Rear Needle bearing discontinued!!!

[prometheus578]

"The mighty Casey has struck out."

Stopped at Yamaha to check the rumors.
Still in the parts fiche.. but whoops, none in the warehouse. Discontinued.
Told 'em to order me one anyway.... see what happens... if it arrives next week.
Price was now forty something bucks...
I had bought three last year for $33.

Don't even think about it... I hoard.
(Yes, TRBIG... it sounds the same, but the meaning is different)

When I ordered a set of stock handlebars for my restored bike it took a while to get them because they came from Japan but they did arrive in time. That bearing "may" still be available from the manufacture because they "may" have found another use for it across any given number of machines they make bearings for.
It will be interesting to see if the one you ordered arrives.

So that's what 'unobtainuim' looks like

rman, it looks like you have stumbled onto something. At that price. It would behoove us to buy a spare for each bike in our stable.

Anyone tried out that bearing from WBDS listed in the post above?

Anyone checked into it? I sent an email and am waiting to hopefully hear back.

Think about this. Mention has been made about using this bearing with a spacer. You will need TWO spacers, one for the center on the axle and one for the outside dimension of the bearing.

I suppose these spacers could be made from the carcass of the old bearing?

"I've lost my bearing."

What concerns me about that bearing, at least from the pic... It's not a sealed bearing...
Plus, theres no inner "sleeve"/collar?
Looks more like a bearing that needs to be surrounded, or bathed in the lubricant... not one that sort of stands alone on an axle.
Odd... haven't had a phone call from Yamama concerning my order.
Might need to stop in there and see what the deal is.
Sadly... I'm forced to leave the house today... need to go to the part's store. Blew an axle grease seal on the truck.
(No big deal... rear brakes haven't worked for years... but now there's this growing oil stain on the driveway.)
Glad it's cloudy out... bright sunshine makes trips outside more miserable for me. (Hard for me to hide in the shadows, and all.)

On the palm of his hand

Hi Prom,
the bearing shown on mrfiznix' hand is a Drawn Cup Roller Bearing. The outer case (the drawn cup) relies on being pressed into a cylindrical housing to keep it's shape under load. The rollers run on a hardened & ground sleeve that the Mfr also sells or directly onto a hardened & ground shaft. Torrington and INA are the big names in this style of bearing. As the Yamaha bearing seems to be no longer available and is apparently a non-standard size, a search of Mfrs catalogs to find the nearest best fit amongst the stock bearing sizes is the best way to go. Then go to "Bro with lathe" to get whatever size of sleeve or spacer that's needed to make up the difference.

Thanks, Fred.

This bearing looks to be the correct size, not the one that takes two smaller bearings and a spacer.

Those thoughts about it being an open bearing, etc are good ones.

paintman, you are the man if you can find a match. I can't pull mine to take in for comparison, out of fear I'll ruin it like I did the right side bearing. Just cleaning and re packing it while on the wheel will suffice for me, it is in great shape.

"I was sadly misshapen."

Somehow, had another bearing in mind.
Have a whole drawer of used bearings that I used to press new ones in with.
Big honking bearing... thought that was the one in question.

Just got back from Yamaha... no luck there.
Even got on the phone with the "All Balls" people.
Got confusing.
They had a Yamaha bearing kit...they said wheel... for about $37.30, so things looked promising(based on the price). Then... the specs were all wrong.
As for my earlier post... disregard what I wrote, as most of you do, anyway.
Yeah, Fred, you're right.
I found my spare bearing... has a removeable inner sleeve, etc.
I had forgotten what these things looked like.

That link that Mrfiznix posted looks like the deal. Same measurements, etc.
Ok, who's gonna buy one and test?

[Bonz]

Yes, who's going to give it a try? Preferably someone who has no other option, things seem to work best that way! My bearing is still in good shape and re-packed in the wheel, so I am NOT TOUCHING IT!

I ordered from wbds.com and got it today, but it is slightly different. There is 3/4 of it needle bearing and 1/4 ball bearing. Any problems foreseeable like this? Oh, the bearing in my earlier post in my hand had the inner race taken out, I just left it out to see the inner needle bearings easier. The bearing in this picture has the inner race, I took it out for a couple pix and put it in for one. At wbds.com they said the bearing I ordered wasn't in stock, but they could ship a INA branded one. I said great! because I thought it would match up exactly with the old one that was an INA branded 5904

mrfiznix;

The I.D. of the inner sleeve is 20mm?
