Where can I buy the bearings ,thanks

That is NOT a Whirlybird!

Thanks mate, very helpful.

Is it from Ventlite Roof Ventilators? Somehow I think that brand went down. Only that brand has fans below their vent.

Did my whirlybird today that was making an awful screeching noise. The 608RS bearings were definitely the go for mine (12 years old). One bearing had completely came apart. I didn't need to use vice or multi-grips on the shaft, i just used two 13mm spanners simultaneously on the top and bottom nuts to unlock the bottom locknut. Used a flathead screwdriver to wedge out the old bearings, that worked well. All in all, very easy to swap out the bearings, thanks for your vid :)

Great post thanks

an entire whirlybird with roof jack is $52 at Home Depot

How did you figure out the model number of your bearings great video

brands in Australia . Oz vent , Ampilair , wind master , big bird , abey , hurricane , plus about 4 others imported from america .

be careful with the location tabs on the ends of tte 4 plastic arms . they snap off easily .

I hate when they start squawking.

Some advice from someone who got caught buying the wrong bearings. I bought the 6200 bearings when in fact I should have bought the smaller 608 z , so it pays to have a look first. Video applies to quite old models. In the above case they are 30 year old whirlybirds.

what does this fan do exactly? i know it spins but does it help with the exhaust of the smoke or not?

Hi Champ, great video, where did you get the bearings from???

where did you buy the bearings from please. Great video.

I wanted to know how to take the thing off and reinstalled which wasn't shown, I ended up removing the wrong screws

6200zz are steel non contact seal bearings . 6200 RS are rubber seal full contact seal bearings . The RS type will be a little tighter spinning than the ZZ type . Rs will last a lot longer .

That ventilator is a Big Bird brand ventilator made by Erten Products Australia . When you reassemble the bearings to shaft assembly apply some paint any paint will do to the shaft axle where the bearings ride . This will take up the slight difference.

I had the same problem but I sprayed WD-40 and the problem was fix. It has been 2 months since I spray it and still working as new. Thanks WD-40!!!

You have a Monet tile roof like do, really dont need a vent as the tiles let the heat through at the arches. Im in Texas where summers are 110+ outside & the attic is 130+F

there is somthing else in your roof at the end like testing air destenation , what was that!!!

Im sure you can build it too guys. Just look for InpliX page click the PIG and build it too

I think the fan should go the other way around to maximize the amount of air to be pushed upward.

My turbines don't have a prop like that on the underside. I wonder why ,,,

Hi Sam Not sure what the brand is as there are no markings on the ventilator. In Australia the main brands are Windmaster or Apelair and they are around 30 years old.

Note that the Spin Test should be around 14 Seconds. If you can get it to spin for around this long then the bearings are good :-)
