Front Sprocket issues

[BajaRon]

Which loctite to use? Blue or Red???

I am not sure what is recommended. But I would not use Red (even if recommended). If you use the Red then that is the last time you will ever get that bolt off. You might as well weld it on! :yikes:

I have to disagree about the splines on the shaft. They don't look good to me IMHO. The shaft needs to be replaced too, but not right away. If it was mine I would put a new sprocket on. Continue to drive it and make arrangements to get it fixed properly.

Having just gone through this 2 weeks ago on a friends 2008 GS SE5, I have to disagree..the splines on the shaft look fine, it's a hardened shaft, the sprocket is pot metal and much softer material. If the spline (main) shaft needs to be replaced it's all over for a 2008 GS with 28k miles on it. Minimum dealer parts and labor exceeds $3500.00. Major job. Some dealers wanna sell you a short block.

Get the new sprocket, new bolt, red loctite and torque it to 85flb and ride it for another 28k miles (check the bolt at each oli change).

Where did the flats go on the top of the splines?

Not all output shafts have wide splines with the spline peak flat and matching the shaft OD. My KTM uses a fine spline on the output shaft. It does have small narrow flats at the top, nothing like a Japanese bike. Those shafts do get destroyed since the steel countershaft sprocket is secured by a snapring and the movement wears the shaft.

I am not sure if wear exists from the photos, but they don't look bad either. Personally, I would slide the tip of a scribe or similar along the splines length and inspect for a worn step. From there decide what action to take.

FWIW, prior to installing the bolt with threadlocker, ensure cleanliness of the threads both on the bolt and inside the shaft. Something that cleans and dries with no residue is best. Some say Brakleen does leave a residue but I have used it for ears with no issues when using threadlockers.

All the best with it.

Billy..not sure about the flats on that shaft, may have never had them or the photo might not show them well. The softer pulley could not have caused that much damage to the hardened shaft. Take a look at my link http://www.spyderlovers.com/forums/...ve-Front-Drive-Sprocket-HELP!!&highlight=elkk I think he will be fine.

New sprocket and Bolt overnight from Canada. Installed with blue loctite torqued at 85ftlbs. Test drive no more noises. Re checked torque and it was still good. Marked sprocket and bolt with paint. Rode 400 miles to SpyderFest with no issues. Bolt didn't move. Thanks Everyone!!!!!!! Now time to enjoy SpyderFest 2015!!!!!!!
