Does anybody have problems shearing off the splines on your front drive sprocket? Do you have to keep tightening the nut? It has happened three times in 20,000 miles. The last time I bought a jims locking flange nut and that was supposed to cure the nut getting loose along with the sprocket. 6300 miles later i'm sitting on the curb at a gas station in Delaware wonder what is going on. My S2 mabey has mabey 65 HP if I'm lucky and I don't thrash "Buella" on a daily basis. So I'm asking you all for your insight. Thanks, Chris | ||

Do you drag race or drop the clutch to launch a wheelie every now and then? Still, there must be something systemic that is causing your failures. That is really strange. Only things I can imagine are out of tolerance/worn shaft splines (too small) and/or poor quality sprockets. The first failure may have buggered the shaft splines enough to then lead to subsequent sprocket failures? | ||

I've burned up 2 on my X1 with only 6,000 miles yet my S3 has 14,000 and never did it. One key I believe is to locktight the nut so that it doesn't spin off. | ||

Blake: I thought the same thing, but I checked the plines after each time with a magnifing glass. Something I do do from time to time are 2ng gear wheelies. They are just to much fun. I noticed to that the sprocket wears on the back side where the spacer butts up against it. The second time it happened I down shifted over some railroad tracks and the back tire hopped twice before it caught and took out the sprocket but this time was doing 40 mph in a straight line looking for a dinner so I wasn't abusing it by any means. I know there has got to be lots of riders that are harder on these than I am. | ||

been awhile since i was down this road on my S2, but as i recall there were problems with the original-design sprocket and nut, and there's a "newly" designed kit avail from H-D/Buell, for about $85-ish, includes EVERYTHING you need. again, i'm going on memory here, but having had this problem (you're damn right i do 2nd-gear wheelies), the kit fixed it. see your dealer, they'll (maybe...) know what to do. ride to lean, FB  | ||

FB: I'll check it out. Thanks SG | ||

ok, Shot Gun, here ya go! p/n 40202-91B, includes pulley, plate, nut, bolts, and seals, cost $78.50 (+ tax) on 11/5/97. be SURE, if you go this route, to replace the old seals behind the pulley (there are two as i recall, one called a "quad seal" as i recall) with the new ones in the kit. these seals are what keeps the muck and the mire from migrating down the output shaft into the trans case when your Thunderingbolt is parked so farrrrrrrrr over on it's spiffy (i'm being nice) sidestand. if this kit fixes your problem, you owe me a (very dark) beer. what the heck, if it doesn't work, you STILL owe me a beer!

LOL chuckle chuckle. You got it,thanks a ton. I just replaced all the seals last month but just for good measure I'll do it again. Mabey you need some of that Dockside Beer out of Mass. That stuff is dark and chewy  Thanks again, Chris | ||

women and beer...dark and chewy...yum and yummer! FB | ||

The earlier model years would still have the skinnier pulleys (in the spline area). Its about 1/2" wide. A later upgrade, from 98 up, I think, is about 3/4"(?) wide, which requires changing the spacer (and seal). | ||

OH. I'll have to check it with my old ones. thanks, SG | ||

SG: The trans pulley nut will never agin loosen if you use a Jims nut. It is rather expensive at $50. The thing is built with an attached flange (rather than it being a separate piece) positioned a few thosandths above the surface of the pulley. After torquing (which you may take to 100 ft. lbs.) and hole matching the keeper allen bolts will distort the flange serving as lockwasher. | ||

Is there a easy test for this problem? | ||

I know mine was caught just before it went(1995 S-2) when I had it in for some other minor thing at about 30k,also I remember the first time I met Gordon Buhle was on the side of the road coming back from a ThunderPress gig.His pulley on his S-2 had given up on him.Seems like a trend--- | ||

Jmartz: That is what I had on there already and the Harley dealer told me the same thing. Yet I sat in Delaware with a sheared sprocket. I'm going to check that kit to see if the pulley has been beefed up at all. The threads on the nut were stripped but the nut was still fastened to the pulley? If I get some time I'll post pic's.

SG: A bad batch of those pulleys was circulating around. It is possible you have encountered more than one. In 1995 HD widened the contact area from .500 to .750 making the part somewhat stronger. The stock nut.keeper works well also. I jjst like trick stuff. | ||

I like what works  Thanks for the info. I'll check it out. SG | ||

just an up date: The pulley I striped was .75" and was part of a kit. It wasn't sold to me that way though. I had to drill and tap holes in the pulley to make the jims nut work plus with no spacer it has me wondering?  The new kit is $95.45. That seems to be the going rate for the kit(I checked three harley dealers). It is alittle salty but if it fixes my problem I'll be very happy. SG |
