Review VICTOR REINZ Mercedes benz Rear Crankshaft Seal fits 560SEL 1990–1991

The **Victor Reinz 81-22887-00** is a high-performance, precision-engineered rear crankshaft seal designed specifically for Mercedes-Benz 560 SEL models produced between 1990 and 1991. This seal is a critical component of the vehicle s drivetrain, ensuring a reliable and leak-free connection between the transmission and the rear differential, thereby maintaining optimal hydraulic pressure and preventing contamination within the differential housing. Crafted from Victor Reinz s proprietary **high-grade nitrile rubber compound**, this seal is engineered to withstand the demanding conditions of high torque, extreme temperatures, and prolonged exposure to lubricants, oils, and transmission fluids without degrading or cracking. The seal features a **reinforced lip design** with a precision-molded, self-adjusting profile that guarantees a consistent, airtight seal even as the crankshaft operates under varying loads and vibrations, a common challenge in high-performance luxury vehicles like the 560 SEL. Its **metal-reinforced outer flange** provides structural integrity, preventing deformation during installation and ensuring long-term durability, while the **smooth, low-friction inner bore** minimizes wear on the crankshaft, reducing the risk of premature failure. Ideal for both original equipment replacement (OEM) and aftermarket upgrades, this seal is compatible with the **M235/M236 7-speed automatic transmissions** found in these models, offering superior performance over generic or lower-quality alternatives. Whether addressing a leaking seal, preparing for a transmission rebuild, or upgrading for enhanced reliability, the Victor Reinz 81-22887-00 delivers the precision, longevity, and leak-proof performance that Mercedes-Benz enthusiasts and professional mechanics demand.

The **Victor Reinz 81-22887-00** is a common aftermarket replacement for the rear crankshaft seal (also called the oil pump seal) on the **Mercedes-Benz 560 SEL (W126) from 1990 1991**. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
