Wacker Neuson 5000079791 Shaft Seal 140 X 160 X 12

The Wacker Neuson Shaft Seal 140 X 160 X 12 is a genuine OEM component designed for the RS800 series single drum vibratory rollers. As a direct OEM replacement, this seal is manufactured to the same material grade and dimensional tolerances as the original, ensuring a correct, leak-free fit in the drum drive or transmission assembly. Verified fitment covers the RS800, RS800A, RS800H, RS800V, and RSS800A models. Always confirm your machine's serial number and model designation before ordering to ensure this is the correct seal for your application.

Key Features

• OEM-Grade Seal Material: — Manufactured to the original compression rating and material specification, maintaining the sealing integrity expected of factory components in a high-vibration roller application.
• Exact Dimensional Match: — At 140 x 160 x 12 mm, this seal installs directly into the original bore without machining or modification to the housing.
• Broad RS800 Series Coverage: — Confirmed fitment across RS800, RS800A, RSS800A, RS800H, and RS800V single drum vibratory roller models.
• Protects Critical Drive Components: — A properly functioning shaft seal prevents lubricant loss and contamination ingress at the shaft, protecting bearings and gears from accelerated wear.
• Fluid Containment Compliance: — A worn or failed shaft seal can allow oil to migrate onto drum or ground surfaces, creating a safety hazard and risking environmental non-compliance on regulated worksites.

A shaft seal forms a dynamic barrier between a rotating shaft and its surrounding housing, preventing lubricant from escaping the gearbox or drum drive assembly while blocking dirt, water, and debris from entering. In a single drum vibratory roller like the RS800 series, the shaft seal operates under sustained rotational load and vibration stress, making material quality and dimensional accuracy critical to service life. When a shaft seal fails, oil loss accelerates bearing wear, and contamination can cause rapid damage to internal drive components — making prompt replacement essential to keep the roller operating at full compaction performance.
