Oil drive pump worm gear fits Husqvarna 445 and 450 chainsaws. The worm gear sits on the crankshaft and drives the oil pump rotor by direct mesh engagement, maintaining a continuous flow of bar and chain oil to the guide bar during cutting. On the 445/450 series the gear is a model-specific profile confirm against your old part before ordering. Worn or stripped teeth on the worm gear break the drive connection to the oil pump, resulting in a dry guide bar and chain lubrication failure. Because the engine continues to run normally, oil starvation caused by a failed worm gear can go unnoticed until visible wear appears on the bar rails or drive links. Replacing the gear is a straightforward fix that restores full oil pump drive without replacing the entire pump assembly.
