[RBW] Re: Freewheel Skipping
The very next ride the pawls skipped a half dozen times. It has been removed and I'm slowly dripping oil/WD-40 through it. (Don't have a solvent bath...yet). It also appears that Shimano has started making freewheels again. Picked up a couple from the LBS, market as $19.99 and they gave me a couple bucks off that. A rather unique looking freewheel design...somewhat cassette like. Shifts fine.

[RBW] Re: Freewheel Skipping
Thanks to all for the thoughtful replies. I believe it was the pawls inside the freewheel that skipped. There is no gunk build up or visible wear on the cogs, no measureable wear on the chain. I'll give the soaking the FW in solvent technique a go. Thanks!

I want to use it on a set of wheels I am building for my forthcoming 650b road bike. I recently decided not to go with a NOS fluted Campy SR crankset on the bike after reading too many accounts of the cranks breaking (I think you were on a recent discussion of same on the IBOB). Any one know whether the super light Campy freewheel is prone to pawls giving way? I suppose Campy may have used somesort of super aluminium alloy to come in so far under its competitor's weight.

[RBW] Re: Freewheel Skipping
I'll agree with Mark that you can probably stop the "skipping" and extend the life of of the freewheel with some solvent, followed by some lubrication. I've done this with both freewheels and freehubs with varying degrees of success. Seriously though...If this freewheel has indeed provided "reliable service for decades" it is probably time to replace it. Pawls, bushings, bearings and races do wear out. Cogs do too, although the wear may not be readily apparent...

[RBW] Re: Freewheel Skipping
Angus, If the FW body itself skips from not engaging.. from my experience it's from grease inside becoming gunked up inside causing the pawls to miss engaging. I've had this happen with multiple Sachs FW's because of the grease they use from the factory. Suntour FW's always came oiled, but depending on age and maintenance, these can get gummed up too. As Mark Stated .. you can soak it a solvent, or flush it well with WD-40 which is a good solvent on it's own. Let it dry overnite or with compressed air and lube with PW oil or any Standard SAE 30 weight motor oil(much thicker than auto motor oil). -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

I was riding my Atlantis yesterday and during one hard effort (it's all relative) the freewheel skippedchunk! It's an old Suntour 7 speed freewheel that has probably given reliable service for decades. I had this happen to another Suntour freewheel several years ago and when it became too regular I replaced it. Which lead to the question... With a skipping freewheel, how long do you let it go before replacing the freewheel? Well, being a cheap b*d I try riding in different gear combinations to avoid the worn cog as long as I can, but really your freewheel should be replaced now if you can't find replacement cogs. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Freewheel Skipping
My solution was to immerse the freewheel in some kind of cleaning solvent, agitate to float any dirt or impurities away, dry the freewheel out and wipe it down, then lube the pawls with Phil Wood oil. Lubing is done by dripping the oil into the gap between the outermost cog and the freewheel body. Here's how to lube the freewheel while it's on the bike, as preventive maintenance: http://sheldonbrown.com/freewheels.html#lube On Feb 1, 3:51 am, Angus wrote: > To set the stage, I'm happily stuck in a 7 speed / freewheel world, > understand how freewheels work, do all my own bicycle maintenance > etc... > > I was riding my Atlantis yesterday and during one hard effort (it's > all relative) the freewheel skippedchunk!
