R6 Wheels and USD Forks ' 85 FJ 1100 " Upgrade

[giantkiller]

Hey dreadrock I was just looking back through this. I see the 750s lower yoke is dropped. How much is it dropped? And what's the size of outside of forks. I was going to use newer big piston forks but the bottom tapered off too soon to drop them down far enough.
maybe the dropped 750 lower would allow that

Thanks Dan

 I'm at work ( bored slow day ) but ill get the Measurements this weekend when I'm out in the shop this weekend !
Been sitting here thinking about your guys Answers and I think I might be Explaining things wrong ! On the rear wheel with the sprocket carrier off there's the inner bearing . Which is the one in the pic on page 5 , if you look there's the old bearings parts and a real thin Miss shaped part ! That's what I'm talking about and when its on the spacer tube between the bearing to help keep it centered when putting the bearings in . It's a lose fit so when you remove the bearings you can move it just a lil bit to catch the Edge of the bearing ! I've replaced bearings on other bikes and they didn't have something like this . You would get one bearing in , flip wheel over place spacer tube in wheel , then press bearing in to Squeeze the tube between the two bearings !
  The front wheel has the same thing just smaller and when I was installing the front bearing was looking and all it seemed to do was keep the tube centered to make it easier .

If I sound crazy dont worry most people think I am LOL ill get some pics up this weekend to help Explain !

The problem is the spacer tube between the bearing is ok but the thin centering Collar got messed up removing the rusted bearing .

Above is what confused me.  You talk about the spacer tube.  Are you saying that the rusty thing shown at the bottom of the second picture was used to keep the spacer tube centered in the hub?  If so, I've never seen one before.

I press one bearing in, install the spacer, insert the axle (or a suitable rod to hold everything in alignment) and install the second bearing.

#2 and 3 are it ! Sorry really guys I'm on my phone and not my laptop !

That's how I've always done it that's why I'm not sure if it just to help or really needed !

I would not chance it. Get a new collar. That wheel assembly is designed a certain way. Follow the oem design.

Yes, you can center the axle tube by using the axle while installing the 2nd bearing...but...

Consider this: That centering collar, as thin as it appears, *might* be necessary for the assembly to get the correct width to properly distribute the compression force to the inner race of the wheel bearings (when you torque down the axle nut)
Without that thin collar added to the width of the axle tube, you *could* be putting too much lateral force on the bearings when things are torqued down. Similar to having a axle tube that is too short.

Note: *might and could* are used because without careful measurements, I'm not sure. Just my hunch.

Again, be safe, follow the oem design.

#2 and 3 are it ! Sorry really guys I'm on my phone and not my laptop !

I hate to drag this out but; HUH?  #2 and 3 are a bearing and oil seal

[DreadRock]

If you look lil closer # 2 is befor the bearing and on the list is called a " Flange spacer" I could be wrong but same thing on two diff Schematics I've looked at ! And never a bad thing as I see it as learning LOL

Question : we are talking about the stock FJ1100 wheel and not the R6 right ? When I got home looked in my manual and they don't show it there  but I know it is

It is on the '84 FJ 'fische, but not the '04 R6.

LOL ok let's forget the R6 wheel , should of keep my mouth shut till I figured this out LOL

  Yes the Flange spacer is in both fische for FJ1100 rear wheel  I looked at speed&sport and the site above . But when looking in the FJ manual its not there ! Odd

[Pat Conlon]

DR: Does the bearing spacer tube (#6) fit inside the collar? So that the spacer tube extends from inner bearing race to inner bearing race?

If so, I would not worry about it....that is...until you pull your axle out and the spacer tube falls inside the wheel.

Sorry, my bad.  I was looking at the R6 wheel link.  I see it on the FJ schematic.  Move on.....

[DreadRock]

LOL all good sir ! I always seem to have a hard time explaining thing 

  Will be rebuild the forks today and anyone know the Amount of fork oil all the manual real says is use 10wt or 10/30w but not how much ?
