PR5020 Chain Guide: Choosing the Best Replacement Bars (5 Pro Tips)

1. Bar Length: Size Matters (But Not Always in the Way You Think)

The length of your chainsaw bar is one of the most critical factors to consider when choosing a replacement. It directly impacts the size of wood you can cut, the maneuverability of the saw, and even your safety. I’ve seen countless beginners overestimate their needs and end up with a bar that’s too long, making the saw unwieldy and dangerous.

Why Length Matters:

• Cutting Capacity: This is obvious, but worth stating. A longer bar allows you to cut through larger diameter logs. However, don’t assume that bigger is always better.
• Maneuverability: A shorter bar makes the chainsaw more agile and easier to control, especially in tight spaces or when pruning branches. Think about it like this: a longer lever requires more force to control.
• Safety: A longer bar increases the risk of kickback, a sudden and forceful reaction that can cause serious injury. I once witnessed a novice user struggling with a too-long bar on a small tree. The kickback nearly threw him off balance, and it was a close call.
• Power Requirements: A longer bar requires more power from the chainsaw engine to drive the chain effectively. If your PR5020 is struggling to keep up with a longer bar, you’ll experience reduced cutting speed and increased wear and tear on the engine.

Finding the Right Length for Your PR5020:

The PR5020 is typically compatible with bars ranging from 16 to 20 inches. However, the ideal length depends on the type of work you’ll be doing.

• 16-inch Bar: Excellent for pruning, limbing, and cutting small trees and firewood. It’s the most maneuverable option and ideal for beginners. I often use a 16-inch bar for clearing brush and small-diameter trees around my property.
• 18-inch Bar: A good all-around choice for general-purpose cutting. It offers a balance of cutting capacity and maneuverability. This is a solid choice for most homeowners who need to cut firewood and occasionally fell larger trees.
• 20-inch Bar: Best suited for felling larger trees and cutting thicker logs. Requires more experience and strength to handle safely. I reserve my 20-inch bar for tackling mature hardwoods that require the extra reach.

Data Point: According to a study by the National Institute for Occupational Safety and Health (NIOSH), chainsaw kickback is a leading cause of chainsaw-related injuries. Using a shorter bar can significantly reduce the risk of kickback.

Pro Tip: If you’re unsure which length to choose, start with a shorter bar. You can always upgrade to a longer bar later if needed. It’s better to have a saw that’s easy to control than one that’s overpowered and dangerous.

Personal Story: I remember when I first started using chainsaws, I was convinced that a longer bar was the only way to go. I bought a 24-inch bar for my small chainsaw, thinking I could tackle anything. The first time I tried to fell a tree, I nearly lost control of the saw due to kickback. That was a humbling experience and a valuable lesson learned.

2. Bar Type: Solid, Laminated, and Sprocket-Nose – Understanding the Differences

Chainsaw bars aren’t just solid pieces of metal. They come in different types, each with its own advantages and disadvantages. Understanding these differences is crucial for choosing the right bar for your PR5020.

The Three Main Types of Chainsaw Bars:

• Solid Bars: These are made from a single piece of steel and are the most durable and long-lasting type of bar. They are typically used by professionals who demand the highest level of performance and reliability. However, they are also the most expensive and heaviest option. I’ve seen loggers use solid bars for years, even decades, with proper maintenance.
• Laminated Bars: These are made from multiple layers of steel that are bonded together. They are lighter and less expensive than solid bars, making them a popular choice for homeowners and occasional users. Laminated bars are generally strong enough for most tasks, but they are not as durable as solid bars. I use a laminated bar on my lighter-duty chainsaw for trimming and limbing.
• Sprocket-Nose Bars: These bars have a sprocket (a small wheel with teeth) at the tip. The sprocket helps to reduce friction and improve cutting speed, especially when plunging the bar into wood. Sprocket-nose bars are often used by professionals for felling trees and cutting firewood. However, the sprocket can wear out over time and needs to be replaced.

Here’s a table summarizing the key differences:

Which Type is Best for Your PR5020?

For most PR5020 users, a laminated bar is the best choice. It offers a good balance of durability, weight, and cost. It’s strong enough for most cutting tasks and won’t break the bank.

If you’re a professional who uses your PR5020 frequently and demands the highest level of performance, a solid bar might be worth the investment. However, be prepared to pay a premium.

A sprocket-nose bar can be a good option if you do a lot of felling and firewood cutting. The sprocket helps to reduce friction and improve cutting speed. However, be aware that the sprocket will need to be replaced periodically.

Data Point: A study by Oregon Products found that sprocket-nose bars can increase cutting speed by up to 15% compared to solid bars when plunging the bar into wood. However, they also found that sprocket-nose bars require more frequent maintenance.

Pro Tip: When choosing a bar type, consider your budget, the type of work you’ll be doing, and your maintenance skills. If you’re not comfortable replacing a sprocket, stick with a laminated or solid bar.

Personal Story: I once tried to save money by buying a cheap, no-name laminated bar. It lasted only a few months before the layers started to separate. I learned my lesson: it’s better to invest in a quality bar from a reputable manufacturer.

3. Matching the Drive Link Count: The Unsung Hero of Chain Compatibility

This is where things can get a little technical, but it’s absolutely crucial to get right. The drive link count refers to the number of small, tooth-like links on the chain that fit into the groove of the bar. If the drive link count doesn’t match the bar’s specifications, the chain won’t fit properly, and your chainsaw won’t work. It’s like trying to put the wrong key in a lock – it just won’t turn.

Why Drive Link Count Matters:

• Chain Fit: The correct drive link count ensures that the chain fits snugly in the bar’s groove. Too few links, and the chain will be loose and prone to slipping. Too many links, and the chain will be too tight and difficult to install.
• Proper Tension: The drive link count directly affects the chain tension. A properly tensioned chain is essential for safe and efficient cutting. A loose chain can derail and cause injury, while a tight chain can overheat and damage the bar and engine.
• Cutting Performance: The correct drive link count ensures that the chain engages properly with the wood. If the chain is too loose or too tight, it will not cut efficiently, and you’ll waste time and energy.

How to Find the Correct Drive Link Count for Your PR5020:

• Check the Bar: The drive link count is usually stamped on the bar itself, near the mounting end. Look for a number followed by “DL” or “drive links.”
• Consult the Owner’s Manual: Your PR5020 owner’s manual should list the recommended drive link count for different bar lengths.
• Count the Links: If you’re replacing an old chain, you can count the drive links yourself. This is the most reliable method, but it can be time-consuming.
• Use an Online Chart: Many chainsaw parts retailers have online charts that list the correct drive link count for different chainsaw models and bar lengths.

Example: Let’s say you have an 18-inch bar for your PR5020. The bar might be stamped with “18” 72DL,” meaning it requires a chain with 72 drive links.

Data Point: According to a study by Stihl, using the wrong drive link count can reduce cutting efficiency by up to 20% and increase the risk of chain derailment by 50%.

Pro Tip: Always double-check the drive link count before purchasing a new chain. It’s better to be safe than sorry.

Personal Story: I once ordered a new chain online without checking the drive link count. When it arrived, it was too short for my bar. I had to go through the hassle of returning the chain and ordering the correct one. It was a frustrating experience that could have been avoided with a little extra attention to detail.

4. Some manufacturers are known for their quality, durability, and performance, while others are more focused on price. Choosing a reputable brand can make a big difference in the lifespan and performance of your bar.

Pro Tip: Don’t be afraid to spend a little extra money on a quality bar from a reputable brand. It will save you money in the long run by lasting longer and performing better.

Personal Story: I once bought a cheap, no-name chainsaw bar from an online retailer. It broke after only a few hours of use. I learned my lesson: it’s better to invest in a quality bar from a reputable manufacturer.

5. Maintenance for Longevity: Keeping Your Bar in Tip-Top Shape

Even the best chainsaw bar will eventually wear out if it’s not properly maintained. Regular maintenance can significantly extend the life of your bar and improve its performance.

Key Maintenance Tasks:

• Cleaning: After each use, clean the bar with a brush or compressed air to remove sawdust, pitch, and debris. This will help to prevent corrosion and wear. I always keep a small brush in my chainsaw kit for this purpose.
• Lubrication: Make sure the bar is properly lubricated. Use a high-quality bar and chain oil. Check the oil level frequently and refill as needed. A dry bar will quickly overheat and wear out.
• Filing the Rails: The rails of the bar (the edges of the groove) can become damaged or uneven over time. Use a bar rail dressing tool to file the rails and keep them smooth and even. This will improve chain tracking and reduce wear.
• Cleaning the Oil Holes: The oil holes in the bar can become clogged with debris. Use a small wire or needle to clean the oil holes and ensure proper lubrication.
• Checking for Damage: Regularly inspect the bar for cracks, bends, or other damage. Replace the bar if it is damaged.
• Rotating the Bar: Periodically rotate the bar to distribute wear evenly. This will help to extend the life of the bar. I try to rotate my bars every few weeks.

Why Maintenance Matters:

• Extended Lifespan: Regular maintenance can significantly extend the life of your chainsaw bar, saving you money in the long run.
• Improved Performance: A well-maintained bar will perform better, cutting more efficiently and reducing the risk of chain derailment.
• Increased Safety: A damaged or poorly maintained bar can be dangerous. Regular maintenance can help to prevent accidents.

Data Point: A study by the U.S. Forest Service found that properly maintained chainsaw bars last up to 50% longer than bars that are neglected.

Pro Tip: Make maintenance a regular part of your chainsaw routine. A few minutes of maintenance after each use can save you a lot of time and money in the long run.

Personal Story: I once neglected to clean the oil holes in my chainsaw bar. The bar quickly overheated and seized up. I had to replace the bar, which was a costly and frustrating experience. I learned my lesson: regular maintenance is essential for keeping your chainsaw in tip-top shape.

Expert Quote: “The key to a long-lasting chainsaw bar is proper lubrication and regular maintenance,” says Bob Johnson, a professional logger with 30 years of experience. “Don’t skimp on oil, and take the time to clean and inspect your bar after each use.”

Additional Considerations for PR5020 Bar Selection

Beyond the core tips outlined above, there are a few other nuanced factors that can influence your choice of replacement bar for your PR5020. These are the details that separate a good decision from a great one.

Understanding Kerf and Chain Pitch

• Kerf: The kerf is the width of the cut made by the chainsaw chain. A narrower kerf requires less power from the engine, which can improve fuel efficiency. However, a narrower kerf may also be more prone to binding in certain types of wood. The PR5020 is generally used with chains that provide a good balance between cutting speed and kerf width.
• Chain Pitch: The chain pitch is the distance between three consecutive rivets on the chain, divided by two. This measurement needs to match the bar’s specifications. Most PR5020 models use a 0.325″ pitch chain, but double-check your owner’s manual to confirm.

The Importance of Bar Material

While most chainsaw bars are made from steel, the type of steel can vary significantly. Higher-quality steel will be more resistant to wear, bending, and cracking. Look for bars made from alloy steel or hardened steel for increased durability.

Consider the Nose Type

Beyond sprocket-nose, there are other variations in the bar nose design:

• Hardnose Bars: These have a solid, hardened nose. They are very durable but can generate more friction than sprocket-nose bars.
• Replaceable Sprocket-Nose Bars: As the name suggests, the sprocket nose can be replaced when it wears out. This is a cost-effective option for those who use sprocket-nose bars frequently.

Environmental Factors

The type of wood you’re cutting and the environment in which you’re working can also influence your bar choice.

• Hardwood vs. Softwood: Hardwoods like oak and maple are more abrasive than softwoods like pine and fir. If you’re cutting a lot of hardwood, you’ll need a more durable bar.
• Dirty Conditions: Working in dirty or sandy conditions can accelerate wear on the bar and chain. Regular cleaning and lubrication are especially important in these environments.

Case Study: Optimizing Bar Length for Firewood Production

I once worked with a small firewood producer who was struggling to keep up with demand. He was using a 20-inch bar on his PR5020, thinking it would allow him to cut larger logs faster. However, he was constantly experiencing chain binding and slow cutting speeds.

After analyzing his operation, I recommended switching to an 18-inch bar. This shorter bar allowed him to maneuver the saw more easily and cut through smaller logs more quickly. The result was a significant increase in his firewood production rate. He also reported less fatigue and fewer instances of chain binding.

Key Takeaway: Don’t assume that a longer bar is always better. The optimal bar length depends on the size of the logs you’re cutting and the type of work you’re doing.

Addressing Common Concerns

• “My bar keeps bending. What am I doing wrong?” Bending can be caused by several factors, including using the wrong bar for the job, improper chain tension, and hitting foreign objects like rocks or nails. Make sure you’re using the correct bar for your PR5020, maintain proper chain tension, and avoid cutting into anything other than wood.
• “My chain keeps derailing. How can I prevent this?” Chain derailment is often caused by a loose chain, a worn bar, or a damaged chain. Check the chain tension regularly, inspect the bar for wear, and replace the chain if it’s damaged.
• “How often should I replace my chainsaw bar?” The lifespan of a chainsaw bar depends on several factors, including the type of bar, the type of wood you’re cutting, and the amount of maintenance you perform. As a general rule, you should replace your bar when it becomes excessively worn, damaged, or bent.

The Future of Chainsaw Bar Technology

The chainsaw industry is constantly evolving, and new technologies are being developed to improve the performance and durability of chainsaw bars. Some of the emerging trends include:

• Lightweight Bars: Manufacturers are developing lighter bars using advanced materials like carbon fiber and aluminum alloys. These bars reduce fatigue and improve maneuverability.
• Self-Lubricating Bars: Some bars are designed with internal oil reservoirs that automatically lubricate the chain. This eliminates the need for manual lubrication and ensures consistent performance.
• Smart Bars: Some bars are equipped with sensors that monitor chain tension, temperature, and other parameters. This information can be used to optimize cutting performance and prevent damage.
