This component is a specialized Oil Seal (Shaft Seal) that provides a critical barrier against oil leakage around the moving shaft of the Planetary Gear Control Cylinder within the Scania heavy-duty gearbox. It is essential for protecting the pneumatic shifting mechanism from transmission oil and maintaining the proper function of the gear range splitter. Replacing this seal (OE 1784975 / 1530297) is necessary during any overhaul of the range change cylinder to ensure the transmission remains leak-free and the shifting system operates reliably in vehicles like those equipped with GRS895, GRS/GRSO905, and GRSO925 transmissions.

📌 OE Reference Number: 1784975, 1530297

📌 Suitable Vehicle Model: Scania P, G, R, T-Series trucks equipped with various GRS and GRSO transmissions:

• GRS895/R
