Auger shaft install (distance) & Auger motor temp 7000-500. Quadra Fire CB1200

[louhazosc]

Hi all,
Simple question.
QuadraFire Classic Bay 1200. Auger Motor 7000-500.
Been having auger motor issues and trouble shooting the low $$$.
It would intermittently shut off and then a horrible squeaking/squealing and now more of a grinding.
FYI Trouble shooting. All learned from posts on here.
- Vacuum switch new
- Took out auger motor and shaft. Hit it all over with a wire brush on my drill. Treated with graphite powder spray and straight powder in smaller parts. Put a new bushing on.
So as I said - all the <$25 fixes.

So I got the squealing to stop but now it is more of a grinding. It 100% is the motor. I can feel the vibration on it when I touch it and its turning.

So the question: Is it at all possible that I set the shaft in too far close/away and that's causing the grinding noise? I did my absolute very best to set it back exactly as I could see the allen screw markings on the flat side and its grinding.
When I get the new motor is there a sweet spot the shaft has to be set in distance wise?
I am not to break into the motor cause why...if its bad its bad.

Question 2: Does the motor need to be warm? I'm asking this as I'm typing sitting next to the stove and the noise is stopping. I did all the work in a 20 degree barn. 30 min. sounds fine now that its up to temp. huh?

I don't mind dropping $100 for a part after a decade of running perfect. Just really trying to understand this stove fully. Learned a lot from you guys every season and happy to learn a bit more.

Thanks!

Hello
Q2 - If you have the old gray control box then yes the whole stove has to be warm because there is not enough vacuum because it starts on low for the initial pellet feed. The new clear control box fixes this issue.

Quadrafire Feed Motor Fury and the dreaded CSS - Cold Start Syndrone.

The old Quadrafire Contour was humming along until the deep freeze came and it would not start when it was 23 Deg inside the workshop for 2 reasons 1. The feed motor would not turn. The thermocouple and ignitor work fine. If I do a jump start, and fire the bugger up manually, the auger starts...

Q1 - I had the same problem last night. The grinding noise is caused by noisy gears because the motor case is low on grease.
It should have high temperature grease available from some Home Depot & Hardware stores
In my case the bearing seal was bad, So see my fix and videos here.

Quadra-Fire CB1200 Classic Bay auger feed motor grinding noise?

Hello Stove works fine but every time the pellets drop and the pellet feed auger turns, there is a loud grinding noise? See this noisy video - turn your sound up. After replacing the auger feed motor, when the pellets drop it is very quiet. :) See quiet video - turn your sound up. When the...

Red and tacky is the wrong grease for this, you want something similar to a white grease that is thin enough to flow into the gears and not pile up on top of them and stay their.. Their was a post a few month ago about this..

White lithium grease is also not right. Open up any stock auger motor and you will not see any white grease?
No white grease was used here.

what ever he is using in that video is not a high pressure grease and is definitely not red and tacky.. Putting a high pressure grease in will just sit on top of the gears and after a while nothing will even be in the gears..

This grease looks even better but more expensive. I may get this next time!
