Hey all, Bought a used 65T rear sprocket and rear brake disc for my old 2009 rear two bearing wheel. I want it as a swap out unit for local riding and I want my 3 bearing rear wheel for long hauls loaded. Anyway I gave $ 100 for the disc, sprocket and the wheel which I was told was an 09' but its casting #'s indicates more likely an 07' or 06'. The wheel had one of the bearing surfaces smacked up pretty bad when whoever used a chisel to remove a outer race? The Question is this, upon looking the parts over more closely I discovered a good nick in one tooth and also the hard coating on the belt surface is chipped up. What is that shit? I thought it was paint from when the guy tried painting his wheels or some shit. I stripped off the powdercoating and bead blasted the few remaining paint specs after stripping and tried, TRIED to blast off the rest of the crap which is on the belt surface of the sprocket. Its some hard shit and its seems to be .004 to .006 thick. Any Idea what this is? Teflon? Ceramic, something to keep down wear? Anyway, I had ordered the new hardware to install the disc and sprocket from American Sportbike and decided to just buy a damn new sprocket and screw messing with this terd I bought. The disc is in great shape but does not have the 4 larger holes drilled in its hole pattern like my 09' does. Older style I guess? Make much difference in stopping feel or what? If I can get the stuff off the Sprocket I will get it hard anodized but now with the new one in the mail I will probably shit can it. BDRAG | ||

The difference with the rotor does not apply to the XB. The holes are there for 1125 models which require you to remove the caliper when installing/removing the wheel. All 08+ XBs have that hole as its easier than having 2 different rotors available. (Message edited by froggy on April 13, 2011) | ||

Cool! So what about the coating on the Sprocket? I feel if its all jagged it will cause wear on the belt even though its small imperfections. BDRAG | ||

I think it's a thick coating of hard anodizing. Ever wonder why belts wear out and not sprockets? You may have led your sprocket to premature failure by removing that coating. Not to worry you. It will take thousands of miles to wear out the raw aluminum. I feel if its all jagged it will cause wear on the belt even though its small imperfections. Yes. The belt actually leaves some material behind, which I think helps in keeping friction down. I have a new belt, and a used one right now. I will measure the teeth in the morning, and let you know the difference in size. | ||

Gunut75 Thanks, I didn't know what it was thats coated on. I am puzzled some what still. When we have parts at the machine shop I work at plated, anodized, the most that can be built up is a total, both surfaces of a part, say a shaft, is only .0015. One and onehalf thousands thickness total or .00075 a side. It seems thicker than that. Also never seen anodize flake off. Seems more like some tuff ass paint or ceramic. It don't matter anyway now, I ordered the new sprocket anyways! HAhahaaaaaaa. Let me know on the belt wear though. Thanks..... BDRAG | ||

Okay. The used belt measures .333 wide on 1 tooth. The new one measures .348. There is a loss of material there. I can't be sure though. I am only measuring 2 belts. Wish I had a dozen or so. Polish that old pulley and anodize it! Make a "bling" piece out of it.  |
