Jonsered 630 Chainsaw: Essential Parts Guide (7 Pro Tips)

The Jonsered 630 is a legend for a reason. Its robust design and powerful engine made it a favorite among professionals and serious hobbyists alike. Understanding its core components is crucial not only for maintenance but also for troubleshooting and ensuring its continued performance.

1. The Heart of the Beast: Engine Components

The engine is arguably the most crucial part of any chainsaw, and the Jonsered 630 is no exception. Let’s break down the key components:

• Cylinder and Piston: This is where the magic happens – the combustion that drives the chain. Over time, the cylinder can become scored or the piston rings worn, leading to reduced power and efficiency.

  • Cost Considerations: Replacing the cylinder and piston is a significant expense. I’ve seen aftermarket kits ranging from $80 to $200, while genuine Jonsered parts can easily double that price. Pro Tip: Always check the condition of the cylinder when inspecting a used 630. Look for scoring or excessive wear.

  • Carburetor: The carburetor mixes fuel and air for optimal combustion. A dirty or malfunctioning carburetor can cause starting problems, poor idling, and reduced power.

  • Cost Considerations: Carburetor rebuild kits are relatively inexpensive, usually around $20-$40. A complete replacement carburetor can cost between $50 and $100. Pro Tip: Before replacing the carburetor, try cleaning it thoroughly with carburetor cleaner. Often, this simple step can restore its functionality.

  • Ignition System (Coil, Spark Plug): This system provides the spark that ignites the fuel-air mixture. A faulty coil or spark plug can prevent the saw from starting or cause it to run poorly.

  • Cost Considerations: Spark plugs are cheap – usually just a few dollars. Ignition coils, however, can cost between $30 and $70. Pro Tip: Always use the correct type of spark plug recommended by Jonsered. This will ensure optimal performance and prevent damage to the engine.

  • Fuel System (Fuel Lines, Fuel Filter): The fuel system delivers fuel from the tank to the carburetor. Cracked or clogged fuel lines and filters can starve the engine of fuel.

  • Cost Considerations: Fuel lines and filters are inexpensive, typically costing only a few dollars each. Pro Tip: Replace the fuel filter regularly, especially if you’re using fuel that’s been stored for a while.

2. The Cutting Edge: Bar and Chain

The bar and chain are the business end of the chainsaw, responsible for actually cutting the wood.

• Guide Bar: The guide bar supports and guides the chain. Over time, the bar can become worn, bent, or damaged.

  • Cost Considerations: The price of a new guide bar depends on its length and quality. Expect to pay between $30 and $80 for a decent replacement bar. Pro Tip: Regularly clean the bar groove and check for burrs or damage. Filing off any burrs can extend the life of the bar.

  • Chain: The chain is the cutting component, consisting of numerous cutters linked together. A dull or damaged chain will make cutting difficult and increase the risk of kickback.

  • Cost Considerations: Chains vary in price depending on their length, type, and quality. A good quality chain for the Jonsered 630 will cost between $20 and $50. Pro Tip: Learn how to sharpen your own chains. This will save you money and keep your saw cutting efficiently.

  • Chain Tensioner: This mechanism allows you to adjust the tension of the chain. A malfunctioning tensioner can make it difficult to keep the chain properly tensioned.

  • Cost Considerations: Replacement chain tensioners can cost between $15 and $30. Pro Tip: Lubricate the chain tensioner mechanism regularly to prevent it from seizing up.

3. Power Transmission: Clutch and Sprocket

The clutch and sprocket transmit power from the engine to the chain.

• Clutch: The clutch engages and disengages the chain, allowing the engine to idle without the chain spinning. A worn or damaged clutch can cause the chain to slip or not engage properly.

  • Cost Considerations: Replacement clutches typically cost between $30 and $60. Pro Tip: Inspect the clutch shoes regularly for wear. Replace them if they are worn thin or cracked.

  • Sprocket: The sprocket drives the chain around the bar. A worn sprocket can damage the chain and reduce cutting efficiency.

  • Cost Considerations: Sprockets are relatively inexpensive, usually costing between $10 and $20. Pro Tip: Replace the sprocket whenever you replace the chain. This will ensure optimal chain performance.

4. Safety First: Brake System

The chain brake is a crucial safety feature that stops the chain instantly in the event of kickback.

• Chain Brake Band and Handle: The brake band is the component that physically stops the chain. The handle activates the brake.

  • Cost Considerations: Replacement brake bands and handles can cost between $20 and $40 each. Pro Tip: Test the chain brake regularly to ensure it’s functioning properly.

5. Vibration Dampening: AV Mounts

The Jonsered 630 features an anti-vibration (AV) system to reduce operator fatigue.

• AV Mounts (Rubber Bushings): These rubber bushings isolate the engine and cutting components from the handles, reducing vibration.

  • Cost Considerations: Replacement AV mounts can cost between $5 and $15 each. Pro Tip: Inspect the AV mounts regularly for cracks or wear. Replace them if they are damaged.

6. Keeping it Cool: Cooling System

The cooling system prevents the engine from overheating.

• Cooling Fins and Fan: Cooling fins on the cylinder dissipate heat, while a fan circulates air around the engine.

  • Cost Considerations: These components are usually durable, but the fan can be damaged by debris. Replacement fans typically cost between $20 and $40. Pro Tip: Keep the cooling fins clean to ensure proper airflow.

7. Exhaust System: Muffler

The muffler reduces noise and directs exhaust gases away from the operator.

• Muffler: The muffler can become clogged with carbon deposits over time, reducing engine performance.

  • Cost Considerations: Replacement mufflers can cost between $30 and $80. Pro Tip: Clean the muffler regularly to prevent carbon buildup.

Pro Tips for Maintaining Your Jonsered 630

Here are seven pro tips to help you keep your Jonsered 630 running smoothly:

1. Use High-Quality Fuel and Oil: Always use fresh, high-octane gasoline and a high-quality two-stroke oil mixed at the correct ratio. This will protect the engine from wear and tear. I’ve personally found that using premium fuel makes a noticeable difference in engine performance and longevity.
2. Clean the Air Filter Regularly: A dirty air filter restricts airflow to the engine, reducing power and efficiency. Clean the air filter after each use, or more often if you’re working in dusty conditions.
3. Sharpen the Chain Regularly: A sharp chain cuts faster, safer, and more efficiently. Learn how to sharpen your own chains or take them to a professional.
4. Lubricate the Bar and Chain: Use a high-quality bar and chain oil to keep the chain lubricated and prevent wear. Check the oil level frequently and refill as needed.
5. Inspect and Maintain the Saw Regularly: Before each use, inspect the saw for any signs of damage or wear. Check the chain tension, bar condition, and all safety features.
6. Store the Saw Properly: When not in use, store the saw in a clean, dry place. Drain the fuel tank or add fuel stabilizer to prevent fuel from going stale.
7. Don’t Neglect Safety Gear: Always wear appropriate safety gear when operating a chainsaw, including eye protection, hearing protection, gloves, and chaps. I once saw a friend get a nasty cut because he wasn’t wearing chaps – a painful lesson learned.
