Howdy All:

I hope you are well.

It is a long story but I ended up with a new to me front wheel along with rotors, abs ring, bolts and washers. They all did not necessarily come from the same bike or even same year.

I went to put the pieces together today and both rotors do not tighten, they have a bit of a rattle. I am guessing that the washer things are to deep.

Any thoughts on what I may or may not need to get this corrected? I wanted to get a new tire mounted on this so I could keep riding my bike, basically just swap wheels? Maybe I just need diferent washers?

Any and all help greatly appreciated.

The bike I have is a 2000.

They're supposed to be slightly loose laterally, with essentially no play in the circumferential direction -- they are floating discs.

They ae floating rotors, they uses a wavewasher and a set torque. Check the manual.

Check the part fiche

Wonderful. That looks like what I am missing. The Wavewasher

34 11 2 314 888 wave washer

I have the roll pins, that is what I was calling washers above.

Ok, another question if you do not mind--

What is the diference between the rotors?

01 34 11 2 314 894 brake disc right
01 34 11 2 314 893 brake disk left

They seem exactly the same to me.

Anyone know?

Sorry to be a bother.

one is for the left side one is for the right.

Just a *guess*: Check the mounting flanges on each -- the left rotor may have notches or be thinner to accommodate the ABS ring mounting flanges.

If I do not see any difference do I need to worry about it or just run with it?

There is likely a reason for the difference. I no longer have a non-EVO brake LT, but SWMBO's R1150GS has the same pre-EVO brakes as the '00 LT -- I'll take a look at them when I get home tonight to see if I can spot a difference.

Thanks Mark I really appreciate it.

Tony,

If the rotors have a different part number, then there is a difference. You may not notice it with the naked eye, but it is there. I know the Integral and non-integral brakes use a different ABS ring, and my guess is that the rim lugs for mounting the brake disks are different heights hence the rims have different part numbers. Also note that the Integral brakes run different calipers, different brake pads, and different diameter rotors as well.

You could just slap it all together and hope it works, but I don't think I'd take that chance with my wheels. Study the parts fiche diagram, check all the part numbers against model year, put it all together with the all the correct parts and in the correct order, then try it and see if everything lines up correctly.

The brake rotors and calipers have some play to account for pad wear, but I wouldn't want to put in a wheel combo that is out of alignment from the start due to incorrect assembly or the wrong parts. Just not worth it.

Your original post suggests that you aren't that familiar with how this is all supposed to go together, or even confident that you have all the right parts. But in the end it's your choice how to proceed.
