To remove a wheel pin, gently grip the end of the pin with pliers and maneuver it out of the assembly.
Here's a more detailed breakdown:
-
Identify the Type of Pin: Wheel pins can vary. Common types include:
- Cotter Pins: These are bent wires inserted through a hole in the axle.
- Linx Pins (R-Clips): R-shaped clips that secure the wheel to the axle.
- Spring Pins (Roll Pins): Slotted, hardened steel pins that rely on spring tension.
- Groove Pins: Solid pins with grooves that compress when inserted.
-
Gather Your Tools: The most common tool needed is a pair of pliers (needle-nose or regular). You might also need:
- Punch or nail: For driving stubborn pins.
- Hammer: To tap the punch/nail.
- WD-40 or penetrating oil: To loosen corroded pins.
-
Remove Washers (If Present): Before removing the pin, check for any washers around the axle and remove them. Note their order for reassembly.
-
Removing Specific Pin Types:
-
Cotter Pins:
- Straighten the bent ends of the cotter pin with pliers.
- Grip the head of the pin with pliers and pull it straight out. If it's stuck, try tapping the opposite end with a punch and hammer.
-
Linx Pins (R-Clips):
- Simply pull the R-clip straight out. You may need to wiggle it a little.
-
Spring Pins (Roll Pins):
- Place a punch or nail on the end of the pin.
- Tap the punch with a hammer to drive the pin out. Make sure you are driving it out in the correct direction (typically from the side with the smaller diameter).
-
Groove Pins:
- Use a punch and hammer to drive the pin out. These pins are often a tight fit.
-
-
Dealing with Stubborn Pins:
- Penetrating Oil: Apply penetrating oil like WD-40 to the pin and let it sit for a few minutes to help loosen corrosion.
- Gentle Tapping: Use a hammer and punch to gently tap the pin, trying to break any corrosion.
- Patience: Don't force the pin too hard, as you could damage the surrounding components.
-
Reassembly: When reassembling, ensure the new pin is properly installed and any washers are placed back in their original order.
