Article [13] ST1300 - Rear Flange Bearing Replacement

[Badger]

I purchased a hankook ventus v4 for rear and i took the avon storm 2 out. The rimb has lots of rusting (iron rusts went through the aluminum on the edge lips) so I decided to powder coat. I have to take the bearings on the wheel (not on the flange) since they are changed 20k miles ago. One bearing is 10 bucks which is ok but the other one is 42 $.
Motorcycle is a frustrating expensive thing. Cars don't have these kinds of annoying deals.... Sad to say.
I have a bearing puller by harbor freight already but the diameter is too small and there is this damn spacer there... It leaves only one option which is hammering... I don't like to use any bearing after hammering... Grrrrrrrrr.......
Bearing # 19 is 16$ but the bearing # 20 is 44$ which makes me sad

Change my rear tire today, check flang bearing is bad on one of two. Wondering if anyone used after market single seal bearing on this drivehop, if so. Do you have part number? I'm thinking single bearing might be much better then two? Though my got bad after 90+k miles.

 

[TipSTer]

OK, I found VXB bearing NA4905UU Needle bearing is it good as single twin balls CBR bearing? It's much cheaper then CBR bearing though $9.95 vs $44.00. Any tips?

Looks like it is sealed on both sides. As long as the dimensions are the same you should be good to go with it.

When interchanging bearings remember that dimensions are not the only thing to go by. Bearings can have different rated working load limits, different heat ratings (tolerances in the bearing typically decide this), different speed ratings (bearing for an analog gauge needle won't have the same rating as a dental drill), and more. For some uses these ratings won't matter much, but for a wheel bearing, I stick with something from a known company which has researched this data for the bearings they are selling.

I worked 10 years in the precision bearing industry before moving to the automotive field.

Maybe someone should have said this to the guy that speced out the flange bearings on the 1300..

This is a pretty common problem on the ST1300, We had to start stocking these bearings because of the amount of problems we see with them on a regular basis, definately need to be checked on every rear tire change,

I have a few on hand as well for this reason.

been there, done that, got the t-shirt...
and for the new people that haven't seen the inner race when the bearing feels 'gritty"

Thanks for De Tips Sennister can't wait to installing needle bearing type on my wheel's flange. Tom Mac 04a that is what my OEM looks like also missing few balls on one de twin bearings, though I my bike just turning over 90K Miles. After reading this forum, most people had their flange bearing gone bad lots lower mileages then me. Will see how this made in China for $9.95 bearing will holing up?

HR Cole & I changed his ST1300 front & rear wheel bearings with the kit from CBR Bearings. The kit included the all the seals and the two o-rings for the rear wheel & the flange bearing (needle type). They do supply very quality bearings, and they know what you need, just tell them what bike you have, and they will get them right out to you.

Harry can correct me if I'm wrong, but the original bearings that we pulled out had over 97,000 miles on them, and they were still good. We changed them anyway. We used this blind bearing puller from harbor freight,



The only real trouble I had was being unfamiliar with this tool, as it was the first time I had ever used one like it. Now that I have added this puller to the tool box, I'm ready to do the next one.

Can you please help me with an advice please.
I have this problem looks like the bearing problem exactly but not in the bearings.
I have same eaten up look at the flange bearing opposite site where the o ring (on the rear wheel) sits in the inner race of the flange. It looks like o ring smeared all over but after wire brushing i can see the little hole looking recesses. The 2 metal shouldn't touch each other and the inner race is a very hard metal so i don't have any clue how this happened. Here some pictures, of the flange.

Now there is no marking on the wheel side. So i dont know how these happened. O ring was flattened and there was molly leak present.
I am thinking to sand/polish it. i hope i dont change the diameter too much. I dont want the o ring to be out of diameter.
Part is expensive so I dont whant to pay 180$.
What do you guys think about this thing?

 

[BakerBoy]

Sorry Badger, I'm at a loss as to what part you're showing and where the problem is on it. :

Re: ST1300 Rear Flange Bearing Replacement

Sorry, let me try to explain with my broken English,

http://www.motosport.com/motorcycle/oem-parts/HONDA/2004/ST1300/REAR-WHEEL

On this site, the part 7 goes to the rear wheel. Part 7 inner cup goes to rear wheel and rear wheel has a grove where the o ring (part 22) goes on. That o ring is going inside the part 7 which is the flange inner cup, which i provided in the pictures. Ooooo maaan, even i am confused now...

 

[BakerBoy]

Thanks Badger... I'm familiar with all the parts shown in the fiche, but the pictures you posted do not show part #7 (unless you disassembled it further than is common). Did you remove the 4 bolts that hold part #7 together? Were the bolts loose? If they weren't loose, I'm not sure how the 'inside' face of the part in your pictures got any wear on it.

 

[Badger]

Yea i took those out. Was too tight i used impact wrench.

 

[TipSTer]

Folks, Tips from Tip. I installed this VXB bearing NA4905UU Needle bearing a month back got over 3000miles it gone bad on me, cheap $9.95 bearing didn't lest long for me. Will try CBR bearing next....

 

[BakerBoy]

TipSTer, how big were the needles as compared to the balls of the OEM bearing?

 

[TipSTer]

I didn't measure the needles bearing before installed, but compare to balls bearing its much smaller diameter then balls bearing...
