(New!) Topic : Rear hub - thanks, GerPa!  Author  Post     MotorMac  Jupiter Reg. Date  :  29/08/2010 Posts  :  1,850 Location  :  Nor Cal, United States Posted : 10 Aug 2021 - 20:29   Post title : Rear hub - thanks, GerPa!   Revisiting the rear hub and bearings - and CIRCLIP - using our Forum, and ran across this great old thread: Link Looks like a pair of 6204s in hub and a 6205 at belt pulley. Finding quality bearings is a bit different now, Timken isn't what it used to be, and Japanese bearings might be best. Still not convinced the symphony I hear on acceleration in a turn is bearing-related, but running out of other guesses.    Author  Post     Leethal  Zeus Reg.

For a while I had this sound on acceleration at lower speeds, thought it was something to do with the belt or pulley dampener, but I'm now sure it was my hagon springs moving around or chattering. I have been playing with the rear shocks for a while (had to send them back to hagon UK for rebuild $$$) but now that I have a lot more spring preload wound on, no noise, so try this, nothing to lose.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.

Never thought of shocks - they're stock, so, y'know, what could go wrong? It has a sheet metal quality, that sound. Not a bearing sound necessarily, not the belt... What you say makes perfect sense. And believe me, that's extremely rare these days. Highly prized. Thank you, should be an easy test, too. You da man.    Author  Post     Leethal  Zeus Reg.

(Re: Leethal)   I'll add my thanks to GerPa too. That belt changing tutorial was what got me to order one and get it done.

(Re: Leethal)   Lee, I turned my shocks down from 5 to 4, nothing rubbing, everything seems solid. Was immediately greeted by same noise (sample #4 in "name that sound" post). No change. Thinking it might be Cush drive, I shot some graphite into hub, but still no change.....    Author  Post     Leethal  Zeus Reg.

(Re: MotorMac)   I had a similar sound but mainly just when taking off or rolling it backwards. Completely went away when i put a new tire on which leads me to suggest just taking your wheel off then reinstalling and maybe cleaning away any dirt and grease and applying some grease. I think a lot of sounds from the rear are just flukes that will right themselves when removing and reinstalling the wheel same was as re seating an electrical plug will often right electrical issues.   2010 Blue/White Thunderbird, "Brutus". 1700 kit, short tors, gutted cat, UNI filter, filter seal off, custom tune.

Not a bearing sound necessarily, not the belt... What you say makes perfect sense. And believe me, that's extremely rare these days. Highly prized. Thank you, should be an easy test, too. You da man. If the outer bearing is on its way out it will make a squeely metalic type of sound. A squirt of spray oil will dull the sound if that is what it is. I always recommend fitting the best quality bearings possible. Jap bearings are fine. Wheel bearings will have red seals ..... although I have fitted ones with black seals (industrial) and they were fine.   My first natural instinct is to breathe. My second is to evade tax's.
