Wheel Bearing part # help

I installed new front wheel bearings on my 72 TR6 about a year ago, I had them in my parts stock from years of accumulating parts and I know they are Japanese no brand. I have adjusted them several times now but something tells me that you should not need to re-adjust them more than once after installing them, I went 10lbs and off one flat (free spinning).
Can someone please help me by giving me the correct part #'s that I need to buy them from one of the majors such as SKF, TIMKEN, etc. along with the rawhide seals rather than the felts.
I want to go with the best quality available...Just hate to do something twice!

Thanks
 
Mike: the Chicago Rawhide P/N I have for the seals is CR #13612.

I don't have P/N's for the bearings; I'm sure someone else will jump in. If it were me, I'd just take the old ones to a bearing house and have them give you the equivalent SKF, etc.

Tom:
Thank you so much, I wanted to get a head start and not have to remove the ones I have on now, but the rawhide seal # alone is great! Thanks.
 
Does this help?

Seal (Inner) 480991
Cone (Inner) 07100S
Cup (Inner) 07210X
Cone (Outer) 03062
Cup (Outer) 03162

Did you also install a new felt seal at the same time ? They are frequently too thick when they are new; leading to false bearing clearance readings. The factory-recommended procedure was to set the bearing clearance before installing the seal, then mark the position of the nut; install the seal, and return the nut to the marked position.

Also, changing clearance can result if the races were not firmly seated in the hub recesses.
 
Thank You, Frank and Randall:

Yes the #'s are what I needed and yes I did replaced the felt seal and fist soaked it in oil, what I'm in doubt about is the quality of the bearing itself somehow I believe it has caused a sort of vibration that resolves itself when I go back and adjust the bearings again...that can't be right.

Thanks for your help.
 
Could be, but the best bearing in the world won't control the hub if the clearance is too large. With the too-thick felt in place, what happens is that the hub pulls up against the felt instead of against the bearing, leaving the bearing clearance huge. As soon as you start to drive the car, the friction and weight of the car begin to compress the felt more, allowing the hub to become loose again.
 
Thanks Randall:

Maybe I should try fitting either a new seal or looking for the one I took off and trying it back on?
 
Either one would work (I believe the P/N that Frank gave is for a lip-type seal that doesn't have the problem); or you could follow the (factory) procedure I outlined above.
 
I just picked up a pair of the # 480991 seals listed by Frank. They were about $8 ea. vs $20 ea for the Chicago Rawhide.
When I gave them a quick test fit, I found that the OD is slightly smaller than that of the original felt seals, and they drop right into place as opposed to being a press fit for the originals. I haven't measured it yet, but I'd guess at least 0.010" smaller than the ID of the hub.
Assuming that the rubber inner lip seals OK, I'm still concerned that grease may find its way around the outer edge of the seal and onto the brake rotor.

Anyone have any thoughts on this?

TIA,
Tom

P.S. Frank, please understand that I'm not disputing your info. I know you got it off the Timken web site.
 
Hi Tom:

Have you been using the rawhide seal yourself in the past? and how was the fit?.
regarding the cost $16.vs $40., if they are going to be there for years as the last set I had on, that would be OK. Please jump in and and leave your feedback, I have not gone out to look for bearings or seals yet.
 
Sorry, Mike. No experience with the CR seals. I have the felt seals now, and was hoping to install better ones.And I agree about the price; just didn't know of any difference. I may just order the CR seals.
BTW, I measured them this AM, and the Timken (actually Federal Mogul) seals are
0.020" smaller OD than the felt seals.

I'd hope that someone with experience with the CR seals would chime in here.

Tom
 
I'm likewise no help. Replacing the original felt seals once in 40 years seemed reasonable to me ... wasn't broke so I didn't fix it!
