Step-by-Step Guide to Fix Lock Out Suspension Fork

You’re zipping along the trail, and out of nowhere, your mountain bike’s front suspension decides it doesn’t want to play nice—yep, that lockout is sticking worse than an old piece of gum under a park bench.

It happens to the best of us; it looks like we’ve both been initiated into the club that occasionally wrangles with a finicky lockout mechanism—it can be quite the head-scratcher. But hey, don’t sweat it! Today, I’m here to break down some easy-to-follow steps that’ll have you dominating your ride’s suspension once again.

Hang tight—the solution for turning that obstinate fork back into a trusty companion is just around the bend.

Key Takeaways:

• If your lockout suspension fork isn’t working, check for leaky oil, adjust air pressure, and look at the lockout lever.
• Keep your bike’s suspension smooth by changing the damper oil and often cleaning parts like stanchions and seals.
• Use tools and a clean space to work on your bike. Replace any broken parts you find inside the fork or lever.

Reason	Description
Leaking Damper Oil	Dirt and Grime build up
Inadequate Air Pressure	Insufficient air pressure causing improper suspension function
Oil Contamination	Oil mixing with air or other parts in the fork lowers
Broken or Loose Lockout Lever	Mechanical failure or loosening of the lockout lever
Dirt and Grime Build-up	Accumulation of dirt and grime inside the fork, leading to malfunction
Worn-out Internals	Wear and tear of internal components such as O-rings and seals over time

Understanding the Problem- Lockout Suspension Fork Not Working:

Ever hit the trails and felt your front fork giving way, even with the lockout engaged? It’s a buzzkill. Turns out, this common hiccup has its culprits—dirt build-up, air pressure mishaps, or oil viscosity may be betraying your bike’s usually steadfast suspension.

Let’s roll up our sleeves; fixing this can mean the difference between a shaky descent and that locked-in control we all crave on our mountain biking adventures.

Common Reasons for Lockout Failure:

Lockout problems can stop you from getting the most out of your mountain biking adventure. Let’s tackle some common reasons why your front fork’s lockout might not be working properly.

• A big issue is leaking damper oil. If the oil starts coming out, the lockout won’t work right.
• Not enough air pressure in the suspension fork is another problem. It needs the right amount to hold up your weight and lock correctly.
• Sometimes, oil gets where it shouldn’t be. If it mixes with air or other parts in the fork lowers, that’s bad news.
• The lockout lever could be broken or loose. This can happen with Suntour forks and others, too.
• Dirt and grime build up over time. They can get inside and mess things up, making the lockout stick or not engage at all.
• The internals might be worn out. Things like O – rings and seals don’t last forever, especially if you ride a lot.

STEP 1– Checking and Adjusting the Air Pressure:

I love riding my bike, but sometimes, the suspension fork can give me trouble. A common fix is to check and adjust the air pressure. Here’s how you get it done right:

• Grab your shock pump and connect it to the valve on your fork.
• Look at the current pressure reading; now you know your starting point.
• You’ll want to set the sag correctly; that’s how much your fork compresses with you on the bike.
• Add air in small steps, about 5 psi at a time, to avoid adding too much.
• Test the sag after each adjustment by sitting on the bike in your normal riding position.
• Bounce lightly on the suspension to see if it reacts smoothly.
• Keep adjusting until you find that sweet spot where it’s not too soft or too hard.
• Make sure you don’t exceed the maximum air pressure marked on the fork.

STEP 2– Examining and Replacing the Damper Oil:

Fixing a lockout suspension fork often needs a close look at the damper oil. Leaking or low damper oil can make your fork fail to lock.

• First, check for oil leaks around the suspension fork. Oil on your fork could mean there’s a problem inside.
• Get ready to work on your bike. Make sure you have all the tools and a clean space.
• Carefully take apart the suspension fork following its manual. Keep track of all parts.
• Look for signs of old or dirty oil in the damper. This could be why it’s not locking.
• Drain out all the old damper oil from the fork. Be slow and steady to avoid spills.
• Remove the damper from the fork if needed. Check it for damage or wear.
• Replace any worn-out parts in the damper before putting new oil in.
• Fill with fresh, high-quality damper oil to the right level for your fork model. Don’t overfill!
• Reassemble your suspension fork carefully using clean parts and tools.
• Test out your bike’s lockout feature after reassembly. It should work smoothly now.

STEP 3– Removing and Inspecting the Lockout Lever:

I want to share with you all how to remove and inspect the lockout lever on your bike’s suspension fork. This is a key part of making sure your rides are smooth.

• First, check that the lockout lever moves easily on the handlebar.
• If it’s stuck, try using a little oil around it to help loosen things up.
• Gently pry up the lock lever from a 2020 Suntour NEX fork to remove it.
• Carefully pop the lever off any other type of Suntour suspension fork.
• Look closely at the removed lockout lever for signs of damage or wear.
• Refer to your fork’s service manual for detailed steps to take the lever apart and check its parts.
• Replace any broken or worn parts you find inside the lever mechanism.
• Put back any small springs or clips exactly where they were before.
• After putting everything back together, make sure the lockout function works properly.

Additional Tips for Maintaining Your Suspension Fork:

So, you’ve got your lockout suspension fixed. Great! Now, let’s keep it smooth. RockShox says to service your fork every 50 hours of riding. This means changing the oil so everything runs nice and easy.

Make sure to clean the stanchions and seals with a microfiber towel after rides too. Dirt can hurt your fork, but cleaning stops that.

Clean bits mean a happy bike. Wipe off all the yucky stuff and swap out bath oil when needed – this keeps your air spring healthy. Keep up with both the fork and shock maintenance; they last longer that way.

Learn how mountain bike suspension works—it’s key for keeping it all in top shape!

Final Thought:

Fixing a lockout suspension fork can often be a do-it-yourself job. You may need to check the air pressure, replace the damper oil, or look at the lockout lever. Sometimes, parts wear out, and you have to buy new ones.

Remember to use your lockout when climbing hills for better performance. With these tips, keeping your bike’s suspension in top shape is simpler than you might think!
