Understanding Bar and Chain Specifications
- Bar Length: Measured in inches, indicating the cutting length of the bar.
- Pitch: The distance between three consecutive rivets divided by two, determining the size of the chain.
- Gauge: The thickness of the drive links, fitting into the bar groove.
- Drive Links: The number of links that fit into the bar’s groove.
- Bar Type: Indicates whether the bar is laminated or solid, affecting durability and weight.
- Bar Model / Part Number: Specific identifier for the bar model.
- Chain Model / Part Number: Specific identifier for the chain model.
Tips for Selecting the Right Bar and Chain
- Match Specifications: Ensure the pitch and gauge of the chain match the sprocket and bar groove dimensions.
- Consider Bar Length: Choose a bar length appropriate for the tasks you’ll perform. Longer bars are suitable for larger trees, while shorter bars offer better control.
- Check Compatibility: Always refer to the manufacturer’s recommendations for compatible bar and chain combinations.
- Maintenance: Regularly inspect and maintain your bar and chain to ensure optimal performance and safety.

FAQ
What is the most common problem with Husqvarna chainsaws?
The most common issue users face with Husqvarna chainsaws is starting trouble or stalling after starting. This can be caused by several factors, including:
- Old or bad fuel (especially if left in the tank for months)
- Clogged carburetor due to fuel residue or dirt
- Dirty air filters restrict airflow
- Flooded engine
- Improperly adjusted carburetor screws (L/H)
Regular maintenance like cleaning the air filter, using fresh fuel, and checking the spark plug can prevent many of these issues.
How do I know what bar will fit my chainsaw?
To determine what bar fits your Husqvarna chainsaw, check these key specifications:
- Bar mount type: Chainsaws have different mounts; ensure the bar’s mount pattern matches your saw.
- Pitch: Must match the chain and the drive sprocket (e.g., 3/8″, .325″).
- Gauge: This is the thickness of the drive links; common sizes are .043″, .050″, .058″.
- Drive link count: The number of drive links must fit the bar’s length and groove.

How do you match a chainsaw chain to a bar?
To correctly match a chain to your bar, you need three things:
- Pitch – The distance between chain links (e.g., 3/8″, .325″). Must match bar and sprocket.
- Gauge – The thickness of the chain drive links (e.g., .050″, .058″). Must fit snugly in the bar groove.
- Drive Links – The total number of drive links must fit the bar length and sprocket setup.
Example: If your bar is 18″, with .325″ pitch and .050″ gauge, you might need a 72-drive-link SP33G chain.
What size bar can you put on a Husqvarna 545?
The Husqvarna 545 is compatible with the following bar sizes:
- Minimum: 13” (33 cm)
- Recommended: 16” to 18”
- Maximum: 20” (50 cm)
Make sure to match the bar with the proper pitch and gauge. For the 545, it typically uses:
- Pitch: .325″
- Gauge: .050″ or .058″
- Recommended Chain: SP33G or H25 (depending on bar setup)

Why does my Husqvarna chainsaw run for a few minutes then dies?
A chainsaw that runs and then dies usually suffers from a fuel delivery issue or overheating. Common causes include:
- Clogged fuel filter or vent: Prevents proper fuel flow.
- Dirty carburetor: Affects the air/fuel mixture.
- Air leak: Around carb or crankcase, throwing off engine balance.
- Wrong carburetor tuning: L/H screws may be off (too lean or too rich).
- Bad spark plug or ignition coil
Fix tip: Clean/replace the fuel filter, check for blockages in the fuel line or vent, and clean or rebuild the carburetor.
What do the L and H mean on a chainsaw?
The L and H refer to carburetor adjustment screws:
- L (Low-speed screw): Adjusts fuel/air mix at low RPMs (idle to mid-speed).
- H (High-speed screw): Adjusts fuel/air mix at high RPMs (full throttle).
- T (Idle screw): Controls idle speed but not mixture.
Warning: Improper tuning can cause engine damage. Always consult the manual or a technician before adjusting.
Final words
Selecting the correct bar and chain combination for your Husqvarna chainsaw is essential for efficient and safe operation. By referring to the fit-up chart and understanding the specifications, you can ensure your chainsaw performs at its best.
