83 XJ750 Maxim Wheel Bearing Sizes

Hi, just curious if anybody knows the sized of the front and rear wheel bearings? I have a friend in the bearing distribution business and he said just let him know the sizes and he will send them to me.

For the steering head I have (tapered roller)

Upper: 25 x 48 x 15.2
Lower: 30 x 48 x 15

If anybody knows the wheel bearing sizes (front and rear) it would be much appreciated.

Thanks,

Andrew

 

Don't know the sizes but these numbers should get you the right ones
Front 6302 2RS .. 2 of. Rear Left 6203 2RS Right 6303 2RS

Those are sealed bearings, in fact if you google those numbers you'll find sizes and options, sealed or not.

Let us know if you can get the tapered rollers for the steering head from the sizes you have and what their part # / code is. I couldn't.

 

Thanks,

Here is what I found. He send to just send him the sizes and he will take care of everything. He is a bearing importer and deals with pretty much all the major companies (SKF, FAG, Timken, etc.)

I know this is an old post but hoping someone can help. Wanting to replace my '83 XJ750K front and rear wheel bearings and the numbers I can get off the bearings are only on the rear, nothing from the front.

Rear, 6303 RS Koyo
Rear, 6203 LU NTN

The post above shows three different bearings with slightly different numbers and I only see the two. What qty do I need ? Attached are a couple of pictures. I am assuming the MHSA 22 42 (or 48 can't tell) 7 is an oil seal. Are there any oil seals for the rear? What brand of bearing would anyone recommend? I heard Timken, SKF and NTN were some of the best. Any thoughts?

Thank you,
Joe

+1 what @XJ550H said - save yourself a lot of hassle and contact @chacal via PM or send email to info@xj4ever.com.

There are 3 bearings in the rear wheel, a larger bearing on one side, and then two smaller ones that sit side-by-side on the other side.
