Is it loose and whooped Don?

My Englander was so sloppy it wouod spin well if you held the motor body at a certain angle, and would hardly spin if in another position.

The motor casing is vibrating and I cannot just crimp it harder like the room blower in the US Stove 5660

 

[TheMightyMoe]

Have you disassembled the motor from the blower cage and tried tightening the body/casing screws? (If it has them) Also depending on room/stripping, you can use nuts on the motor/casing screws

I do not see any body casing screws. Looks like it was riveted somehow. I will check more.

I was thinking about putting a 3" radiator clamp around the housing because when I hold it, it stops vibrating! Do you think that would work?

Thanks

That A082 is what I bought for my Englander from CSH, did it come with the housing?
Did it come with a 6" Lytherm Gasket?

Did you have to remove the housing?

CSH seems to be the cheapest price?

That is what I need for the Lopi Pioneer, Quadrafire Santa Fe and my friends Enviro EF2 !

Thanks
Don

Yep, came with everything.. Motor, housing, impeller. A082

 

[TheMightyMoe]

If the housing is just loose, that might work in short term, could even last a long time. You really can't know, unless you take it apart and look at brushes, windings, etc... It does look like it needs replacement, if it doesnt have bolts, usually they are not meant to be rebuilt.

No screws or bolts for the motor casing. I tried lubricating, cleaning and banging on the crimps with the hammer and screwdriver. It quieted down some but still noisey. Looks like I will go for a new one.

Hi Dexter
I talked to the guy at CSH. He said just the motor and impeller would cost almost the same with the quantity they buy from Fasco. So they only offer it as shown below!

This is called the Generic Fasco Wood Pellet Stove Generic Replacement but this blower is almost identical to the Quad 1000 large exhaust blower!

Still the best deal at $90.65

Make sure the fan isn't out of balance. My Croix vibrated and rattled like mad, until I balanced the fan. It is an aftermarket fan without the rubber bushings (read: cheap). Balancing it made a world of difference. I never could get the crimps to hold for long, since the vibration just pounded them out again. What did help a lot at the time was to connect a fairly strong spring between the motor housing and the stove, at right angles to the motor shaft. It didn't stop the vibration, but it did silence the accursed rattling.
The real cure, however, was balancing the fan.

How did you balance the fan?

Very nice
Great info and good pics too!

I ordered a new combustion blower, since it looks like it may be the original and that would make it 15 years old.
I still may try a radiator clamp just to see if it resolves the problem before the new motor comes in.

Hello

Well I tried the radiator clamp trick to quiet the Fasco Motor Case Noise from vibration.

Does it sound better?
You can hear it here

How bout you just tell me, so I don't have to watch the videos.

 

[Don2222]

How bout you just tell me, so I don't have to watch the videos.

Ok

I just added 2 strips 1/8" thick of High Temperature 525 Deg F Orange Silicon Rubber under the radiator clamps to absord the rest of the vibration and noise!. Now the vibration is just about completely gone! I tried it with one clamp but 2 is really needed here!

So for the people who DO like to watch videos here is the Final Part 3 with the good fix!

Hello

Got new A082 Combustion Blower and More Problems!

I thought this would be straight forward but Oh NO !

I removed the Fasco Generic Wood Pellet Stove Motor Replacement and Impeller from the housing. Ok, not too hard just an allen wrench. Then removed the 3 motor mounting nuts with my socket set.
Specs on this motor seem to match up very well with the original specs shown in 1st post
No. 70218293 Type U21B
115V 50/60HZ Class B Type A 0 CFM 70
0.95A 3000 RPM 1/70 HP Max Ambient 40 Deg C
Model A082
LR36496 M4811


No mounting plate for stove. Ok. I cut the shaft off the old motor and removed the mounting plate. Those old manual Hack Saws still come in handy!
See Pic 1 below.

New motor is not shock mounted like the old motor. Ok, neither is the one on ebay for $188.00 ! ! !

I went to put motor on old plate. Does not fit! Holes in new motor are a tad too close to the motor case!

Should I do some drilling?
Make a larger diameter hole?
or
Try to elongate the hole?

See pic 2 -5 Below

 

[DexterDay]

My AO82 mounted rights up..... No drilling, sawing, etc... If that was the listed part, it should have bolted right up?

 

[heat seeker]

1) Verify you got the correct motor that you ordered.

2) I'd drill new holes, and block the old ones with short bolts and nuts, unless minor filing would let the motor fit. That way, you could always go back to an OEM motor; i.e. not burning your bridges.

Thanks for the Info. Did you use the housing too?

It is the right motor, but I cannot drill NEW holes, no place to drill them. The holes are so close to the bolts, the only way is to enlarge them.

The holes are in the motor so I can always go back to the OEM one.

Yep.... Part # for my old Englander (circa 96) matched uo to the A082. Used housing and everything. Put a new gasket on and she was running like a Champ!

Wow, that is nice! I am checking my alternatives, but if I have to ream out the holes a bit to keep from paying more than double, I will do it. This motor does have all the right specs!

 

[smwilliamson]

All you needed to do was hammer the crimps on the casing to stop the vibrating. Yes? Whats with all the clamping? Where the black meets the zinc is where your problem is.
