Description
Over time, the constant mechanical rotation, high casing heat, and crankcase pressures wear down the front drive spigot rubber, causing a steady weep of engine oil. For riders running these classic 125cc or 250cc power units, updating these worn components provides an immediate maintenance fix. This package is configured to offer a completely oil-tight barrier, keeping your engine cases clear of grime and ensuring your rear wheel surface remains free from greasy road films.

🔧 Install Tips
- Sprocket Orientation: Pay attention to alignment when reassembling. Ensure the raised internal shoulder offset of your drive sprocket faces completely outwards, away from the engine casings.
- Casing Preparation: Meticulously wipe down the engine output shaft splines and inner housing recess to clear away packed road sludge before pushing the replacement seals home.
- Careful Extraction: Use a suitable smooth pry tool to ease the old hardened seals from their seating border. Avoid scratching or scoring the surrounding cast aluminium engine casing.
- Component Reference Cross-Match: Works to replace original component records 09280-26003 and 09280-19005.
