Headset bearings.

Just lately my Claude Butler MTB front suspension has started making weird
creaking and clonking noises.

I scrounged it on Freecycle - the previous owner may have run into something
and bent the forks a little.

From time to time I find salvage, recently a Raleigh with fixed forks - the
difficulty of course is estimating whether the bearing cups will fit my
frame without taking both apart and losing various bits!

The relevant page on the Sheldon Brown site seems to be just a general guide
as to what sizes exist - it would be impossible to catalogue every make and
model.

Is there a "rule of thumb" to gague whether the bearing cups are *likely* to
fit before pulling it all apart?

Thanks for any help.

Yes: they won't.

Yes: they won't.

Thanks - but how do you know that?

At a cursory glance they look sort of similar-ish diameter.

What I haven't really looked at properly is the headset tube length, if the
target frame has a shorter head tube I need to take the donor apart to see
if the thread is cut far enough down the steerer tube.

AFAIK - both are British made - hopefully that counts for something?

Insufficient data.

Mr Scheidt writes as a man who has met Murphy once or twice.
The more critical it is, the less likely the available parts
will fit any given machine. That's true for more than
bicycles by the way.

If it's an O/S AH system and the cups are visible, that's a
relatively uniform spec.
There exist several 1" systems, notably with 26.4mm and
27.1mm crown race seats among other differences.
If the cups are internal all bets are off - too many of
those formats are circulating now. You'll need to remove the
headset and measure with the proper gauge to know both
diameter and angle of the bearing seats.

The R's a 1".....the Ritchey is OK no probs ...ifn you get rust under control.

Sheldon-Harris site is fairly clear...read it again.

try Jenson.

Scrap the old CB forks for an aheadset. Does a Walmart fit ?

if the tube is rusty n then cleaned out seat cups into thinned linseed oil over thinned n dried red Rusto. Let linseed dry maybe under infrared with a fan going if urine Michigan then squeeze in cups with a 1/2" threaded rod.

Thanks for the very useful link.

Mine is a Falcon Cycles variant, so I've a bit more digging to do.

But at least I've got a start.

I just want to say that the rumour that Murphy (of Murphy's Law) is Irish is grossly exaggerated. Murphy's family lived in Chigaco within sight of the stockyards for four generations. He was American through and through. I met his granddaughter once, and she was a prissy old bird with a mouth full of apple pie; she claimed that her granddaddy "only did God's work to punish sinful people".

But to the point, Murphy's observation is neither a
guideline nor a suggestion. It's a law.

I'll begin tracking AJ with Daniels' Law !

Sheldon-harris should solve the headset question but a vernier would help after disassembly....not doing that encourages Murphy more than only owning a CB variant.

owning a Flying Squirrel meshes with Murphy and Tempts Fate...

you can develop a list over a coupla pints no prob.. ummanuga akes 4 tries just gettingthis sentence in.....
