Hub Service - Please help before I make a stupid mistake(5 posts)

Hub Service - Please help before I make a stupid mistakeRob11966
Aug 11, 2003 4:14 AM
I have recently upgraded my Shimano 105 wheelset. Plan to keep them as a spare pair. I am currently servicing them for storage and have noted that the freehub is stiff and gritty. The pawl mechanism still works but it is clearly in need of a clean and lube. Trouble is that I cannot seem to take the freehub apart. I have it off the wheel of course. I am thinking of washing it in mineral turps a few times and then soaking it for a couple of days in 'home brew' lubricant. Is this the way to go about it? Can the hub be taken apart? Is there some way to inject grease?
BTW the wheels gave me a couple of good years riding - Only required minor truing once.
Thanks in advance.

i wouldn't soak it in anything (especially solvent) and definitely don't try to take it apart. simply pry off the thin rubber seal on the pawl side and drip some lube (pedros syn or phil's or something similar) down into the narrow seam that's exposed. let it sit for a couple hours and the new lube should flow through to the other side and flush out the grit.

there's also a tool called the "freehub buddy" and can buy that fits into the freehub and lets you pump lube into it more efficiently. it's about $20 at www.loosescrews.com
You can disassemble, BUT ...Atombomber

if you're not confident, don't do it. There are 50 (yes, fifty) 1/8" loose ball bearings that tend to scatter once they are set free. Coupled with springs and pawls going their own way, I'd say try to get it working by oiling it, and order a new freehub body for when this one blows. Once you have the new one, then tackle the repair job. If you can't do it, at least you won't be stuck to ride. There is a post on this site about how to do the rebuild, just search.

Thanks for the info.
The park tool site was especially useful. Ended up degreasing the freehub by flushing through with degreaser. Then washed the degreaser out with shellite (loads of crap came out) and blowing it dry with compressed air. Finally flushed it through with oil. Repeated the oil flush several times. Now works like new. Once again thanks for the advice.
Cheers
