The vehicle suspension system’s shaft and bore housing use a ring that fastens them together.
As a motorist, cyclist, or DIYer, it’s essential to know how to carry out simple maintenance procedures. One of these maintenance procedures includes learning how to remove snap rings.
Sometimes, both entry-level and expert mechanics find it challenging to remove snap rings, especially without tools.
This article will explain what a snap ring is, what they are used for, and how to remove them. Some snap rings come without holes, making them difficult to remove with snap ring pliers.
We have that in mind. We’ll also explain procedures on how to remove snap rings without pliers.
Understanding Snap Rings
Snap rings, also known as circlips, are a type of fastener utilized in various mechanical applications to hold components in place.
They can be found in engines, gear systems, and other machinery where retaining parts is essential. Understanding their design and function is crucial for effective removal without specialized tools such as pliers.
Snap rings typically come in two types: external and internal. External snap rings fit into a groove on the outside of a shaft, while internal snap rings fit into a groove on the inside of a bore.
When attempting to remove these rings without pliers, it is vital to consider the type of snap ring you are dealing with.
How to remove a snap ring?
Removing a snap ring can be a challenging or easy task based on the approach and tools you use. Remember, a workman is as good as his tools. This section will discuss how to remove snap rings with pliers. Follow the steps below religiously;
Step 1: Gain access to the snap ring.
The foremost step is to gain access to the snap ring. If you intend to remove a wheel hub snap ring, dismantle the hub assembly and expose the snap ring.
Step 2: Insert the tip of a snap ring tool.
Insert the tip of a snap ring removal tool into the snap ring holes. Most snap rings have holes on the two ends.
Step 3: Widen the snap rings.
Pull the arms of the snap rings by opening the removal tool [preferably snap ring pliers]. Once you open the removal tool, the snap ring will widen. Insert a flathead screwdriver on the wide part of the ring.
Keep widening the ring by shifting the screwdriver to close the parts. You may need a second screwdriver to keep opening the holes.
Step 4: Pull off the snap rings.
If you don’t have a screwdriver with you, or the snap ring is not too tense, continue with only the snap ring pliers.
The moment you have extended the snap rings and the shoulders are out of the groove, gently pull it off the housing.
Gently close the pliers so the snap ring won’t shoot out and injure someone. Close gently until the ring falls off.
Step 5: Clean the groove.
Clean the groove and prepare it for replacement. Ensure there is no rust and dirt on the track for easy installation.
Removing External Snap Rings Without Pliers
External snap rings are generally a bit easier to deal with when improvising. The goal is to spread the ring open.
Method 1: Using Two Screwdrivers.
This is perhaps the most common and effective way to remove an external snap ring without specialized pliers.
What you’ll need:
- Two small, flat-head screwdrivers.
- Possibly a hammer (for gentle persuasion).
- Gloves for better grip.
Steps:
- Assess the Snap Ring: Look at the snap ring. You should see the two holes at the ends.
- Position the Screwdrivers: Insert the tip of one screwdriver into one of the holes on the snap ring. Insert the tip of the second screwdriver into the other hole.
- Apply Gentle Pressure: Slowly and steadily, begin to twist both screwdrivers away from each other. This action will spread the snap ring apart.
- Watch for Expansion: As you twist, the snap ring should start to expand and lift out of its groove on the shaft.
- Remove the Ring: Once the ring has expanded enough, you can carefully lift it off the shaft. Be prepared for it to spring off, so keep your fingers clear.
Tips for Success:
- Start Small: Use the smallest screwdrivers that will fit snugly into the holes. This gives you more control.
- Even Pressure: Try to apply pressure evenly with both screwdrivers. Uneven pressure can cause the ring to bind or even break.
- Patience is Key: Don’t force it. If it’s not moving, try wiggling the screwdrivers slightly or applying a bit of penetrating oil.
- Gentle Tapping: If the ring is really stuck, a very light tap on the handle of each screwdriver with a small hammer can sometimes help break it free. Be extremely careful not to hit the surrounding components.
Method 2: Using Needle-Nose Pliers (with Caution).
While not ideal, in some situations, needle-nose pliers can be used to grip the ends of an external snap ring.
What you’ll need:
- A pair of needle-nose pliers.
- Gloves.
Steps:
- Grip the Ends: Carefully grip the outward-facing edges of the snap ring with the tips of the needle-nose pliers. Aim to get a firm hold on the metal.
- Pull Apart: Gently pull the handles of the pliers apart. This action should spread the snap ring.
- Lift and Remove: As the ring expands, try to lift it out of its groove.
Caution:
- Slippage: The smooth jaws of needle-nose pliers can easily slip off the snap ring, especially if there’s any grease or oil present.
- Damage Risk: Applying too much force or gripping the wrong part of the ring can bend or damage it, making it unusable for reinstallation. Use this method only if you have a good grip and the ring isn’t too stiff.
Method 3: Using a Nail or Thick Wire.
This method is a bit more primitive but can work in a pinch, essentially creating a makeshift snap ring remover.
What you’ll need:
- A sturdy nail or a piece of thick, rigid wire (like from a coat hanger, but sturdier).
- Pliers (to bend the wire/nail if necessary).
- Hammer (optional).
Steps:
- Prepare the “Tool”: If using a nail, ensure its tip is somewhat pointed. If using wire, bend a small hook or a blunt end that can engage the hole.
- Position the Tool: Insert the nail or bent wire into one of the snap ring’s holes.
- Apply Leverage: Use a second nail or wire in the other hole, or use a screwdriver for leverage against the first tool. Gently push or twist to spread the ring.
- Remove: Once expanded, carefully lift the snap ring off.
Considerations:
- Strength: Ensure your chosen item is strong enough not to bend or break under pressure.
- Grip: It can be harder to get a good grip with these items compared to screwdrivers.
Removing Internal Snap Rings Without Pliers
Removing an internal snap ring without the proper tool is slightly trickier because you need to compress the ring inwards. The principle is to apply opposing force to the holes to bring them closer together.
Method 1: Using Two Screwdrivers (for Internal Rings).
This is a common approach for internal snap rings, similar to the external method but with the opposite action.
What you’ll need:
- Two small, flat-head screwdrivers.
- Gloves.
Steps:
- Locate the Holes: Peer into the bore where the internal snap ring is seated. Find the two holes.
- Insert Screwdrivers: Carefully insert the tip of one screwdriver into one hole. Insert the tip of the second screwdriver into the other hole.
- Apply Inward Pressure: Gently push the screwdrivers towards each other. This will cause the snap ring to contract.
- Compress and Lift: As you compress the ring, it should lift out of its groove. You might need to angle the screwdrivers slightly inwards.
- Remove Carefully: Once compressed enough, carefully pull the snap ring out of the bore.
Key Techniques:
- Angle of Entry: You might need to angle the screwdrivers slightly to get them to engage the holes properly and exert inward pressure.
- Control is Crucial: For internal snap rings, it’s vital to maintain control. If the ring suddenly springs free, it can be hard to find or could damage the surrounding area.
- Visibility: Good lighting is essential when working with internal snap rings to ensure you’re engaging the holes correctly.
Method 2: Using Pliers and a Pick/Screwdriver.
This combination can be effective for prying internal snap rings.
What you’ll need:
- One pair of needle-nose pliers.
- One small, flat-head screwdriver or a pick.
- Gloves.
Steps:
- Engage One Hole: Use the screwdriver or pick to push one end of the snap ring inward, compressing it.
- Grip the Other End: While holding the ring compressed with the screwdriver/pick, use the needle-nose pliers to grip the other end of the snap ring.
- Compress and Manipulate: Use the pliers to further compress the ring while simultaneously pulling it out of the groove.
- Remove: Once free from the groove, carefully remove the snap ring.
Tips for this Method:
- Practice: This method requires a bit more dexterity. Practice the motion on a loose ring if possible.
- Steady Hand: Keep your hand steady to avoid slipping.
Method 3: Using Two Picks or Awls.
If the holes are small or recessed, you might find that two pointed tools like awls or dental picks work better than screwdrivers.
What you’ll need:
- Two small, pointed picks or awls.
- Gloves.
Steps:
- Insert Picks: Insert the tip of one pick into one hole and the tip of the second pick into the other.
- Apply Inward Force: Gently push the picks towards each other. This action will compress the internal snap ring.
- Lift and Remove: Once compressed, lift the snap ring out of its groove.
Advantages of Picks:
- Precision: Picks allow for precise engagement with smaller holes.
- Better Grip: The pointed tip can sometimes provide a better grip than the flat tip of a screwdriver.
Common Mistakes to Avoid
- Using the Wrong Tools: Trying to use excessive force with thin or weak tools can lead to them breaking, potentially causing injury or damage.
- Forcing It: Snap rings are designed to flex, not to be forced or bent beyond their intended limits. Overstressing them can cause them to break.
- Not Wearing Eye Protection: This is a critical safety step that cannot be overstated.
- Working in a Cluttered Space: A clean, organized workspace reduces the risk of tools slipping or parts getting lost.
- Damaging Grooves or Shafts: Be mindful of where you are applying pressure to avoid scratching or deforming the grooves or the shaft itself. This can make future removals or installations difficult.
FAQs.
Q: Can I reuse an old snap ring after removing it without pliers?
It depends on the condition of the snap ring. Inspect it carefully for any bending, stretching, or signs of wear. If it looks perfect, you might be able to reuse it. However, for critical applications or if there’s any doubt, it’s always best to use a new snap ring.
Q: What kind of screwdrivers are best for removing snap rings?
Small, flat-head screwdrivers that fit snugly into the holes of the snap ring are ideal. You might need two of them. Precision screwdrivers or those from a watch repair kit can be very useful for smaller snap rings.
Q: How do I prevent the snap ring from flying across the room when I remove it?
Work in a confined space if possible, or place a rag or magnetic tray around the area where the snap ring is located. Apply slow, controlled pressure, and be ready to catch the ring as it comes free.
Q: My snap ring is really stuck. What else can I try?
If lubrication and gentle persuasion with screwdrivers aren’t working, you might have a severely corroded or deformed snap ring.
In such cases, it might be safer to try and cut it off with a small cutting tool like a Dremel with a cut-off wheel or a small hacksaw blade, being extremely careful not to damage the surrounding components. However, this should be a last resort.
