Before you roll up your sleeves and get down to the nitty-gritty of removing the wheel retaining clip, assembling the right set of tools is crucial. Fumbling for the correct tool mid-process is frustrating and can pose safety risks.

Essential Tools

  • Pliers: A pair of needle-nose pliers best grip the small retaining clip securely.
  • Flathead Screwdriver: Useful for prying the clip open if it’s a bit tight or rusted.
  • Wrench: An adjustable wrench may be needed for loosening any nuts that secure the wheel to the axle.
  • Jack or Wooden Blocks: For elevating the lawn mower to access the wheel assembly easily.

Safety Gear

Just as vital as the correct tools are appropriate safety precautions. Never underestimate the value of safety, especially when working with mechanical components.

  • Gloves: Protects your hands from cuts and abrasions.
  • Eye Protection: Safety glasses are a must to shield your eyes from flying debris or accidental splashes of lubricant.
  • Closed-Toe Shoes: Always wear sturdy shoes to protect your feet from heavy components that might fall.

Preparation Steps

Before removing the wheel retaining clip, it’s essential to establish a safe and effective working environment. Here’s how to get started:

Safety First

Your safety should be your top priority. Always start by shutting off the lawn mower completely. For an added layer of safety, disconnect the spark plug.

This simple step ensures that the mower cannot accidentally start while you’re working on it, significantly reducing the risk of injury.

Elevating the Mower

With the mower powered off and the spark plug disconnected, your next step is to elevate the machine to access the wheel assembly comfortably. You can tip it on its side if you’re working on a push mower.

However, use a mechanical jack or sturdy wooden blocks for larger riding mowers to lift it. Ensure the mower is stable before proceeding to prevent any unexpected movements.

Wheel Removal

At this stage, you’re ready to remove the wheel from the axle shaft, setting the stage for the retaining clip’s removal.

Use an adjustable wrench to loosen and remove the nut if your mower’s wheel is bolted onto the axle. Once the nut is off, gently pull the wheel away from the axle shaft.

Identifying the Retaining Clip

Locating the retaining clip is a critical step; doing it right could save you much time and frustration. While it’s tempting to think that all retaining clips look the same, they can differ significantly depending on the brand and model of your lawn mower.

Generally, you’re looking for a small, often metallic piece that fits into a groove on the wheel’s axle shaft. It may be C-shaped, E-shaped, or even appear as a small pin inserted through a hole in the axle.


The material and color can offer clues to its condition. A shiny, silver-colored clip is likely in good shape, whereas a rusty or discolored one might need replacing soon. Some clips might even have small tabs or ‘ears,’ which are there to help you remove them using pliers.

If your retaining clip has a loop or hole at one end, that’s usually designed for easier removal or added security.


Typically, you’ll find the retaining clip on the outside end of the axle, near where the wheel fits onto it. It’s designed to sit securely in a groove or notch to prevent the wheel from sliding off the axle during operation. The clip could be integrated into the wheel hub itself in some cases, especially with more advanced or specialized mowers.

Visual Aid

(Here, images or diagrams would be invaluable for the reader to quickly identify what they’re looking for. It could be an annotated image pointing out the location and features of a typical retaining clip on a lawn mower wheel assembly.)

Removing the Retaining Clip

Successfully identifying the retaining clip is only half the battle; the real task lies in removing it without causing damage to the surrounding components. Here’s how to approach it in a detailed manner:

Removing the Retaining Clip

Accessing the Clip

First and foremost, ensure that you’ve followed all the safety precautions and preparatory steps we’ve discussed. You can access the retaining clip once the lawn mower is properly elevated and the wheel is removed.

If any other elements like washers or spacers are in the way, remove them cautiously, noting their arrangement for reassembly.

Using Pliers

Here, a pair of needle-nose pliers becomes your best ally. The pliers’ slender, elongated tip allows for precise control. Carefully grip one end of the retaining clip with your pliers.

For clips with ‘ears’ or tabs, aim to grip these for optimal leverage. Once gripped, apply a steady, measured force to pull it out (in the case of pin-style clips) or spread it open enough to slide it off the axle (for C-shaped or E-shaped clips).

A pro tip: If the retaining clip feels too tight or shows resistance, consider applying a few drops of penetrating oil to loosen any rust or grime. Let it sit for a few minutes before attempting removal again. This will make the task easier and mitigate the risk of damaging the clip or axle.

Alternative Methods

While pliers are generally the most effective tool for this job, you may find yourself in situations where alternatives are needed. A flathead screwdriver can also serve the purpose in some cases, especially for E-shaped or C-shaped clips.

Insert the screwdriver’s flat end into the gap between the clip and the axle and gently pry it open, taking care not to apply too much force, which could bend or break the clip.

Understanding the peculiarities of your specific retaining clip—whether it’s the material it’s made of, the amount of force needed for removal, or the best angle to approach it—can greatly ease the removal process.

With the right technique and care, you can safely remove the clip, making way for any maintenance or replacements needed.

Removing the Retaining Clip

Now that we’ve identified the retaining clip and prepared the mower for this task, it’s time to delve into the removal process. 

Inspecting for Damage

Once the clip is removed, take a moment to inspect both the clip and the axle for any signs of wear, bending, or corrosion.

This can help you decide whether it’s prudent to replace the clip or if the old one can be reused. It’s a quick yet often overlooked step that can save you future headaches.

Marking the Position

Before removing the clip, marking its original position on the axle with a piece of masking tape or a marker might be beneficial. This ensures you’ll place it back in the correct position during reassembly, especially if multiple grooves or notches are present.

Using a Magnet

Tiny parts like retaining clips can easily be lost in the grass or cluttered workbench. Using a magnet to hold the clip once it’s removed ensures you won’t lose it and can be especially useful if you plan to reuse the clip.

Double-Check Alignment

After removal, check to ensure that no other parts were accidentally shifted or dislodged in the process. Confirm that washers, spacers, or any other components are still in their correct places or note their positions for reassembly.

Documenting the Process

If your lawn mower model is a bit more complex or you’re new to this kind of task, taking photos at each stage of the removal process can serve as a useful guide for both reassembly and for any future occasions where you’ll need to remove the clip again.

Pro Tips for Smooth Removal

After 30 years of working with lawn mowers and their components, I’ve gathered some tricks of the trade that can make the removal of a retaining clip not just easier but also more efficient.
