Description
Overview:
The Worm Wheel for Clutch & Oil Pump is a Genuine Husqvarna component designed to drive the oil pump from the clutch on professional and homeowner chainsaws. This precision-moulded gear sits behind the clutch and transfers rotation to the oiler, helping deliver steady bar and chain lubrication while maintaining smooth drivetrain operation. Made from a durable polymer for low friction and wear resistance, it offers a long service life under typical cutting conditions. Sized for a secure fit with an outer diameter of 40 mm and an inner diameter of 14 mm, it is built to Husqvarna OEM specifications for accurate alignment. It is commonly used on models such as the 550 XP and 560 XP. OEM part number: 505 20 08 01.
Key Features:
- Genuine Husqvarna OEM part (505 20 08 01) for assured fit and performance
- Drives the oil pump from the clutch to maintain consistent bar and chain lubrication
- Durable polymer construction for wear resistance and low friction in dusty, resinous environments
- Precision dimensions: 40 mm OD and 14 mm ID for correct engagement and alignment
- Helps prevent under-oiling, premature bar and chain wear, and pump damage
- Smooth, quiet operation due to accurate helical tooth profile
- Direct replacement for worn or damaged gears; like-for-like fitting with no modifications
- Supports reliable running on demanding, daily-use chainsaws
Typical Applications:
Ideal when servicing the clutch or oil pump, or when symptoms appear such as poor chain lubrication, inconsistent oil flow, or noise from the clutch side. Suitable for forestry, arborist work, landscaping, grounds maintenance, and firewood cutting. Used as preventative maintenance to keep the oiler drive reliable on busy job sites and during seasonal servicing.
