The Wacker Neuson is a genuine OEM Shaft Seal 1.62 X 2.46 X.25 9A designed for RD12, RD16, and CB14B series tandem vibratory rollers. Sourced directly from Wacker Neuson, this seal carries the exact dimensional profile and material specification required to maintain a proper hydraulic or drivetrain shaft seal in these machines. It fits a wide range of RD and CB14B configurations including hydrostatic, double-drum, foldable ROPS, and solid ROPS variants. When your seal shows signs of weeping, leaking, or contamination ingress, replacing it with part number restores the original sealing integrity without compromise.
Key Features
- Exact Dimensional Match: — Dimensioned at 1.62 x 2.46 x .25 inches with a 9A lip profile, ensuring the seal seats flush and compresses correctly within the original housing bore.
- Genuine OEM Construction: — Manufactured to Wacker Neuson's material grade and compression tolerance specifications, so sealing contact pressure holds up under continuous vibratory roller operating conditions.
- Broad RD and CB14B Series Coverage: — Confirmed fit across RD11A, RD11AEC, RD11V, RD12-90, RD12A-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 tandem roller configurations.
- Prevents Fluid Loss and Contamination: — A failed shaft seal allows lubricant or hydraulic fluid to escape and opens the shaft to dirt and debris ingress, which accelerates bearing and shaft wear in the drum drive system.
- Direct OEM Replacement: — Drops into the original seal location with no reworking of the housing, maintaining the shaft-to-bore clearance that Wacker Neuson engineered into these roller platforms.
A shaft seal forms the barrier between a rotating shaft and its surrounding housing, keeping lubricating fluid in and contaminants out. In a tandem vibratory roller like the RD and CB14B series, the drum drive shafts operate under sustained load and vibration, making seal integrity critical to the longevity of the surrounding drivetrain components. When the seal degrades — through heat cycling, age, or mechanical wear — fluid leaks begin, lubrication is lost from the bearing surfaces, and abrasive particles can work their way in, accelerating internal damage. Replacing a worn seal promptly with the correct part, 5000079721, is one of the most cost-effective ways to protect the broader drivetrain assembly.
