Mafia Bike Cassette Teardown: Visual Guide to Removing Stuck Drivers

Uncover the essential facts surrounding Mafia Bike Cassette Teardown: Visual Guide to Removing Stuck Drivers in this special report.

Freeing a frozen driver begins by stripping external hardware away from the dropouts. Secure the wheel flat on a clean workbench with the drive side facing upward.

1. Remove the Outer Hardware: Use a deep-well 17mm socket to spin off the outer axle nuts and washers. Inspect the exposed threads for galling or flattening, which commonly happens when chains derail and wedge into the dropout slot.
2. Hold the Axle Flats: On the non-drive side, look for the narrow wrench flats machined into the locknut or cone spacer. Slip a 17mm cone spanner wrench onto these flats to hold the axle stationary. Fit an open-end wrench onto the drive-side locknut or axle extension.
3. Back Off the Lockrings: Rotate counter-clockwise to break the non-drive locknut free. If the non-drive assembly uses a threadless push-on dust cap, gently lever it upward using plastic pry tools to avoid scarring the aluminum.
4. Free the Axle Shaft: Thread one axle nut back on by three full turns on the non-drive side to protect the axle threads. Tap that nut firmly with a brass drift or rubber mallet. This drives the axle through the hub toward the drive side, carrying the driver bearing assembly out with it.
5. Perform Freehub Body Removal: As the axle moves outward, grasp the 9T driver or multi-cog carrier by hand and wiggle it outward with a counter-clockwise twist. Turning it counter-clockwise depresses the pawls against their springs, letting them glide past the internal ratchet teeth without binding.

Never strike the bare end of an axle with a steel hammer. Unprotected hammer strikes flare the threaded steel, making it impossible to slide bearings or cone spacers off the shaft without extensive thread-file restoration.
