Guide Bar Makita 191G45-2, 38 cm length, 1.5 mm gauge, .325" pitch

Replacement guide bar Makita 191G45-2, 38 cm length, 1.5 mm gauge, .325" pitch is a spare guide bar designed for use with chainsaws that accept a 15-inch bar with a 1.5 mm nose gauge and .325" chain pitch. It restores correct chain alignment, supports consistent cutting performance and helps maintain safe operation during timber cutting and pruning. The bar is compatible with appropriate Makita models and other brands that use the same bar dimensions and pitch.

Advantages

The guide bar provides a durable steel construction that resists bending under load and promotes stable chain tracking. Its 38 cm length balances cutting reach and maneuverability for general-purpose forestry and garden tasks. The 1.5 mm gauge and .325" pitch ensure compatibility with common medium‑duty chains, reducing the need for adapter components. The replacement bar is intended to restore factory geometry and improve cutting accuracy when fitted and tensioned correctly.

Suitable for

• General timber felling and limbing with chainsaws that accept a 38 cm / 15 in bar
• Garden pruning and cutting of medium-sized logs and branches
• Replacing worn or damaged guide bars to restore chain alignment and cutting performance
• Use in maintenance or repair of compatible Makita and other-brand chainsaws with matching bar specifications

Key specifications

• Bar length: 38 cm (15 in)
• Gauge (guide groove width): 1.5 mm
• Chain pitch: .325 inch
• Material: hardened steel guide bar construction
• Bar type: replacement guide bar for sprocket-nose or round-nose chains depending on model fit

How to use

Fit the guide bar by first removing the saw chain and the old bar according to the chainsaw manufacturer's instructions. Place the new guide bar onto the studs, route the chain around the sprocket and bar, then mount the chain onto the bar groove. Adjust chain tension to the recommended specification while cold, ensuring the chain moves freely but without sagging. Verify sprocket alignment and secure the bar nuts to the specified torque. Perform a test cut and recheck tension after initial use.

Usage recommendations

Use chains and drive sprockets matched to a 1.5 mm gauge and .325" pitch. Regularly inspect the bar for wear at the rail, nose and oil holes; maintain proper lubrication of the bar and chain to reduce wear. Replace the bar if significant bending, wear in the groove, or damage to the nose sprocket area is observed. Follow the chainsaw manufacturer's safety and maintenance guidelines when fitting and using this guide bar.
