These pictures are NOT of my fan, but the exact same model!


Patton Fan Mdl A0424B2079, E6278818 in, riveted blue blades ca '75, puzzling intermittent grinding rotor/bearing,but spins freely.

There is a total 3/16 in forward play in the rotor when moved by hand, & I see some [but less?] play when starting.]
I know this is a lot of play & I don't remember seeing this before.There is no side to side or up/down play.

I have used & loved this fan for years! I hate to admit that in the last 2-3 years I began using Kroil to lube the front port because it was so difficult to get to. I now have figured out how to remove/replace the grill.
I also used PBlaster once, [maybe this was just before the problem started ].

My question is: Why does the fan intermittently, start & run fine; but at other times when it starts: it binds/grinds,runs a little,then binds again & the fan even jumps: as a reaction from the force of the motor pushing against a blade that's suddenly started binding?

The stuff you were using to "oil" your motor with is NOT lubricant but stuff used to break free seized/rusted bolts and screws (I can't remember what its called specifically) but what you should be using is 3-in-1 in the blue can or Zoom! Spout Turbine Oil to lubricate the bearings on your fan, that might be why your fan is messing up because your bearings are dry (since you didn't use actual oil to lubricate the motor). As for the front to back play you were experiencing, some front to back play is normal, if it gets too excessive then you have some problems (some of the fibre washers used for shimming the rotor are missing or broke and need to be replaced). 
Get some 3-in-1 in the blue can,  or Zoom! Spout Turbine Oil relubricate the fan's bearings and then see what the fan does, and let me know what happens.

Yo Roark,

That's an interesting Patton you've got.  It's old enough to have a large shaded pole motor (no capacitors), but modern enough for the sickle blades and multi-prong tension guard.  The one I have uses the big paddle blades and 4-prong tension guard with a 1/6 HP General Electric motor!


I'm gonna level with you; I'd highly recommend taking that thing apart and doing a full detail clean and lube.  I'm really pleased to hear that there wasn't any up/down play.  Usually rotor grind/growling goes hand in hand with vertical wear, when the rotor scrapes the stator.  I'd also say go ahead and grab some fiber washers to help seat the rotor.


Whether or not you do a full tear down, please do as Levi said and show that thing some love using Zoom Spout or 3-in-1 (blue/white can ONLY).  The stuff you were using before wasn't intended for continuous duty.  Hopefully no bearing damage has happened since then.  Those Pattons are surprisingly tough and one of my all-time favorite brands.  Enjoy and let me know if I can help futher!


-Mr. T

Three days ago: I used about 10 drops of 5w20 motor oil in each of the front & back ports, but the problem still returns intermittently.  

Shouldn't that have been enough lubrication?    

[I just found out that the detergent in motor oil is bad for fans. ]

You might just have some sludge/gunk buildup as a by-product of the other stuff used before + years of running without cleaning or service.  It's hard to know without cracking open the motor.  I had one similar to yours years ago with a similar issue with sluggish operation.  I oiled it, but still ended up tearing it down (broken down oil, dust, etc), then it ran smooth as silk.

I definitely will take both of your advice  & use Zoom Spout or 3-in-1 (blue)! 

And I will rebuild the fan if needed.

I agree that the fluids used previously have contaminated the lubrication systems and needs to be cleaned. This will also allow inspection of the bearings and rotor shafts for wear/ play and the addition of fiber washers. It probably can be done in an hour or two and will increase the longevity of your fan. If there are felt oil wicks at the bearing housings, they should be cleaned or replaced. These lubrication systems are prone to clogging and gumming up over time. Good luck and welcome to the forum.

Where's a good [cheap] place to buy Zoom Spout?

If the bearing, stator, sleeve is damaged: how expensive [& difficult] is it to find replacements?


I've seen 
only 1 or 2  rebuild/clean/lube videos on Youtube,which weren't that good. Do you recommend any instructions or videos for my model?

The only places you can get Zoom! Spout oil is at Lowes, Menards, Home Depot, Ace Hardware or True Value Hardware stores no one else carries it except if you chose to go the online route then Amazon would be the place to go, but Zoom! Spout oil is not cheap to begin with it's about $8 a bottle but that bottle will last you more than a couple years if you don't over use it, or use it for other purposes other than oiling fans.

Yes but unfortunately not everyone has an HVAC parts supply house near them Mr. Block! So the next best place is the local hardware store which unfortunately charges $8 for a bottle of Zoom! Spout.

And apparently you don't have Google. I found 2 appliance parts stores near you.

For what it's worth, I always get my Zoom Spout from Westlake Ace Hardware.  Nowhere near $8 last I checked.
