Are you tired of your 18-inch Craftsman chainsaw bar underperforming, leaving you frustrated with slow cuts and a lack of power?

I’m here to help you unlock its full potential with my top three expert tips for a Craftsman 18-inch chainsaw bar upgrade.

I’ve spent countless hours in the woods, felling trees, bucking logs, and preparing firewood, and I’ve learned a thing or two about maximizing chainsaw performance.

Let’s dive in and get your saw running like a pro!

The State of Wood Processing & Why Your Chainsaw Matters

Globally, the wood processing industry is a multi-billion dollar enterprise, with both industrial and personal use playing significant roles.

Whether it’s for construction, furniture, or the simple pleasure of a crackling fire, wood remains a vital resource.

In 2023, the global firewood market alone was estimated at over $10 billion, and is projected to grow steadily.

But here’s the rub: efficient and safe wood processing is key to sustainability and cost-effectiveness.

Your chainsaw, especially for us DIY enthusiasts and small-scale operators, is the heart of the operation.

A well-maintained and properly upgraded chainsaw can dramatically increase your productivity, reduce physical strain, and improve the quality of your work.

A Craftsman 18-inch chainsaw is a popular choice for many homeowners and hobbyists due to its affordability and versatility.

However, the stock bar often leaves something to be desired.

That’s where these upgrades come in.

Key Concepts Before We Begin

Before we get into the nitty-gritty, let’s define some key terms:

Green Wood vs.

Seasoned Wood: Green wood is freshly cut wood with high moisture content (often over 50%).

Seasoned wood has been dried (usually air-dried) to a moisture content of 20% or less, making it ideal for burning.
Chain Pitch: The distance between three consecutive rivets on the chain divided by two.

It determines the size of the chain and its compatibility with the bar and sprocket.
Chain Gauge: The thickness of the drive links that fit into the groove of the bar.
Kerf: The width of the cut made by the chain.

A narrower kerf requires less power.
Kickback: A dangerous phenomenon where the chainsaw suddenly kicks back towards the operator, often caused by the tip of the bar contacting an object.

Tip #1: The Bar Itself – Choosing the Right Replacement

The first and most impactful upgrade you can make is replacing the stock bar with a higher-quality one.

The stock bar on many Craftsman chainsaws is often a basic, entry-level model.

Upgrading to a professional-grade bar can significantly improve cutting performance, durability, and safety.

Why Upgrade the Bar?

Improved Durability: High-quality bars are made from tougher steel alloys that resist bending, wear, and damage.
Better Oil Delivery: Superior bars often have improved oiling systems that ensure adequate lubrication to the chain, reducing friction and extending the life of both the bar and chain.
Reduced Vibration: Some bars are designed with vibration-dampening features that make the saw more comfortable to use for extended periods.
Enhanced Cutting Performance: A well-designed bar can improve the chain’s ability to cut smoothly and efficiently.

Selecting the Perfect Replacement Bar

When choosing a replacement bar, consider these factors:

Length: Stick with the 18-inch length unless you have a specific reason to go longer or shorter.

Changing the bar length can affect the balance of the saw and its suitability for different tasks.
Mounting Pattern: This is crucial!

The bar must have the correct mounting pattern to fit your Craftsman chainsaw.

Refer to your chainsaw’s manual or the manufacturer’s website to determine the correct mounting pattern.

Common Craftsman patterns include A041, A074, and A095.

Cross-referencing this information is vital.
Chain Pitch and Gauge: The replacement bar must be compatible with the chain pitch and gauge of your chainsaw.

Most Craftsman 18-inch chainsaws use a 0.325″ pitch and a 0.050″ gauge chain.

Again, double-check your manual!
Type of Bar: There are several types of chainsaw bars:
- Laminated Bars: These are the most common type, consisting of multiple layers of steel welded together.
  
  They are relatively inexpensive and suitable for general use.
- Solid Bars: These are made from a single piece of steel and are more durable and resistant to bending than laminated bars.
  
  They are often preferred by professionals.
- Sprocket Nose Bars: These bars have a sprocket at the tip that reduces friction and wear on the chain.
  
  They are particularly useful for cutting hardwoods.

Recommended Bar Brands

Based on my experience and feedback from other wood processing enthusiasts, here are some reputable brands to consider:

Oregon: Oregon is a leading manufacturer of chainsaw bars and chains, known for their quality and durability.

Their Power Match and Pro-Lite bars are excellent choices.
Stihl: Stihl bars are renowned for their precision and performance.

While they are typically designed for Stihl chainsaws, some models are compatible with Craftsman saws.
Husqvarna: Similar to Stihl, Husqvarna bars are high-quality and durable, but compatibility can be an issue.
Carlton: Carlton offers a range of bars at a more affordable price point, making them a good option for budget-conscious users.

My Personal Recommendation: Oregon Power Match Bar

If I were upgrading a Craftsman 18-inch chainsaw bar, I would recommend the Oregon Power Match bar.

Here’s why:

Durability: The Power Match bar is made from a tough alloy steel that can withstand heavy use.

I’ve personally used this bar for felling large trees and bucking hardwoods without any issues.
Oiling System: The bar has an excellent oiling system that keeps the chain well-lubricated, reducing friction and extending the life of the chain and bar.
Replaceable Sprocket Nose: The Power Match bar has a replaceable sprocket nose, which is a significant advantage.

If the nose wears out, you can simply replace it instead of replacing the entire bar.
Compatibility: Oregon provides excellent compatibility charts on their website, making it easy to find the correct Power Match bar for your Craftsman chainsaw model.

Case Study: From Frustration to Firewood Champion

I once worked with a homeowner, let’s call him John, who was struggling to prepare firewood with his Craftsman chainsaw.

He was constantly battling slow cuts, chain slippage, and excessive vibration.

After diagnosing the problem, we determined that the stock bar was the culprit.

We replaced it with an Oregon Power Match bar, and the difference was night and day.

John was able to cut through logs much faster and with less effort.

He went from frustrated to firewood champion in a single afternoon!

Step-by-Step Bar Replacement

Here’s how to replace your chainsaw bar:

Safety First: Always wear gloves and safety glasses.

Ensure the chainsaw is turned off and the spark plug wire is disconnected.
Loosen the Bar Nuts: Use the wrench provided with your chainsaw to loosen the bar nuts on the side cover.

Do not remove them completely yet.
Adjust the Chain Tension: Turn the chain tensioning screw counterclockwise to loosen the chain.
Remove the Side Cover: Remove the bar nuts completely and take off the side cover.
Remove the Old Bar and Chain: Carefully remove the old bar and chain from the chainsaw.
Install the New Bar and Chain: Place the new bar onto the mounting studs, ensuring that the chain tensioning pin aligns with the hole in the bar.

Install the chain onto the bar, making sure the cutting edges of the chain are facing in the correct direction (they should point forward at the top of the bar).
Reinstall the Side Cover: Place the side cover back onto the chainsaw 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 the bar by hand.
Tighten the Bar Nuts: Tighten the bar nuts securely with the wrench.
Check Chain Tension: Double-check the chain tension after tightening the bar nuts.

Troubleshooting Bar Replacement

Bar Doesn’t Fit: Ensure you have the correct mounting pattern for your chainsaw.

Double-check the manufacturer’s specifications.
Chain is Too Loose or Too Tight: Adjust the chain tensioning screw until the chain is snug but still able to be pulled around the bar by hand.
Chain Keeps Coming Off: This could indicate a worn-out chain, a damaged bar, or incorrect chain tension.

Inspect the chain and bar for damage and adjust the chain tension as needed.

Tip #2: Supercharge Your Chain – Choosing the Right Chain

The chain is the business end of your chainsaw.

Upgrading to a higher-quality chain can significantly improve cutting speed, smoothness, and overall performance.

Just like the bar, the stock chain on many Craftsman chainsaws is often a basic model designed for general use.

Why Upgrade the Chain?

Faster Cutting: High-performance chains have sharper cutters and more aggressive designs that allow them to cut through wood more quickly.
Smoother Cuts: A well-designed chain can produce smoother, cleaner cuts with less vibration.
Longer Lifespan: High-quality chains are made from tougher materials that resist wear and tear, extending their lifespan.
Reduced Kickback: Some chains are designed with features that reduce the risk of kickback.

Types of Chains

There are several types of chainsaw chains, each designed for specific applications:

Full Chisel Chains: These chains have square-cornered cutters that are very aggressive and cut quickly.

However, they are also more prone to dulling and require more frequent sharpening.

They are best suited for clean wood and experienced users.
Semi-Chisel Chains: These chains have rounded-corner cutters that are less aggressive than full chisel chains but are more durable and less prone to dulling.

They are a good all-around choice for general use.
Low-Kickback Chains: These chains have special features that reduce the risk of kickback.

They are a good choice for inexperienced users or those who are concerned about safety.

Selecting the Right Chain

When choosing a replacement chain, consider these factors:

Chain Pitch and Gauge: The chain must match the pitch and gauge of your chainsaw bar.

As mentioned earlier, most Craftsman 18-inch chainsaws use a 0.325″ pitch and a 0.050″ gauge chain.
Type of Chain: Choose the type of chain that is best suited for your needs.

If you are cutting clean wood and want maximum cutting speed, a full chisel chain is a good choice.

If you are cutting dirty wood or are concerned about durability, a semi-chisel chain is a better option.

If you are an inexperienced user or are concerned about safety, a low-kickback chain is the safest choice.
Number of Drive Links: The chain must have the correct number of drive links to fit your chainsaw bar.

This information is usually printed on the chain packaging or can be found in your chainsaw’s manual.

Recommended Chain Brands

Oregon: Oregon is a leading manufacturer of chainsaw chains, known for their quality and performance.

Their 72LPX and 91PX chains are popular choices.
Stihl: Stihl chains are renowned for their precision and durability.

Their Rapid Micro and Rapid Duro chains are excellent options.
Husqvarna: Husqvarna chains are high-quality and offer good performance.

Their H30 and H47 chains are popular choices.

My Personal Recommendation: Oregon 72LPX Chain

For my Craftsman 18-inch chainsaw, I’d opt for the Oregon 72LPX chain. Here’s why:

Aggressive Cutting: The 72LPX is a full chisel chain that cuts incredibly fast.

I’ve used it to fell trees and buck logs with ease.
Durability: While full chisel chains are generally less durable than semi-chisel chains, the 72LPX is made from a tough alloy steel that holds its edge well.
Versatility: Despite being a full chisel chain, the 72LPX is surprisingly versatile.

I’ve used it to cut both hardwoods and softwoods with good results.

Data Point: Chain Sharpening Frequency

In my experience, a full chisel chain like the Oregon 72LPX requires sharpening more frequently than a semi-chisel chain.

On average, I sharpen my 72LPX chain after every 2-3 hours of use, while I can go 4-5 hours between sharpenings with a semi-chisel chain.

However, the increased cutting speed of the full chisel chain more than makes up for the increased sharpening frequency, in my opinion.

Step-by-Step Chain Replacement

Safety First: Always wear gloves and safety glasses.

Ensure the chainsaw is turned off and the spark plug wire is disconnected.
Loosen the Bar Nuts: Use the wrench provided with your chainsaw to loosen the bar nuts on the side cover.

Check Chain Tension: Double-check the chain tension after tightening the bar nuts.

Troubleshooting Chain Replacement

Chain is Too Short or Too Long: Ensure you have the correct number of drive links for your chainsaw bar.
Chain is Backwards: Make sure the cutting edges of the chain are facing in the correct direction.
Chain Keeps Coming Off: This could indicate a worn-out chain, a damaged bar, or incorrect chain tension.

Inspect the chain and bar for damage and adjust the chain tension as needed.

Tip #3: Oiling is Caring – Upgrading the Oiling System (If Possible)

Proper lubrication is essential for the longevity and performance of your chainsaw bar and chain.

A lack of lubrication can lead to excessive friction, heat buildup, and premature wear.

While you can’t always directly “upgrade” the oil pump itself on a Craftsman chainsaw, there are steps you can take to significantly improve the oiling system’s effectiveness.

Why Improve the Oiling System?

Reduced Friction: Adequate lubrication reduces friction between the chain and bar, allowing the chain to cut more smoothly and efficiently.
Reduced Wear: Proper lubrication extends the life of the bar and chain by reducing wear and tear.
Cooler Running: Lubrication helps to dissipate heat, preventing the bar and chain from overheating.
Improved Cutting Performance: A well-lubricated chain cuts faster and more smoothly.

Strategies for Enhancing Oiling

Use High-Quality Bar and Chain Oil: This is the most crucial step.

Don’t skimp on the oil.

Use a high-quality bar and chain oil that is specifically formulated for chainsaws.

These oils contain additives that reduce friction, prevent rust, and resist fling-off.

I personally prefer using a synthetic bar and chain oil for its superior lubricating properties and longer lifespan.
Adjust the Oiler Output (If Possible): Some Craftsman chainsaws have an adjustable oiler that allows you to control the amount of oil delivered to the bar and chain.

If your chainsaw has this feature, make sure the oiler is set to the appropriate output for the type of wood you are cutting and the ambient temperature.

In general, you should increase the oiler output when cutting hardwoods or in hot weather.
Clean the Oiler Regularly: The oiler can become clogged with debris, which can reduce its effectiveness.

Clean the oiler regularly by removing the bar and chain and using a small brush or compressed air to clean the oiler port and surrounding area.
Check the Oiler Filter: Most chainsaws have an oil filter that prevents debris from entering the oil pump.

Check the oil filter regularly and clean or replace it as needed.
Ensure Proper Bar Groove Cleaning: A clogged bar groove prevents oil from reaching the entire bar and chain.

Regularly clean the bar groove with a bar groove cleaner or a small screwdriver.
Consider an Aftermarket Oiler (Advanced): This is a more advanced upgrade, but some aftermarket oilers are available that can improve the oiling system’s performance.

These oilers typically provide a higher oil output and are more reliable than the stock oilers.

However, installing an aftermarket oiler may require some modification to your chainsaw.

My Personal Experience: The Importance of Oil

I once neglected the oiling system on my chainsaw while working on a large firewood project.

I was so focused on getting the job done that I didn’t bother to check the oil level or clean the oiler.

As a result, the chain became excessively hot, and the bar started to smoke.

Eventually, the chain seized up, and I had to replace both the bar and chain.

This costly mistake taught me the importance of proper lubrication.

Now, I make it a point to check the oil level and clean the oiler before every use.

Data Point: Oil Consumption

On average, I use about one quart of bar and chain oil for every 4-5 hours of chainsaw use.

However, oil consumption can vary depending on the type of wood you are cutting, the ambient temperature, and the oiler output setting.

It’s always better to err on the side of caution and use more oil than necessary.

Step-by-Step Oiler Cleaning

Safety First: Always wear gloves and safety glasses.

Ensure the chainsaw is turned off and the spark plug wire is disconnected.
Remove the Bar and Chain: Follow the steps outlined earlier to remove the bar and chain from your chainsaw.
Locate the Oiler Port: The oiler port is typically located on the chainsaw body, near the bar mounting studs.
Clean the Oiler Port: Use a small brush or compressed air to clean the oiler port and surrounding area.
Check the Oiler Filter: Locate the oil filter (it’s usually inside the oil tank) and remove it.

Clean the filter with solvent or replace it if necessary.
Clean the Bar Groove: Use a bar groove cleaner or a small screwdriver to clean the bar groove.
Reassemble the Chainsaw: Reinstall the bar, chain, and side cover.
Test the Oiler: Start the chainsaw and check to see if oil is being delivered to the bar and chain.

You should see a fine mist of oil being sprayed onto the bar and chain as it rotates.

Troubleshooting Oiling Problems

No Oil is Being Delivered: Check the oil level in the oil tank.

Make sure the oiler is not clogged.

Check the oil filter.

Adjust the oiler output setting (if applicable).
Oil is Leaking: Check the oil tank cap to make sure it is tight.

Inspect the oil lines for cracks or leaks.
Chain is Overheating: Make sure the chain is properly lubricated.

Sharpen the chain.

Avoid forcing the chainsaw through the wood.

Strategic Recommendations

Beyond the direct upgrades, consider these strategic recommendations for maximizing your Craftsman 18-inch chainsaw’s performance:

Master Chain Sharpening: A dull chain is a major performance killer.

Learn how to properly sharpen your chain using a file or a chainsaw sharpener.

A sharp chain cuts faster, smoother, and with less effort.
Maintain Proper Chain Tension: Proper chain tension is essential for safe and efficient cutting.

Too loose, and the chain can come off the bar.

Too tight, and the chain can overheat and wear out prematurely.
Use the Right Technique: Proper cutting technique can significantly improve your chainsaw’s performance and reduce the risk of kickback.

Always use a firm grip, keep the chainsaw close to your body, and avoid cutting with the tip of the bar.
Store Your Chainsaw Properly: Store your chainsaw in a clean, dry place.

Drain the fuel tank before storing the chainsaw for extended periods.

Use a bar cover to protect the bar and chain.
