terrible for customer support,they want you to pay a dealer for this stuff.

 

I have to agree on Harman's customer support. My PB105 pellet boiler had a warped burnpot while it was under warranty but the Harman dealer was out of business (they probably should have sold good pellets, but that's another story). If I want to replace it now, I'll have to find some other dealer and buy it. I'd rather just fix it.

 

Thx Bob,
I'll probably just replace the auger given the fact its original and the bearing is a little tight anyways, good to on the length didn't want any issues with an auger tube flame up. Looks like a good summertime project, new auger, burnpot with gasket, and a flame guide and the air kit.
Thx Again

A good point here is that if something goes wrong while under warranty, get it taken care of! Ive seen way too many stoves a year or two over warranty, with issues that would have been covered while under warranty, but the owner didn't do anything about it until it was too late. The dealer who sold the unit is no longer in business? Harman will arrange to have another dealer rectify the issue. We have had two dealers go belly up in recent history, and have been asked to cover warranty obligations....not really a problem, just have to fit them into the schedule.

 

Its a pretty easy project, just be sure to get the correct auger......know if your stove is an ultralight feeder or not. Theres two different augers....-00465 and -00565

 

Thx for the info, my manual shows Auger# 3-50-00365, its a 2004 Advance2. Which i guess i can use 00465 i assume?
Thx Cliff

 

Serial# would be best indicator for the right parts, not discounting what the manual says but just to be safe!

 

Thx Bob
Appreciate your thoughts and help, its #9428 Harman advance2 also a up graded burnpot should fit?

Thx cliff

 

Whoops thought i was still talking with Bob, sorry Ivanhoe

 

Augers pertain to the feeder unit your stove has.Yours is old,takes the older auger.Over the years,harman has "upgraded" parts,usually to fix existing problems.Some harmans had long ignition times,some had "slow" ignition times(which actually caused glass breakage) .Harman does not release information,and most "harman" techs are working under the license of their employer,and have had no training.But,I still consider Harman one of the best stoves made,other than some of their new models.

 

yep.....the oldest auger was -00365, which they havent made in a LOOONG time! The replacement is the -00465........the -00565 WILL NOT work

 

Lousy,
Thx for the info, 00465 it is
