Isn’t it ironic that the tool designed to cut down trees can be so easily improved upon, evolving into something even more powerful and efficient? That’s the paradox I find myself pondering when discussing the Husqvarna 455 Rancher. A reliable workhorse straight out of the box, but with a few carefully chosen upgrades, it can transform into a true cutting beast. Let’s dive into my experiences and recommendations for maximizing the potential of this popular chainsaw.

Husqvarna Chainsaw 455 Guide: 5 Pro Bar Upgrades

The Husqvarna 455 Rancher is a staple in the world of chainsaws, known for its reliability and versatility. But even a great tool can be enhanced. I’ve spent years working with this saw, both in its stock form and with various modifications. Through trial and error, I’ve identified five bar upgrades that significantly improve its performance, durability, and overall cutting experience. This guide will walk you through these upgrades, explaining why they work, how to install them, and what to expect in terms of results.

Understanding the Stock Husqvarna 455 Rancher Bar

Before we jump into the upgrades, let’s understand the baseline. The stock Husqvarna 455 Rancher typically comes with an 18-inch bar. While perfectly adequate for general use, it has limitations. The stock bar is often a laminated bar, meaning it’s made of multiple layers of steel welded together. This construction, while cost-effective, is less rigid and durable than a solid bar. It can flex more during cuts, leading to reduced accuracy and increased wear.

The chain that comes standard is usually a .325″ pitch chain with a .050″ gauge. This is a common chain size, but it’s not always the optimal choice for every type of wood or cutting task.

My experience with the stock bar was initially positive. It handled smaller trees and firewood cutting well enough. However, when I started tackling larger trees (over 24 inches in diameter) or working with hardwoods like oak and maple, the limitations became apparent. The bar would flex, causing the chain to bind, and the cuts were often less clean and efficient. This led me on a quest to find better options.

Upgrade 1: Solid Steel Bar

The first and most impactful upgrade is switching to a solid steel bar. Unlike laminated bars, solid steel bars are made from a single piece of hardened steel. This construction provides superior rigidity, durability, and heat dissipation.

Benefits of a Solid Steel Bar:

Reduced Flex: Solid bars flex less, resulting in straighter, more accurate cuts.
Increased Durability: They are less prone to bending or breaking under stress.
Improved Heat Dissipation: Solid steel dissipates heat more effectively, prolonging bar and chain life.
Enhanced Cutting Performance: The reduced flex allows for more efficient power transfer to the chain.

Choosing the Right Solid Steel Bar:

When selecting a solid steel bar for your Husqvarna 455, consider the following:

Length: Stick with the 18-inch length if you primarily cut smaller trees and firewood. If you frequently tackle larger trees, consider a 20-inch bar.
Mounting Pattern: Ensure the bar has the correct mounting pattern for the Husqvarna 455. This is usually a “large Husqvarna” mount.
Brand: Reputable brands like Oregon, Stihl (though you’ll need to verify compatibility), and Tsumura offer high-quality solid steel bars.

Installation:

Installing a new bar is straightforward:

Remove the existing bar and chain: Loosen the bar nuts, remove the side cover, and carefully take off the bar and chain.
Clean the saw: Use a brush to remove any sawdust or debris from the bar mounting area and the chain drive sprocket.
Install the new bar: Place the new bar onto the mounting studs, ensuring it’s seated properly.
Install the chain: Drape the chain over the bar, making sure the cutting edges are facing the correct direction.
Reinstall the side cover: Place the side cover back on and tighten the bar nuts finger-tight.
Adjust chain tension: Use the chain tensioning screw to adjust the chain until it has about 1/8 inch of slack.
Tighten the bar nuts: Tighten the bar nuts securely.

My Experience:

Switching to a solid steel bar was a game-changer. The difference in cutting performance was immediately noticeable. The saw felt more stable, and the cuts were cleaner and more precise. I also noticed that the bar ran cooler, even during extended use. For me, a Oregon Pro-Lite solid bar has been the go to.

Takeaway: A solid steel bar is a must-have upgrade for any Husqvarna 455 owner looking to improve performance and durability.

Upgrade 2: Upgrading to a Full Chisel Chain

The type of chain you use significantly impacts cutting speed and efficiency. While the stock chain is adequate, upgrading to a full chisel chain can dramatically improve performance, especially in softer woods.

Understanding Chain Types:

Full Chisel: These chains have square-cornered cutters that slice through wood fibers quickly and efficiently. They are ideal for clean wood and experienced users, as they can be more aggressive and prone to kickback.
Semi-Chisel: These chains have rounded cutters that are more forgiving and less prone to kickback. They are a good choice for dirty or knotty wood.
Low-Profile (Safety) Chains: These chains have features designed to reduce kickback risk, making them suitable for inexperienced users.

Benefits of a Full Chisel Chain:

Faster Cutting: Full chisel chains cut significantly faster than other chain types.
Increased Efficiency: They require less force to cut through wood, reducing strain on the saw and the operator.
Smoother Cuts: When properly sharpened, full chisel chains produce cleaner, smoother cuts.

Choosing the Right Full Chisel Chain:

Pitch and Gauge: Ensure the chain matches the bar’s pitch and gauge. For the Husqvarna 455, this is typically .325″ pitch and .050″ gauge.
Number of Drive Links: Count the number of drive links on your existing chain and purchase a full chisel chain with the same number of links.
Brand: Oregon, Stihl, and Husqvarna all offer high-quality full chisel chains.

Installation:

Installing a new chain is the same as removing and installing the existing chain (see previous section). Be sure to pay attention to the direction of the cutting edges.

My Experience:

I initially hesitated to switch to a full chisel chain due to concerns about kickback. However, after taking the time to learn proper cutting techniques and sharpening skills, I found that the benefits far outweighed the risks. The full chisel chain sliced through wood with ease, making firewood cutting much faster and less tiring.

Takeaway: A full chisel chain is an excellent upgrade for experienced users looking to maximize cutting speed and efficiency. However, prioritize safety and proper technique.

Upgrade 3: Sprocket Nose Bar

A sprocket nose bar features a small sprocket at the tip of the bar. This sprocket reduces friction as the chain travels around the bar, resulting in smoother cutting and reduced wear.

Benefits of a Sprocket Nose Bar:

Reduced Friction: The sprocket reduces friction, allowing the chain to move more freely.
Increased Cutting Speed: The reduced friction translates to faster cutting speeds.
Reduced Wear: The sprocket minimizes wear on the bar and chain.
Improved Lubrication: The sprocket helps distribute oil more evenly along the bar.

Choosing the Right Sprocket Nose Bar:

Pitch and Gauge: Ensure the bar is compatible with your chain’s pitch and gauge (.325″ pitch and .050″ gauge for the Husqvarna 455).
Number of Teeth: The number of teeth on the sprocket affects cutting performance. A higher number of teeth generally provides smoother cutting.
Bar Length: Choose a bar length that suits your needs.
Brand: Oregon, Stihl, and Tsumura offer reliable sprocket nose bars.

Installation:

Installation is similar to installing a standard bar.

My Experience:

I found that the sprocket nose bar made a noticeable difference in cutting smoothness. The saw felt less strained, and the cuts were more consistent. I also appreciated the improved lubrication, which helped extend the life of my bar and chain.

Takeaway: A sprocket nose bar is a worthwhile upgrade for anyone looking to improve cutting smoothness, reduce wear, and enhance lubrication.

Upgrade 4: Adjustable Oiler

The Husqvarna 455 Rancher comes with a fixed-flow oiler, which means you can’t adjust the amount of oil delivered to the bar and chain. This can be problematic, especially when cutting hardwoods or using longer bars. An adjustable oiler allows you to increase the oil flow when needed, ensuring adequate lubrication and preventing premature wear.

Benefits of an Adjustable Oiler:

Customizable Lubrication: Adjust the oil flow to match the wood type, bar length, and cutting conditions.
Reduced Wear: Proper lubrication prevents excessive wear on the bar, chain, and sprocket.
Improved Cutting Performance: Adequate lubrication reduces friction, resulting in smoother and more efficient cutting.
Extended Bar and Chain Life: By preventing overheating and wear, an adjustable oiler can significantly extend the life of your bar and chain.

Finding an Adjustable Oiler:

Unfortunately, Husqvarna doesn’t offer a direct adjustable oiler replacement for the 455 Rancher. However, some aftermarket options exist, or you might be able to modify the existing oiler. This modification typically involves adjusting the oil pump’s internal components to increase the flow rate.

Installation:

Installing or modifying the oiler can be complex and may require some mechanical skill. If you’re not comfortable performing this task yourself, it’s best to consult a qualified chainsaw mechanic.

My Experience:

I found that my stock oiler wasn’t sufficient for cutting hardwoods with a 20-inch bar. I ended up modifying the oil pump to increase the flow rate. This involved disassembling the pump and carefully adjusting a small screw that controlled the oil flow. The modification made a significant difference, and I no longer had issues with overheating or excessive wear. Disclaimer: Modifying your chainsaw can void the warranty and potentially affect its performance. Proceed with caution and at your own risk.

Takeaway: An adjustable oiler is a valuable upgrade for those who frequently cut hardwoods or use longer bars. However, installation or modification can be challenging and should be performed by someone with mechanical expertise.

Upgrade 5: Bar and Chain Combo Kit

Sometimes, the easiest and most cost-effective way to upgrade your bar and chain is to purchase a combo kit. These kits typically include a high-quality bar, a matching chain, and sometimes even a file for sharpening.

Benefits of a Bar and Chain Combo Kit:

Convenience: Everything you need in one package.
Cost Savings: Combo kits are often cheaper than buying the bar and chain separately.
Guaranteed Compatibility: The bar and chain are designed to work together perfectly.
Improved Performance: The matched components can enhance cutting performance and efficiency.

Choosing the Right Bar and Chain Combo Kit:

Bar Length: Select a bar length that suits your needs.
