"we ran it until...."

Carrier gas furnace

[amd]

What am I looking at?

[ZiLLaCooL]

Looks like a blower shaft,were they freakin deaf!!!! If they weren't,they are now.....LMAO

[dandyme]

never have understood how the shaft and bearing get that bad.............

and customer claim to have not heard it until recently.............MBFA

[Some Dude]

You dont see that much anymore. Most new crap breaks before it ever gets that bad.

[Lurch77]

You caught it early. Did a Carrier RTU recently, a twin squirrel cage blower. Outside bearing seized, shaft ground away, bearing bracket broke, flailing parts destroyed everything in the blower compartment. The customer saved money by canceling the mid summer PM, where someone would have seen the problem before it got that bad.

Was that out of a residential furnace? Didn't think any of them where around anymore.

[pacnw]

correct on the blower wheel shaft.

yes, out of a residential unit.

[Milk man]

Do you remember the model number?

[pacnw]

Do you remember the model number?

58GA-100-A-1

[no_klu]

I think i'll show these pictures to my customers that don't want to pay for annual maintenance.

[Milk man]

58GA. Those where the days. It was out of date even before I started doing this stuff. I've rebuilt a few of those blowers. I remember a bearing kit. It was in an orange tool box and at one time fully stocked with bearings, shafts, locking collars, and other stuff needed to do it in the field. I'd just bring it back to the shop to use the work bench.

My boss bought out a vendor's supply of bearings and shafts once. I couldn't believe he did that. No one wanted to repair those furnaces and they should have been replaced when the blower went bad.

We started replacing worn out furnaces once we learned to water test heat exchangers.

Had the same thing happen to me (same model of unit it sounds also)..with a few exceptions. We did do a quarterly PM, but the manager kept saying no don't repair it now, lets wait till next time. I made sure to document what he said and i saw. After the failure he wanted to see the damage, sighed and gave us the go ahead for a new unit. It already had a bad second stage compressor that he did not want to fix.

Too funny, I sold a customer a Thermopride Oil Furnace in 1998 that was belt drive. He is on his 5th set of shaft & bearings, why?

Because he is a mechanic at a Ford Dealership, he absolutely insists that he do his own maintenance.

He tightens the frigging belt up like it's an alternator, I can't get him to see the light.

Oh yea, he has also fried a motor too!

[swamptiger]

Ha had one just like it this week always have wondered how the noise didn't catch the attention of the customer to think hey something might not be right here before it could progress to is point.

[Texas-Tech]

did you try some oil first?
