Title: Sprocket nut on rear wheel of '04 S4R won't budge
Post by: George S on October 13, 2014, 12:09:59 PM
So that's pretty much my issue. I'm in the process of replacing the eccentric hub. The nut on the right side (which is torqued even tighter) came off without too much difficulty. But this one on the left won't budge... and that's with a 40" cheater pipe on my breaker bar. I'm gonna soak the nut in WD-40 and try again later. Any other suggestions?

Also, I'll put this out there because I DO occasionally make stupid mistakes: yes, I am turning the nut CCW and yes i have removed the circlip.

Please help... if I don't get back on the road soon, I'm certain i'll go through withdrawal!

Soak with penetrating oil, then use an air or electric impact gun.

I've found the penetrating oil will stain white wheels, so apply only to the nut/thread area.

ime it varies from remove clip and spin off with fingers to drill holes thru two flats 180 degrees apart and split it with a cold chisel.

ATF and acetone in a 50/50 mix is the best

Thanks everyone! The thing finally budged, wheel has been removed, and hub replaced.

Here is my current hold up:

Brake pads. Where is the best place to buy and is there a particular brand anyone recommends?

Chain and front sprocket. I cannot find in my manual the limit for chain stretch, i.e. when it should be replaced. Also, the manual recommends replacing both sprockets and the chain all at the same time. If I have to replace the chain (probable. the bike has 20K miles) then I don't really mind shelling out for a front sprocket. What front sprocket do you recommend? Oh also, how do you replace a chain? This is not described in the manual either

Also, on the Rick's Motorsports website, there is an OEM Rectifier for $120 and there is a "Hot Shot" (allegedly cooler running) r-r for $150. Does anyone have experience with these? Is the Hot Shot worth the extra $30?

Thanks for your advice, everyone. I'll keep you updated.

George
