VF500 F2 Rear Wheel Impossible!

Per those pictures I can tell that it's a sprocket carrier that I machined so it is correct. Are you following the installation instructions I e-mailed you yesterday? They should give you everything you need.

From the pictures it looks ok to me. You should have to squeeze the largest spacer (far right side) in last. Obviously these exact parts fit just fine on Pat's bike so you should be able to get it together!

 

If the parts are correct then there has to be something else wrong.

I spent 2 days on this install and with the Chain Adjusters there isn't enough space. I can't even see all the axle threads through the end of the swing arm with everything on.

Is it possible through heat or wear the the spacers or bracket or something could have changed shape/size?

...and could it be possible that my swing arm is somehow narrower?

 

I stand corrected on what gets machined. I haven't actually done the mod yet so this is good information for me. I am aware that it is supposed to be a VF500F Drive though.

I'm thinking the swing arms on the Canadian bikes might be different than the American bikes. Anybody have a fiche for the Canadian bikes we can compare to?

Or the Swing Arm has been modified/Damaged in some way.

 

If that's the case then I would assume someone also screwed with your axle and spacers since they seem to fit fine.

The old stuff came out fine...Just removed the Nut....tapped the Axle out with a mallet and pulled 'n' twisted the axle out the rest of the way

 

Looks like a stock 500 carrier hub to me? Doesn't look modified. The caliper bracket looks like yours, yes, the hub, no. Don't you normally get people to use the CBR hub?

 

first thing that tells me that its been machined is it has bolts instead of studs.

 

take a look at a stock vf500 carrier hub and then say that slowbird's doesn't look modified....

it's straight from jaime and all this fit on my bike fine. it was tight but it fit.

 

No, not for the 500. It's 100% for sure a sprocket carrier that I modified.

As Pat mentioned, it fit just fine on his bike. Normally when guys are having issues with the install of the wheel swap kits it's either because 1) they have spacers in the wrong place or 2) they are trying to install parts that don't belong.

With as many of these kits as I've made I've had to deal with a few bikes that are stubborn. It always works out in the end.

Just to clarify - the axle assembles from left to right, not as described above.

 

Are you sure that the sprocket carrier is pushed into the wheel all the way? There should be a small gap where you can see into the cush drive rubbers - that is ok. You might try a couple of swift blows with a rubber mallet just to make sure it's fully seated.

 

That just means the studs were taken out. I did the same thing on mine! I'm using this to install a 900RR rear on my 86 700.

I pulled the studs and had it painted - the thing that tells me that slowbirds HASN'T been machined, is that the edges of the stud holes are still chamfered.



Looks the same to me?

 

Only wrote it that way as it's easier to slide the stuff onto the right side if the axle is being inserted from the right... opposite for the left side, for the purpose of checking parts alignment. :thumbsup:

 

Here's how the hub should fit:


With bolts and sprocket installed:


***Notice that on my non-machined STOCK OEM hub, the sprocket sits flush with the top of the 5 shoulders that it mounts to. Just like slowbirds! The hub/carrier has NOT been machined, it's merely been modified by having the studs removed, which anyone can do with a pair of vice grips!***

 

That bothers me. You are using your axle, which was in your bike before? (I assume yes?)

 

slowbird take a look at your stock carrier and then compare it to the one you got from me. If the sprocket carrier hasn't been machined then it wouldn't have worked on my bike because the chain would have been out of alignment.

How did i put that on my 500 and ride it without problems - SEBSPEED - if the sprocket carrier was not machined? It has been machined. I sent it in to be machined. It got machined and it worked. Like I said before.. look at a stock 500 carrier and then compare it to the MACHINED one.

SLOWBIRD - Please post pictures of your stock 500 carrier for a reference

 

Mine sits like this:



Not nearly this tight:



If I can get that little Extra space out of the Hub I MIGHT be able to squeeze in the chain adjusters. I've tried tapping it so it sits tighter but maybe I should stop being nice to it.

Yes.


If you look at the pic below:



There is that much extra space WITHOUT the chain adjusters installed.

 

Okay...tonight...afterwork.

For the Record:

I am not saying that I was sold the wrong parts or un-machined parts. My original questions on my first post of this thread were:

-Maybe since the kit is used the metal of the spacers/Bracket has changed to make the fit less precise?

-Could my swing arm be bent or squeezed in slightly?

-Could there be something wrong with my Tensioners or my axle?

Am I missing something? (not an item but an idea)

 

Pat, I'm not trying to be an ass, I'm trying to help the guy. I don't know why it fit in your bike, and not in his; nor do I know if the carrier needs to be machined in order to complete a successful swap.

All I know is, that according to the pics I posted, my stock VF500F hub (which I have removed the studs from) matches the one that slowbird has. Maybe Jamie will chime in and point out some machining work that isn't visible in the pics.

Usually the hub is machined on those 5 bosses, allowing the sprocket to sit closer to the wheel, thus moving the chain line inboard, making up for the wider wheel having pushed it outboard. As you can see in the pics, both my stock hub and slowbird's hub place the sprocket in the same position on the hub. *This really has no bearing on the issue slowbird has however!*

In order to create space for these larger spacers, any machining would have occurred in the seat area of the hub bearing, thus moving the bearing inboard; OR, on the backside of the hub, on the face of the bosses that mate with the rubber dampers in conjunction with the outer diameter of the hub, which would allow the entire hub to sit farther inboard.

I do not see any evidence of either of these jobs having occurred, being that the bearing is clearly still in the stock location, and outer hub diameter appears to have original paint on it.

I assume by "shut some ppl up", you mean me, and again, I'm just trying to help here, not point fingers. Again, the pics I posted of my carrier are of a totally stock carrier, it has merely been sandblasted and painted.

 

...and I really appreciate any help/ideas/suggestions given. :smile:
