Product Information
Full details
The Park Tool FR-3 Freewheel Remover is an essential precision tool designed for bicycle mechanics and cycling enthusiasts who need to remove SunTour four-notch freewheels manufactured since 1986. Its primary benefit is a specialized thin-wall construction that eliminates the need to dismantle axle cones or locknuts, significantly speeding up drivetrain maintenance. Please note that while it is highly effective for its intended purpose, it is exclusively compatible with specific SunTour components and requires careful handling with a skewer or axle nut to ensure it stays seated during operation.

FAQs
Does this tool work with Shimano freewheels?
No, the FR-3 is specifically designed for SunTour four-notch freewheels and will not fit Shimano splines.
Do I need to remove the wheel from the bike to use this?
Yes, you must remove the wheel from the bicycle frame to properly access the freewheel and use the FR-3 effectively.
What size wrench do I need for the base?
The base is 1-inch, so you can use a large adjustable wrench or a fixed 1-inch wrench.
Is the FR-3 made of hardened steel?
Yes, it is constructed from heat-treated alloy tool steel for maximum durability.
What is the center bore size?
The center bore is 10mm, which is designed to accommodate the axle diameter of most compatible wheels.
Can I use this with an impact wrench?
It is not recommended; manual force with a wrench or bench vise is standard practice to prevent damaging the freewheel or the tool.
Troubleshooting
The tool keeps slipping out of the notches during removal.
Ensure the tool is held firmly in place by using a quick-release skewer or axle nut tightened against the tool base.
The tool will not slide onto the freewheel.
Check the freewheel for debris or damaged splines, and verify that the freewheel is actually a 4-notch SunTour model.
Pros and Cons
Pros
- Saves significant time by eliminating the need to disassemble the axle assembly
- Heat-treated steel provides excellent durability under high torque
- Works with both shop bench vises and standard hand wrenches
- Compact and lightweight for easy inclusion in a tool roll or workbench
Cons
- Not compatible with Shimano or other non-SunTour freewheel standards
- Requires proper user technique to ensure the tool does not slip during high-force removal
- Cannot be used on freewheels that do not match the specific 4-notch pattern
Setup, Compatibility & Care
To ensure the longevity of your FR-3, keep the tool clean and free of heavy corrosion. While the heat-treated steel is robust, store it in a dry environment. When setting up for removal, always ensure your axle is properly cleared of any obstructions that exceed the 10mm center bore diameter. If you are using a bench vise, ensure the tool base is fully seated before applying force to prevent damage to the notches. Periodically inspect the 4 notches for any signs of deformation; if the notches become rounded, the tool should be replaced to prevent potential damage to your freewheel.
