Husqvarna Bevel Gear Grease 100 g Tube — OEM lubricant for trimmers & brushcutters, resists water and wear

Husqvarna Genuine Bevel Gear Grease is a 100 g OEM lubricant formulated to protect the lower-head bevel gears in Husqvarna string trimmers and brushcutters for smoother operation and longer component life.

Whether you service a single trimmer or an entire fleet, using the manufacturer-specified bevel gear grease ensures proper viscosity, gear protection and compatibility with Husqvarna gear housings. This 100 gram tube (part number 503976401) is sized for routine maintenance and comes as the exact grease Husqvarna recommends for models including 223R, 223LUSA, 223L, 153R, 143RII, 143R, 142R, 133R, 132RJ, 132R, 123LD, 123L and 123C.

How does this grease protect bevel gears during heavy use?

The grease forms a durable film that reduces metal-to-metal contact and resists washout in dusty or wet conditions. It helps control friction and heat at the bevel gear interface, which lowers wear and helps maintain cutting performance over time.

• OEM formulation matched to Husqvarna gear materials
• Maintains viscosity under load to prevent gear scoring
• Resists water and debris intrusion better than generic lubricants

How do I apply the 100 g tube to my trimmer or brushcutter?

Applying this grease is straightforward: remove the lower gear housing, clean old lubricant and contaminants, then apply a thin, even layer to the bevel gears before reassembly. Use only the amount recommended in your operator manual to avoid excess build-up.

• Clean gears with a suitable solvent, then dry thoroughly
• Pack gear teeth lightly; avoid overfilling the housing
• Reassemble housing and check for smooth rotation before use

How much grease do I need and when should I reapply?

The 100 g tube provides enough grease for several standard lower-gear servicing jobs, depending on how much is used per housing. Reapply whenever you perform maintenance, if you hear grinding or rough rotation, or at intervals recommended in your equipment manual.

• 100 g tube suitable for multiple servicing cycles
• Check gears every 25–50 hours of operation or per manual
• Reapply after water immersion or heavy debris exposure
