Husqvarna 455 Chainsaw Chain Replacement (5 Expert Tips)

Husqvarna 455 Chainsaw Chain Replacement: 5 Expert Tips for Loggers in the Pacific Northwest (and Beyond!)

Living and working in the Pacific Northwest, surrounded by towering Douglas firs and majestic cedars, I’ve learned a thing or two about chainsaws. They’re not just tools here; they’re an extension of our hands, a vital part of our livelihoods, and sometimes, our only way to stay warm through those long, wet winters. But even the best chainsaws need regular maintenance, and one of the most crucial aspects of that is knowing how to properly replace the chain.

I’ve seen firsthand the frustration of a dull chain slowing down a logging operation, the danger of a poorly installed chain causing kickback, and the sheer waste of time and energy that comes from not knowing the right techniques. That’s why I’ve put together these five expert tips, honed from years of experience felling trees, bucking firewood, and teaching others the ropes. These tips aren’t just for professionals; they’re for anyone who relies on a Husqvarna 455 and wants to keep it running smoothly and safely. Whether you’re cutting firewood in your backyard in Oregon, clearing land in British Columbia, or just maintaining your property, these insights will help you get the job done right.

1. Understanding Your Chain: Identifying the Right Replacement

Before you even think about touching a wrench, you need to understand your chainsaw chain. It’s not a one-size-fits-all world. Using the wrong chain on your Husqvarna 455 can lead to poor cutting performance, increased wear and tear on your saw, and even dangerous situations.

What to Look For:

Pitch: The pitch is the distance between any three consecutive rivets divided by two. It’s crucial for matching the chain to the sprocket and bar. The Husqvarna 455 Rancher typically uses a .325″ pitch chain, but always double-check your saw’s manual or the markings on the bar to confirm. Using the wrong pitch will prevent the chain from meshing correctly with the sprocket.
Gauge: The gauge is the thickness of the drive links (the part that fits into the groove of the bar). The most common gauge for the 455 is .058″, but again, verify with your bar or manual. A chain with the wrong gauge won’t fit properly in the bar groove, leading to binding or the chain jumping off.
Drive Link Count: The drive link count is the number of drive links on the chain. This needs to match the length of your bar. To determine the number of drive links, count them on your old chain before removing it. A chain with too few drive links will be too short to fit on the bar; one with too many will be too long and won’t tension properly.

Why It Matters:

I remember a time when a new helper on my crew, eager to get started, grabbed a chain that looked “close enough.” He ended up stripping the sprocket and damaging the bar within an hour. The cost of the repair far outweighed the initial savings of not taking the time to identify the correct chain.

Data Point: A study by Oregon State University’s College of Forestry found that using the correct chain pitch and gauge can increase cutting efficiency by up to 15% and reduce bar and chain wear by as much as 20%. This translates to significant savings in time and money over the lifespan of your chainsaw.

Pro Tip: Always keep a spare chain on hand. When you buy a new chain, note the pitch, gauge, and drive link count in your chainsaw’s manual. Better yet, write it directly on the chainsaw itself using a permanent marker. This will save you time and headaches later. Also, consider purchasing a chain filing kit and learning how to sharpen your own chains. A sharp chain is a safe chain, and it will significantly improve your cutting performance.

2. Safety First: Preparing for the Replacement

Chainsaws are inherently dangerous tools, and even a simple task like replacing the chain requires careful preparation. I’ve seen too many accidents happen due to carelessness or lack of attention to safety.

Essential Safety Gear:

Gloves: Heavy-duty work gloves are essential for protecting your hands from sharp chain teeth and potential cuts.
Eye Protection: Safety glasses or a face shield will shield your eyes from flying debris and sawdust.
Hearing Protection: Prolonged exposure to chainsaw noise can cause permanent hearing damage. Wear earplugs or earmuffs.
Long Sleeves and Pants: These will provide a barrier against scratches and cuts.
Steel-Toed Boots: Protect your feet from falling logs and accidental contact with the chain.

Preparing Your Work Area:

Clear the Area: Ensure you have a clear and stable workspace free from obstructions.
Secure the Chainsaw: Place the chainsaw on a flat surface and engage the chain brake. This prevents the chain from moving during the replacement process.
Disconnect the Spark Plug: This is a crucial step to prevent accidental starting of the chainsaw while you’re working on it. Remove the spark plug wire and tuck it away from the spark plug.

Why It Matters:

I once witnessed a near-miss when a coworker, rushing to replace a chain, didn’t disconnect the spark plug. He accidentally bumped the throttle, and the saw briefly started. Thankfully, the chain brake was engaged, but it was a stark reminder of the importance of following safety procedures.

Data Point: According to the Consumer Product Safety Commission, chainsaws cause over 36,000 injuries annually in the United States alone. A significant portion of these injuries are preventable through proper safety precautions and training.

Pro Tip: Before starting any chainsaw maintenance, take a few minutes to review the safety instructions in your chainsaw’s manual. It’s also a good idea to take a chainsaw safety course offered by a local community college or forestry organization. Knowledge is your best defense against accidents.

3. The Replacement Process: Step-by-Step Guide

Now that you’ve got the right chain and you’re geared up safely, let’s get down to the nitty-gritty of replacing the chain.

Step-by-Step Instructions:

Loosen the Bar Nuts: Use the wrench that came with your Husqvarna 455 (or a comparable socket wrench) to loosen the bar nuts that secure the bar cover. Don’t remove them completely yet.
Loosen the Chain Tension: Locate the chain tensioning screw (usually on the side of the saw near the bar). Turn it counterclockwise to loosen the chain tension. You should be able to easily move the chain around the bar.
Remove the Bar Cover: Once the chain is loose, remove the bar nuts completely and take off the bar cover.
Remove the Old Chain: Carefully remove the old chain from the bar groove and the sprocket. Pay attention to how the chain is oriented; this will help you install the new chain correctly.
Inspect the Bar and Sprocket: Before installing the new chain, inspect the bar for any damage, such as burrs, wear, or unevenness. Use a bar dressing tool to remove any burrs and smooth out the edges. Also, check the sprocket for wear or damage. A worn sprocket can damage a new chain and reduce cutting efficiency. If the sprocket is worn, replace it.
Install the New Chain: Place the new chain around the sprocket, ensuring that the cutting teeth are facing in the correct direction (they should point forward on the top of the bar). Guide the drive links into the bar groove, working your way around the bar.
Position the Bar: Place the bar back onto the saw, aligning the bar studs with the holes in the bar. Make sure the chain is properly seated in the bar groove.
Reinstall the Bar Cover: Put the bar cover back on and tighten the bar nuts finger-tight.
Adjust the Chain Tension: Use the chain tensioning screw to adjust the chain tension. The chain should be snug against the bar but still able to be pulled around by hand. A good rule of thumb is to pull the chain away from the bar in the middle. You should be able to see about half the drive link.
Tighten the Bar Nuts: Once the chain tension is properly adjusted, tighten the bar nuts securely with the wrench.
Check the Chain Tension: After tightening the bar nuts, double-check the chain tension. It should still be snug but not too tight.

Why It Matters:

Proper chain tension is critical for both performance and safety. A chain that’s too loose can jump off the bar, while a chain that’s too tight can overheat and break. I’ve seen both happen, and neither is a pretty sight.

Data Point: A study by the U.S. Forest Service found that proper chain tension can reduce the risk of chain breakage by up to 30% and increase chain lifespan by up to 25%.

Pro Tip: After installing a new chain, run the chainsaw at idle speed for a few minutes to allow the chain to seat properly. Then, re-check the chain tension and adjust as needed. It’s also a good idea to lubricate the chain with bar and chain oil before starting to cut.

4. Troubleshooting Common Issues: When Things Go Wrong

Even with the best preparation and technique, things can sometimes go wrong during the chain replacement process. Here are a few common issues and how to troubleshoot them:

Chain Won’t Stay on the Bar: This is usually caused by incorrect chain tension, a worn bar, or a damaged sprocket. Check the chain tension first and adjust as needed. If the problem persists, inspect the bar and sprocket for wear or damage and replace them if necessary.
Chain is Too Tight or Too Loose: This is usually due to improper chain tension adjustment. Loosen the bar nuts and adjust the chain tensioning screw until the chain is snug but not too tight. Retighten the bar nuts and double-check the tension.
Chain is Binding or Not Cutting Smoothly: This can be caused by a dull chain, a damaged bar, or improper chain lubrication. Sharpen the chain or replace it if necessary. Inspect the bar for damage and repair or replace it. Make sure the chain is properly lubricated with bar and chain oil.
Chain is Smoking or Overheating: This is usually caused by insufficient chain lubrication or excessive chain tension. Check the oil reservoir and make sure the chain is getting adequate lubrication. Loosen the chain tension if it’s too tight.

Why It Matters:

Knowing how to troubleshoot common issues can save you time, money, and frustration. I’ve learned that a little bit of troubleshooting knowledge can go a long way in the woods.

Data Point: A survey of chainsaw users found that the most common issues encountered during chain replacement are related to chain tension and lubrication. Addressing these issues promptly can significantly extend the lifespan of your chain and bar.

Pro Tip: Keep a small toolkit with you when you’re working with your chainsaw. This toolkit should include a wrench, a screwdriver, a chain filing kit, and a bar dressing tool. Having these tools on hand will allow you to quickly address any issues that arise in the field.

5. Chain Maintenance: Extending the Life of Your Investment

Replacing a chainsaw chain can be a bit of a hassle, so it’s in your best interest to extend the life of your chain as much as possible. Proper chain maintenance is key to achieving this.

Essential Maintenance Practices:

Chain Sharpening: Regularly sharpen your chain to maintain its cutting efficiency. A dull chain is not only less efficient but also more dangerous. Learn how to use a chain filing kit or take your chain to a professional sharpening service. I personally prefer to sharpen my own chains.
Chain Lubrication: Always use bar and chain oil to lubricate the chain. This reduces friction and wear and tear. Check the oil reservoir regularly and refill as needed. I prefer using a high-quality, biodegradable bar and chain oil to minimize environmental impact.
Bar Maintenance: Regularly clean and inspect the bar for damage. Use a bar dressing tool to remove any burrs and smooth out the edges. Flip the bar periodically to distribute wear evenly.
Chain Cleaning: Clean your chain regularly to remove sawdust and debris. Use a brush or compressed air to clean the chain after each use.
Proper Storage: When not in use, store your chainsaw in a dry and safe place. Remove the chain and clean it thoroughly before storing it.

Why It Matters:

Proper chain maintenance not only extends the life of your chain but also improves cutting performance and reduces the risk of accidents. I’ve found that taking a few extra minutes to maintain my chain after each use pays off in the long run.

Data Point: Studies have shown that regular chain sharpening can increase cutting efficiency by up to 20% and extend chain lifespan by up to 50%. Proper lubrication can reduce chain wear by as much as 30%.

Pro Tip: Develop a regular maintenance schedule for your chainsaw. This schedule should include chain sharpening, lubrication, bar maintenance, and chain cleaning. Stick to this schedule, and your chainsaw will reward you with years of reliable service.

Regional Considerations in the Pacific Northwest:

In the Pacific Northwest, we often deal with very resinous woods like Douglas fir and hemlock. This resin can quickly gum up a chainsaw chain, making it dull and inefficient. To combat this, I recommend using a bar and chain oil specifically formulated for resinous woods. These oils contain additives that help prevent resin buildup and keep the chain running smoothly. I also find that cleaning the chain more frequently is necessary when working with these types of wood.
