    Hi Guys,

    After I did some long hot burns with my Okie gold I noticed the combustion blower motor was getting noisy. Over the course of the last week or so, the few times it has been on to remove the chill from the air, I noticed it wasn't getting better. Down right annoying. So tonight I replaced it with my spare. Good news is it is back to being super quiet once again. I think the softer rubber mounting bushings have a lot to do with it but in any event...

    So I have this original motor I want to replace the bearings on. The front bearing feels dry so pretty confident that is where the noise is. It's been a while since I have been out shopping for bearings and I no longer have pullers either. So I am out of touch with good names and such. Hoping you can recommend some good replacements and sources for me. Would it make sense to put high temp bearing in replace??

    ::I tried to post a pic but the upload file does nothing. Will try after creating thread.::

    Thanks.

    I see one word that I'd not like to see on any bearing. I prefer Japan and IIRC the RBC 608RS or 608SS will out last the PEER POS's.

    There is a set screw hiding amongst those fins.

    You want german or jap bearings,and not cheap ones.Posted a lot of info on this on "the other forum" last year.Skateboard bearings are now(have been for some years)oil filled,and you need hi temp grease filled bearings.You probably will need no puller tools for these motors.Last year I bought a dozen german bearings off ebay,good quality,BUT very fragile,ruined one pushing it in by hand with a socket as a driver,spun motor,did not like feeling in hand,redid with another,has been running in basement on and off for 2 months.Buy more than you need.I think you will find that the type of seal is irrelevant,as the outside fan.which serves as the seal for the shaft,never gets aboue 200 degrees.

    Will give you a little old mechanics heads up,when yo take off the impeller,clean the shaft and inside of the impeller(scotchbrite pad works well),take screw out of impeller, coat shaft,screw hole and set screw with nickle antiseize,will come apart much easier,even with high temps.

    Yup good advice. Did quite a lot work with motors that were in a somewhat harsh environment in my younger years and that was usually par for the course. It pays in spades.
