Seized Freewheel!

[Bike Hoarder]

The more i think about it, the more i remember the sad faces of people when nothing can be done. We had a titanium Cannondale road bike with a seized seatpost, couldn't move it at all.... if only for a few pence of grease. I've got an old Cinder Cone frame with a seized post, came to me like it. My Father-in-law is using some industrial strength caustic soda which is slowly corroding the post, without destroying the frame, hopefully!!!

I suppose guys, the moral of the story is.... Copper grease threads, seatposts, even Q/R's before it's too late!!! :cry:

yep - thats the rules. Unfortunately most of us buy 2nd-hand stuff and these wheels with freewheel fitted fallin that category, and I doubt the freewheel was fitted by the seller (to me) either!

Had to remove a seized freewheel just last week.
Undid bearings cover, usually unscrews clockwise using a hole punch and a hammer to tap via the 2 indentations on the covers surface.
Pulled out all the barings and pulled off the sprocket body.
Heated the inner threaded portion stuck to the wheel, boiling waters all I had.
Jammed a bolt between the sprocket bodies ratchet teeth and one of the recesses that would hold the ratchet spring.
Fit a chainwhip to the sprockets (the inner ones are often on splines and cant come unscrewed, you dont want the sprockets to unscrew) and put handle inside a length of pipe to increase effective length and thus leverage of the handle.
Bit more boiling water on freewheel then give almighty heave !!!!!!!
HEY PRESTO freewheel came off.
Better to use a vice though !

Always use copper grease when installing freewheels if you wish to reuse a freewheel.

Cheers

Kev you probably heard, I had the same problem with my Suntour cassette. Nothing anyone could do.

Build two chain whips out of 5' steep pipe? Pull until something gives or breaks.

true Mike - but it's not a cassette. Its a freewheel - screws onto the hub like this:

its ok Kev - 'guaranteed indestructable'....

im sure i removed one once by removing the sprockets with two whips and removing all the guts so it was just the inner part of the freewheel left on the hub,clamped this by its sides in a vice and cracked it off,obviously completely destroys the freewheel!!
