Yato YT-849333 Chainsaw Guide Bar 50cm 20-inch .325-inch 0.05-inch 78 Drive Links

The Yato YT-849333 chainsaw guide bar is a high-performance replacement component engineered for reliability and precision in wood-cutting tasks. Measuring 50 cm (20 inches) in length, this guide bar is constructed from durable 65Mn manganese steel, which provides exceptional resistance to abrasion and heat, ensuring a longer service life even under demanding conditions. Designed to integrate seamlessly with various chainsaw models, it features an automatic chain lubrication system that minimizes operating friction and enhances cooling for the entire cutting assembly.

Advantages

The primary benefit of this guide bar is its robust manganese steel construction, which significantly improves durability and resistance to wear during intensive use. The integrated automatic lubrication system is a critical feature that reduces heat buildup and friction, thereby protecting the chain and the bar from premature damage. Its design ensures stable and precise cutting performance, making it a dependable choice for both professional forestry work and routine garden maintenance. The compatibility with standard U-type mounts allows for versatile application across different equipment setups.

Suitable for

• Professional forestry and tree felling
• Routine garden maintenance and wood preparation
• Domestic firewood cutting
• General construction and carpentry tasks involving chainsaws

When it may not be suitable

This guide bar is specifically designed for chainsaws requiring a .325-inch pitch and a 0.05-inch gauge. It will not be suitable for chainsaws that require different pitch or gauge specifications, as this would prevent the chain from seating correctly and could lead to equipment failure or safety hazards.

Key specifications

• Length: 50 cm (20 inches)
• Pitch: .325 inches
• Gauge: 0.05 inches (1.3 mm)
• Drive links: 78
• Material: 65Mn manganese steel
• Mount type: U-type (K095)

How to use

To install the guide bar, first ensure the chainsaw is powered off and the spark plug wire is disconnected for safety. Remove the side cover of the chainsaw and loosen the tensioning mechanism to remove the old bar and chain. Align the Yato guide bar with the mounting studs, ensuring the oil delivery hole aligns with the chainsaw's lubrication port. Place the chain over the sprocket and into the groove of the guide bar, then replace the side cover. Adjust the chain tension so that it is snug but can still be pulled slightly away from the bar. Tighten the mounting nuts securely before operation.

What to consider before purchase

• Verify that your chainsaw model is compatible with the U-type (K095) mounting system.
• Confirm that your chainsaw requires a .325-inch pitch and 0.05-inch gauge chain.
• Ensure the drive link count of 78 matches your specific chain requirements.
• Check the condition of your drive sprocket to ensure it is compatible with the .325-inch pitch.

Usage recommendations

For optimal performance and longevity, it is recommended to pair this guide bar with Yato YT-849453 chains. Always maintain proper chain tension and ensure the automatic lubrication system is functioning correctly before every use. Regularly clean the guide bar groove to prevent debris buildup.
